Safety sensors
4 types of photocells can be connected to the safety control unit:
S5-5-X-X-SG-ST2: Type 2 safety photocell emitting infrared beams.
S5-5-X-X-SG-ST4: Type 4 safety photocell emitting infrared beams.
SL5-5-X-X-SG-ST4: Type 4 safety photocell emitting long-distance red laser beam.
S300-5-X-X-ST4: Type 4 safety photocell for long-distance applications.
See section 10 “Order data” for further details about available photocell models.
Using the above photocells independently from SG-BWS-T4 does not meet EN
61496-1 and CLC/TS 61496-2 requirements and is thus not allowed.
Connection of Type 2 photocells results in the whole system category downgrade
to Type 2.
S5 and SL5 sensors are housed in plastic tube casings featuring M18x1 thread.
