Power-Supply Versions
Select the version to match the door-controller supply. The 5 V and 24 V versions are not interchangeable by assumption.
Four-Wire Connection Functions
Confirm the actual connector marking and controller wiring before energizing.
Before Ordering
- Match the ACVF encoder housing, mounting holes and motor arrangement.
- Confirm the required 5 V or 24 V supply version; do not substitute one voltage version for the other.
- Match the connector and channel wiring to the controller circuit. Do not infer pin order from wire colour alone.
- Isolate the door drive before replacement, then check the feedback direction and operation using the applicable service procedure.
Frequently Asked Questions
What type of feedback does it provide?
The encoder provides A and B pulse channels for door-motor feedback.
Can a 5 V encoder be used on a 24 V supply?
No. Select the voltage version that matches the controller supply and encoder marking.
What does the C-shaped housing do?
It provides the open mounting form used around the corresponding door-motor shaft arrangement. Check the physical fit and fixing points before ordering.
What should be checked when replacing it?
Check supply voltage, connector, signal-channel wiring, mounting-hole positions and the motor-side installation. Isolate power before service.
