DM-CJ08 8-Port M12 Junction Box, IP67

Sat, 31 Oct 2026 09:33:25 +0000

Overview

The DM-CJ08 collects eight sensor cables into one multi-core home run, which reduces the number of cables entering a cabinet from eight to one and makes a machine section easier to isolate and service. Each port has an LED so a technician can see the signal state without opening the box.

The housing is PBT with a gasket and stainless screws, rated IP67 in the mated condition. Ports are 3, 4 or 5-pin M12, and the home run is a fixed 5 m or 10 m cable with a connector or flying leads.

Key features

8 x M12 ports, 3/4/5-pin configuration
Single home-run cable to the cabinet
Per-port LED indication
IP67 PBT housing with stainless fasteners
2 A per port, 30 V AC/DC
Optional stainless housing for washdown and chemical areas

Typical applications

Sensor clusters on conveyor sections
End-effector and gripper wiring consolidation
Pump station instrument collection
Machine sections with frequent changeover

Selection note

A passive box carries the signals only; it does not condition or isolate them. If the sensors are far from the cabinet or the environment is electrically noisy, use a master with per-port diagnostics, or add an isolating conditioner at the cabinet end.

DM-SD24 Loop-Powered Digital Indicator with 2 Relays

Sat, 31 Oct 2026 09:33:24 +0000

Overview

The DM-SD24 takes its power from the current loop it is measuring, so installing it means breaking the loop and inserting the indicator, nothing more. It displays the scaled value in engineering units and provides two relays that can be set as high, low or window alarms with adjustable hysteresis and delay.

That combination replaces a separate display and trip amplifier in many panels. It is particularly useful on remote or skid-mounted equipment where an operator needs to see the value and where a local alarm must act even if the control system is offline.

Key features

Two-wire, loop-powered, no separate supply required
4-digit display with configurable engineering units and scaling
Two relays configurable as high, low or window alarm
Adjustable hysteresis and 0-60 s alarm delay
IP65 front face for panel or field mounting
Voltage drop of only 2.5 V, minimising loop burden

Typical applications

Local readout on pump and valve skids
Over-temperature and dry-run alarms
Level indication on remote tanks
Flow totalising display at a metering point

Loop budget note

A two-wire indicator adds to the loop resistance. Check that the transmitter’s minimum supply voltage plus the indicator’s voltage drop plus the cable and sense resistor still falls below the available supply, especially on 12 V loops.

DM-CB05 M12 5-Pin Shielded Sensor Cable, 5 m PUR

Sat, 31 Oct 2026 09:33:24 +0000

Overview

The DM-CB05 is an overmoulded five-pin cordset for standard sensor connections. The moulded body seals the conductor entry permanently, which removes the gland that is responsible for most water ingress in field-wired connectors, and the PUR jacket resists coolant, oil and repeated flexing.

Shielding is included as standard, because the cost difference against unshielded cable is small and the benefit in any panel with a drive is large. The shield is bonded to the coupling nut so it terminates at the sensor housing and at the panel gland.

Key features

M12 A-coded, 5-pin, straight or 90° angled
Shielded construction with braid coverage over 85%
PUR jacket resistant to coolant, oil and UV
IP69K in the mated condition
2 A per contact, 30 V AC/DC rated
Available in 0.3, 2, 5 and 10 m lengths from stock

Typical applications

Sensor and actuator connections on machine tools
Washdown areas in food and beverage plants
Gripper and end-effector wiring
IO-Link device connections at 230 kbit/s

Installation note

Tighten the coupling nut by hand and then a quarter turn; over-tightening distorts the seal and under-tightening lets water in. Respect the bend radius at the connector body, because the failure point on a moulded cordset is where the cable leaves the moulding.

DM-PC18 M18 Capacitive Proximity Sensor, 8 mm, IO-Link

Sat, 31 Oct 2026 09:33:19 +0000

Overview

The DM-PC18 detects what an inductive sensor cannot: plastic containers, glass bottles, cardboard, wood and bulk material. The sensing field is capacitive, so any material with a dielectric constant above about 1.5 will trigger it, and the sensitivity potentiometer or IO-Link parameter sets the threshold for the specific product.

The IO-Link version matters on lines with frequent product changes. Instead of an operator adjusting a potentiometer behind a guard, the switching threshold and the output logic are stored in the recipe and downloaded over IO-Link when the product changes.

