What Is a 50mm Encoder?

A 50mm encoder is a rotary sensing device with a housing diameter of approximately 50 millimeters. It converts rotational movement into electrical signals that can be interpreted by control systems.

These encoders are commonly installed on:

  • Electric motors
  • Conveyor rollers
  • CNC machines
  • Packaging equipment
  • Robotics systems

The compact size makes them suitable for applications where space efficiency and precision are equally important.


How a Rotary Encoder Works

A rotary encoder detects shaft movement and converts it into digital or analog signals. These signals help automation systems determine:

  • Position
  • Rotation direction
  • Speed
  • Angular displacement
