Wireless contact sensor
Know when it opens.
Monitor a gate, garage door or roller shutter without running a sensor cable all the way to the receiver. OneSensor sends contact changes wirelessly to RX-Link or MotorGuard Pro+.

A wireless link for your sensors
Make an opening part of your security setup.
Reed switch & magnet
Use the built-in reed switch and magnet to detect when the fitted gate or door opens and closes.
External contact input
Connect a suitable NC / NO contact, such as a beam, switch or roller shutter contact, to send its state wirelessly.
Power options
Choose a battery version or a version powered from a 5–24 V DC supply. Indoor and outdoor enclosure options are available.
Choose the receiving device
Connect to RX-Link or MotorGuard Pro+.
Pair OneSensor directly with RX-Link to link contact events to an existing alarm-zone input. Pair it with MotorGuard Pro+ for gate monitoring and app-based alarm settings.
A gate left open
OneSensor detects the gate opening. With RX-Link’s delayed output selected by DIP switches, the receiver triggers the wired alarm connection if the gate remains open beyond the selected delay. Closing it before the delay expires cancels the delayed alarm.
When using MotorGuard Pro+ or FenceGuard, alarm delays are set in the OneControl app.

Installation matters.
The installer fits the sensor and magnet, pairs the receiver and tests the signal with the gate or door open and closed. Choose the enclosure and power option to suit the location.
Can OneSensor operate a gate motor on its own?
OneSensor sends sensor information. A compatible receiving device and the correct relay wiring are needed to operate or signal connected equipment.
Does it connect directly to the app?
OneSensor uses its wireless receiver connection. MotorGuard Pro+ provides app monitoring for the connected gate setup.
