Industrial Wireless Dry Contact Sensor – Contact Closure Detection

The Wireless Dry Contact Sensor is designed to detect the presence or absence of contact between two wired points. Ideal for monitoring mechanical switches, relays, door contacts, and custom triggers, this sensor enables real-time event detection and alerting for safety, security, or automation.

Featuring bare-wire cable terminations and available in 0.3 m (1') or 0.9 m (3') cable lengths, this sensor integrates easily into existing systems. When a contact opens or closes, the sensor transmits a wireless update, making it perfect for door monitoring, alarm triggers, or remote equipment status.

⚠️ Note: Requires a Monnit gateway and may require software. See our Gateway & Software page or explore complete kits for setup.
