Key Features & Advantage

Dual Space Optimization: Combining a 90-degree right-angle layout with "Short Latch" mechanical ejectors, this header minimizes both vertical height clearance and horizontal footprint when the latches are ejected, making it perfect for shallow housing.
Vibration-Proof Mechanical Security: Despite its compact size, the short ejector latches clasp the mating IDC ribbon cable connector securely, preventing connection drop-outs in highly turbulent or high-vibration industrial applications.
Easy Integrated Cable Ejection: Features built-in micro levers that roll smoothly outward to lift out the header cable plug, allowing hassle-free system maintenance without tearing or stressing delicate ribbon wire cores.
Fool-Proof Centered Keyway: Designed with standard central polarization slots and side insertion guides to enforce correct alignment and 100% eradicate the risk of inverted mating mistakes.
Industrial Wave-Soldering Robustness: Molded with premium UL 94V-0 high-performance engineering plastics (LCP/NL6T options), the frame guarantees perfect structural shape retention and coplanarity during industrial wave-soldering lines.

Classic Applications

Low-Profile Industrial Computing: Ideal for edge computing controllers, embedded PC/104 boards, and small-footprint programmable logic controller (PLC) modules where vertical headspace is restricted.
Compact Telecommunications & Routers: Used for parallel daughter-card bus systems inside slim 1U rack servers, slim telecom gateways, and network switch sub-boards.
Handheld & Portable Medical Diagnostics: Excellent for internal flat ribbon cabling within portable ultrasound units, field patient monitors, and point-of-care testing (POCT) devices.
Automotive Dashboards & Telematics: Compact central display hubs, smart EV charger control boxes, and sub-system power routing requiring low-height and high vibration resistance.
Space-Constrained Smart Appliances: Low-profile access control master boards, commercial ticketing kiosk electronics, and smart grid automation terminals.
