The Heidenhain 639420-14 is an optical scanning head in the ERA 4880 series for bearingless incremental modular angle encoders. It is intended for contact-free angular-position measurement in machine tools, machining centres, torque motors and rotary tables. The 639420-14 uses the photoelectric principle to scan the associated ERA-4880 scale drum with an 80 µm grating period. Its analogue 1 Vpp output can be interpolated by suitable Heidenhain signal-processing electronics or a compatible CNC control. The modular design covers an encoder-drum diameter range from 100 mm to almost unlimited dimensions, allowing it to be integrated into different axis designs. A cut-off frequency of ≥350 kHz (−3 dB) supports signal transmission at high axis speeds. Electrical supply is 5 V DC ±10 %, with a maximum current consumption of 100 mA. The integrated 1-m connecting cable terminates in a 12-pin M23 coupling. With an original Heidenhain cable, the permitted cable length is up to 150 m, which supports installations with remotely located control cabinets. This 639420-14 is offered as a new item in its original packaging and is available from our warehouse in Germany.
