Pogo pins

Pogo pins (spring-loaded contacts) – compact, durable, reliable

Pogo pins (spring contact pins) are spring-loaded contact pins for repeatable, reliable contacting in test systems, docking interfaces, and connector applications. From standard spring contacts to waterproof (IP) and magnetic solutions, we support selection, engineering and sourcing – as a standard or custom design.

Your benefits:

  • Repeatable contacting through defined spring force and suitable tip geometries

  • Long service life: depending on design up to 1,000,000+ contact cycles with stable electrical characteristics

  • Compact form factor for space-saving, high-density designs

  • Flexible integration: SMT/SMD (reflow) and THT, as a single pin or as a contact assembly

  • Special variants: e.g. high-current and RF pogo pins as well as IP-rated and magnetic solutions

  • Custom options: length, stroke/spring force, tip design, as well as plating/surface finish and material pairing

Pogo pins: Contact Pins for Testing, Docking and Modular Systems

Whether test fixture, docking station or service interface: pogo pins are used wherever contacts must be made frequently, compactly and repeatably – often without conventional connector geometries with bulky plug/socket pairs. For stable electrical characteristics over many contact cycles, the overall system is decisive: spring contact pin, mating contact surface, and mechanical guidance.

Pogo pin connectors & contacting solutions

Many inquiries are not about “the one” pogo pin, but about a complete contacting solution: multiple spring contact pins in an array/strip, defined mating parts and mechanical guidance that reliably handles docking and tolerances. Such pogo pin connectors are particularly beneficial when positioning, repeatability and serviceability are key – for example in docking, testing or modular assemblies.

Such contacting solutions are typically used for:

  • Test, programming & service applications
    Temporary contacting for test fixtures, flashing, debugging, calibration and diagnostics of PCBs, assemblies and modules
  • Docking, charging & power transfer
    Repeatable docking as well as battery/charging contacts for power and data transfer – also in connector and cable systems
  • Pluggable & modular connections
    Board-to-board contacting and defined contact points for modular, replaceable units and cabled connections without conventional connectors
  • Space-critical & mechanically stressed applications
    Reliable contacting with limited installation space, high cycle counts, and to compensate tolerances, movement and vibration
  • Environmentally exposed applications
    Use in humid, dusty or vibration-prone environments, e.g. with IP-rated pogo pin variants

Below you will find the most important variants – including high-current, RF and SMT/SMD versions as well as IP-rated and magnetic solutions.

Standard pogo pins

Standard pogo pins are the most common version and are used in numerous applications – from simple PCB contacting to complex docking interfaces. They are available in many designs and can be configured, for example, by pin diameter, stroke, spring force, and tip geometry.

Key selection parameters:

  • Installation height / available space and mechanical tolerances
  • Stroke and spring force matched to the contact surface
  • Tip geometry (e.g. crown/dome/flat) for pads or mating contacts
  • Plating/material pairing (contact stability, wear, corrosion)
  • Single contact vs array/assembly (guidance/positioning)
  • Optional: mounting method (e.g. SMT/SMD soldering vs other fixing methods)

Waterproof pogo pins (IP67/IP68)

For applications with moisture, splash water or cleaning cycles, IP-rated pogo pins are used. Not only sealing and materials are decisive, but also the correct integration into the housing and mating contact – so that the IP rating is achieved in real operation and contacting remains stable long-term.

Magnetic pogo pin connectors

Magnetic pogo pin connectors simplify mating when fast handling, defined positioning or a robust docking interface are important. Relevant factors are magnetic guidance, contact geometry and mechanical stability so that the contact remains repeatable over many cycles.

High-current pogo pins

High-current pogo pins (high-current contact pins) are designed for applications in which spring contact pins must transfer not only signals but also significant currents safely – e.g. docking interfaces, power handover points or power-near modules. The overall interface concept is decisive: contact area, spring force, materials/plating, thermal behavior and mechanical guidance.

Key selection parameters:

  • Current profile (rated current, peaks, duty cycle)
  • Contact area & spring force (stability, wear)
  • Material pairing / plating (corrosion, abrasion)
  • Mechanical guidance (avoid lateral forces, ensure repeatable docking)

High-frequency pogo pins (RF)

RF pogo pins are used when defined signal transmission characteristics are required in addition to mechanical contacting. Geometry, integration (pin/mating contact/environment), contact stability and repeatable mechanical guidance largely determine performance. For RF applications we therefore always consider the complete interface – not just the individual spring contact.

