Precision Pogo Pin Solutions
for Smart Devices
Compact, reliable electrical contacts for smart glasses, earbuds, laptops, tablets, wearables and hearing aids. Top-Link develops precision Pogo Pin contacts and connector assemblies designed for space-constrained devices and demanding everyday use.
Designed for Compact, Reliable Connections
Miniaturized Contact Design
Fine-pitch Pogo Pin contacts and compact connector designs help meet the limited space and precise alignment requirements of modern smart devices.
Reliable Electrical Performance
Contact force, working stroke and surface finish are engineered to support stable electrical connection throughout the product's intended service life.
Application-Focused Engineering
We work with customers to define contact structures, materials and plating options according to device layout, operating environment and performance requirements.
From Development to Manufacturing
Our engineering and manufacturing teams support product development, design validation and volume production — helping customers move from concept to a manufacturable interconnect solution.
Interconnect Solutions for Different Smart-Device Applications
Each device has its own space, mechanical and environmental requirements. Top-Link develops precision contact solutions to support charging, module connection and other electrical interconnect needs.

Smart Glasses & XR Devices
Compact Pogo Pin contacts and miniature connector solutions for space-limited frames and internal modules. Designs can be tailored to the available layout, contact position and required electrical performance.

Earbuds & Audio Wearables
Precision charging contacts for TWS, open-ear and other wearable audio products. Contact geometry, spring force and plating options can be selected to support repeated docking, stable charging and resistance to everyday perspiration.

Laptops, Tablets & Portable Electronics
Compact spring-loaded contacts and precision interconnect components for portable electronics. Solutions can be customized to fit restricted internal spaces and the mechanical requirements of the device.

Hearing Aids & Medical Wearables
Miniature electrical contacts for hearing-aid modules and selected wearable healthcare devices. Material and surface-finish options can be evaluated against the customer's applicable biocompatibility, corrosion and reliability requirements.
Integrated Charging Contact Assemblies
For projects that require more than a standalone contact, Top-Link can discuss customized charging-contact assemblies based on the product architecture and project scope. Depending on the design, an assembly may incorporate Pogo Pin contacts, magnets, a housing and other specified components.
Every assembly is defined around the customer's mechanical layout, electrical requirements and manufacturing needs.
Engineered for Long-Term Contact Reliability
Stable contact performance depends on more than the pin itself. Contact force, working stroke, surface finish, alignment and the operating environment all influence long-term reliability. Top-Link evaluates these factors during product development and can support verification plans based on the customer's application and acceptance criteria.

Frequently Asked Questions
Can Pogo Pin contacts be customized for compact devices?
Yes. Contact dimensions, spring force, working stroke, mounting approach and plating options can be evaluated according to the available space and electrical and mechanical requirements of the device.
Can Pogo Pin charging contacts resist sweat and humidity?
The contact design and surface finish can be selected to suit the expected operating environment. Reliability requirements should be defined for each project, with relevant humidity or corrosion testing specified where applicable.
Can you provide magnetic charging contact assemblies?
Customized charging-contact assemblies can be discussed based on the product structure and project requirements. The scope may include Pogo Pin contacts and other specified mechanical or electrical components.
How do you support long-term contact reliability?
Key design factors include contact force, working stroke, alignment, surface finish and the expected number of mating cycles. These factors can be evaluated and verified against the product's defined requirements.
Do you support hearing-aid and wearable medical-device applications?
Top-Link can evaluate miniature contact solutions for hearing aids and selected wearable devices. Material selection and verification requirements should be reviewed against the customer's applicable product and regulatory requirements.