Key features

8 mm adjustable sensing distance, non-flush mountable
Detects plastics, glass, wood, paper and liquids
IO-Link 1.1 parameterisation plus PNP switching output
Sensitivity adjustment by potentiometer or IO-Link
IP67 PBT housing with M12 connector
Switching frequency 100 Hz, suited to presence detection

Typical applications

Bottle, cap and label presence on filling lines
Level detection through a plastic tank wall
Cardboard and wood board detection in packaging
Product changeover with recipe-based thresholds

Application note

Capacitive sensors are affected by humidity and by product residue on the face. Mount them where the face stays clear, and use IO-Link diagnostics to detect a threshold that is drifting before it causes a missed detection.

DM-PX12 M12 Inductive Proximity Sensor, 4 mm, IP69K

Sat, 31 Oct 2026 09:33:18 +0000

Overview

The DM-PX12 is the workhorse of the range: an M12 barrel sensor in a 304 stainless housing, flush mountable, with a 4 mm sensing distance on mild steel. The oscillator, output stage and protection circuitry are potted into the barrel, so vibration and moisture have nothing to work loose.

The IP69K rating applies to the sensor and its connector together, which is why the M12 connector version is specified for washdown areas rather than a cable tail with a gland. Output is PNP normally open, with NPN and two-wire versions available in the same housing.

Key features

4 mm flush sensing distance on mild steel, 2 mm on stainless
PNP NO output, 200 mA, short-circuit and reverse-polarity protected
IP69K with an IP69K cordset fitted
1 kHz switching frequency, 10-30 VDC supply
304 stainless barrel, -25 to +70 °C ambient
LED indication visible from three sides

Typical applications

Clamp, slide and end-stop position on machine tools
Part presence on conveyors and transfer stations
Gripper and tool-changer confirmation
Door and guard position on washdown equipment

Mounting note

Flush mountable sensors can be embedded in metal without a free zone, but leave at least one sensing distance between two adjacent sensors to avoid mutual interference. On aluminium or stainless targets, expect the sensing distance to fall by 30-50% and specify an extended-range model if the gap is tight.

DM-LF120 Capacitive Level Switch for Liquids and Powders

Sat, 31 Oct 2026 09:33:17 +0000

Overview

The DM-LF120 detects the presence or absence of material at a single point. A rod probe forms one plate of a capacitor and the vessel wall the other, so when product covers the rod the capacitance changes and the output switches. There are no moving parts and nothing to jam, which is why capacitive switches are used on powders and sticky media where a float would fail.

Sensitivity is adjustable to compensate for a low dielectric constant or for build-up on the probe. The standard output is PNP, with relay and NAMUR versions available for interlock circuits and hazardous areas.

Key features

Point-level detection for liquids, granules and powders
Adjustable sensitivity for media with low dielectric constant
PNP, relay or NAMUR output
Stainless steel or PTFE-coated rod, lengths 100-1,000 mm
Build-up compensation via sensitivity adjustment
IP67 with M12 connector

Typical applications

High-level alarm on tanks and silos
Dry-run protection on pumps and dosing systems
Powder and granule presence in hoppers
Interface detection between two liquids

Selection note

Capacitive switching depends on the dielectric constant of the medium. Water at 80 is easy; oils at 2.2 and plastic pellets at 2.0 are marginal and need a coated probe or a different technology. State the medium when ordering so the probe length and sensitivity are set at the factory.

DM-LR60 80 GHz Radar Level Transmitter, 0-30 m

Sat, 31 Oct 2026 09:33:16 +0000

Overview

The DM-LR60 uses an 80 GHz frequency-modulated continuous-wave radar to measure the distance to a liquid or solid surface without contact. The short wavelength gives a narrow 4° beam, which is what allows the transmitter to be mounted in a tank with agitators, heating coils and inlet streams without picking up a reflection from any of them.

Because the measurement is electromagnetic rather than acoustic, vapour, dust, foam and wind have far less effect than they do on an ultrasonic sensor. Setup is done over Bluetooth from a phone or over HART from the control system, and the empty and full calibration can be entered as distances rather than as percentages, which removes a common source of configuration error.

Key features

0-30 m range with ±3 mm accuracy
80 GHz FMCW, 4° beam angle
Unaffected by vapour, dust and most foam
4-20 mA with HART 7 and Bluetooth configuration
PTFE or PFA antenna for corrosive media
Process temperature -40 to +150 °C, pressure -1 to 40 bar

Typical applications

Wet wells, sumps and pump stations
Fermentation and buffer tanks with foam
Silo and hopper inventory for powders and pellets
Chemical storage tanks with corrosive vapours

Mounting note

Keep the antenna clear of the tank wall by at least 100 mm and away from the inlet stream. A nozzle that protrudes more than its own diameter into the tank creates a false echo that no configuration can remove, so shorten the nozzle or use a flush antenna.

