Wireless magnetic contact sensor for using with a remote control and door bells in the Nexa system series. With a magnetic sensor you can create an entry alarm that is activated when a door or window is opened.

When the two parts of the magnetic sensor are separated, a wireless "on" signal is sent to the connected receiver such as a remote switch which then turns on the light or sounds the doorbell. When the sensor is intact again, an "off" signal is sent that turns off the light, immediately or with a time delay of 1, 5 or 10 minutes. You can also reverse the function where the off signal is sent when it is separated and an on signal when closed.

The Nexa MEST-1701 magnetic sensor can be mounted with screws or double sided adhesive tape and can be attached both horizontally and vertically. Compatible with all Nexa self-learning receivers and wireless doorbells but is not suitable for using with a dimmer switch.
