See Section 8.1.3 for additional limit switch data.
SG92_H/I02, I09
OPEN
CLOSED
Factory adjustment:
Active faces of proximity switches are covered when actuator is in intermediate position.
Active face A (upper switch) becomes free at open limit of travel and face K (lower switch) at closed limit.
Function can be inverted on site by re-adjusting the cam discs.
Sensing distance 2...4 mm, depending on type of switch
Supply voltage 8 V DC (Ri 1 kΩ)
Current consumption
active face free, > 3 mA
active f ace covered, < 1 mA
