Encoder RE40

Ø 40 mm – metal housing

The small size encoders series RE40 feature great accuracy, compact size and stoutness.

The incremental encoder RE40 can be supplied with different mechanical flanges: the type RE40 has 6 fixing holes on diameter 30 mm, while the encoder E40V has a front fixing screw, and the series RE40Q is provided with a square flange of mm 43×43. The types RE40M and RE40S are hollow shaft encoders designed for motor coupling, respectively by joint and by anti-rotational elastic metal support. For all the types the ppr no. ranges from 2 to 12500, with or without zero pulse (RE40 or RE41).

The aluminium housing, with axial or radial cable gland, grants IP65 protection degree against environmental agents.
