Pro-Range E38S6G5-600Z-G24N Rotary Incremental Encoder - 38mm, Photoelectric, ABZ 3 Channels, 600 PPR

The encoder provides a three-channel incremental output with open-collector signals. Channels A and B produce quadrature square waves 90 degrees out of phase for determining direction and counting pulses, while the Z channel outputs a single index pulse per revolution for establishing a reference position. External pull-up resistors to your logic voltage (e.g., 5V or 3.3V) are required for proper signal reading.

The encoder operates on a wide 5 to 24V DC supply. While the supply voltage is 5-24V, the open-collector outputs can be pulled up to a different voltage, such as 3.3V, allowing direct interface with 3.3V logic microcontrollers like ESP32 or STM32. You must connect external pull-up resistors from each output line (A, B, Z) to your microcontroller's 3.3V rail.

The encoder features a compact 38mm diameter housing designed for PCB or bracket mounting. The specified 38mm PCB hole diameter is for the main body. You will need a compatible shaft coupling to connect it to your motor or rotating assembly. Ensure the mounting surface is rigid and aligned to prevent axial or radial loads that could affect accuracy or lifespan.

The encoder is rated for operation at speeds between 3000 and 6000 RPM. Exceeding the maximum rated speed may lead to signal degradation or mechanical failure. For high-speed applications, ensure your controller's input capture or interrupt routine can process the pulse frequency, which at 6000 RPM and 600 PPR equates to 60 kHz.
