Key Features & Advantage:

Deep 7.4mm Insulator Housing: The 7.40mm extended plastic body acts as a powerful structural spacer, accommodating taller passive components (like power capacitors and inductors) near the board edge without risking physical interference or electrical shorts.
Dual-Row High-Capacity Interconnect: Utilizes a standard 2.54mm grid to deliver dense multi-channel power and signal configurations through a singular, reinforced edge terminal.
Rugged Through-Hole Anchor: DIP pin terminations insert deeply into the PCB, establishing long-lasting solder joints capable of handling high leverage, heavy plugging forces, and excessive side-pull tension.
High Thermal Endurance & Finish Options: Injection molded from standard-compliant, reflow-capable LCP or NL6T engineering plastics (UL 94V-0). Plating can be fully customized (Gold Flash, Gold 3U", or selective Plating Tin) to match strict lifespan requirements.
Seamless ELETE Socket Pairing: Universally matches ELETE's double-row female receptacle lines, including HFNDSH8YP, HFNDS68, HFNDM8Y, HFNDM11, HFNDM71, HFNDT71, HFNDR8Y, and HFNDR8T.

Classic Applications

This extra-deep, right-angle double-row pin header is the ideal solution for heavy-duty electronic systems requiring maximum hardware clearance and absolute rigid enforcement at 90-degree board boundaries:

Industrial Power Systems: Main inverter control chassis, modular high-power switching power supplies, and industrial rectifier board stacks.
Heavy Machinery & PLC Equipment: Modular rack-mount controllers, robotic control enclosures, and motor drive interfaces where tall components reside near the connection plane.
Energy Storage & EV Infrastructure: Battery management system (BMS) master/slave board connections and commercial EV charging station routing panels.
Telecommunications Backplanes: High-clearance interface routing inside enterprise network servers, telecom outdoor base stations, and rugged line cards.
Medical Diagnostic Platforms: Right-angle motherboard assembly inside imaging systems, patient ventilators, and heavy-duty laboratory testing hardware.
