Wireless Open-Closed Sensor – Door & Window Magnetic Monitoring

The ALTA® Wireless Open-Closed Sensor is a reliable and easy-to-deploy solution for detecting when a door, window, or access point is opened or closed. Using a magnetic switch, the sensor monitors changes in position and instantly transmits alerts, helping to improve security, automate workflows, and monitor access across a wide range of environments.

This sensor operates with a magnetic detection gap of up to 19 mm (0.75 in.) and includes a 381 mm (15") cable with pre-terminated magnetic switch leads. It’s ideal for use in offices, warehouses, server rooms, retail spaces, or anywhere access needs to be tracked wirelessly.
