Spring Loaded Pogo Pins & Connectors

What are Pogo Pins?

Pogo pins (contact pins or spring-loaded connectors) create reliable temporary electrical connections. Their unique spring mechanism ensures consistent contact despite misalignment. They also require less PCB space, allowing them to replace older low-current connectors and facilitate device miniaturization since the mid-20th century. This reliable and compact design makes them ideal for charging ports, data transfer, and testing applications.

Pogo Pin Components

A pogo pin usually consists of 3 to 4 components, including the barrel, the spring, the pin and the optional housing, which all work in perfect sync to help provide connectivity.

Barrel

The barrel acts as a sturdy outer casing which provides structural support and protects the delicate internal components from external impact. It also guides the movement of the pin, by keeping it centered and preventing excessive lateral movement.

Spring

The spring is the heart of the pogo pin's functionality, it is typically a coiled conductive metal structure that will create a constant pressure, to ensure that the pin maintains a firm connection with the mating surface, even with slight variations in alignment. The spring can also be compressed and extended, which allows the pogo pin to absorb some shock or vibration, thus preventing accidental disconnections.

Pin (Plunger)

The Pin or plunger is the conductive tip of the pogo pin that is lodged directly above the spring coil, allowing it to retract and touch the barrel when external force is applied. When the plunger comes into contact with an electric current, it will transmit the current to the other end, to facilitate the electrical flow within the pogo pin. The size of the contact area formed when the plunger touches another conductor also plays a crucial role. The larger this contact area, the lower the resistance to electrical current flow.

Housing

Additionally, a housing component can be used to neatly encase and organize multiple pogo pins, to create a multi-pin connector. It ensures proper spacing between individual pins and provides a secure, unified structure for connecting to the PCB or mating surface, which is necessary to accommodate multiple connections simultaneously in complex circuitry.

Mounting Types of Pogo Pin

Pogo pins come in various mounting configurations to suit different assembly needs, common mounting types include: SMT/SMD, Through Hole, Double-Ended, High Current, Right Angle, Bending Type, Solder Cup, Thread Screw, DIP Mounting.

ATTEND currently offers SMT pogo pins, through-hole mounting pogo pins and DIP pogo pins, catering to multiple applications.

SMT (Surface Mount Technology)
These pogo pins are soldered directly onto the PCB surface, and offer a compact, space-saving design, which is suited for modern, miniaturized electronics. Plus, SMT facilitates faster and more automated assembly processes, leading to quicker production times.

Through-Hole Mounting
Through-hole pogo pins have leads that pass through holes in the PCB and are soldered on the other side. This method provides a robust mechanical connection, ideal for applications requiring high durability and resistance to shock or vibration.

DIP (Dual In-Line Package)
DIP pogo pins have plug-in mechanisms, allowing them to be easily placed onto the PCB by hand before being soldered in place. It's also easier to inspect and rework compared to through-hole mounting, making it suitable for on-site maintenance. Though this mounting method is no longer common in modern devices, they are still highly compatible across multiple vendors.

Pogo Pin Application

Pogo pins offer diverse applications across various industries as they can create convenient yet robust electrical pathways. Common uses include:

Device Charging: Pogo pins ensure secure and efficient power transfer for portable devices such as smartphones, tablets, and handheld computers.
Equipment Testing: Pogo pins are ideal interfaces for diagnostics and analysis because they offer a reliable and repeatable connection to the device under test (DUT), allowing engineers to obtain accurate readings.
Signal Transmission: With low contact resistance, pogo pins can maintain a stable connection even at high frequencies. So, not only are they suitable for conventional memory connectors, but they can also withstand the high data transfer rates in IoT applications and POS terminals without major signal loss.
Board-to-Board Connections: Due to the pogo pin’s compact design, it is often used for direct connections between internal printed circuit boards (PCBs) to save space.

Excellent Mechanical Features

🧩 Compact and Space Efficient
Our pogo pins are sleek and lightweight, with basic working heights of 2.6~7.5mm and diameters of 1.80~1.83mm for single-pin connectors. Some of our pogo pins also support board-to-board (B2B) connections, eliminating the need for wiring in space-constrained circuit boards.

🔩 Great Durability and Strength
Leveraging precision CNC machining, quality materials, and high-precision design, we create strong and long-lasting pogo pins that can withstand 10,000 to 50,000 mating cycles. If you need specialized applications, we offer simulation analysis to help you select the most suitable spring plunger and ensure durability.

⚡ Reliable Electrical Connectivity and Performance
Our pogo pins, rated at 1-3 amps, can deliver efficient performance without compromising safety. They maintain optimal contact pressure even under slight misalignments, offering stable electrical connections and enhanced shock resistance due to the wide spring force range exceeding 0.5N~1.5N. Their contact resistance is also minimized to around ≤20mΩ thanks to smooth, high-conductivity materials like gold-plated brass.

🌡️ Harsh Environment Tolerance
ATTEND uses durable materials like stainless steel and phosphor bronze with protective gold plating for superior resistance against moisture and corrosion. Our pogo pins endure temperatures from -40°C to +85°C, preventing deformation under extreme conditions and ensuring reliable connections in demanding applications.

Quality Material

Pin (Plunger): Made from brass coated with gold or nickel for durability, corrosion resistance, hardness and excellent conductivity.
Spring: Made from stainless steel as the material has strong resilience to ensure a consistent spring force over extended use. It also boasts resistance towards corrosion and high temperatures, while having non-magnetic properties to ensure smooth operation.
Barrel: Commonly made from brass or phosphor bronze. Brass is a cost-effective option that is also valued for its good formability, which allows the creation of various barrel shapes; phosphor bronze, though more costly, offers a good balance of conductivity and formability, while providing superior corrosion resistance compared to brass.
Housing: Made from Thermoplastic LCP (Liquid Crystal Polymer) PA6T that can withstand higher temperatures and many types of chemical, allowing it to maintain its shape under varying harsh conditions and mechanical stress better than traditional thermoplastics. This housing material also offers good insulating properties to prevent electrical shorts and ensure safe operation.
