Introduction to Spring-Loaded Pogo Pins & Connectors
Spring-Loaded pins—widely known as Spring-Loaded Contacts, Spring probes, or Pogo pin—deliver a highly reliable and precision-made interconnect solution for the most rigorous electronic applications. Every CTP spring-loaded pin is precision-machined to guarantee micro-ohm level low resistance, extended mechanical durability, and a highly resilient compliant connection. Backed by CTP’s advanced manufacturing and rapid 3-day prototyping, our industry-leading designs empower hardware engineers to easily specify and integrate the perfect spring probe for any critical environment.
The Background on Spring-Loaded Pins:
Every CTP spring-loaded pin is precision-machined from three core components and integrated with a high-fatigue internal spring to guarantee stable mechanical travel. Our advanced gold-over-nickel electroplating process delivers micro-ohm level contact resistance and superior corrosion defense. Because of this proven reliability and CTP’s rapid 3-day standard sample turnaround, hardware engineers in demanding sectors—including medical devices, aerospace, military, telecommunications, and industrial automation—have discovered the distinct advantages of integrating our spring-loaded contacts into their next-generation interconnect designs.

High-Performance Spring-Loaded Connector Arrays
For demanding multi-circuit applications, CTP offers premium spring-loaded pins pre-assembled into high-temperature thermoplastic housings. Designed to withstand rigorous assembly processes, our connector arrays deliver consistent mating reliability across various layouts.
- Versatile Pitch Options: Standard arrays available from highly dense .050” (1.27mm) to standard .158” (4.00mm) pitches.
- Custom Pin Patterns: We can selectively load spring probes into specific custom arrays to match your unique PCB footprint.
- Integrated Mounting Hardware: Need enhanced mechanical stability? We seamlessly incorporate threaded inserts and custom mounting fixtures directly into the insulator, ensuring a stress-free connection to your board or substrate.
Omni-Directional Spring-Loaded Contacts for Sliding & Rotational Applications
For applications where standard axial contacts fail, our Omni-directional Spring-Loaded Contacts offer a revolutionary mating surface. Engineered for complex movement, these pins support seamless sliding, blind mating, and “twist & lock” connection profiles.
- Vertical Compression: Featuring .030” (0.762mm) of travel to ensure consistent electrical and mechanical connectivity.
- Self-Cleaning Action: The unique spherical design creates a “wiping” effect during mating, maintaining a debris-free, low-resistance contact surface.
- Minimized Wear: Ideally suited for horizontal and rotational connections, effectively reducing friction and material degradation at the interface between the plunger and mating pad.
CTP Advanced Magnetic Spring-Loaded Connectors
When speed, precision, and enduring durability matter, CTP’s magnetic spring-loaded connectors deliver unmatched performance. Designed with intelligent self-alignment and zero-force mating, these magnetic solutions seamlessly simplify connections without the need for tools or visual guesswork in blind-mate environments.
From rapid board-to-board configurations to highly flexible cable assemblies, CTP offers the versatile customization you need to build faster and smarter. Choose from surface mount (SMT), through-hole, or wire termination styles to perfectly align with your hardware design.
Packaged on Tape & Reel for Automated Assembly
To support high-volume manufacturing, CTP offers a wide range of discrete spring-loaded pins packaged on EIA standard tape and reel. Designed for efficiency, these SMD spring pins can be easily handled by modern automated pick-and-place equipment, often fitted with a removable pick-and-place cap for precision positioning.
Large Base Spring-Loaded Pins for Maximum Stability
Dramatically increase your PCB soldering stability with CTP’s discrete spring-loaded contacts featuring an expanded base design. Engineered to resist lateral forces, these robust contacts provide a secure anchor to the board.
Our large base families offer a versatile range of working heights from .137″ to .430″ (3.48mm to 10.92mm), all built upon a solid .159″ (4.00mm) diameter base for superior mechanical retention.
Rugged, High-Current Spring-Loaded Pins
When power delivery is critical, CTP’s rugged spring-loaded pins rise to the challenge. Expertly machined for extreme environments, these heavy-duty contacts are capable of safely carrying 9 amps of continuous current with a remarkably low 30°C temperature rise.
Deploy our high-current spring probes in demanding applications that require robust, low-resistance power and ground connections without thermal degradation.
Precision Insulated Spring Probes
Standard contacts often fall short when your interconnect needs to breach conductive enclosures or maintain strict isolation from adjacent circuitry. CTP resolves this with our specially engineered insulated spring probes. Encased in high-performance dielectric sleeves, these pins establish a failsafe barrier against short circuits while preserving pristine signal transmission.
They are the ultimate, field-tested choice for safeguarding dense, high-stakes electrical routing.
Engineered Spring Force Configurations
Achieving the perfect mating pressure is essential for interconnect stability. While the majority of CTP’s spring contacts are precisely calibrated to deliver a baseline 60-gram force at mid-stroke, we understand that every hardware application behaves differently.
Whether your rugged design dictates a significantly higher retention force or a gentler touch for delicate components, our expansive inventory likely holds the exact spring profile you need. If a standard option doesn’t fit, our mechanical engineering team is on standby to rapidly develop a custom spring solution tailored to your exact travel and force specifications.
Low-Profile Horizontal Interconnects
Navigating tight vertical space constraints? CTP’s horizontal-mount spring-loaded contacts are explicitly engineered for right-angle and parallel board-to-board mating scenarios. We supply these low-profile interconnects in both surface mount (SMT) and through-hole configurations, featuring industry-standard pitches of .050” (1.27mm) and .100” (2.54mm).
For ultra-sleek spatial requirements, our specialized assemblies with removable isolating carriers offer the absolute lowest mounting profile on the market.
High-Reliability Wire Termination Pins
CTP extends high-reliability connectivity from the PCB directly to your cabling. Our wire-termination spring probes are meticulously crafted for robust cable integration, featuring specialized solder cups for fine signal wires (up to 24 AWG) and heavy-duty crimp barrels for high-power lines (up to 16 AWG).
To streamline your manufacturing workflow, we also provide comprehensive cable assembly services—delivering spring-loaded connectors that are pre-crimped, rigorously tested, and ready for immediate deployment.
Dual-Plunger Spring-Loaded Contacts
Designing complex stacked PCB architectures? CTP’s dual-plunger spring pins act as the perfect electromechanical bridge, delivering active compliance on both ends of the contact. This unique double-action mechanism guarantees an uninterrupted, highly stable electrical pathway between parallel boards.
When thermal profiles or stringent assembly rules prohibit traditional soldering, our compression-mount connector arrays leverage these exact dual-action probes to create highly reliable, completely solderless interconnects.
Hybrid Power & Signal Connector Arrays
Consolidate your board layouts by integrating both power delivery and high-speed data transmission into a single housing. CTP engineers custom connector arrays that smartly combine spring pins of varying working heights and travel strokes within the exact same dielectric insulator.
This hybrid approach is essential for establishing First-Mate/Last-Break (FMLB) sequencing, completely safeguarding your sensitive electronics during hot-swappable operations. Consult our technical team to configure the exact power-to-signal ratio your dynamic module demands.
