The P231-QC15BR10K is a 24 mm rotary panel potentiometer designed for general-purpose variable resistance applications. It features a conductive plastic element with a resistance range of 500 ohms to 1 megohm, standard tolerance of ±20%, and a maximum input voltage of 500 Vac. The potentiometer offers a total mechanical travel of 300°±10° with an actual electrical travel of 260°, a rotational torque of 0.5 to 1.25 oz-in, and static stop strength of 70 oz-in. With 100,000 cycles of rotational life and an operating temperature range of -20°C to +70°C, this component is well-suited for industrial control panels, audio equipment, and instrumentation where reliable variable resistance adjustment is required.
