Contact Configuration (Guard Closed State)
SI-LS83LA18D SI-LS83LA18E
Contacts: Open Closed Transition
Switching Diagram tolerances:
Operating point ± 3.5 °
Operating torque ± 10%
Guard closed (home position) is at 0° when mounted in a positive
mode. Not to scale.
Maximum allowable travel varies by model and is listed at bottom of
switching diagram (minus operating tolerance). Switching Angles (θ)
are measured with actuating system in vertical position (as drawn) and
are applicable both left and right movement.
Installation must ensure sufficient travel for positive opening of safety
contacts and account for any mechanical tolerances.
Actuating system can be removed and reposition/rotated by 90°
increments. Ensure all screws are properly re-installed.

NOTE: This symbol
for a positive-opening safety contact (IEC 60947-5-1) is used in the switching
diagram to identify the point in actuator travel where the normally-closed safety contact is fully open.
