Description
Reviews (0)

Netvox wireless 2-Input dry contact sensors - R718J2 can be used to detect contact between two wired contact points. This sensor can be used with an external mechanical switch or a contact plate to alert the user via APP when the contacts touch or a switch is triggered

Principle of Operation

The device can be connected to dry contact devices, such as various switches, buttons, and output of the reed switch. It can detect the closing or disconnecting signal of the dry contact. It uses the SX1276 wireless communication module.

Example Applications

Tamper switches
Barn door access monitoring
Freezer / cooler door access
Freezer / cooler doors (to determine if they are not closed all the way
Convenience store cooler doors (to determine if they are not closed all the way)
Forklift seat switches
Dry contact sensor
