Rotary Encoders Transducers Product EN FIAMA US

FIAMA EN Series encoders are hollow shaft encoders that turn a rotating motion into a digital pulse signal i.e. line driver output.  The EN encoder uses the same mounting configuration and is similar profile to many of FIAMA’s OP position indicators.  Easily installed by inserting the hollow bore over the shafted axis being monitored, and securing the rotating bore to the shaft via a set screw.  3D DRAWING AVAILABLE UPON REQUEST.


  • EN14: hollow shaft with Ø14mm bore.
  • EN20: hollow shaft with Ø20mm bore.
  • EN25: hollow shaft with Ø25mm bore.

Encoder resolution (pulses/revolution): 10 – 50 – 60 – 90 – 100 – 200 – 250 – 500
