Wireless Single-Input Dry Contact Sensors

Lose contact? Know instantly.

ALTA^® Wireless Single-Input Dry Contact Sensors detect if contact is made or broken between two wired points.

These sensors remotely monitor production line operation, track when a forklift's seat is occupied, or alert you if a gate is left open. They can monitor any equipment or system with mechanical switches, relays, transistor switches, or contact plates. Power over Ethernet, intrinsically safe IECEX-certified, and wireless sensor types support small to medium, enterprise, and industrial firms.

How Dry Contact Sensors Work

Within 15 minutes, the sensors can be mounted and wired to endpoints. Then, you can get alerts via email, text, or call if contact is broken (indicating that the points are no longer touching) or if they make contact when they shouldn't.

Retrofit one of the sensors below and bring new life and intelligence to equipment and machines. Start remotely monitoring product volume, mechanical actuation, equipment use, and physical access security today. For example, the sensors can monitor a line valve opening or closing, a backup generator powering up, and a fluctuating propane tank level.

WARNING: Use caution when interfacing with ALTA Dry Contact Sensors. Any external AC or DC voltages WILL DAMAGE the wireless sensor's electronics. Monnit is not responsible for troubleshooting, replacing, or reimbursing damages incurred by disregarding this warning.
