Key Features & Advantage

Space-Saving Right Angle Design: The right-angle orientation allows the mating cable to be plugged parallel to the PCB surface, significantly lowering the overall vertical height profile for slim or stacked chassis designs.
Secure Long Latch Locking System: Equipped with rugged long mechanical ejector latches that tightly lock the matching IDC socket in place, offering superior pull-out resistance under shock and high-vibration environments.
Smooth Mechanical Ejection Mechanism: The heavy-duty levers roll outward to seamlessly eject the cable connector, ensuring quick maintenance and minimizing stress or damage to wires and contact pins.
Standard Keyway Polarization: Features a standard central polarization slot combined with lateral guides to ensure error-free mating alignment and prevent inverted insertion.

Classic Applications

Industrial Automation & Robotics: Ideal for linking multi-axis motion controller boards to moving robotic arms via IDC wire harnesses, where constant movement demands non-disconnectable locking.

Aerospace & Defence Electronics: Used in navigation computers and armored vehicle control cabins where extreme vibration, continuous g-force, and thermal fluctuations are common.

High-End Telecommunication Servers: Horizontal server blades, multi-channel processing arrays, and rack-mount routers where board spacing is highly limited.

Heavy Medical Diagnostics: Critical link boards inside high-vibration equipment such as mobile X-ray units and specialized lab centrifuges.

Renewable Energy Storage & Inverters: Connecting the master control units to battery monitoring ribbon cable bundles in solar grid inverters and electric vehicle charging pillars.