DM-FT80 Turbine Flow Meter, 1/2″-2″

Sat, 31 Oct 2026 09:33:15 +0000

Overview

The DM-FT80 is a small-line turbine meter for clean, low-viscosity liquids: fuels, solvents, water, glycol and light oils. A free-running rotor turns in proportion to flow, and a Hall-effect sensor picks up the blade passage without contact, so there is no wear element in the signal path and the pulse output drops straight into a totaliser or PLC counter.

The body is 316L stainless with a tungsten carbide shaft and a sapphire bearing on the standard version, which keeps the calibration stable in clean service. Each meter is wet-calibrated, and the K factor is marked on the body and stored in the electronics where a display version is fitted.

Key features

±0.5% of reading over the calibrated range, 10:1 turndown
1/2″ to 2″ line sizes, BSP or NPT connections
Tungsten carbide shaft and sapphire bearing
Pulse, 4-20 mA and local totaliser options
Wet-calibrated with the K factor marked on the housing
-20 to +120 °C media temperature, 40 bar rating

Typical applications

Diesel, kerosene and lubricant dispensing
Coolant and glycol filling on assembly lines
Chemical dosing and batch totalising
Test rig fuel consumption measurement

Application limits

A turbine meter needs clean liquid. Grit, fibres or crystallising media will wear or seize the rotor, and the calibration will drift without any alarm. If the media is not clean, use an electromagnetic or clamp-on ultrasonic meter instead, even at a higher cost.

DM-TT200 Head-Mount Temperature Transmitter, 4-20 mA / HART

Sat, 31 Oct 2026 09:33:13 +0000

Overview

The DM-TT200 converts an RTD or thermocouple signal into a 4-20 mA loop inside the connection head, metres away from the measurement point. That short analogue path is the whole point: the low-level sensor signal stays inside a shielded head instead of travelling down a cable next to a drive, and the control system receives a robust current loop.

The input is universal and configured by software, covering PT100, PT1000, Ni1000, thermocouple types K, J, T, E, N, R, S, B, and millivolt or resistance inputs. Sensor matching (Callendar-Van Dusen coefficients) can be entered for a specific probe, which brings a standard Class A element closer to a calibrated pair without buying a tighter element.

Key features

Universal input: RTD, thermocouple, mV, resistance
4-20 mA output with HART 7 digital communication
1,500 VAC galvanic isolation between input and output
Sensor matching via CVD coefficients for individual probes
Sensor break and short-circuit detection with configurable drive
Fits DIN B connection heads, 34 mm diameter, 22 mm height

Typical applications

Process temperature loops on RTD and thermocouple probes
Retrofit of direct-wired RTDs onto an existing 4-20 mA card
Hazardous-area loops with intrinsic safety barriers
Sanitary probe assemblies in food and pharmaceutical service

Commissioning note

Configure the input type and range before installation, then verify the loop current at two points. A transmitter configured for a 3-wire PT100 on a 4-wire probe will read a plausible but wrong value, which is harder to find later than an outright failure.

DM-TS100 PT100 RTD Probe, -50 to +400 °C

Sat, 31 Oct 2026 09:33:12 +0000

Overview

The DM-TS100 is a general-purpose platinum resistance probe for process and utility temperature measurement. The element is a Class A PT100 in a 6 mm 316L stainless sheath, wired 4-wire so the lead resistance cancels out and the reading does not change when the cable length changes.

The probe is available with a fixed G1/2 thread or a spring-loaded compression fitting that holds the tip against the pipe wall or thermowell bottom. Spring loading removes the air gap that causes slow and low readings on immersion probes, which is the most common installation error in temperature measurement.

Key features

Class A PT100 element, ±0.15 °C at 0 °C, 4-wire connection
6 mm 316L stainless sheath, length 100 to 500 mm
Response time t90 = 8 s in flowing water
G1/2 thread, spring-loaded compression fitting or clamp connection
-50 to +400 °C range, IP67 connection head
Optional 3-point calibration certificate

Typical applications

Hot water and steam line temperature
Bearing and gearbox temperature monitoring
HVAC immersion and duct temperature
Sanitary process temperature with clamp connection

Selection note

Immersion depth should be at least ten sheath diameters in liquid and more in gas. A 6 mm probe fitted into a 30 mm pocket will read the pocket wall, not the process, and the error grows as the pipe temperature diverges from the media temperature.
