ERA 4480 / 4480C (40µm)

Description

The HEIDENHAIN ERA 4480 modular rotary encoder consists of a solid steel scale drum, scanning unit and optional protective cover. The graduation is located on the circumference of the cylindrical scale drum and is scanned with reflected light, offering axial movements up to ±0.5 mm (± 0.02 in.) in the drive shaft, resulting therefore have no effect on measuring accuracy. The ERA 4480 offers the following features…

  • Incremental 1Vpp signals
  • Accuracy of ±3”
  • 40µm grating period
  • Hub inside diameters of Ø 40mm, Ø 80mm, Ø 120mm, and Ø 180mm
  • Outside diameters of Ø 80mm, Ø 130mm, Ø 180mm, Ø 250mm
  • Mechanical permissible speeds of 40 000 rpm, 25 000 rpm, 18 000 rpm and 13 000 rpm
