Retooling and setup processes to change formats or position objects on machines and manufacturing systems with numerous axes in automation technology are often still conducted by handwheel. In such cases, electronic handwheels make workpiece setup easier. Despite its compact dimensions, the new HR 1120 electronic handwheel from HEIDENHAIN is robust, making it suitable both for portable and for stationary housings. The mechanical detent with 100 positions per revolution permits very precise and exact control of movement. The electrical signal output at TTL levels with differential signals as per RS422 allows connection to many standard programmable logic controllers and PC slot cards.