SMD pogo pins (for SMT assembly)

SMD pogo pins are designed for SMT assembly and reflow soldering and are particularly suitable for compact PCB interfaces. They are a good choice when manufacturability in series production, repeatable assembly and minimal installation space are key – for example, PCB-level docking contacts or test-near interfaces.SMD-Pogo-Pins sind für SMT-Bestückung und Reflow-Löten ausgelegt und eignen sich besonders für kompakte PCB-Interfaces. Sie sind sinnvoll, wenn Serientauglichkeit, reproduzierbare Montage und geringer Bauraum im Vordergrund stehen – etwa bei Docking-Kontaktierung auf Leiterplattenebene oder bei testnahen Schnittstellen.

Layout and process notes (SMT/SMD):

  • Footprint/pad layout (coplanarity, solder volume)
  • Mechanical concept (guidance/support against lateral forces)
  • Process window (reflow, cleaning, mechanical load)
  • Tip geometry/plating matched to the mating surface

FAQs

What are pogo pins typically used for (testing, docking, modular systems)?

Typical applications include test systems/test fixtures (e.g. ICT/FCT, PCB contacting), docking (repeatable docking for charging/connection) and modular systems with defined contact points for interchangeable units. Depending on the application, magnetic guidance, IP protection or high-current/RF variants may also be used.

Typical selection criteria are current/voltage, contact resistance, stroke, spring force, pitch, tip geometry, plating, service life (contact cycles), environmental conditions (e.g. temperature, contamination, IP), mounting type (SMT/SMD or THT), and the nature of the mating contact surface.

Yes. Common variants include standard pogo pins, high-current pogo pins, waterproof versions (e.g. IP67/IP68), magnetic pogo pin connectors and HF/RF-capable solutions. They also differ in tip geometries (e.g. crown/dome/flat) and mounting types such as SMT/SMD (reflow) or THT – as a single pin or as a contact assembly.

Yes. Typical custom parameters include length, stroke, spring force, tip design, pitch, plating, insulation/sealing concept, and integration as a connector/assembly. In practice, this starts with a brief alignment of requirements (current, environment, service life, mating contact, assembly process), followed by samples/validation and final specification.

Yes. There are SMT/SMD variants for reflow processes as well as THT versions for through-hole mounting. Important distinction: often the device under test is not soldered; instead, pogo pins are part of the test/docking hardware and contact the mating surface without a fixed solder joint on the counterpart (e.g. pads on PCBs).

A consistently low contact resistance is primarily achieved through the coordinated combination of plating/surface finish (often gold), contact force, suitable tip geometry and an appropriate mating contact surface. A defined compression (stroke) and a mechanical design that minimises lateral forces and micro-movements are also important. Specific values depend on the design and should be matched against the datasheet and the requirement.

For high-current applications, contact area/tip geometry, contact force, thermal behaviour, suitable material and plating combinations, and the mating contact surface are decisive. Stable mechanical guidance and sufficient margin against heating and voltage drop are also important. Current ratings depend on the design and should be tested/validated based on the datasheet and the application.

Yes, there are versions with IP protection, e.g. for environments with moisture, splash water or cleaning processes. The achievable protection rating depends on the sealing concept, the integration (connector/assembly), the mating part and the real application (e.g. cycles, media, temperature).

Pogo pins (spring contact pins) enable compact, repeatable contacting for frequent docking or testing. With suitable mechanical guidance, they are more tolerant of small offset/angle deviations than classic plug/socket pairs. They are also suitable for high mating cycles and support modular concepts where units are regularly exchanged or docked.

In principle, yes – provided the interface is mechanically designed correctly. Key factors are guidance/support, appropriate contact force, suitable material pairing/plating, and a design that reduces micro-movements (fretting) and lateral forces. For demanding environments, redundant contacts, suitable tip geometries and a defined docking mechanism are used as required.
EN Question: Can pogo pins be assembled automatically?

Yes, depending on the design. SMT/SMD pogo pins are typically designed for SMT processes (including reflow); footprint, coplanarity and solder paste deposition are particularly important. THT variants can also be processed automatically depending on the design. The right option depends on mechanical loads, available space, process requirements and volumes.

Yes, for certain applications there are RF-/HF-optimised contact solutions. Defined impedance routing, mechanical stability, suitable geometry and the connection method are decisive. Whether an RF solution is appropriate depends strongly on frequency range, layout and system requirements.
