Capacitive Switches

Capacitive Switches
The MS888X-series are proximity sensors that make use of a patent from EDISEN Sensor Systeme GmbH & CO KG. A change in capacitance is detected by a digital algorithm that is auto-calibrating such that all stray capacitances are compensated. This results in a reliable proximity switch.

 

Applications

  • Medical
  • Automotive
  • Buildings & Sanitary
  • Mobile application
  • Hermetical or vandal proof switches
  • Intrinsic safety
