J14B-26TJ J14B-26TJ

J14B-26TJ is a military-grade rectangular miniature D-sub connector (Micro-D style design), configured as a male plug featuring 26 highly dense contacts (pins) arranged in 3 parallel rows. This part is designed as a wire-leaded cable mount connector (pigtail type), typically equipped with a factory-terminated 1-meter cable bundle (or customized wire leads) encased inside a ruggedized strain-relief shell assembly. The interface mating contact pitch is exactly 1.27 mm.

The electrical and environmental specifications of this connector include a rated current of 2 A per contact, a maximum contact resistance of 10 mΩ (initial phase prior to mechanical aging tests), an insulation resistance exceeding 1000 MΩ under standard atmospheric conditions (and over 80 MΩ under extreme high temperature), and a dielectric withstanding voltage of 800 V AC.

The connector housing is fabricated from a premium aluminum alloy shield and comes equipped with a push-pull double safety locking mechanism alongside anti-mismating keying provisions to ensure absolute connection reliability under high-vibration scenarios. This component is optimized to reliably operate within an extended temperature envelope ranging from -55°C up to +125°C, withstand low-pressure atmospheric conditions from 101.3 kPa down to 1.33 Pa, and endure a relative humidity of 90% to 95% at a temperature of 40°C, making it fully certified for critical aerospace, avionics, and deep-submersible electronic applications.
