Turning
Every pogo pin component starts on precision CNC turning equipment, machined to tight tolerances for a consistent fit between plunger, barrel, and spring.
Pogo Pin Supplier: Standard and Custom Spring-Loaded Pins, Made in Dongguan
Spring-loaded pogo pins (also called spring probes or contacts) are precision electrical connectors that ensure reliable, temporary connections between circuits and components. A built-in spring maintains consistent contact while accommodating mechanical tolerances and misalignment. Each pin features three machined parts—a spring-loaded plunger, a barrel housing, and an internal compression spring—and can endure hundreds of thousands of mating cycles while offering low electrical resistance and high reliability in demanding applications.

Promax Pogo Pin Key Operating Parameters
A spring-loaded pogo pin creates an electrical connection when its plunger contacts the mating surface and compresses into the barrel. The internal spring maintains consistent contact force, helping the connection remain stable under vibration, thermal expansion, and repeated use.
Working Heights and Force Specifications:
- Free Height: The fully extended position with no applied load
- Working Height: The optimal operational position providing ideal spring force
- Maximum Compression: The fully compressed position where the plunger bottoms out
Electrical Characteristics:
- Contact Resistance: Typically 20-50 milliohms at mid-stroke
- Current Rating: From 2-9 amps continuous depending on pin configuration
- Voltage Rating: Up to several hundred volts depending on application
- Cycle Life: 10,000 to 1,000,000+ cycles depending on design and application

Gage R&R (ANOVA) for Press Fit
We leave nothing to chance regarding quality control. For our press fit, we analyzed 100 pressure data points using the GR&R method. To ensure thorough testing, we had three technicians test the reproducibility and repeatability of the press fit across 10 different products. Our commitment to precision is unwavering, and our quality control measures are among the most rigorous in the industry. When you choose us, you choose excellence.
Application Scenarios of Spring Loaded Pogo Pins
Spring loaded pogo pins are the contact element of choice anywhere a PCB designer needs a high-cycle, blind-mate, low-resistance interface that survives 100,000+ mating cycles. Because pins are sold loose (in tape and reel, tray, or tube), engineers select by mount type, profile, termination, and current rating — then reflow, wave-solder, press-fit, or wire-terminate them onto their own boards. Below are the nine application areas where Promax pogo pins are designed-in most often:
Consumer Wearables, Earbuds & Smartphone Charging Contacts
Smartwatches, TWS earbud cases, fitness trackers, smart glasses, and 2-in-1 laptop hinges expose SMT/SMD pogo pins reflowed directly onto the device PCB as the charging-contact face. The 0.4–1.0 mm pitch options and low-profile heights fit inside ultra-thin enclosures, and gold-over-nickel plating tolerates 10,000+ daily charging mates without contact-resistance drift.
PCB Testing, ICT, FCT & Burn-In Fixtures
Bed-of-nails fixtures, in-circuit test (ICT) jigs, functional test (FCT) rigs, programming sockets, boundary-scan adapters, and burn-in boards rely on spring contact probes (pogo test pins) to make non-destructive, repeatable contact with PCB test pads, BGA balls, and gold fingers. Cycle-life ratings up to 1,000,000 mates and contact resistance under 50 mΩ keep yield numbers honest across long production runs.
Medical Devices, Diagnostic Probes & Disposable Cartridges
Continuous glucose monitors (CGMs), hearing-aid charging cradles, ECG patches, intra-oral cameras, surgical-tool tips, and single-use diagnostic cartridges integrate gold-plated SMT/SMD and through-hole pogo pins as the device-to-cradle contact. Biocompatible plating (gold over nickel, 30µ” minimum) tolerates repeated wipe-down disinfection, supporting ISO 13485 traceability requirements.
Electric Vehicles, E-Mobility & Battery Pack Contacts
EV battery management systems (BMS), lithium battery pack interconnects, e-bike charging cradles, cordless power-tool packs, and portable power-station modules use high-current pogo pins carrying up to 15 A continuous. T-pin, ball, and coaxial internal designs keep contact resistance under 30 mΩ for sustained-load thermal stability, with bias-tail variants for <3 A signal/sense lines on the same pack header.
5G, RF & Wireless Communication Modules
5G small-cell base stations, MIMO antenna feeds, Wi-Fi 6E modules, RF test fixtures, and wireless IoT gateways use compact SMT/SMD pogo pins for controlled-impedance board-to-board signal transmission. Silver-plated pins enhance conductivity for high-frequency designs in the sub-6 GHz band, and the consistent contact pressure preserves signal integrity through vibration and thermal expansion.
Industrial Automation, Robotics & Smart Meters
Robotic end-of-arm tooling, AGV/AMR charging contacts, modular factory sensors, smart electricity meters, and quick-change tooling heads use bending-type pogo pins and solder-cup pogo pins to handle 24/7 docking duty cycles. The compliant spring travel (1–3 mm) absorbs mechanical tolerance stack-up that would damage rigid screw or pin-header connectors.
Smart Cars, ADAS & In-Vehicle Electronics
Infotainment dock connectors, ADAS sensor modules, dashcams, OBD-II diagnostic readers, dashboard cameras, and in-vehicle accessory hubs use through-hole and right-angle pogo pins for robust, vibration-resistant docking. The right-angle profile suits edge-mount applications where the mating axis is parallel to the PCB and vertical board space is constrained.
Aerospace, Defence & Rugged Field Equipment
Field radios, soldier-worn devices, helmet-mounted displays, drone docking stations, satellite communication modules, and ruggedised handhelds specify stainless-steel-housing pogo pins paired with high-current pogo pins for combined power-and-data through a single mating face. Tested to 50 G shock and 10 G vibration minimum, with high-temperature variants up to +150 °C and military-spec plating options for extra-atmospheric deployment.
Board-to-Board Stacking & PCB-to-Wire Harnesses
Mezzanine board stacks, daughter-card interconnects, and modular instrument backplanes use double-ended pogo pins where both ends compress against opposing PCBs. For wire-to-board terminations — sensor harnesses, motor leads, antenna pigtails — engineers spec solder-cup pogo pins for soldered cable tails or thread-screw pogo pins for field-replaceable, screw-in mounting.

Pogo Pin – Frequently Asked Questions
What is the typical lifespan of a spring loaded pogo pin?
Spring loaded pogo pins typically provide 10,000 to 1,000,000+ mating cycles depending on the specific design, application conditions, and quality of materials used. Our standard pins are rated for 100,000 cycles minimum.
How do I determine the right spring force for my application?
Consider your total normal force requirements, the number of pins in your array, and the mechanical compliance of your mating surfaces. Our standard 60-gram force pins work well for most applications, but custom forces are available.
Can spring loaded pins be used for high-frequency signals?
Yes, properly designed spring loaded pins can handle high-frequency signals. Consider controlled impedance designs and proper grounding techniques for optimal signal integrity.
What's the difference between spring loaded pins and traditional connectors?
Spring loaded pins offer temporary connections with built-in compliance for misalignment, while traditional connectors typically provide permanent connections with potentially higher current capacity but less mechanical flexibility.
How do I specify the right plating for my application?
Gold plating offers the best corrosion resistance and contact stability for most applications. Silver provides enhanced conductivity for high-frequency applications, while tin offers a cost-effective solution for less demanding environments.
