Potentiometer Plus Switch Stand Up To Harsh Environs

Capable of performing under severe environmental conditions, the PA 400 potentiometer with built-in switch is sealed with transfer-molded epoxy resin and an O-ring shaft seal. This is said to render the component impervious to high temperatures, corrosion, and moisture. With a rotation-life expectancy of 25,000 cycles, suitable applications include medical, food processing, automotive, and marine devices. A basic configuration consists of a 10.01-mm cube with gold contacts. A wide variety of bushings, cases and flat or rounded shafts are available. Users also have a choice of eight standard electrical tapers. Constructed of non-magnetic materials, the pot/switch combo is wave solderable. WILBRECHT ELECTRONICS INC., St. Paul, MN.
