Can J30J be used in airborne or aerospace equipment?

Yes, rugged mechanical design fits airborne, aerospace, and test measurement systems.

What are the differences among signal type, mixed high-low current type and power type J30J?

They share the same shell outline. The difference lies in the contact layout and rated current: Standard signal type: all contacts for low-current signal transmission. Mixed high-low current type: mixed small-signal pins and large power pins in one housing. Power type: all heavy-current contacts dedicated to power transmission.

Are both male and female connectors available?

Yes, plug and receptacle are available as mating pairs.

Key features

High-density micro rectangular connector: small pin pitch, many contacts within a tiny metal housing. Fits limited-space electronics like avionics and test modules.

Rugged shell structure, excellent shock and vibration resistance. Metal alloy shell with reinforced locking design. Keeps contact continuity under constant vibration and mechanical impact.

Wide operating temperature range: Works stably from -55 degrees Celsius up to +125degrees Celsius, handles extreme cold and high heat inside airborne or field devices.

Compact size; saves installation space. Much smaller than standard rectangular connectors. Helps shrink the overall size of your control or power unit.

Quick-locking mechanism for reliable mating & unmating. Built-in snap lock. After plugging in, it locks automatically; release to unlock. Prevents accidental disconnection.

Good shielding performance; suppresses electromagnetic interference. The seam metal shell forms a shielding enclosure. Blocks external EMI and stops internal signal noise from leaking out.

High contact reliability for long service life. Gold-plated contact surface. Low contact resistance, stable signal/power transmission even after hundreds of mating cycles.

Crimp-contact style, convenient wire harness assembly. No soldering required. Crimp wires onto separate pins first, then insert the pins into the connector housing for harness production.

Product performance meets GJB2446 requirements, equivalent to US MIL standard MIL-DTL-83513.

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.
