CTP is a premier, engineering-driven manufacturer specializing in high-precision magnetic pogo pin interconnect mechanisms. Our 2-Pin Magnetic DC Power Connector Set delivers robust, zero-force mating tailored for modern low-profile and high-current hardware configurations.
Engineered with customized permanent magnets and intelligent polarization architecture, this system supports accurate self-alignment, foolproof directional coupling (Poka-Yoke), and comprehensive dual-circuit polarity safety protection. Compared to traditional barrel jacks, CTP’s magnetic solution ensures exceptional longevity, safe breakaway capabilities, and reliable power transmission.
Supports up to 12V 5A fast-charging ratings on the interconnect interface, engineered specifically for controlled voltage-drop performance.
Rigorously tested to withstand 20,000+ continuous mating cycles while maintaining stable contact resistance.
Utilizes premium NdFeB permanent rare-earth magnets to automatically guide docking and block incorrect reverse pairing.

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.
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.
Yes. Customization can cover geometry, contact layout, materials, cable construction, magnetic structure, sealing and appearance. Feasibility depends on the application and approved specification.
No. Current, voltage, resistance, temperature rise and ingress-protection claims apply only to the identified model and stated test conditions.
Timing is confirmed after the drawing, materials, tooling, sample quantity, validation scope and production requirements have been reviewed.
ENGINEERING CONFIRMATION BEFORE SAMPLING
Confirm power, signal and grounding allocation for the intended device.
Confirm working stroke, alignment, mounting, retention and mating behavior.
Confirm cable exit, host interface and project-specific assembly requirements.
Use the approved drawing and agreed validation plan as the release reference.
Submit your Pin Map, electrical requirements, available space, mating structure and project quantity for connector selection or custom development review.
Use the following engineering guides to compare contact count, contact allocation and connector layout before confirming the final product or customized design.
