Lose contact? Know instantly.
Monnit Dry Contact Sensors detect if contact is made or broken between two wired points. This sensor remotely monitors production line operation, tracks when a forklift’s seat is occupied, or alerts you if a gate was left open.
These sensors can be quickly mounted and wired to two endpoints (such as existing switches or contact plates). Be alerted via email, text, or call if a contact is broken (indicating that the points are no longer touching) or if the two points make contact when they shouldn’t be.
This sensor comes standard with two replaceable AA batteries. The typical battery life is approximately 10 years.
WARNING: Use caution when interfacing with Dry Contact Sensors. Any external AC or DC Voltages WILL DAMAGE the electronics of the wireless sensor. Monnit is not responsible for troubleshooting, replacing, or reimbursing damages incurred by disregarding this warning
