The ERM incremental modular rotary encoders consist of a magnetized circumferential scale drum and a scanning unit with magnetoresistive sensor. These encoders are available for diameters 80mm, 70mm, 80mm, 120mm, 130mm, 180mm, 220mm, 295mm, and 410mm:
Typical applications include machines and systems with large hollow-shaft diameters where protection from dust and splashwater is required.
