Description

BEI Motion Systems MX213-25-1024U Rotary Optical Encoder with Cable

The BEI Motion Systems MX213-25-1024U is a rotary incremental optical encoder producing 1024 pulses per revolution (PPR). It uses an optical disk-and-detector assembly inside a compact disc-shaped housing to convert shaft rotation into digital quadrature output signals. The unit ships with its original multicolor ribbon cable and multi-pin connector attached.

Specifications & What's Included

  • Manufacturer: BEI Motion Systems Company, Computer Products Division, San Marcos, CA

Applications

Rotary optical encoders like the BEI MX213 series are used in motion control and automation systems to provide precise angular position and velocity feedback to a controller. They are commonly found in CNC machines, robotics, servo drive systems, medical equipment, semiconductor handling equipment, and industrial automation platforms. The 1024 PPR resolution makes this encoder well suited for applications requiring moderate-to-high position accuracy. BEI Motion Systems (later absorbed into Sensata Technologies) was a leading US manufacturer of optical encoders from the 1980s through the 2000s, and MX-series encoders from this era are still encountered in legacy motion control installations and replacement/repair applications. The hollow-bore design allows the encoder to be mounted directly over a shaft, simplifying installation in tight spaces.

Condition: Used
This BEI Motion Systems MX213-25-1024U rotary optical encoder has been inspected and appears to be in good used condition. It was pulled from a working system where it was previously in service. The housing is intact with normal wear consistent with industrial use. The multicolor ribbon cable and multi-pin connector are attached and appear undamaged. Please view our photo set and contact us if you have any questions.
