Heidenhain 533903-73 is the AK ERA 4480 scanning head for the ERA 4480 series of modular, bearingless incremental angle encoders. With 14,000 lines and a graduation period of 40,000 µm, it supplies high-resolution angular-position signals for demanding machine-tool applications. The analogue output signal is approximately 1 Vpp, and the documented cut-off frequency is 350 kHz. An analogue reference mark supplies a defined reference position within one revolution. The scanning head operates from a 5 V supply with a tolerance of ±10%. Its IP 40 rating complies with EN 60529, and the operating-temperature range is −10 to +80 °C. The electrical interface uses a 12-pin M23 coupling wired to Heidenhain connection assignment D549380. A 2.00 m PUR cable with a diameter of 3.7 mm provides installation flexibility inside the machine enclosure. A complete ERA 4480 measuring system consists of two separately supplied components: the graduation drum mounted on the drive shaft and the AK ERA 4480 scanning head. Typical applications include lathes, milling machines, machining centres, rotary tables and tilting axes. Before replacement, compare the complete 533903-73 identification, line count, graduation period, connector assignment, cable length and matching drum. This scanning head is available directly from our warehouse in Germany.
