Potentiometer 1KΩ Single-Turn Panel Mount — 6mm Shaft, Linear Taper, with Nut & Washer

Potentiometer — 1KΩ Single-Turn, Panel Mount / PCB Mount, 6mm Shaft

A 1KΩ linear taper single-turn potentiometer with a standard 6mm knurled shaft — designed for both panel mounting through an enclosure and direct PCB soldering. Supplied with mounting nut and washer for panel installation. The 1KΩ value is the preferred choice for low-impedance audio volume controls, motor speed controllers, and current-sense voltage dividers where a lower resistance is needed to drive the circuit without loading effects.

The smooth ~300° rotation with good linearity makes this potentiometer suitable for user-facing controls in DIY instruments, bench power supplies, and audio equipment. The 6mm shaft accepts all standard potentiometer knobs available worldwide.

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.

1KΩ vs Other Values — When to Choose 1K

• 1KΩ (this): Low-impedance circuits — motor speed control (PWM input voltage divider), low-impedance audio sources, current-sense reference voltage, LED brightness in low-resistance driver circuits
• 5KΩ: General-purpose audio and signal circuits, op-amp feedback networks
• 10KΩ: Most common value — Arduino analog input, comparator threshold, general-purpose voltage divider
• 100KΩ: High-impedance circuits — JFET bias, electret microphone, oscillator frequency control

Typical Applications

• DC motor speed control (PWM duty cycle voltage divider)
• Bench power supply output voltage adjustment (low-impedance reference)
• Audio amplifier volume control for low-impedance sources
• LED driver brightness control
• DIY instrument panel control (function generator amplitude, oscilloscope trigger level)
• Arduino analog input manual control knob
• Fan speed controller voltage reference
