AMM31 New Generation Kit Encoder

Lika Electronic USA


AMM31 is the first of a new series of optical kit encoders developed by Lika Electronic. It excels because of its large through hollow shaft, simple mounting, and a wide selection of incremental and absolute interface options.

AMM31 is frameless and has a very compact, lightweight and bearingless design. The external diameter is shrunk down in size to 31 mm/1.22” and the through hollow shaft is enlarged up to 10 mm/0.394”.

It can be equipped with a broad choice of both incremental and absolute interfaces, they are:

  • incremental AB0 /AB0 signals, 65,536 PPR
  • 1Vpp Sine/Cosine signals for speed feedback
  • UVW commutation signals, up to 32 pole pairs for BLDC motor control
  • SSI serial interface
  • BiSS serial interface
  • SPI serial interface

Absolute versions can be singleturn and multiturn. Singleturn resolution is up to 23 bits, revolutions are 65,536.

It has very wide mounting tolerances that allow for the simplest and fastest installation. It does not need any configuration software. AMM31 is ideally suited for direct integration into motors, robotic joints, surgical and diagnostic robots, confined-space, and weight-sensitive applications.
