ROUNDSS Machine Tool Spindle Encoder is an optical rotary spindle motor sensor.The spindle encoder is mainly applied to the spindle of the CNC machine. The synchronous pulse of the encoder is processed by the CNC and the calculated tool data is transmitted to the servo motor for execution.

Absolute encoder's working principle is similar to incremental encoder. Inside the absolute encoder, there is a rotary disc with many transparent holes on it. Light receiver will collect the interval light. The light signal will be converted to pulse signal through circuit manipulation. ROUNDSS as China the 2nd largest encoder supplier, supplies a complete series of single-turn and multi-turn absolute encoder products from 25mm to 206mm products you can customized and choose.

Roundss rotary shaft encoder as an incremental rotary encoder provides cyclical outputs (only) when the encoder is rotated. The incremental rotary encoder is the most widely used of all rotary encoders due to its low cost and ability to provide signals that can be easily interpreted to provide motion related information such as position and velocity.
