OrangeRX 600 PPR ABZ 3-Phase Incremental Magnetic Rotary Encoder - IP54, 2m Cable

This encoder provides 600 Pulses Per Revolution (PPR) on each of its A and B channels. Because the A and B signals are in quadrature (90 degrees out of phase), a standard decoder can count 4 state changes per pulse cycle, resulting in 2400 Counts Per Revolution (CPR). The Z channel provides one index pulse per revolution for absolute reference.

Connect the Red wire to your logic supply voltage (typically 5V or 12V, check datasheet), and the Black wire to ground. The White (A), Green (B), and Yellow (Z) wires are open-collector outputs. Each must be connected to your input pin via a pull-up resistor (4.7kΩ included) to the same logic voltage. The golden shield/drain wire should be grounded at the controller end for EMI protection.

Pull-up resistors are required because the encoder uses open-collector outputs. They pull the signal line to a defined high logic level when the encoder's internal transistor is off, ensuring clean digital signals and protecting the output stage from damage. The package includes four 4.7kΩ resistors, one for each phase (A, B, Z) and a spare.

The Z phase produces a single pulse per full revolution of the shaft. It serves as an index or reference mark, allowing your system to establish an absolute zero position within each rotation. This is crucial for homing sequences, multi-turn position tracking when used with a counter, and synchronizing multiple axes.

With an IP54 protection rating, the encoder is protected against limited dust ingress and water splashes from any direction. It is suitable for most industrial floors and machinery environments but is not submersible or designed for high-pressure washdown (IP65/IP67). For harsher conditions, a higher IP-rated model should be selected.
