Capacitive proximity sensors CM

  • Even functions reliable in harsh industrial environments, which reduces machine maintenance costs and downtimes.
  • Quick and easy adjustment can be made via the potentiometer or teach button to save valuable time during commissioning.
  • Highly flexible range of applications thanks to compact housing and universal mounting systems.
  • High shock and vibration resistance and minimal sensitivity to dust and moisture ensure reliable object detection and reduce machine maintenance costs.
  • Optical adjustment indicator ensures reliable object detection to minimize potential machine failures.


Capacitive proximity sensors can detect all powdery, granulated, liquid, and solid materials – even through plastic or glass walls.

SICK’s capacitive proximity sensors feature extremely high electromagnetic compatibility (EMC), which prevents false switches and sensor failure.
