VR 50K-2 VOLUME CONTROL WITH MOTOR

Remote Precision: VR 50K-2 Motorized Volume Control Potentiometer 

Elevate your audio projects with the VR 50K-2 Motorized Volume Control. This specialized component combines a high-quality dual-gang stereo potentiometer with an integrated DC motor, allowing for both manual and remote-controlled volume adjustments. Rated at 50KΩ (50KB-2), it is the industry standard for high-end hi-fi amplifiers, receivers, and home theater systems where physical knob movement must synchronize with remote control commands.

Key Performance Features:

• Integrated DC Motor: Features a compact, low-noise motor that physically rotates the potentiometer shaft for seamless remote-controlled operation.

• Dual-Gang Stereo Control: The 50KB-2 configuration manages two audio channels simultaneously, ensuring perfectly balanced stereo output.

• Manual & Automatic Versatility: The knurled metal shaft allows for traditional manual tuning while the motor handles automated adjustments.

• Precision PCB Terminals: Equipped with multi-pin vertical terminals designed for secure through-hole mounting on professional audio circuit boards.

• High-End Build Quality: Constructed with a durable metal housing and a stable resistive element to minimize signal interference and noise during rotation.

Typical Applications

The VR 50K-2 Motorized Potentiometer is perfect for:

• Hi-Fi Stereo Amplifiers: Adding remote volume functionality to custom or vintage audio builds.

• Home Theater Receivers: Synchronizing physical volume knobs with digital control interfaces.

• Studio Equipment: Enabling automated level fading and remote gain control in professional mixing environments.

• Smart Home Integration: Connecting manual audio controls to microcontrollers (like Arduino or ESP32) for IoT audio systems.

Technical Specs:

•  Model: VR 50K-2

•  Type: Motorized Dual-Gang Potentiometer.

•  Resistance: 50KΩ.

Top 3 Customer Questions & Concerns ‍

1. How do I power the motor?

   • The integrated motor typically operates on a low-voltage DC supply (often 4.5V to 6V). You will need a motor driver circuit or a specialized remote control module to handle the bidirectional current.

2. Does the knob still turn by hand?

   • Yes. The internal clutch mechanism allows you to manually turn the volume knob even when the motor is not powered, without damaging the internal gears.

3. Can I use this with an Arduino?

   • Absolutely. By using a small H-bridge motor driver, you can program an Arduino to rotate the potentiometer to specific levels based on sensor input or IR remote commands.
