Lebanon, N.H.  June 15, 2004.   Manufacturing engineers at a leading steel plant are using a large-bore magnetic encoder with large, heavy duty motors to provide high resolution, speed and position sensing in the extreme heat and harsh environment of the mill.  The new magnetic encoders more than doubled the operating life of the optical encoders they replaced, according to the magnetic encoder designer and manufacturer, Admotec Inc. of Lebanon, N.H.

The large-bore magnetic encoder, a custom version of Admotec’s K Series, incorporates an insert-molded large bore magnetic encoder wheel and magnetoresistive chip sensor, designed to the demanding specifications of the application.  The encoder produces resolution up to 7200 cpr with a large (up to 2 mm) wheel/sensor gap.  Available with wheels from 10 mm (1/2 in) to 250 mm (10 in), K Series magnetic encoders offer a virtually unlimited choice of wheel size and resolution.  Custom encoders can also be designed for special requirements. 

The large-bore magnetic K Series encoders are used in steel, paper and textile mill applications as well as in harsh industrial environments including shock, vibration, sawdust, oil, grease, salt spray and excessive moisture.
