Dunkermotoren RE30 Series Incremental Encoder

The Dunkermotoren RE30 incremental encoder series provides contact-free quadrature position feedback for the GR 30, GR 30S, GR 42, GR 53, GR 63, GR 80, BG 32 dCore, BG 32 KI, BG 42 dCore, BG 45, BG 62 dCore, BG 65, BG 66, BG 75, and BG 95 dPro motor series — the widest motor compatibility of any encoder in the Dunkermotoren range.

The standard RE30 delivers 100 or 500 ppr via an A/B/I interface and is rated from −40°C to +100°C, making it suitable for demanding ambient conditions. Where cable runs exceed 2.5 m between encoder and control, the RE30 TI adds an integrated line driver with complementary outputs (/A, /B, /I) to reject electrical noise, and extends resolution to 1,024 ppr across its three configurations. Both variants mount open at IP 30, with a protective hood at IP 54, or integrated into the BG 65 motor profile housing at IP 65.

The RE30 series is well suited to industrial automation, conveyor and material handling systems, medical and laboratory equipment, and pump or valve drives. The index pulse makes both variants particularly effective in applications requiring repeatable homing — automated assembly, CNC axes, and multi-axis positioning systems where an external homing switch would add complexity and cost. The RE30 TI is the preferred choice where long wiring runs between the motor and control cabinet are the norm, or where electrical noise is a concern.

As part of the broader Dunkermotoren motion system, the RE30 series pairs with GR-series planetary gearboxes for torque multiplication and with Dunkermotoren electromagnetic brakes for controlled stopping and position holding.
