Thru-Shaft Potentiometers 640 Series Datasheet640 Series Thru-Shaft Potentiometers Potentiometers convert rotary motion into a change of resistance, supplying a smooth transition of voltage or current levels. The resulting voltage output may be used to control position transducers in a wide variety of potential applications. The 640 Series Thru-Shaft Potentiometers are actuated by a customer-provided actuator shaft instead of by a shaft/ bushing integral to the sensor. The low-profile housing allows use where space is at a premium. All versions are sealed for dust. Splash-sealed or moisture-sealed options feature O-ring seals between the rotor and housing and cover and epoxy sealing between the leadwires, the housing and the cover. The 640 Series are available in resistances from 1 kOhm to 1 MOhm, inclusive. Tapers include linear and a 360 quadrature voltage to meet a wide range of application requirements. A dual-contact version allows for two mechanically-tracking electrical actions, or true 360 quadrature voltage output.
