Magnetic Pogo Connector FAQ

CTP mainly adopts neodymium iron boron (NdFeB) permanent magnets, which feature strong magnetic force, stable performance and small size. High-grade N35/N52 magnets are optional for different customer requirements.

Yes. The matched magnetic force of CTP magnetic connectors is precisely calibrated for automatic alignment, stable adsorption and anti-drop, adapting to daily frequent docking and vibration scenarios.

Absolutely. CTP supports full magnet customization, including custom magnet shapes (round, square, rectangular, irregular special-shaped magnets) and adjustable magnetic performance. We can tailor magnetic force strength, magnetic pole position and adsorption tolerance according to customer’s product structure and usage scenarios (light adsorption / heavy anti-drop) to match unique assembly requirements.

CTP adopts post-assembly magnetization (full magnetization after molding) and directional pole magnetization technology. It ensures accurate magnetic pole direction, no reverse magnetism, and consistent adsorption effect for each CTP connector.

No. CTP has standardized pole identification and fixture positioning processes to guarantee 100% correct polarity and uniform magnetic force in bulk orders.

Yes. High-temperature welding process will cause temporary demagnetization of NdFeB magnets. CTP adopts a professional secondary re-magnetization process after soldering to fully restore and stabilize the magnetic performance, ensuring consistent adsorption force for finished products.

The magnetization procedure consists of the following steps:

• a. Secure the product after welding.
• b. Place the product into the calibrated magnetizing machine.
• c. Magnetize according to the specifications of the required magnet grade.
• d. Inspect the performance of the magnetized magnets.

Standard working temperature: -20℃ to +80℃. CTP high-temperature resistant versions can support up to 100℃~120℃ without demagnetization, suitable for industrial, automotive and outdoor equipment.

CTP industrial-grade NdFeB magnets have stable temperature resistance. No obvious demagnetization occurs within the rated temperature range, ensuring long-term stable use.

Standard CTP products support 10,000+ plug-in cycles, with stable spring force and continuous conductivity, meeting long-term commercial and industrial use.

Yes. The precise magnetic pole matching design of CTP enables automatic suction, fast alignment and anti-offset docking, greatly improving connection efficiency.

Conventional CTP models support 3A-10A current and 5V-24V voltage. High-current customized versions up to 20A are available.

Standard CTP magnetic pogo connectors achieve IP54 waterproof and dustproof rating, capable of resisting daily splashing water, dust and moisture. Customized waterproof versions up to IP67 are available for outdoor, automotive, industrial and wet environment scenarios, supporting short-term water immersion and fully dustproof performance.

Typically, premature failures are mainly caused by over-compression and side/axial loads. Frequent manual over-compression will deform the internal spring, causing the plunger to fail to return to its original position. Excessive side loads will also lead to plunger binding or sticking. CTP recommends designing a mechanical stop or compression limit on your product structure to protect the pogo pin plunger and avoid abnormal damage.

All CTP products comply with ROHS, REACH environmental standards. Customized industrial versions can support CE/FCC certification application.

The CTP pogo pin surface adopts gold-plated/nickel-plated treatment, and the magnet is encapsulated and insulated, featuring wear resistance, oxidation resistance and long service life.

In most cases our high-reliability electrical connectors can be manufactured from lead-free alloys to meet your application needs while meeting CTP’s stringent standards and industry-leading build quality. CTP is committed to global environmental compliance, manufacturing connectors that align with multiple international sustainability regulations.

Yes, over 95% of CTP magnetic connectors are customized. CTP has over 100,000 customized cases from various industries, including over 100+ well-known industry-leading brands.

Custom product lead times vary depending on the application. Simple customized products normally take 2-3 days, while complex industrial products take 1-2 weeks for design confirmation and 1 month for sample production. CTP launches over 80+ new custom products every week.

Discrete pins, receptacles, and spring-loaded components have a minimum order quantity of 3,000 pcs. For custom connector assemblies, the MOQ is calculated based on at least 3,000 individual contacts in the assembly. For example, an assembly with 10 pins/contacts requires a minimum quantity of 300 pcs. For CTP magnetic series products, including magnetic pogo pins, magnetic modules and magnetic charging cables, the standard MOQ is 1000 pcs.
