Potentiometer 10KΩ Single-Turn Panel Mount — 6mm Shaft, Linear Taper, with Nut & Washer

Potentiometer — 10KΩ Single-Turn, Panel Mount / PCB Mount, 6mm Shaft

The 10KΩ single-turn panel mount potentiometer is the most widely used potentiometer value in electronics — the universal choice for Arduino analog input control knobs, voltage dividers, comparator thresholds, and general-purpose user controls. With a standard 6mm knurled shaft, smooth ~300° linear rotation, and dual panel/PCB mounting capability, this potentiometer is the default choice when you need a user-adjustable control in any circuit.

Supplied with mounting nut and washer for panel installation. The 6mm shaft accepts all standard potentiometer knobs available worldwide — from simple plastic caps to precision aluminum knobs for professional instrument panels.

Mounting Options

• Panel mount: Insert shaft through a 7mm (9/32″) hole in the enclosure panel. Secure with the supplied washer and 10mm nut. Solder wires to the three pins. Add any standard 6mm-shaft knob for user control.
• PCB mount: Solder directly to PCB using the 5.08mm (0.2″) lead spacing — compatible with standard 0.1″ perfboard hole spacing. Note: leads are not long enough for solderless breadboards.
• Anti-rotation tab: A locator tab on the body prevents rotation in enclosures with a matching slot. Can be snapped off with pliers if not needed.
• Screwdriver adjust: If recessed behind a panel on a PCB, the slotted/knurled shaft can be adjusted with a flat-head screwdriver without a knob.

Why 10KΩ is the Universal Potentiometer Value

10KΩ is the default potentiometer value because it balances two competing requirements: low enough to drive most circuit inputs without loading effects, and high enough to limit current draw to a negligible level. At 10KΩ, a voltage divider from 5V draws only 0.5mA — negligible for any power supply, yet low enough impedance to drive op-amp inputs, comparators, and ADC inputs without error. It is the value specified in the vast majority of Arduino tutorials, electronics textbooks, and reference designs worldwide.

Typical Applications

• Arduino analog input control knob — the standard potentiometer for analogRead() tutorials and projects
• Comparator threshold setting — LM393, LM339: set switching voltage with a 10K voltage divider
• Op-amp gain and offset control — LM358, TL071: adjustable gain in amplifier circuits
• NE555 / TLC555 timing control — adjust oscillator frequency or monostable pulse width
• Bench power supply voltage adjust — user-facing output voltage control knob
• DIY synthesizer and audio effect controls — cutoff frequency, resonance, envelope time
• Sensor sensitivity adjustment — LDR, NTC thermistor, and pressure sensor threshold setting
• Function generator amplitude and frequency control
