The HC20 encoder from Dynapar (Gurnee, IL), for brushless servo and step motor applications, is capable of up to 2,500 pulses per revolution, and is available with commutation tracks for 4, 6, or 8-pole variants of brushless motors. The encoder has direct-read non-interpolated technology that stems from a custom phased array ASIC.

With industry-standard 50mm diameter and short 36mm mounting depth, the encoder is suited for use on NEMA 23 and 34 size brushless servo and stepper motors. It is available with 6mm or 8mm hollow or hub shafts, or a 9mm shaft with 10:1 taper. Two tether options are also offered, in 40mm and 55mm bolt circles.

The motor is available with a wide 5 to 26 VDC operating range.
