WH0142-1(14X1)

Product Overview

WH0142-1(14X1) is an ultra-thin, edge-driven potentiometer featuring a flat dial design with the edge exposed. It’s specially crafted for miniature portable electronic products where space is extremely limited. This product replaces the traditional rotary shaft of conventional potentiometers with a horizontally extended flat plastic disc; once installed, the disc’s edge 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 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 redesigned based on the core principle of rotary potentiometers, replacing the traditional long shaft with a horizontally extended flat plastic disc. After installation, the disc’s edge remains visible outside the device’s housing. Users don’t need to see the potentiometer itself—simply flicking the disc’s edge moves the internal sliding contact along the resistor element, precisely adjusting resistance. This design eliminates the protruding long shaft found in conventional potentiometers, achieving both resistance adjustment and maximum height-space reduction, while delivering convenient blind operation.

Core Value of the Product

1. The ultra-thin structure breaks spatial limitations, enabling ultra-thin industrial designs for miniature portable electronics without requiring extra height space for potentiometers.
2. The blind-operation design enhances user experience, particularly for devices like hearing aids and in-ear headphones that cannot be operated visually, offering greater convenience.
3. Medical-grade compliance ensures safe application, allowing direct integration into personal 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, boosting 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 control volume through blind operation; controlling volume on in-ear wired headphones, compatible with the ultra-thin design of headphone controls, enabling users to adjust volume effortlessly while wearing them; fine-tuning screen backlight brightness on retro handheld gaming consoles, embedded within the console’s slim body, allowing users to adapt backlight intensity according to ambient lighting conditions and enhance their overall 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 of traditional rotary potentiometers has long been a major design bottleneck: the protruding shaft cannot fit into ultra-thin housings, forcing awkward installations that compromise the overall design and sometimes render the device unusable. WH0142-1(14X1), however, perfectly resolves this issue. With its flat dial-edge drive design, it completely eliminates the long shaft, compressing the height to just 2mm–4mm and fulfilling the “hidden” and “edge-sliding” industrial design requirements of modern devices. Meanwhile, its blind-operation feature addresses the challenge of users being unable to operate personal, portable devices visually, and its medical-grade compliance solves the safety adaptation issues faced by hearing aids and other medical devices, comprehensively meeting the design and usage needs of miniature ultra-thin electronics.
