The HEIDENHAIN ERA 4880 is an exposed modular angle encoder without integral bearing for measuring steps 0.005° to 0.0005° with 1Vpp output and an 80µm grading period.

The HEIDENHAIN ERA 4880 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 4880 offers the following features…

• Incremental 1Vpp signals
• Accuracy of ±3”
• 80µm grating period
• Hub inside diameters of Ø 40mm, Ø 80mm, Ø 120mm, Ø 180mm and Ø 270mm
• Mechanical permissible speeds of 40 000 rpm, 25 000 rpm, 18 000 rpm and 13 000 rpm
