Encoder E40

Ø 40 mm

The small size encoders series E40 feature great accuracy and compact size.

The incremental encoder E40 can be supplied with different mechanical flanges: the type E40 has 6 fixing holes on diameter 30 mm, while the type 40A has 4 holes on diameter 25.4 mm; the encoder E40V has a front fixing screw, and the series E40Q is provided with a square flange of mm 43×43. The types E40M and E40S 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 (E40 or E41).

The series standard case is out of ABS plastics, with axial or radial cable or connector outlet; series RE40 with aluminium housing and IP65 radial cablepress outlet is also available.
