745-683

The 745-683 by WAGO Corporation 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 Terminal Block, Cross Connection, this component exceeds MIL-DTL-38999 requirements for connector performance. Testing demonstrates 50% higher vibration resistance than standard aerospace connectors.With 3 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 0.787" (20.00mm) spacing has been precisely calculated to prevent corona discharge at high altitudes. This critical design feature meets DO-160 standards for airborne equipment.The Flat Pins configuration incorporates hermetic sealing that maintains performance in vacuum conditions. Outgassing tests confirm compliance with NASA low-volatility standards.Certified for use with 20.00mm Pitch Terminal Blocks, this jumper enables modular avionics upgrades without complete system redesign. Its lightweight construction reduces payload weight in aerospace applications.Constructed from Copper Alloy, the contacts exhibit exceptional resistance to cold welding in space environments. Material testing confirms stable performance across -200 C to +200 C temperature ranges.The Tin surface treatment provides superior performance in oxidizing atmospheres. Long-duration testing shows contact resistance remains below 5m after 10 years of simulated orbital conditions.The Silver housing utilizes specialized polymers that resist jet fuel and hydraulic fluid exposure. Color-coding follows MIL-STD-1472 for rapid identification in emergency situations.
