Milesight EM300-MCS | LoRaWAN Magnetic Contact Switch Sensor

The Milesight EM300-MCS is an industrial-grade LoRaWAN Magnetic Contact Switch engineered to provide real-time monitoring of entry points in critical infrastructure. Comprising a sensor main body and a magnetic part, it triggers an immediate wireless alert whenever a door, window, or cabinet is opened or closed. Housed in a robust IP67-rated enclosure, the EM300-MCS is not only a security tool but also a climate monitor, featuring integrated high-precision Sensirion sensors to track ambient temperature and humidity levels.

Reliable Security & Climate Intelligence

Proactive Alerting Instant LoRaWAN uplinks for every open/close event ensure security teams are notified immediately, with built-in data storage to prevent loss during network downtime. Sensirion High Precision Equipped with high-accuracy Sensirion chips, the sensor provides secondary value by tracking environmental stability and condensation risks in monitored areas.

Facility Monitoring Scenarios
