Honeywell's RV4NAYSD503D is a 2W conductive plastic potentiometer designed for various industrial and commercial applications. It converts rotary motion into a change of resistance, providing a smooth transition of voltage or current levels. Available in resistances from 100 Ohm to 5 MOhm, and with linear, log, and antilog tapers, this potentiometer offers flexibility in output signal profiles. It is suitable for audio and visual equipment, foot pedal controls, machine controls, and welding equipment, among other applications. The RV4 series meets MIL-R-94 requirements and is not RoHS compliant.
