Dunkermotoren ME52 Magnetic Pulse Generator
The Dunkermotoren ME 52 is a magnetic pulse generator that works contact-free and wear-free using Hall sensors and a magnetic ring. It provides 2 ppr or 12 ppr (8 or 48 cpr) depending on version, with open collector plus pull-up output and two square-wave signals 90° phase shifted. The ME 52 is compatible with the GR 42, GR 53, GR 63 and BG 62 d...
Read MoreThe Dunkermotoren ME 52 is a magnetic pulse generator that works contact-free and wear-free using Hall sensors and a magnetic ring. It provides 2 ppr or 12 ppr (8 or 48 cpr) depending on version, with open collector plus pull-up output and two square-wave signals 90° phase shifted. The ME 52 is compatible with the GR 42, GR 53, GR 63 and BG 62 dCore motor series.
Supply voltage ranges from 5 Vdc to 26.5 Vdc, with a minimum of 7.5 Vdc required below 0°C. The ME 52 RR variant meets the requirements of EN 50155 for railway rolling stock. Protective hoods in IP 54 or higher are available on request.

Features
- Hall-sensor and magnetic-ring sensing runs contact-free, so there are no wear surfaces to service on high-cycle machinery
- Choose 2 ppr or 12 ppr (8 or 48 cpr) to match the feedback resolution to the axis instead of over-specifying the controller
- Two square-wave channels 90° apart resolve direction as well as speed, so reversing loads are tracked correctly
- Open collector with pull-up already fitted connects straight to controller inputs — no external resistor network to add
- 5–26.5 Vdc supply spans common 12 V and 24 V control rails, with a 7.5 Vdc minimum below 0°C for cold-start installations
- ME 52 RR variant meets EN 50155, opening the same feedback design up to railway rolling-stock projects
