ASM Sensors Inc., Elmhurst, IL, offers its POSIMAG Model PMIS4 position sensor and corresponding Model PMIR4 magnetic wheel as an alternative to optical encoders for rotating applications. The combination is a contact-free measuring system that serves as a reliable incremental position system that resists dust, shavings, and many liquids commonly found in industrial environments. The magnetic wheel's plastic-bound magnetic material is magnetized in defined distances. The wheel is available with an optional index mark which produces an index pulse signal, once/rev. Output pulses are available with either decade, binary, or angle divisions.
