    Overview

    Factory direct sales SUCH miniature optical incremental encoders. These encoders feature a stainless steel shaft and metal housing, are compact with a housing diameter of 38mm and a shaft diameter of 8mm, and are easy to install. The 400ppr compact rotary incremental encoder has selectable voltages of +5VDC/+8~30VDC, side cable output, selectable cable lengths of 1m/2m/3m/4m, and 6 output modes.

    Feature

    • Modular design for easy installation and accurate output pulses.
    • The compact structure of the miniature optical incremental encoder makes it suitable for automated equipment with limited installation space.
    • The incremental rotary encoder uses a dedicated ASIC chip for stable and reliable signal processing.
    • The robust and durable overall structure, along with the stainless steel shaft, is suitable for long-term, high-frequency operation in industrial settings.

    FAQ
    ❯

    A miniature optical incremental encoder is a compact position sensor that uses light and an encoder disk to generate pulses as the shaft rotates. It can provide relative position and speed feedback.

    ❯

    400 PPR (pulses per revolution) means that the encoder outputs 400 electrical pulses per 360° of shaft rotation. Higher PPR values ​​provide finer motion resolution.

    ❯

    Each pulse represents a rotation angle of 360° / 400 = 0.9°. Using quadrature decoding (x4 mode), the effective step size can reach 1600 counts per revolution.
