Web Information

The Model 21000 photoelectric speed sensor is used with IRD balancing instruments to detect the rotating speed of a part. This speed sensor operates on a retro-reflective principle and requires reflective tape to be attached to the rotor.
The optical system is coaxial and minimizes problems associated with ambient light. For best performance, the sensing axis of the photocell should be placed at a slight angle from perpendicular to the reflective tape. An indicator light on the side of the sensor tells when the sensor is being triggered by the tape.


Pre-owned. Good physical condition.
