This advanced interconnect solution delivers exceptional signal integrity while meeting stringent industrial standards. With its versatile configuration options, it provides design engineers with unparalleled flexibility in 5G infrastructure and industrial automation systems.Featuring Plug, Female Sockets construction, this component ensures reliable mating cycles exceeding 10,000 insertions. The precision-engineered interface minimizes insertion loss while maintaining impedance matching for high-frequency applications.Available in 11 (Mate), 22 (Input) positions, the modular design allows scalable configurations for power distribution systems. Compared to conventional blocks, it offers 30% higher contact density without compromising current handling capacity.With 11 (Mate), 22 (Input) positions per level, the optimized layout reduces crosstalk between adjacent channels. This architecture is particularly beneficial in dense PCB layouts where space constraints are critical.The 1 (Mate), 2 (Input) level configuration provides design engineers with multiple stacking options. When deployed in hybrid arrangements, it enables three-dimensional routing solutions for complex control systems.The 0.295" (7.50mm) pitch spacing complies with international safety standards while accommodating high-voltage isolation requirements. This carefully calibrated dimension prevents arc-over in power electronics applications.180° wire entry angles facilitate efficient cable management in confined spaces. The multi-directional design simplifies maintenance operations in industrial control panels.Utilizing Screwless - Leg Spring, Push-In Spring termination, the connection system achieves vibration-resistant joints with minimal contact resistance. Field tests demonstrate 50% faster installation time compared to screw-type alternatives.The Free Hanging (In-Line) mounting option provides secure mechanical attachment in high-vibration environments. This ruggedized solution meets MIL-STD-202G specifications for shock and impact resistance.Meeting 16A IEC standards, the current-carrying components utilize oxygen-free copper alloys. This material choice minimizes thermal derating in continuous operation scenarios.The 1 kV IEC voltage certification covers both AC and DC applications. Third-party testing verifies clearance and creepage distances exceed category III requirements.Rated for 20 A UL current, the contacts employ proprietary alloy compositions for stable performance under load. Continuous operation testing confirms less than 1% resistance drift after 5,000 thermal cycles.With 600 V UL voltage rating, the insulation system exceeds IPC-2221B requirements. The dielectric material formulation prevents tracking and carbonization in humid conditions.Compatible with 12-24 AWG wire sizes, the termination system maintains consistent clamping force across the entire range. This eliminates the need for special tools when working with mixed gauge installations.The Gray housing incorporates UV-stabilized polymers for long-term color retention. Visual indicators enhance error-proofing during assembly line installations.Operating across -60°C ~ 85°C range, the materials selection ensures stable mechanical properties in extreme conditions. Thermal modeling confirms reliable performance from arctic to desert environments.Tin plating delivers optimal balance between cost and performance. The surface treatment achieves 100 contact resistance after salt spray testing per ASTM B117.The Lever Actuated, Retention Latches (Non-Wire Side) design elements address common field failure modes in transportation applications. These include patented anti-vibration mechanisms and dust-resistant cavity designs.
