Liftmaster K76-34697-3, APS ENCODER WITH HARNESS, 12V
The LiftMaster K76-34697-3 is a 12V APS encoder with harness used for operator position feedback on select RSL12 slide gate systems. The encoder tells the control board where the gate is during movement, helping the operator learn limits and manage travel. The included harness is important because damaged wiring or poor connections can cause the same type of problems as a failed sensor.
This part is especially important on DC slide gate operators that depend on electronic position feedback rather than older mechanical limit assemblies. Correct fitment depends on voltage, connector style, harness routing, and operator generation.

Technician Note
If the operator has travel-learning faults, inspect the harness first. A rubbed, pinched, corroded, or unplugged harness can mimic encoder failure.
Before Ordering
- Confirm the model is RSL12U, RSL12UL, or an approved RSL12 variant
- Match the 12V encoder requirement
- Compare the old harness and connector
- Check for fault codes and wiring damage before replacement
Professional Advisory
Position-sensing faults can cause unexpected gate movement or failed limit setup. If the operator will not learn travel correctly after repair, have the system inspected by a qualified gate technician.
Important Ordering Warnings
- Not interchangeable with 24V APS encoder assemblies
- Do not force connectors or modify the harness to fit another operator
