The 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. 80um grading period.

Axial movements up to ± 0.5 mm (± 0.02 in.) in the drive shaft therefore have no effect on measuring accuracy. The ERA 4480C permits shaft speeds up to 10 000 rpm. It is often mounted directly on high-speed ballscrews and spindles.

Incremental signals - 1 VPP
Accuracy - to ± 3`
Hub inside diameter - Ų 40mm / Ų 70mm / Ų 80mm / Ų 120mm / Ų 150mm / Ų 180mm / Ų 270mm
