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

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.
