IER22 Incremental Optical Encoder - Reflective

Features:

  • 2 channel quadrature outputs
  • Low cost
  • Small size (22mm)
  • Quick and easy assembly
  • 48, 64, 100, 128, 200, 256 cycles per revolution (CPR)
  • Fit shaft diameters: 2mm to 5 mm

Applications:

The IER provides motion detection at a low cost, making them ideal for high volume applications. Typical applications include vending machines and motor manufacturing applications.

Description:  

The IER is high performance, cost-effective, two­ channel optional incremental housed encoders. These encoders emphasize high reliability, high resolution and easy assembly. The IER encoders contain a reflective surface mount encoder chip (AEDR-8300) and a 48, 64, 100, 128, 200, 256-line count code wheel. The outputs of the IER encoders are two square waves in quadrature.
