The HEIDENHAIN ERA 4280 is an exposed modular angle encoder without integral bearing for measuring steps 0.005° to 0.0005° with 1Vpp output and a 20µm grading period.

The HEIDENHAIN ERA 4280 modular rotary encoder consists of a solid steel scale drum, scanning unit and optional protective cover with a graduation located on the circumference of the cylindrical scale drum offering axial movements up to ± 0.5mm (± 0.02 in.) in the drive shaft, resulting therefore with no effect on measuring accuracy. The ERA 4280C offers the following features…

• Incremental 1Vpp output signal
• Permissible shaft speed up to 10,000rpm.
• Mounted directly on high-speed ball screws and spindles
• Accuracy of ±3”
• Hub inside diameters of Ø40mm, Ø70mm, Ø80mm, Ø120mm, Ø150mm, Ø180mm and Ø270mm
