LiftMaster 50-HERK-RC2 Programming Remote
The LiftMaster 50-HERK-RC2 is a handheld programming tool for the 50-HERK2 microwave motion detector. It gives a technician ground-level access to sensor settings that would otherwise require repeated ladder work, cover removal, and manual adjustment at the sensor.
The remote is used to tune how the motion detector sees vehicle and pedestrian traffic near a commercial door. Correct setup can reduce unwanted openings from cross traffic, improve vehicle approach detection, and help the door close properly after a vehicle leaves the detection area.
Compatible With
Use with LiftMaster 50-HERK2 motion detectors and related Herkules/Hercules 2 style sensor programming applications when supported.
- LiftMaster 50-HERK2 commercial motion detector
- 50-HERK2 microwave motion sensor applications
- Commercial sectional door motion detection setup
- Rolling steel door motion detection setup when using compatible LiftMaster motion sensor wiring
- Warehouse, loading dock, service bay, and industrial door applications using 50-HERK2
- Herkules / Hercules 2 sensor family references when matched to the correct programming remote
Compatibility note: This is a sensor programming remote, not a door operator remote control, receiver, or access transmitter.

Technician Note
Use the remote during sensor commissioning, then walk-test and vehicle-test the opening. The final settings should match the actual traffic pattern, mounting height, door speed, and customer workflow.
Before Ordering Checklist
- Confirm the sensor is a LiftMaster 50-HERK2 or compatible Herkules/Hercules-style sensor.
- Do not order this as a garage door opener handheld remote.
- Verify the sensor is powered and in programming mode when required.
- Document the final settings after commissioning.
- Test pedestrian, vehicle, and cross-traffic behavior before leaving the job.
Professional Advisory
Motion detector settings affect when a commercial door opens and closes. A qualified commercial door technician should tune the sensor so it does not create nuisance openings, missed vehicle detection, or unsafe door movement around pedestrians and equipment.
Product Questions and Answers
What does the 50-HERK-RC2 do?
It is a programming remote used to configure the LiftMaster 50-HERK2 commercial motion detector.
Is this a garage door opener remote?
No. It does not operate a residential opener. It is used to program and fine-tune the motion detector sensor.
What settings can it adjust?
It can be used for detection field setup, mounting height, relay hold interval, cross-traffic optimization, direction recognition, people/vehicle separation, and other supported sensor functions.
Does the remote need to be wired to the operator?
No. The remote communicates with the compatible motion detector for programming and does not wire into the door operator.
Where is this remote commonly used?
It is commonly used on commercial door openings such as warehouses, loading docks, service bays, and industrial doors using a 50-HERK2 motion detector.
