What precautions for soldering solder cup type J30JY?

Avoid insulator overheating: Pin pitch is only 1.27mm. Soldering dwell time per pin should not exceed 3 seconds. Long exposure to high heat may deform the plastic insulator base. Prevent short circuits: Cover each solder joint with micro heat shrink tubing after soldering to avoid shorting or air breakdown between adjacent pins.

What is the waterproof and salt spray performance of J30JY?

Salt spray: Standard nickel-plated aluminum housing passes 48~96 hours salt spray test. For offshore high-salt environments, stainless steel housing (J30JY-S) or cadmium conversion coating (suffix G) delivers over 500 hours of salt spray resistance. Water resistance: The mated standard version is splash-proof. IP67/IP68 underwater use requires hermetic glass-sealed type or a special external sealing backshell.

Key features

Twist Pin contact: Adopts an industry-leading elastic twist pin design with multi-point contact, ensuring continuous power supply under severe vibration and shock.

Low contact resistance: Contact resistance as low as 10 milliohms, ensuring superior signal integrity and low transmission loss.

High insulation & voltage resistance: Insulation resistance up to 5000 megaohms, with a dielectric withstand voltage up to 800V, effectively preventing high-voltage breakdown.

Outstanding vibration & shock resistance: Engineered for high acceleration and high-frequency vibration environments, complying with aerospace high-reliability standards.

Great salt spray resistance: The shell is specially surface-treated (nickel plating or passivation) for strong anti-corrosion and salt spray protection.

Fine pitch design: 1.27mm contact pitch, integrating more pins within limited space to save internal equipment volume.

Lightweight metal shell: High-strength aluminum alloy or stainless steel housing, maintaining mechanical strength while reducing component weight.

Multiple pin count options: Available in 9,15,21,25,31,37,51 pins and other common configurations.

Diverse termination styles: Crimp, solder, straight PCB mount, and other rear termination types to fit various assembly processes.

AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company with a business scope covering electronic components, power electronics, electromechanical equipment, industrial control computers, industrial robots, software development, and related technical services. It reports customization capabilities across samples, designs, full customization, minor customization, and flexible customization, and states that new products were developed in the past year. Service procedures, corrective and preventive action procedures, and customer complaint-handling procedures are documented and supported by records. The supplier states that it serves over 50,000 clients worldwide, including OEMs, ODMs, EMS providers, and SMEs. However, no certification information or direct production-capacity evidence is provided. Financial records shown in the slices contain zero values across multiple indicators, so financial credibility cannot be positively established from the available information.

Supplier typeThe supplier is explicitly classified as a trading company. Its stated business scope includes electronic-component sales and manufacturing-related activities, industrial control systems, industrial robots, software development, and technical services, indicating a broad electronics and industrial technology focus.

After-Sales capabilityThe supplier reports written procedures and followed records for service-capability assessment, corrective and preventive actions, and customer complaint handling. It also states service quotation and payment terms and lead times of within 15 working days in both peak and off-season, but the evidence does not specifically describe warranty, repair, replacement, or technical support coverage after delivery.

R&D capabilityThe supplier reports R&D capability with new products developed during the past year. Its registered business scope also includes research and development of engineering and technology, software development, industrial internet data services, and technical development activities, providing explicit evidence of innovation-related capability.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, customization from designs, minor customization, and flexible customization. These stated service categories directly support a broad customization capability.

Client casesThe supplier states that it serves over 50,000 clients worldwide, including OEMs, ODMs, EMS providers, and small and medium-sized enterprises. This indicates broad customer exposure, although no named customers, project descriptions, or independently verifiable case studies are provided.

Product Q&A

Q:Is the sample price shown on the page the final price?

The listed sample price is for reference only. Final sample & bulk price depends on your specific requirements, including PCB layers, surface finish, BOM components, quantity, testing standards and turnkey service. Please send Gerber files, BOM and specs for an accurate quotation.

Q:Is real-time order tracking available?

Yes. Our self-developed system supports one-click order submission, real-time progress tracking and 24/7 workshop live streaming for full visibility.

Q:What after-sales services can I get?

We provide 24/7 dedicated customer service and a formal warranty for turnkey orders. Free rework will be offered if defects are caused by our production process.

Q:Can J30JY mate with J30J, MDM or Micro-D connectors from other brands?

Yes. J30JY shares identical outline dimensions, pin layout, and core parameters with the standard J30J, MIL-DTL-83513, and the common MDM series. Direct mating and replacement are supported.

Q:Can J30JY support blind mating or floating PCB mounting?

Standard J30JY adopts a fixed locking structure. If blind mating is required, please specify during purchase. A modified housing with guide pins/sleeves for floating mounting is available to compensate for alignment deviation.
