Dunkermotoren RE56 Series High-Resolution Incremental Encoder
The Dunkermotoren RE56 and RE56TI are high-resolution incremental encoders that deliver quadrature position and speed feedback for closed-loop motion control. With up to 2,000 pulses per channel and 8,000 counts per revolution, they give control systems the resolution needed to hold precise shaft positions, detect direction of rotation, and maintain smooth velocity at low speeds — tasks where lower-resolution encoders fall short. Both encoders mount directly to Dunkermotoren brushless DC and geared motors, sharing the motor housing without additional brackets or couplings. The RE56TI variant adds complementary differential outputs (/A, /B, /I) for noise-immune signal transmission — the recommended choice for cable runs beyond 2.5 m between encoder and controller, or installations in electrically noisy environments. Typical applications include robotics and collaborative automation, conveyor and material handling systems, pump and valve control, and precision positioning in industrial machinery. The standard RE56 is rated to −40°C to +100°C, making it suitable for cold-store and process environments without a specialist build. The RE 56 series is designed for use with the Dunkermotoren GR42, GR53, GR 63, and GR 80 geared motor series and the BG62 dCore, BG65 dCore, and BG75 dCore brushless EC motors.
