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.
| Feature / Specification | Details |
|---|---|
| Manufacturer | LiftMaster / Chamberlain Group |
| Product Type | APS encoder with harness |
| Part Number | K76-34697-3 |
| Voltage | 12V |
| Application | Slide gate position feedback and travel learning |
| Compatible Operator Type | DC slide gate operator |

| Notes | Model and harness specific |
If the operator has travel-learning faults, inspect the harness first. A rubbed, pinched, corroded, or unplugged harness can mimic encoder failure.
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.
