The YD69 rotation speed sensor from Shanghai Cezhen measures wheel and shaft speed with dual‑channel Hall output and forward/reverse detection.
The YD69 rotation speed sensor is designed for detecting wheel and shaft speed as well as linear velocity. It offers a wide frequency range from 0 Hz to 20 kHz and provides two output channels with a 90° phase shift to enable forward/reverse discrimination. The sensor is non‑contact, wear‑free, and features robust construction with IP68 sealing and strong vibration resistance.
The manual includes installation guidelines, wiring connections (brown + 24 V, black COM, blue OUT), technical specifications, and selection options for different mounting configurations. It also provides troubleshooting tips and customization possibilities for specific gear modules. This manual is written in Chinese.

It provides two output channels with a 90° phase difference; the channel that leads indicates the rotation direction.
The sensor is powered by +24 VDC, with an acceptable range from 5 V to 26 V.
The sensor can drive up to 20 mA per channel.
