Netvox R311CA – Wireless Dry Contact Sensor
Netvox wireless dry contact sensors can be used to detect contact between two wired contact points.
It can realize wireless alarm and other functions through built-in wireless module, and is compatible with
LoRaWAN protocol.
It can be easily networked with other related devices. The R311CA is durable and ensures optimum use and is a low
power consumption device. Due to their small size, they can be installed anywhere, they are wireless, so they take up
very little space.
