SAI25A

Solid-shaft Incremental Encoder

The SAI25A is widely used as a sensor for automatic control, automatic measurement, and measurement of angle and speed. Its small size, light weight and excellent performance make it suitable for small space applications.

Up to 1200 Pulses High-resolution incremental feedback
Compact Size Designed for small space applications
Excellent Performance Suitable for control and measurement systems

Compact Design for Precision Measurement

SAI25A is a compact solid-shaft incremental encoder designed for automatic control, automatic measurement, and angle and speed measurement applications.

With a 25mm outer diameter and 4mm solid shaft, the encoder is suitable for applications where installation space is limited. It supports resolutions up to 1200 pulses and offers customizable resolution options.
