Control Potentiometer/Position Sensor Supplies Full Endless Rotation

The N-15 control potentiometer/position sensor uses an FR4 pc-board substrate that allows the device to be customized without incurring a significant tooling charge. The ability to print and hold tight tolerances on resistive curves on the backside of the board provides flexibility to de-sign the N-15 as a combination switch and rheostat. This low-profile (4.4-mm), customizable potentiometer/position sensor also features full endless rotation (360°). It offers a wide electrical angle of 340°±10° and an extended operating-temperature range of −40°C to 120°C. Available in SMD or through-hole mounting, the device is standard with a polarized "T" rotor that lets shafts be inserted from either side of the product. With a catalog-specified mechanical life of 100,000 cycles, the N-15 offers reflow- and wave-soldering capabilities. Options include laser trimming, parts with detents, special mechanical angles, and custom geared rotors to increase the electrical angle to over 360°. The N-15 costs $0.68 each, with a production lead time of six to eight weeks.
