WH148 Potentiometer 15mm Shaft 500 Ohm

The WH148 Potentiometer 15mm Shaft 500 Ohm is a single-turn rotary potentiometer with a 500 Ω track, three terminals and a 15 mm shaft for fitting a knob. The WH148 is a common rotary pot for adjustment knobs on control panels and boards, and the low 500 Ω value suits low-impedance circuits, voltage dividers and small adjustment jobs where a higher-value pot would be too high.

WH148 Potentiometer 15mm Shaft 500 Ohm Specifications

• Model: WH148 rotary potentiometer

• Shaft length: 15 mm
• Terminals: 3 (two track ends and the wiper in the middle)
• Type: single turn, single gang

WH148 Potentiometer 15mm Shaft 500 Ohm Applications

• Analog input controls for Arduino and ESP32
• Setting reference voltages and thresholds
• Adjusting brightness in low-voltage LED circuits
• Calibration and trim controls in low-impedance circuits
• Electronics education and prototyping

What's in the Box

• 1 × WH148 500 Ω potentiometer with 15 mm shaft

Tip: For an Arduino, connect the outer pins to 5 V and GND and the middle pin to an analog input such as A0. At 5 V a 500 Ω pot draws 10 mA, so choose a 10 kΩ pot if you only need a simple position reading with lower current.
