Photocell Safety Beams DFN
Surface or Semi Flush mount Safety Beam Set - 12 or 24 volt
The set consists of a transmitter and receiver creating an invisible safety beam that when broken will prevent your gates closing. Power is usually taken from the gate control panel and this can be 12v or 24v AC or DC
The photograph shows the DFN with the surface back box in place and also removed for semi flush mounting.
The receiver has both a normally open and a normally closed connection so an additional set can be used to trigger the gate opening if you wish.
