Restore peak performance to your appliance with the VR B100K Water Heater Dimmer Control. This specialized 100KΩ linear potentiometer is designed for heavy-duty household and industrial applications, serving as a critical component for managing power levels in electric water heaters and dimmer circuits. Featuring an elongated 20mm handle, this control ensures easy mounting and comfortable manual adjustment through thick equipment panels.
Precision B100K Resistance: Utilizes a linear (B) taper for a consistent, predictable increase in resistance, allowing for accurate power modulation.
Extended 20mm Handle: The long, knurled metal shaft is perfect for reaching through deep chassis or custom control plates, providing plenty of room for secure knob attachment.
Robust Dual-Mounting Design: Equipped with both solder lugs for secure wiring and a threaded metal collar with an included nut for firm panel mounting.
High-Durability Housing: Features a reinforced black base and a protective metal cap to ensure the resistive element is shielded from dust and physical damage.
Tactile Control: Provides a smooth, weighted rotation that allows users to dial in the exact temperature or brightness level needed without drifting.
The VR B100K 20mm Handle Potentiometer is the ideal replacement for:
Electric Instant Water Heaters: Controlling the current to heating elements for precise water temperature regulation.
Industrial Dimmer Switches: Managing lighting levels in high-wattage professional environments.
Voltage Regulators: Serving as a variable resistance tool in power supply calibration and testing modules.
HVAC Control Panels: Adjusting fan speeds or heating thresholds in domestic climate control systems.
Model: VR B100K.
Resistance Value: 100KΩ.
Handle Length: 20mm (including shaft).
Terminals: 3-Pin Solder Lugs.
Is the 20mm handle too long for my device?
The 20mm length is a standard "long handle" size. It is specifically designed for units where the control board is set back from the front cover, ensuring the knob still sits flush and accessible on the outside.
Can this handle high-wattage loads directly?
This potentiometer acts as a control signal, typically wired to a TRIAC or control board. It should not be used to switch high-current heating elements directly without a supporting power circuit.
Is it compatible with other 100K dimmers?
Yes, as long as your existing unit uses a Linear (B) taper. The B100K value is standard for most electronic dimming modules used in household appliances.
