Dunkermotoren ME52 Magnetic Pulse Generator

The Dunkermotoren ME52 gives a controller reliable speed and direction feedback from a geared motor without adding a wear point. It reads position through a magnetic ring and Hall sensors rather than an optical disc, so there are no contacting or light-sensitive parts to abrade, clog or fail — the kind of ruggedness that matters on high-cycle, dusty or dirty machinery where an optical encoder would struggle.

Two quadrature output channels resolve both how fast the shaft turns and which way, and the pull-up resistor built into the open-collector output lets it wire straight into standard PLC and drive inputs with no external resistor network to design in. A wide supply window lets the same generator drop into 12 V or 24 V control systems, and it mounts directly to Dunkermotoren’s GR-series geared motors so feedback is integrated into the drive rather than bolted on separately.

That suits it to conveyor and materials-handling lines, pump and valve actuators, and general motion-control tasks that need dependable feedback in demanding conditions. For rolling stock and trackside equipment, the ME52 RR version is certified to EN 50155, bringing the same feedback approach to railway projects.

As part of the wider Dunkermotoren motion system, the ME52 can be specified alongside the BG brushless DC motors and GR planetary gearboxes it’s designed around — so drive, gearing and feedback are ordered and integrated as one package.
