J14 Series Rectangular Connector

The J14 series rectangular connectors (comprising J14A, J14B, and J14F) feature a compact, lightweight build with a rounded anti-mismating design and mounting hole distances ranging from 14.5mm to 58mm. They provide reliable internal electrical signal connections for aerospace, maritime, and electronic instruments.

Each sub-series is tailored for specific technical requirements. The J14A offers a double-safety locking mechanism and diverse termination styles. The J14B upgrades this with rainproof capabilities and higher contact density. The J14F provides a high-density, push-pull solution with pre-wired terminations.

WHY J14 SERIES

Where J14 Series connectors are deployed, with recommended sub-series.

Internal Signal Routing: Facilitating reliable low-frequency electrical signal connections between internal circuit boards and modular components within enclosed equipment cabins.
Environmental Isolation: Providing rainproof and sealed panel interfaces (like the J14B) for equipment exposed to moisture or harsh maritime conditions.

High-Density Space Optimization: Utilizing compact and push-pull designs (like the J14F) to maximize pin density in space-constrained avionics or rugged servers.
Vibration-Resistant Transmission: Ensuring stable data and power transfer in high-vibration environments (e.g., flight controllers, industrial robotics) via double-safety locking mechanisms.
