WH0141-1(14X1)

Product Overview

WH0141-1(14X1) is an ultra-thin, edge-driven potentiometer featuring a flat dial design with the edge exposed. It is specifically engineered for miniature portable electronic products where space is extremely limited. This product replaces the traditional rotating shaft of a rotary potentiometer with a horizontally extended flat plastic disc; once installed, the edge of the disc protrudes from the device’s housing. Users can adjust resistance by flicking the disc’s edge, providing excellent tactile feedback even when operating blindly. The resistor element typically employs a carbon film structure, with a thickness of only 2mm to 4mm, achieving an exceptionally high degree of height-space compression. It perfectly fits into compact portable electronic enclosures with stringent thickness requirements, while also meeting the biocompatibility and miniaturization standards of medical-grade hearing aids, helping reduce product volume by up to 20% and enhancing wearing comfort.

Operating Principle

This potentiometer is based on the core principles of rotary potentiometers, but replaces the conventional long rotating shaft with a horizontally extended flat plastic disc. After installation, the edge of the disc remains visible outside the device’s housing. Users do not need to see the potentiometer itself—by simply flicking the disc’s edge with their fingers, they can move the internal sliding contact along the resistor element, precisely adjusting resistance. This design eliminates the traditional long shaft that protrudes outward, achieving both resistance adjustment and maximum height-space reduction, while delivering convenient blind operation.

Core Advantages

1. Ultra-thin design: With a thickness of only 2mm–4mm, and a minimum achievable below 2mm, this product offers exceptional height-space compression, easily fitting into compact portable electronic housings that demand extreme thinness. It solves the longstanding challenge of traditional long-shaft potentiometers being incompatible with ultra-thin devices.
2. Excellent blind-operation feel: Featuring an exposed-edge flat dial design, users can adjust resistance simply by flicking the disc’s edge without visual confirmation, making it especially convenient for devices worn on the ear or carried in pockets.
3. Medical-grade compliance: Meeting biocompatibility requirements for medical-grade hearing aids, it can be safely used in hearing aids and other close-fitting medical electronics, ensuring user safety.
4. Supports product miniaturization: With minimal physical dimensions of 10mm diameter and 2mm thickness, it helps reduce overall product volume by up to 20%, significantly improving the comfort and portability of portable devices.
5. Stable and durable performance: The carbon film resistor structure ensures stable operation, with a rated power of 0.05W, satisfying the low-power adjustment needs of miniature electronic devices and delivering reliable long-term performance.

Core Value of the Product

1. Its ultra-thin structure breaks through spatial limitations, enabling ultra-thin industrial designs for miniature portable electronics without requiring extra height space for the potentiometer.
2. The blind-operation design enhances user experience, particularly for devices like hearing aids and in-ear headphones that cannot be operated visually, making control more convenient.
3. Medical-grade compliance ensures safe application, allowing direct integration into close-fitting medical devices such as hearing aids without additional compliance testing.
4. By reducing product volume by up to 20%, it improves the wearing comfort and portability of portable devices, strengthening market competitiveness.

Target Customer Groups

Hearing aid manufacturers, portable pocket radio producers, handheld gaming peripheral suppliers, over-ear headphone makers, and other companies focused on developing and producing miniature ultra-thin electronic devices. These enterprises generally face strict height-space constraints while demanding ease of operation and high compliance standards. This potentiometer perfectly aligns with their product design needs.

Application Scenarios

Specifically designed for miniature ultra-thin electronic devices, this potentiometer is primarily used in the following scenarios: adjusting volume on behind-the-ear hearing aids, leveraging its ultra-thin form factor to integrate seamlessly into the hearing aid housing, allowing users to conveniently regulate volume through blind operation; controlling volume on in-ear wired headphones, adapting to the ultra-thin design of the headphone cable so users can easily adjust volume while wearing them; fine-tuning screen backlight brightness on retro handheld gaming consoles, embedded within the console’s slim body, enabling users to adjust backlight intensity according to ambient lighting conditions for an enhanced user experience. Additionally, it can be applied to other miniature electronic products with limited height space that require blind-adjustment functionality.

Solutions to Industry Pain Points

In the research and production of miniature, ultra-thin electronic devices, the long-shaft design of traditional rotary potentiometers has long been a major design challenge: the protruding shaft cannot fit into ultra-thin housings, forcing awkward installations that compromise the overall design and may even render the device unportable. WH0141-1(14X1), however, perfectly addresses this issue. With its flat dial edge-driven design, it completely eliminates the long-shaft structure, compressing the height to just 2mm–4mm and fulfilling the “hidden” and “edge-sliding” industrial design requirements of these devices. Meanwhile, its blind-operation feature resolves the problem of users being unable to operate close-fitting, portable devices visually, and its medical-grade compliance tackles the safety adaptation challenges faced by hearing aids and other medical devices, comprehensively meeting the design and usage needs of miniature ultra-thin electronics.
