Product Description

The Potentiometer Knob 113 is engineered for a comfortable, non-slip user experience. The "Buffer" refers to the extended base flange that sits flush against the control panel, protecting the internal shaft and mounting hardware from dust and accidental impact. The interior is designed to grip the splines of standard 6mm shafts firmly, preventing "slippage" during fast rotations. Its robust plastic construction ensures electrical insulation, making it safe for use in high-voltage power supply projects or sensitive audio amplifiers.

Key Features

Ergonomic Ribbed Grip: Features a textured surface to allow for precise micro-adjustments even with gloved hands.
Panel-Flush Buffer: The integrated skirt masks the mounting hole and hardware, providing a premium finished look to custom projects.
Clear Orientation Mark: Includes a contrasting pointer line, allowing the user to identify the current setting at a quick glance.
Universal Fit: Standard 6mm internal diameter makes it compatible with almost all WH148 and similar rotary potentiometers.
Heat Resistant: Made from durable materials that withstand the typical operating temperatures of power electronics.

Technical Details

Internal Depth: Optimized to ensure the knob does not rub against the panel surface while maintaining a low profile.
Color: Classic Black body with a white indicator line for high contrast.
Weight: Lightweight design to minimize mechanical load on the potentiometer shaft.

Prototyping and Engineering Tips from Robogears

Shaft Alignment: Before pushing the knob onto the shaft, turn the potentiometer fully counter-clockwise to its "zero" position. Align the knob's pointer line with your panel's "Zero" or "Min" mark before firmly pressing it down.
Tight Fit Fix: If the knob is too tight to push on, do not use a hammer. Use a small flat-head screwdriver to slightly widen the gap in the potentiometer's split shaft. If the knob is too loose, gently squeeze the two halves of the split shaft together.
Cleaning the Buffer: The area under the buffer skirt can collect dust over time. When building a device for a workshop environment, a tiny drop of non-conductive silicone grease on the shaft can prevent dust from migrating into the potentiometer's internal resistive element.
Consistency: For a professional multi-knob interface (like a 3-channel power supply), always use the same model of knob. Mixing different styles of knobs can make the interface feel "cheap" and harder to navigate by touch.

Package Includes

1 x Potentiometer Knob 113 with Buffer

Disclaimer

Ensure the potentiometer is securely mounted to the panel with its own nut and washer before attaching the knob. Excessive force when installing the knob can damage the internal mechanism of the potentiometer.
