  • Highly miniaturized: 5 x 6 x 0.8 mm
  • Outputs A quad B
  • Robust against oil grease, liquids, dust, particles
  • Programmable resolution and max speed
  • Optional with holder, cable and connector

The ID4501C incremental encoder kit consists of an encoder and a codewheel. The encoder is an integrated circuit in a PCB housing. It provides incremental A and B output signals in quadrature. The codewheel is a PCB with passive copper strips.

The resolution and the maximum speed of the encoder are user-programmable or can be programmed ex-factory.
