HR 1120 Electronic Handwheel
Electronic handwheels facilitate workpiece setup on positioning units and in automation applications. Despite its compact dimensions, the HR 1120 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 the motion. The electrical output at TTL levels with differential signals as per RS 422 allows connection to many standard programmable logic controllers (PLC) and PC slot cards. Controls from HEIDENHAIN use handwheels with expanded interface functions, which is why the HR 1120 cannot be connected to them.
