85239-1 Speed Pickup Sensor Unit

Feature & Principle

It adopts variable reluctance magnetic induction principle. When the gear tooth passes the sensor head, magnetic flux changes and generates AC sine wave signal. The signal is transmitted to speed controller for speed calculation, overspeed alarm and closed-loop speed regulation. No external power supply is required.
