This product is composed of accuracy components, so please be careful not to drop it2. When installing, if the eccentricity or deviation angle is too large, it will shorten its service life3. Do not use in strong impact, vibration, corrosive, large magnetic field, high temperature, high humidity and acid‑base environment4. An error in the number of pulses may be caused when the power is turned on or off. After the power is turned on, there is a 0.5S delay time for use.5. After the product is fixed, do not pull the cable with a force exceeding 29.4N6. When there is a high‑voltage line or power line nearby, please use a conduit to cover the cable7. When wiring, pay attention not to short‑circuit the terminals, and make sure that the wiring is correct. Wrong wiring will damage the internal circuit. It is recommended to insulate the unconnected terminals.8. Shielded wire should be grounded9. Do not disassemble the product by yourself10.
