Part No.


Supervises an integrated reed contact and reports every status change immediately.

An energy-harvesting wireless magnet contact sensor for EnOcean systems. Powered by a solar cell, the sensor works absolutely maintenance-free. An integrated energy store allows operation for several days in total darkness. In dark surroundings, a coin cell battery can be retrofitted.


With a small housing the sensor can easily be mounted to windows or door frames or at cabinets using the included double-sided adhesive pad. The ultra-slim magnet has a preassembled adhesive pad.


The EMCSA supervises an integrated reed contact and reports every status change immediately (open < > closed). In addition a sign of life signal is sent at regular intervals. The device provides the option to use enhanced security mode with encrypted communication.
