Allen-Bradley RV20N Speed Control Variable Potentiometer

The Allen-Bradley RV20N Speed Control Variable Potentiometer is a panel-mount rotary potentiometer with a carbon-film element, designed for manual adjustment of analog speed references in motor control systems and VFD circuits. It covers a resistance range from 500 Ω to 2 MΩ, a 0.25 W power rating, and ±20% tolerance, with 290° mechanical rotation (±10°) and 245° electrical rotation (±10°), plus a 6 mm shaft and 20 mm body diameter. Electrical specs include a maximum contact resistance of 3 Ω and insulation resistance of at least 100 MΩ at 500 VDC, with operating temperature from -10°C to +85°C and RoHS compliance; typical uses include variable frequency drives, DC motor speed controllers, HVAC systems, industrial fans, conveyors, mixers, and other equipment requiring adjustable speed references.
