Liftmaster K80-19011, TRACTION RING, HALL EFFECT WHEEL
The LiftMaster K80-19011 traction ring is the hall effect wheel ring used to support accurate motion sensing in select commercial gate operators. Hall effect feedback systems depend on the correct wheel or ring passing the sensor consistently. When the ring is worn, loose, cracked, contaminated, or missing, the operator may lose reliable feedback and show travel, limit, or movement-related symptoms. This part is most clearly associated with the HS670GL slide gate operator family, but it should be matched by the original parts breakdown before ordering.

Common Compatible Models
- LiftMaster HS670GL slide gate operators
- Select LiftMaster commercial slide gate operators where K80-19011 / 80-19011 is specified for the hall effect wheel assembly
Important Compatibility Notes
Confirm the hall effect wheel, sensor location, and parts diagram before ordering. A similar ring from another operator may not track correctly.

Technician Note
When replacing the traction ring, inspect the hall effect sensor, wheel alignment, debris buildup, and wiring. A damaged sensor or poor alignment can cause similar symptoms even with a new ring.
Before Ordering Checklist
- Confirm the operator model and parts diagram call for K80-19011.
- Inspect the existing ring for cracks, glazing, wear, or looseness.
- Check the hall effect sensor position and wiring condition.
- Do not substitute a different wheel or ring unless the part number matches.
Professional Advisory
Gate movement and sensing repairs should be tested only after the gate path is clear and safety devices are working. Do not bypass monitored entrapment protection to force operation.
Product Questions and Answers
What does K80-19011 do?
It acts as the traction ring for the hall effect wheel used in motion feedback on select commercial slide gate operators.
Which model is it commonly used with?
It is commonly referenced with LiftMaster HS670GL slide gate operators.
Can a worn traction ring cause travel errors?
Yes. If the hall effect system cannot read movement properly, the operator may show travel or motion feedback issues.
Should the sensor be replaced at the same time?
Only if testing shows the sensor, wiring, or alignment is faulty. Inspect those items during service.
Is 80-19011 a related number?
Yes. 80-19011 is commonly listed as a related reference for K80-19011.
