Dunkermotoren RE22 Incremental Encoder

The Dunkermotoren RE22 is a compact magnetic incremental encoder designed to mount directly to Dunkermotoren BG and GR brushless DC motors, adding quadrature position feedback to motor platforms that would otherwise run open-loop. It operates contact-free with no wear, delivering 256 pulses per channel (1,024 counts per revolution) at a 60 kHz cutoff frequency — sufficient for accurate speed and position control across the operating range of compatible motors.

The RE22 is compatible with the GR 30, GR 30S, BGA 22 dCore, BG 32 dCore, BG 32 KI and BG 42 dCore motor series, and can be mounted open to the motor body or with a protective hood for applications requiring IP54 or higher. It powers from 5 Vdc and communicates over a two-channel A/B interface. The mating connector 27573.40235 is available with a 500 mm pre-wired strand. Standard protection class is IP 30.

Typical applications include conveyor and material handling systems, laboratory and medical automation, pump and valve actuators, and general-purpose motion control where closed-loop speed or position feedback is required.

The RE22 pairs with the full Dunkermotoren motion system — combine with a GR-series planetary gearbox for torque multiplication, or add a Dunkermotoren electromagnetic brake for controlled stopping and position holding.
