Pogo pin connectors are essential components in a wide range of modern devices.
Whether you’re designing a smartwatch, running automated tests on PCBs, or building a charging dock, these small spring-loaded connectors provide the flexibility and reliability you need.
In this [2025] guide, we’ll cover everything you should know before buying pogo pins: how they work, what makes them different from other connectors, what to look for in terms of specs, and which brands to trust.
What Are Pogo Pin Connectors?
Pogo pin connectors, also known as spring-loaded connectors, are compact, precision-machined components used to make temporary or permanent electrical contact between two devices.
pogo pin
Each pogo pin consists of a plunger, a barrel, and a spring.
When pressure is applied, the spring compresses, allowing the plunger to make contact with the mating surface.
Once pressure is released, the spring returns the plunger to its original position.
They’re popular in electronics because they handle thousands of cycles without degrading.
They’re ideal for test jigs, docking stations, medical devices, and more.
These pins come in various lengths, diameters, and current ratings, making them highly versatile.
Many are also gold-plated to improve conductivity and resist corrosion, important in high-use or outdoor environments.
Why Pogo Pins Are Crucial in Modern Electronics
As devices get smaller and smarter, pogo pins have become more important than ever.
They offer high-reliability connections in tight spaces, which traditional connectors can’t always support.
Their compact design allows manufacturers to reduce the overall size of products without compromising on performance.
They’re also less likely to wear out, making them ideal for products that need to be tested frequently or charged often.
In industries like wearables, telecom, medical tech, and consumer electronics, pogo pins are the go-to solution for ease of connection, longevity, and durability.
In 2025, innovation in battery-powered and modular devices continues to push the need for better connection solutions.
That’s where pogo pins shine.
Key Factors to Consider Before Buying in [2025]
Pin Material and Plating
The core material of a pogo pin affects conductivity and resilience.
Brass and beryllium copper are commonly used for their strength and electrical performance.
Most high-quality pogo pins are plated with gold.
Gold resists oxidation, ensures stable contact, and offers excellent conductivity, especially important in low-voltage applications.
Nickel is often used as a base layer under gold for durability.
Spring Force and Compression
Spring force determines how much pressure is needed for contact.
Too much, and it may damage delicate components.
Too little, and the contact might be unreliable.
Look for pins with compression ranges suited to your application—typically between 0.5mm and 3.0mm.
Current Rating and Durability
Different applications require different current capacities.
Low-current pins (below 1A) are fine for signal transmission, while high-current designs (up to 10A) are used for power.
Also, check the cycle life.
A good pogo pin should last at least 10,000 insertions without losing performance.
Common Types of Pogo Pin Connectors
Pogo pins come in a variety of configurations.
Here are the most common types:
-
Through-hole pogo pins: Inserted directly into a PCB. Good for strong mechanical retention.
-
SMD pogo pins: Surface-mounted for smaller form factor boards. Ideal for compact electronics.
-
High-current pogo pins: Designed with larger barrels and plungers to carry more power.
-
Double-ended pogo pins: Often used in test equipment where two surfaces need to be connected.
-
Custom pogo pin arrays: Tailored for proprietary systems or tight tolerances.
Each type serves a specific purpose.
Choosing the right one means evaluating size constraints, mating cycles, and the nature of the electrical load.
Top Applications in [2025]
In [2025], pogo pin connectors continue to be a top choice in fast-growing sectors:
