Wireless Dry Contact Sensor – Switch & Contact Closure Monitoring

The ALTA® Wireless Dry Contact Sensor is a versatile solution for detecting open or closed states between two contact points. It can be connected to external mechanical switches, buttons, relays, or contact plates—making it perfect for monitoring doors, gates, alarms, and machinery status.

This sensor uses bare-wire cable terminations for flexible integration and is available in two standard cable lengths: 0.3 m (1') and 0.9 m (3'). When a contact state changes, the sensor sends a wireless signal to your gateway, enabling real-time monitoring and alerts from virtually anywhere.

⚠️ Note: Requires a compatible Monnit gateway and may require software. Visit our Gateway & Software section or explore pre-configured kits for setup.
