Spring Loaded Side Contact Pin Catalog
Side contact pogo pin, also known as spring loaded side contact pins, side contact spring contacts, or through hole spring loaded side contact pins, are primarily used to establish reliable electrical or signal connections between components. They ensure consistent conductivity and stable contact performance in various electronic applications.
Side Contact Pogo Pins Overview
Side Contact Pogopin Product Details
With advanced technology and expert craftsmanship, we create durable, high performance custom side contact pogo pin / side contact spring connector pin tailored to each project’s needs.
What is side contact pogo pin
Side contact pogo pin is a type of spring loaded electrical connector designed to make contact on the side surface of a mating pad, rather than pressing straight down like a traditional pogo pin. Inside, it has a plunger, spring, and barrel, but the plunger is shaped or angled so it applies lateral force.
Side contact pogo pins are commonly used when vertical space is limited, when the mating surface is on the edge of a PCB, or when designers want better tolerance for misalignment. They are also useful in rotating, sliding, or docking connections.
Typical applications include wearable devices, smart phones, battery contacts, test fixtures, and compact consumer electronics. Their main advantages are compact design, reliable contact under vibration, and flexibility in mechanical layout.
How to install side contact pogo pin
Installing a side contact pogo pin requires careful mechanical and electrical alignment. First, prepare the PCB or housing with the correct mounting hole or slot, ensuring dimensions match the pogo pin specifications. Insert the pogo pin into the hole so that the side contact area faces the mating pad. Depending on the design, secure the pin by press fit, soldering, or adhesive fixing. For soldered types, apply controlled heat to avoid damaging the internal spring. Next, align the mating PCB or contact surface so it provides sufficient lateral compression when assembled. Verify that the pogo pin can move freely and maintains consistent contact force. Finally, test continuity and mechanical reliability under vibration or repeated mating cycles to ensure stable electrical performance.
side contact pogopin material & parts
A side contact pogo pin is a specialized type of pogo pin connector designed with a bevel structure to enable lateral electrical contact. It is a built in spring connector commonly used in compact electronic designs. The connector typically consists of four main parts: the plunger, solid pin, spring, and body. The plunger and solid pin are usually made of brass or phosphor bronze with gold plating to ensure low resistance and corrosion resistance. The internal spring provides stable contact force. This structure supports SMT automatic reflow soldering, offers high soldering strength with PCB boards, ensures stable and reliable connections, and delivers a long service life with excellent durability.
side contact pogopin Internal structures
Side contact pogo pin adopts plunger bevel structure and plunger inner hole bevel structure. The plunger bevel structure features a precisely machined angled surface on the plunger, which provides a defined side contact area and controlled movement space. The plunger inner hole bevel structure is formed inside the plunger to guide alignment with the spring and body, ensuring smooth, centered positioning during compression. Together, these two structural designs improve mechanical stability, reduce friction and wear, and enhance dimensional tolerance. The optimized bevel geometries support compact assembly, consistent contact positioning, and long term durability in high density electronic connector applications.
How Side Contact Pogo Pins Work
Side contact pogo pins work by converting axial spring force into lateral contact force. Contact force and contact resistance are closely related: higher and more stable contact force results in lower contact resistance and better electrical reliability. Inside the pogo pin, the spring pushes the plunger forward, while the beveled structure guides the plunger to press sideways. This generates a controlled lateral force that keeps the gold plated needle firmly in contact with the inner wall of the needle tube. As a result, the contact area remains stable, oxidation is reduced, and extremely low, consistent contact resistance is achieved for reliable electrical connection.
Dip Pogo Pin Contact Resistance
This chart illustrates that during the full compression and release stroke of the dip pogo pin, the spring force increases smoothly while the contact resistance remains extremely low and stable. This demonstrates a well-engineered internal structure, precise machining tolerances, and high-quality vacuum blind-hole plating that together ensure reliable electrical connectivity and long-term performance stability.
