What Are Pogo Pins?
Pogo pins, also called spring-loaded contacts, are precision-made connectors used to create temporary or permanent electrical pathways between two components. Each pogo pin consists of a plunger, a barrel, and an internal spring. When pressed, the plunger moves inside the barrel and the spring ensures consistent contact pressure. This mechanism allows for repeated mating cycles, making pogo pins ideal for electronic devices that require frequent docking and undocking.
Key features include:
- Reliable, low-resistance connections
- High cycle durability (often exceeding tens of thousands of uses)
- Compact form factor suitable for dense PCB layouts
Pogo pins come in different lengths, diameters, plating options (such as gold for improved conductivity), and tip styles. Manufacturers like Promax custom-design pogo pins to match specific current ratings, mechanical tolerances, and design footprints.
Applications of Pogo Pins in Modern Industries
Pogo pins are widely used across multiple industries due to their versatility and performance. Some of the most common applications include:
Consumer Electronics
Devices like smartphones, smartwatches, and wireless earbuds rely on pogo pins for charging connections and data transfer. The compactness and reliability of these connectors support high-frequency use scenarios, such as docking stations and magnetic charging accessories.
Medical Devices
Precision and reliability are vital where patient safety is concerned. Medical manufacturers use pogo pin connectors in diagnostic equipment, imaging devices, and modular monitoring systems. Gold-plated pogo pins offer biocompatibility and corrosion resistance, which are essential for maintaining signal integrity under rigorous sanitation protocols.
Aerospace and Defense
Aerospace equipment and defense platforms require connectors that withstand vibration, extreme temperatures, and repeated engagement. Pogo pins with enhanced spring force and robust housing are used in avionic systems, test fixtures, and ground support equipment.
Testing and Production Equipment
Automated test equipment (ATE) and programming fixtures commonly incorporate pogo pins for their ability to provide fast and repeatable connections without soldering. This streamlines quality assurance and accelerates production line testing.
Companies like Promax support industries worldwide by offering custom pogo pin designs to address unique mechanical, environmental, and electrical requirements.

Manufacturing Process of Pogo Pins
The manufacturing of pogo pins requires close-tolerance machining and strict process controls to guarantee repeatable performance. An overview of key production steps follows:
1. Material Selection and Preparation
High-conductivity metals such as brass or beryllium copper form barrels and plungers, chosen for strength and electrical performance. Springs are usually stainless steel or music wire to ensure consistent force.
2. Micro Machining and Forming
CNC lathes and precision grinders shape the barrel and plunger components. Surface finishes are carefully controlled to reduce wear and improve current flow.
3. Spring Loading Assembly
An internal spring is fitted between the plunger and the base, assembled using semi-automated equipment to maintain tension consistency across large volumes.
4. Electroplating
Gold or nickel plating is applied to improve conductivity and prevent corrosion. Thickness is measured to ensure compliance with performance standards, often using non-destructive x-ray methods.
5. Quality Assurance Testing
Each finished pogo pin is tested for:
- Contact resistance
- Spring force
- Plating adhesion
- Dimensional accuracy
6. Packaging and Shipping
Pins are packaged according to ESD-safe protocols and labeled for full traceability. Promax, for instance, incorporates 100% final inspection and lot traceability for major OEM customers.
Key Factors to Consider When Choosing a Pogo Pin Manufacturer
When evaluating pogo pin manufacturers, engineers and buyers should focus on the following criteria:
- Consistency and Quality Assurance: Does the manufacturer deliver tight tolerance components and document each stage of inspection?
- Customization Capability: Can they develop custom pin configurations for emerging designs or tight project timelines?
- Certifications and Compliance: ISO 9001, RoHS, and REACH compliance are standard for suppliers serving regulated industries. Promax, for example, maintains these certifications and provides full materials compliance reports.
