Description
Premium 39 Pin High Density Pogo Pin Custom Solutions
CTP’s premium 39 pin high density pogo pin module is explicitly developed for industrial, testing, and medical-grade equipment requiring massive multi-channel data concurrent transmission and complex signal control. On a long-row high-molecular plastic housing, this connector integrates up to 39 high-precision independent spring probes, supporting 1A/5V DC standard transmission per channel. By converging 39 independent contacts onto a single physical interface, it drastically simplifies wire harness routing and external port designs for large-scale hardware systems.
Unmatched Coplanarity Control & Advanced Mechanical Engineering
The primary technical bottleneck for extra-long multi-pin connectors has always been coplanarity[cite: 2]. Backed by advanced mold manufacturing and automated CCD visual inspection systems, CTP strictly restrains the coplanarity tolerance of all 39 pin heads to ≤0.1mm. This eliminates the common industry pain point of poor contact at the ends or floating pins in the middle, guaranteeing 100% zero-omission synchronized conduction upon mating.
Furthermore, compressing 39 spring pins simultaneously generates a substantial total reaction force of around 2.3kg[cite: 2]. To address this, our engineering team has meticulously calibrated the single-pin spring force to a gentle 60g±15g. While maintaining an ultra-low contact resistance of ≤ 30 mΩ for zero-attenuation high-frequency signal integrity, it minimizes the required overall engagement force, facilitating a perfect lock when paired with mechanical levers or housing fasteners.
Industrial Durability & Reflow Soldering Stability
Long-row plastic housings are highly vulnerable to bending and warping during high-temperature SMT reflow processes[cite: 2]. This custom module adopts premium high-temperature LCP plastic (UL94V-0 flame retardant grade) processed through a specialized injection molding stress-relief technique, ensuring a perfectly straight and unwarped structure even after wave or reflow soldering. Utilizing premium high-fatigue imported spring steel and a brass base with a 5μ” gold-plated finish, it delivers an extended mechanical life of 50,000 cycles with minimal wear. It operates seamlessly under industrial extreme temperatures ranging from -40°C to +85°C and withstands severe industrial environments with a vibration rating of 10-55Hz at 1.5mm amplitude, keeping transient disconnections under ≤ 1μs[cite: 2].

Frequently Asked Questions (FAQ)
How does this 39-pin connector prevent incomplete contact across its long row?
The technical challenge of extra-long connectors is maintaining flat alignment[cite: 2]. CTP controls coplanarity to ≤0.1mm via high-precision molds and automated CCD visual inspection. This guarantees that all 39 pins achieve simultaneous, uniform physical contact, completely eliminating middle-floating or edge-虛接 issues.
Is the mechanical pressing force manageable for a 39-pin layout?
Yes. Compressing 39 pins simultaneously generates a total counterforce of approximately 2.3kg[cite: 2]. Our engineering team has optimized the single-pin force to a balanced 60g±15g. This safely minimizes the overall force required to engage the connector while still maintaining a stable connection resistance of ≤ 30 mΩ.
What are the primary applications for this high-density multi-channel module?
This 39 pin high density pogo pin module is ideal for semiconductor testing封装 and FCT function fixtures, large medical diagnostic instruments (e.g., ultrasound probes), telecom base station backplanes, server blade chassis board-to-board docking, and heavy transportation or automotive control terminals subjected to strong vibrations[cite: 2, 3].
