Magnetic Incremental Encoder Relishes Rough Terrain

ASM introduces posirot PMIS4/PMIR7, a non-contact, wear-free magnetic incremental encoder designed to withstand harsh environmental conditions and offers a unique simple slide-on shaft assembly.


The measuring system posirot PMIS4/PMIR7 consists of a PMIS4 sensor head and a PMIR7 magnetic ring with magnetic index mark. The sensor head is made of a robust metal and is fully enclosed on all sides. The magnetic ring is available in three different diameters (27, 35 or 50 mm) to fit various shaft sizes. The magnetic ring is mounted directly onto a machine or motor shaft without a coupling utilizing a patented slide-on mounting solution.
