Can I use this slide potentiometer with a 3.3V microcontroller like the ESP32?

Yes, the potentiometer acts as a simple voltage divider and works perfectly with both 3.3V and 5V logic systems.

What is the difference between the OTA and OTB outputs?

OTA and OTB are independent analog outputs linked to the same physical slider, allowing you to control two separate circuits simultaneously.

How do I mount this module into a custom control panel?

The PCB features four pre-drilled mounting holes at the corners, allowing you to secure it to a panel using standard M2 or M3 standoffs.

Can I replace the yellow fader cap with a different color?

Yes, the yellow cap can be pulled off and replaced with any standard fader knob that fits the internal metal lever.

Do you sell the necessary DuPont jumper wires at your Sham Shui Po store?

Yes, we stock a wide variety of DuPont cables, breadboards, and Arduino accessories at our Sham Shui Po retail shop.

10K Linear Slide Potentiometer Module (Dual Output)

Name: 10K Linear Slide Potentiometer Module (Dual Output)
Brand: Sun Cheong Computer Company Limited
SKU: 21PS001225
Price: 140.0 TWD
Availability: InStock

Short Product Description

This 10kΩ linear slide potentiometer module provides precise analog control for Arduino and microcontroller projects. Featuring a dual-circuit design with independent OTA and OTB outputs, it allows simultaneous control of two separate voltage levels. Equipped with a dust-resistant fabric cover and a high-visibility yellow fader cap, it is ideal for DIY audio mixers, lighting consoles, and custom control panels.

Key Features

10kΩ Linear Resistance: Provides smooth and proportional analog voltage scaling for accurate control.
Dual Analog Outputs: Features independent OTA and OTB pins to support dual-circuit simultaneous control.
Dust Protection: An integrated fabric cover prevents dust accumulation on the sliding track, ensuring longevity.
Pre-installed Fader Cap: Includes a high-visibility yellow cap for immediate tactile feedback and control.
Easy Integration: Standard 2.54mm pitch headers connect easily to breadboards and jumper wires.

Full Product Description

Precise Analog Control for DIY Projects

This linear slide potentiometer delivers accurate, continuous analog voltage outputs based on the slider's physical position. It is fully compatible with standard microcontrollers like Arduino, ESP32, and Raspberry Pi (via an ADC), making it a reliable input device for custom interfaces. The linear taper ensures that the voltage scales smoothly and predictably as you move the fader.

Dual-Circuit Design for Advanced Routing

The module features two independent 3-pin headers (VCC, GND, OUT), allowing it to process two different voltage levels simultaneously. This dual-channel capability is perfect for stereo audio mixing, or for controlling multiple software parameters from a single physical fader without complex coding.

Technician Tip

When integrating this module into a custom enclosure or panel, ensure you leave an 11mm clearance between the potentiometer body and the fader cap for smooth, unobstructed operation. Our Sun Cheong technical team recommends using standard female-to-female DuPont cables to connect the header pins directly to your microcontroller's analog inputs for fast prototyping.
