Overview

Our Bulletin 875 Capacitive Proximity Sensors have an adjustable sensing distance and are ideal for applications that can be challenging for other sensing technologies. Capacitive sensors can detect non-metal solids and liquids in addition to standard metal targets. They can even sense the presence of some targets through certain other materials, making them an ideal choice in those applications where other technologies cannot be used.

Available in cylindrical or miniature rectangular models, these sensors are resistant to humidity and dust and feature improved immunity to electromagnetic interference (EMI), especially that created by drives. Specific models are IO-Link enabled to help minimize downtime and increase productivity.
