Wireless Dry Contact Sensors & Interface Meters

Dive deeper into operations with turnkey sensors

Monnit ALTA® Wireless Dry Contact Sensors and Interface Meters detect insights about equipment power status, door access, turnstile actuations, machinery, facility and factory automation, production lines, or mechanical systems and barriers. You set what thresholds the sensors should observe; if something goes wrong, alerts are sent by email, text, or voice call to authorized personnel. We also offer Power over Ethernet (PoE) and Wi-Fi Dry Contact Sensors.

How do these sensors improve operations?

They integrate with nearly any button, switch, system, or industrial and scientific device to collect data, including voltage, actuations, revolutions, or open/close counts. Sensor data paints a picture of equipment and system performance or facility use.

Monnit Sensors can be installed and configured within 15 minutes.
