K17PM(K Series)

This is the "M Series", which is equipped with a battery-less absolute encoder that achieves a slim design with our unique sensor mechanism on a hybrid type stepping motor.

By applying the time measurement mechanism of an analog clock, our absolute encoder can maintain the current position even when not powered, without the need for a backup power source. Furthermore, it is possible to resume operation without returning to the origin even after restart, contributing to the reduction of tact time while reducing the need for origin sensors and limit sensors required for returning to the origin.

The position detection method can be chosen from absolute output and incremental output, and the size is available in 9 types with different L dimensions of □28mm / □42mm / □56.4mm.
