The 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.
Axial movements up to ± 0.5 mm (± 0.02 in.) in the drive shaft therefore have no effect on measuring accuracy. The ERA 180 permits shaft speeds up to 40 000 rpm. It is often mounted directly on high-speed ballscrews and spindles.
Incremental signals - 1 VPP
Accuracy - to ± 3`
Hub inside diameter - Ø 40 mm / Ø 80 mm / Ø 120 mm / Ø 180 mm*
Outside diameter - Ø 80 mm / Ø 130 mm / Ø 180 mm / Ø 250 mm
Mech. permissible speed - 40 000 rpm / 25 000 rpm / 18 000 rpm / 13 000 rpm
* ERA 180: on request up to 512 mm dia. and ± 2` accuracy
