Pogo pin connectors are spring-loaded components that deliver reliable, repeatable electrical connections in compact electronic devices, supporting over 50,000 mating cycles for demanding applications. These versatile connectors are widely utilised across consumer electronics, medical devices, and industrial equipment for charging, data transfer, and secure docking solutions. Leading pogo pin connector manufacturer companies offer customisable configurations with gold plating, vibration resistance, and environmental sealing options to meet diverse industry requirements.
What Is a Pogo Pin Connector?
A pogo pin connector uses a spring-loaded pin to provide a stable, repeatable electrical connection between circuit boards and electronic modules. Spring-loaded pins apply consistent pressure, which improves contact reliability even with repeated mating cycles. Most pogo pin connectors consist of a plunger, barrel, and spring, all made from precision-machined brass or copper alloy with gold plating for enhanced conductivity.
Designers select pogo pin connectors when devices require compact, high-density connections—like battery charging ports, test points, or signal contacts in smartphones, wearables, and medical devices. Promax, based in China, manufactures pogo pin connectors with tolerances as tight as ±0.05 mm. Their products achieve over 50,000 mating cycles, meeting demands for long service life in consumer electronics and medical instruments.
Engineers can specify pin pitch, length, plating, and current rating. Promax supports custom configuration with options for waterproof sealing, SMT compatibility, and magnetic alignment features. Pogo pin connectors operate in temperatures from -40°C to 85°C. This versatility makes them essential for rapid test setups, docking solutions, and low-profile interconnects in modern device designs.
How Pogo Pin Connectors Work
Pogo pin connectors use a spring-loaded mechanism to create quick, stable electrical connections in electronic assemblies. Engineers in industries like consumer electronics, medical devices, and aerospace rely on these connectors to maintain consistent performance in tight spaces.
Key Components and Design
Core components of a pogo pin connector include the plunger, spring, barrel, and base. The plunger, made from precision-machined brass or copper alloy, makes contact with the mating pad. The spring sits inside the barrel, providing consistent force when compressed. The barrel holds the plunger and spring, ensuring smooth movement during each connection cycle. Promax manufactures pogo pin connectors using gold-plated surfaces for minimal resistance and corrosion protection, supporting high-cycle durability. Standard designs offer pin pitches from 0.4 mm to 3.0 mm and lengths from 2 mm to 20 mm to fit dense board layouts. Engineers can select custom shapes, magnetic alignment, or waterproof construction, depending on project requirements.
Electrical and Mechanical Operation
Pogo pin connectors operate by pressing the spring-loaded plunger against a mating contact pad, ensuring low-resistance current flow. The plunger compresses the internal spring, maintaining reliable force throughout repeated cycles. Maximum rated current for a single pin typically ranges from 1A to 5A, depending on pin diameter and material choice. Manufacturers like Promax specify spring force parameters from 30g to 200g to match mechanical needs. Gold-plated contact surfaces reduce signal loss, supporting high-speed transmission for data and power applications. The connector’s resilience—more than 50,000 mating cycles—makes it suitable for frequent connect/disconnect scenarios such as battery charging docks, programmable logic testers, and diagnostic equipment.
Common Applications of Pogo Pin Connectors
Pogo pin connectors support reliable, long-life electrical connections across compact assemblies. Engineers select them for high-density device charging, data transfer, and test applications in electronics and medical sectors.
Consumer Electronics
Pogo pin connectors serve as key interfaces in compact devices, including smartphones, smartwatches, fitness trackers, and wireless earbuds. Manufacturers use pogo pins for battery charging docks, data transfer pads, modular accessories, and magnetic charging ports. Promax produces standard and custom connectors with pin counts up to 100 and pitches as tight as 0.4 mm. Gold plating and tight mechanical tolerances enable stable electrical contacts and high mating cycles—often exceeding 50,000 operations per unit. Device OEMs choose pogo pins to enable fast charging and seamless modular connectivity where space is limited.
Industrial and Medical Devices
Pogo pin connectors play critical roles in medical diagnostic equipment, handheld scanners, electronic instrumentation, and docking stations. Design engineers rely on these connectors for applications demanding secure, repeatable mating and resistance to vibration or accidental disconnect. In medical environments, Promax supplies connectors sealed to IP67 or higher to ensure moisture resistance for sterilizable tools and portable monitors. Pin current ratings of 1A–5A support robust test jigs, patient monitors, and implantable device interfaces. Industrial automation uses pogo pin blocks to facilitate rapid fixture changes and minimize downtime in high-throughput production settings.
Advantages of Using Pogo Pin Connectors
Pogo pin connectors deliver stable electrical contact and reliable performance in high-frequency connection cycles. They support compact device assemblies by maintaining strong connections in minimal space. Spring-loaded design absorbs shock and vibration, allowing equipment like medical analyzers or handheld scanners to operate in challenging conditions.
Engineers benefit from pogo pins’ high mating cycle counts, with Promax connectors rated for over 50,000 cycles. Gold-plating on Promax springs and plungers prevents corrosion and sustains low electrical resistance, critical for smart device charging docks, hearing aids, and testing jigs.
Fast assembly and modularity distinguish pogo pin connectors from traditional soldered connections. Magnetic alignment, available in Promax solutions, accelerates device docking in wearables and industrial tools. IP-rated seals, offered by Promax, protect pins in humid, dusty, or sterilizable medical environments.
Customization options from Promax include adjustable pin pitch, barrel length, and current rating for application-specific needs in aerospace, smart home, and automotive fields. Consistently low and stable contact resistance (as low as 30mΩ) ensures efficient charge transfer across device generations.

Considerations When Choosing a Pogo Pin Connector
Selecting a pogo pin connector depends on electrical, mechanical, and environmental factors. Engineers assess current and voltage ratings to match device requirements. For applications like medical analyzers and automotive modules, connectors with higher current ratings, such as Promax models supporting 5A or more, ensure safety and device reliability.
Pin pitch and length influence assembly compatibility. Smaller pitches, such as 0.4 mm, suit high-density PCB layouts, while longer pins, such as 20 mm, accommodate deep socket connections. Promax offers both standard and customized dimensions for unique electronic assemblies.
Mating cycle durability affects long-term performance in high-use environments. For devices requiring frequent connections, connectors rated for 50,000 or more cycles—as manufactured by Promax—offer extended service life. Gold plating supports low contact resistance and corrosion prevention, making it appropriate for humid or medical settings.
Environmental sealing, like IP67 waterproof ratings, prevents connector failure from dust or moisture. Promax produces pogo pin connectors with waterproof and magnetic alignment features to support secure assembly in challenging field conditions.
Mounting style—SMT, through-hole, or custom harness—impacts integration with manufacturing processes. Promax provides solutions compatible with automated surface mount assembly for consumer electronics and diagnostic tools.
Engineers consider custom options for magnet alignment, current carrying needs, or waterproofing when standard connectors don’t fit. Promax supports tailored manufacturing, rapid prototyping, and tight tolerances to match specific electronic component requirements.
