Frequently Asked Questions

What is an optical rotary encoder?

An optical rotary encoder is a sensor that converts the angular position or motion of a shaft into digital or analog output signals using a light source and photodetector.

What's the difference between absolute and incremental encoders?

Absolute encoders provide a unique position value at all times, even after power loss. Incremental encoders output pulses relative to movement and require a reference point.

Can you customize encoder specifications?

Yes, we offer customization in resolution, shaft type, housing, output signal, and protection level based on your application needs.

What industries use your encoders?

Our encoders are used in robotics, CNC machines, elevators, medical devices, wind power, textile machinery, and industrial automation.
