RK09L1120A2S is a 9mm metal shaft snap-in rotary potentiometer designed for single-unit horizontal mounting applications. This potentiometer features a 10 kO total resistance with 15A resistance taper, a metal shaft with 15 mm length, and operates without center detent. The device is rated for a maximum operating voltage of 50V AC or 10V DC, with a total rotational angle of 300 ± 5°, rotational torque of 2 to 25 mN·m, and an operating life of 15,000 cycles across a temperature range of -10°C to +70°C. The potentiometer is commonly used in audio equipment, consumer electronics, and industrial control applications where reliable variable resistance adjustment is required.
