SG 15

The SG 15 series is especially designed as a safety device for doors and gates. The system is approved by TÜV to be an E-device according to EN 12453, allowing it to be a stand-alone safety device on a power operated door or gate. 

The SG 15 light curtain system consists of a self-contained transmitter, SGT and receiver, SGR, which are to be positioned opposite of each other. The detectors are housed in compact, but sturdy, aluminium profiles, available in two different designs. 

The system is supplied with a 12-30 V dc power supply. The SGR includes a 5 wire, solid state relay output. Both the SGT and SGR include a test input which are activated simultaneously for system test purposes. The advanced automatic signal-tracking (AST) feature ensures that no onsite set up or adjustments are required. The signal of each individual channel is adjusted automatically, which compensates for misalignment and contamination during operation. Transmitter and receiver units are optically synchronised. 

The SG 15 series features the Dynamic Sequential Blanking Function which allows the detectors to be positioned in the guide tracks of an industrial door, where the door travels directly in front of the protection area, interrupting the beams sequentially from top to bottom. The special feature ensures that the system can distinguish between the closing door and an object by ignoring the beams that are obstructed by the moving door whilst leaving the below remaining beams active to detect an object below the door edge. 

Both the transmitter and receiver units are protected against reverse polarity of power supplies, control input and output signals. The output is also protected against short circuit and inductive loads.
All products include a 3-year worldwide warranty.
