STM320U

Magnet Contact Transmitter

Enocean

The radio transmitter module family STM 320 from EnOcean enables the implementation of a wireless magnet contact sensor. Powered by a small pre-installed solar cell, it works absolutely maintenance-free. An integrated energy store allows operation for several days even in total darkness. The STM 320 supervises an integrated reed con-tact and reports every status change immediately (open<>closed). In addition a sign of life signal is transmitted every 20-30 minutes. Key applications are window and door sensors.
