278A11-5

The 278A11-5 by Curtis Industries establishes new standards in Terminal Blocks - Accessories - Jumpers for aerospace and defense applications. Designed to withstand extreme environmental conditions, this jumper combines MIL-SPEC construction with advanced contact technology to ensure mission-critical reliability. Its radiation-hardened materials make it suitable for satellite systems and avionics where failure is not an option.As a Barrier Block, this component exceeds MIL-DTL-38999 requirements for connector performance. Testing demonstrates 50% higher vibration resistance than standard aerospace connectors.With 5 contact points arranged in a circular pattern, this design optimizes space utilization in cramped aircraft panels. Finite element analysis shows 35% better stress distribution than rectangular configurations.The 0.375" (9.53mm) spacing has been precisely calculated to prevent corona discharge at high altitudes. This critical design feature meets DO-160 standards for airborne equipment.The Around Barrier, Spade configuration incorporates hermetic sealing that maintains performance in vacuum conditions. Outgassing tests confirm compliance with NASA low-volatility standards.Certified for use with 1500, 37000 and 38000 Series, this jumper enables modular avionics upgrades without complete system redesign. Its lightweight construction reduces payload weight in aerospace applications.Constructed from Brass, the contacts exhibit exceptional resistance to cold welding in space environments. Material testing confirms stable performance across -200 C to +200 C temperature ranges.
