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. 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, supporting 100% zero-omission synchronized conduction upon mating.
Furthermore, compressing 39 spring pins simultaneously generates a substantial total reaction force of around 2.3kg. 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. 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 closely 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.

Engineering Review for Premium 39 Pin High Density Pogo Pin Module | CTP Custom Solution
This product page presents a CTP magnetic connector configuration for engineering reference. Final dimensions, electrical ratings, materials, magnet structure, sealing level and reliability targets are not universal values; they are confirmed against the approved drawing, installation condition and model-specific validation plan.
Information to provide for evaluation
- pin count, pitch, pin map and mating direction
- housing envelope, mounting method and device-side interface
- current, voltage, signal and contact-resistance targets
- magnetic retention, polarity, sealing, materials and finish
- sample quantity, validation plan and forecast volume
How specifications are confirmed
CTP reviews the application and prepares a drawing or specification for approval before sample production. Test scope, acceptance criteria and report format should identify the model, sample status, method, conditions, result and review date.
Can this magnetic connector be customized?
Yes. Customization can cover geometry, contact layout, materials, cable construction, magnetic structure, sealing and appearance. Feasibility depends on the application and approved specification.
Are the electrical and waterproof values universal?
No. Current, voltage, resistance, temperature rise and ingress-protection claims apply only to the identified model and stated test conditions.
What determines sample and production timing?
Timing is confirmed after the drawing, materials, tooling, sample quantity, validation scope and production requirements have been reviewed.
