Use a free, downloadable app with these switches to automate alarms in your facility, such as sounding a buzzer if a trailer door is opened after a certain time.

These switches actuate when a magnet comes within sensing distance, and reset when the magnet moves away.

Mounted to your circuit board, these switches trigger when magnetic components get near, and reset as they move away.

Send signals in response to changing magnetic fields to trigger processes or monitor position, speed, and current.

Arm and disarm these alarms with a key.
