Heidenhain 639953-08 is a graduation drum from the ERA 180 series for modular angle encoders without integral bearings. Its optical graduation comprises 9,000 lines on a precision-machined steel cylinder with a nominal diameter of 180 mm. Combined with a compatible scanning head, the system produces a 1 Vpp sinusoidal analogue signal from a 63 μm graduation. The stated angular accuracy is ±3.0 arcseconds, supporting demanding position measurement in machine tools, machining centres, swivel tables and rotary tables. The associated measuring system uses a DC 5 V ±10 % supply. The drum outside diameter is approximately 250 mm. One analogue reference mark provides a reproducible zero position for each revolution. The permitted operating-temperature range is -10 °C to +80 °C. Without an additional protective cover, the assembly carries an IP 20 rating. The 639953-08 is supplied as the individual graduation-drum component for an existing ERA 180 measuring system and can be used for replacement or extension where the mechanical and signal interfaces match. The item is listed as used and originates from industrial stock. Available directly from our warehouse in Germany.
