New Feature: If the power always keeps on, the single-turn encoder can be used as an electronic multi-turn encoder (but this function does not have the power-off memory feature), the total turns can be counted up to one million turns or more. Now that it has the measuring speed function, which is easy for users to calculate. When it is used as a single turn absolute encoder, any position within the measuring range is unique, even if there is interference or movement after power break, the position information will not be lost.

Wiring Connection
Communicate Protocol | RS485 （Modbus RTU) |
Red wire | Power Supply |
Black wire | GND |
Yellow wire | Z0 |
Green wire | 485B |
White wire | 485A |
- Please pay attention to the voltage value (5V, 24V) on the encoder label before power on. Make sure to supply power accordingly.
- Set zero position: connect yellow wire to ground (black wire) more than 100mS.
- Please do not connect the yellow wire to anywhere during working except when it is needs to be set zero position.
- Restore the factory setting function: after power off, connect the yellow wire to ground (the black wire). Powered on again, it can be reset after 2 minutes, and separate the two wires after reset.
Software Interface
We provide RS485 host computer software, which is convenient for you to test directly on the PC.
