Liftmaster K1D8247 Hall Effect Sensor Board use on CSW200U Swing Gate Operators
The LiftMaster K1D8247 hall effect sensor board is a board-style movement feedback component used on select CSW200U swing gate operators. It helps the control system read gate movement or position feedback, which is important for proper travel monitoring and operator response.
This part is typically considered when the operator has hall effect sensor faults, inconsistent movement feedback, or diagnostic behavior that points to the sensor board. Before replacing it, the technician should inspect the harness, connector pins, sensor mounting, control board input, and mechanical drive components. A sensor fault can be caused by wiring or mechanical problems, not only by the board.
K1D8247 is commonly tied to CSW200U and related CSW200UL references. It should not be mixed with hall effect sensor kits used on slide gate operators or older SW420 applications.

Technician Note
Do not assume a board-style sensor failure until wiring, connectors, target condition, operator drive condition, and board inputs have been inspected. A loose harness can create the same symptoms as a failed sensor board.
Before Ordering Checklist
- Confirm the operator model is CSW200U or verified CSW200UL
- Match the original board number to K1D8247
- Compare connector layout before ordering
- Inspect harness and sensor mounting area
- Do not substitute K74-style sensor kits
Professional Advisory
CSW swing gate operators use high-force moving hardware. If the gate is binding, moving unpredictably, or showing safety faults, have a qualified gate technician diagnose the system before replacing electronic parts.
Important Ordering Warnings
- K1D8247 is not interchangeable with K74-G0589 or K74-18381
- Older CSW200 generations may use different sensor or control parts
Product Questions and Answers
