NB-IoT Dry Contact Sensor for Remote Open/Close Monitoring

The NB-IoT Dry Contact Sensor offers reliable and intelligent monitoring of open/close states for any dry contact input, such as gates, access panels, doors, relays, and valves. Once triggered, it transmits real-time status data to your IoT server over NB-IoT cellular networks, using protocols such as MQTT, TCP, UDP, or CoAP.

Designed for low-power operation and outdoor deployment, it features a weatherproof enclosure and a built-in 8500mAh industrial-grade battery that supports up to 5 years of autonomous operation*. The unit also tracks open durations, event counts, and includes a configurable Open Alarm function to alert users if contacts remain open too long.

Whether you're in smart agriculture, utilities, industrial automation, or security, this sensor offers reliable visibility into your infrastructure—anywhere, anytime.
