BEI Sensors 01002-7573 Incremental Optical Encoder

BEI Sensors 01002-7573 is an H25 incremental optical encoder. It converts rotary motion into a pulsed electrical signal that enables measurement of relative position and motion in feedback control systems. The part number 01002-7573 identifies this specific unit within BEI Sensors’ line of incremental encoders. Incremental optical encoders like this one provide relative position information starting from a known reference, making them well-suited for real-time speed and position feedback in automation, robotics, CNC machinery, and other motor-control applications that rely on precise timing of rotational movement. Because this encoder uses optical sensing, rotation is detected via pulses generated as light passes through a coded wheel or pattern and is read by a detector, delivering a fast, non-contact signaling method. In typical installations, the encoder’s output is fed to a motion controller or drive to synchronize motor speed with the demanded position, enabling accurate motion profiles and repeatable operation.
