Pro-Range 3806-OPTI-600-AB-OC 600 PPR 2-Phase Incremental Optical Rotary Encoder with 1.5m Cable

This encoder provides 600 Pulses Per Revolution (PPR), meaning it outputs 600 complete cycles on its A or B channel per shaft rotation. Because it generates a quadrature (AB) output, a decoder can count the rising and falling edges of both channels, resulting in 2400 Counts Per Revolution (CPR). CPR offers higher resolution for precise position tracking.

Connect the Red wire to your 5V or 3.3V supply (staying within the 5-24V range), Black to GND, and White (A) and Green (B) to digital interrupt pins (e.g., pins 2 and 3). You must install the included 4.7kΩ pull-up resistors between the A/B outputs and your logic voltage (VCC) to ensure clean signal levels and protect the open-collector outputs. The provided sample code uses hardware interrupts for accurate counting.

IP52 indicates the encoder housing is protected against limited dust ingress (IP5X) and dripping water when tilted up to 15 degrees (IPX2). It is suitable for indoor industrial environments with light dust and occasional condensation but is not waterproof for washdown or submerged applications. Ensure cable glands or connectors are properly sealed for the installed orientation.

Yes, the cable can be extended. To maintain signal integrity, use a shielded cable with a foil jacket and drain wire or a braided shield. Solder the shield (Golden wire) to a solid ground point at the controller end only to prevent ground loops. For high-EMI environments, a combination of individually shielded pairs within an overall braided shield is recommended.

The D-shaped (flatted) shaft provides positive mechanical coupling to a mating hub or coupling, preventing slippage under high torque or reversing loads. Mount the encoder body using the provided M3 screws, ensuring it is aligned and secure. Use a compatible coupling that matches the 6mm diameter and flat to transfer shaft rotation accurately without introducing axial or radial load.
