What Is the Nexakey NX-SF310 Infrared Safety Beam?
The Nexakey NX-SF310 is an infrared through-beam photocell pair, made up of a transmitter and a receiver. It stops your boom barrier from closing on a vehicle or person in the lane. It gives the controller a simple relay NO/NC signal and works with every NEXA GATE barrier.
- Transmitter + receiver pair
- Relay output NO / NC
- Designed for the NEXA GATE barrier controller
- Weather-rated for outdoor lanes
How Does an Infrared Safety Beam Work on a Boom Barrier?
The transmitter sends an infrared beam to the receiver across the lane. When a car, motorbike, or person breaks the beam, the photocell sends a relay signal to the barrier controller. The controller then holds the arm up instead of driving it down.
Why Does a Boom Barrier Need a Photocell Safety Beam?
A boom that closes on a car, motorbike, or person is a liability before it is an inconvenience. A photocell pair costs little compared with the barrier, and it is the most useful safety accessory on any public lane. It also needs less maintenance than a light curtain and has a lower failure rate.
Can the NX-SF310 Work With Third-Party Controllers?
Yes. The relay NO/NC output connects to third-party controllers as well as the NEXA GATE barrier controller. This lets you add the NX-SF310 to an existing gate without replacing the control system.
Where Can You Install the NX-SF310 Photocell?
Install it on any lane where the arm must not drop on a vehicle or person:
- Public lanes: photocell protection is the baseline for any gate the public drives through
- Gated communities and staff gates: protects residents, guards, and management vehicles
- Factory and warehouse yards: stops the arm dropping between vehicles that queue close together
- Finished driveways and basement entrances: pairs with radar where cutting a ground loop is not acceptable
Which NEXA GATE Accessories Work With the NX-SF310?
The NX-SF310 handles photocell protection. Add the NX-VR310 vehicle detection radar where you cannot saw-cut a ground loop, because radar detects vehicles without cutting the road surface. You can also pair up to 50 remotes with one barrier. Decide during commissioning who holds each remote, and record it.
