Liftmaster K74-G0589 Hall Effect Sensor Kit 74-G0589 Slide Gate Operators
The LiftMaster K74-G0589 hall effect sensor kit is used in select commercial slide gate operators to provide movement feedback from the drive system to the operator control board. In gate operator service, this type of sensor is commonly used to report rotational movement, speed, or position information so the control system can monitor travel and respond to abnormal conditions.
When a hall effect sensor circuit fails or loses its reference, the operator may show movement-related diagnostic errors, stop unexpectedly, fail to read motion correctly, or behave as though the motor is not moving even when mechanical components are turning. The sensor should be inspected along with wiring, magnets or targets, control board inputs, and mechanical drive components.
This kit is most often associated with LiftMaster SL590, SL595, SL595GL, and HS670 slide gate operators. Since slide gate operators vary by generation and control system, the model number and parts diagram should be checked before ordering.

Technician Note
Hall effect sensor faults are not always caused by the sensor itself. Check harness condition, board input, target/magnet condition, motor movement, and mechanical drive condition before replacing parts.
Before Ordering Checklist
- Confirm the operator model number and generation
- Match the parts diagram to K74-G0589 or 74-G0589
- Inspect the harness and connector before ordering
- Confirm the operator is a compatible slide gate model
- Do not confuse this kit with SW420 or CSW hall effect parts
Professional Advisory
Gate operators contain moving parts and high-force drive systems. If the gate moves unexpectedly, binds, or has active entrapment protection faults, have a qualified gate technician diagnose the system.
Important Ordering Warnings
- K74-G0589 is for select slide gate applications and should not be substituted for K74-18381 or K1D8247
- Sensor issues may also involve the control board or wiring harness
Product Questions and Answers
What does the K74-G0589 hall effect sensor do?
It provides movement, RPM, or position feedback so the gate operator control system can monitor drive operation.
Which operators commonly use K74-G0589?
Common references include LiftMaster SL590, SL595, SL595GL, and HS670 slide gate operators.
Is K74-G0589 the same as 74-G0589?
Yes, 74-G0589 is commonly listed as a related number for the K74-G0589 hall effect sensor kit.
Can this sensor fix a gate that stops during travel?
It may help if the sensor or sensor circuit is the cause, but wiring, board inputs, drive components, limits, and gate binding should also be checked.
Is this used on CSW200U swing gate operators?
No. CSW200U applications commonly reference a different hall effect sensor board, such as K1D8247.
