FAQ
Q: What are the advantages compared with incremental encoders?
A: Absolute encoders do not require reference points and are resistant to power failure/vibration interference, making them particularly suitable for safety-critical applications.
Q: Can the original encoder of an old actuator be replaced?
A: We provide shaft bushing adapters and protocol converters, and more than 90% of models can be directly replaced.
