Dunkermotoren MG2 Magnetic Pulse Generator

The Dunkermotoren MG2 is a magnetic pulse generator that works contact-free and wear-free using Hall sensors and a magnetic ring, providing two square-wave signals with 90° phase shift for speed and direction sensing. Resolution depends on motor pairing: 2 ppr (8 cpr) on the G 30 and hooded GR 42 builds, or 12 ppr (48 cpr) on the open GR 42 build. The MG 2 is compatible with the GR 30, GR 30S and GR 42 motor series.

Output is open collector on the G 30 and hooded GR 42 builds, and open collector with pull-up on the GR 42. The supply range is 3.9–24 Vdc. Protective hoods in IP 54 or higher are available on request.

Typical applications include conveyor and material handling systems, general-purpose motion control, and basic speed and direction feedback wherever a full incremental encoder is not required.

The MG2 pairs with the Dunkermotoren GR 30 and GR 42 geared motor series it is designed to mount to, adding contact-free speed and direction feedback without changing the motor’s footprint.
