EnOcean Wireless Door and Window Sensor

Know whether doors and windows are open or closed, in real time

Pressac’s wireless current sensors (CT) measure the alternating current (AC) and report the average of 5 measurements every 30 seconds.

The small, energy-harvesting devices use ultra-low power wireless and battery-less technology making them easy to install and very low maintenance. They simply clip around a cable and the wireless transmitter attaches outside the panel for reliable wireless data transmission. They can easily be fitted inside a machinery panel, distribution panel or other suitable location.
