Encoder SEB/SEB-Z

Ø 50 mm

Stout and reliable the incremental rotary encoders series SEB/SEB-Z can be employed in severe conditions. They can be supplied in the bidirectional type (SEB) or bidirectional with zero reference pulse (SEB-Z). The number of pulses per revolution ranges from 2 to 12500.

The types SEB-M/SEBZ-M operate according to the magnetic principle, with a number of ppr ranging from 8 to 2048.

The ABS plastic case offers high protection against environmental agents – IP65 degree, which can be upgraded to IP66 with the optional O-ring mounted on the encoder shaft.

The connections are provided by cable or connector in axial position; the output signals can feature the NPN open collector, push-pull or line-driver format.
