The PDB183-GTR31-504A2 is a 17 mm guitar potentiometer with integrated DPDT push-pull switch, featuring a knurled shaft with 18 teeth and long bushing configuration. It offers a resistance value of 500 kO with ±20% tolerance and supports both linear and audio taper options. The potentiometer operates over a temperature range of -10°C to +50°C, with a power rating of 0.2 W (linear) or 0.1 W (audio) and maximum operating voltages of 200 V (linear) or 150 V (audio). Key mechanical specifications include a 300° ± 5° mechanical angle, rotational torque of 30 to 100 g-cm, and rotational life of 15,000 cycles. The integrated DPDT switch provides 0.3 A @ 30 VDC resistive load capacity with 15,000 cycle switch life and 4.3 ± 0.2 mm switch travel. This potentiometer is ideal for professional audio equipment, guitar amplifiers, and other pro audio applications requiring reliable volume and tone control with integrated switching functionality.
