Encoder RE620

63.5×63.5 mm square flange

The range of square-flanged incremental encoders includes the series RE620, with centering mask diameter 31.75 mm, compatible with the international standard SIZE25, and the series RE650, with centering mask diameter 50 mm.

Both the types are housed in a metal case. The connection type and position can be chosen among different options, as well as the output signal formats and the shaft diameters.

The pulses per revolution number ranges from 2 to 12500.
The zero reference pulse option is available for both series (type RE621 – RE651).
