The BI-38-H8-2500-PU Absolute Rotary Encoder is a compact, high-precision rotary feedback device designed for industrial automation and motion control systems. It delivers accurate position and speed information for CNC machines, robotics, conveyors, and printing equipment.
This encoder provides absolute rotary position reference after system initialization, ensuring consistent and repeatable positioning during machine operation. Featuring a 38 mm compact body, 8 mm solid shaft, and 2500 PPR resolution, it is ideal for applications requiring reliable feedback in limited installation spaces.
The push-pull (HTL) output guarantees strong, noise-resistant signals even in electrically noisy environments. With a wide 524V DC operating voltage, this absolute rotary encoder integrates seamlessly with PLCs, drives, and industrial controllers.

Q1: Is this a true absolute rotary encoder?
This encoder provides absolute position information after system reference or homing. It is not a battery-backed true absolute encoder.
Q2: Why is it called an absolute rotary encoder?
In many industrial systems, incremental encoders are used as absolute rotary position devices after initialization.
Q3: What is the resolution of this encoder?
It has a resolution of 2500 pulses per revolution (PPR).
Q4: What output signal does it use?
It uses a Push-Pull (HTL) output, suitable for long cable lengths and noisy environments.
Q5: Can it be used with PLCs and CNC systems?
Yes, it is fully compatible with PLCs, CNC controllers, and industrial drives.
