956A1254G02 is a high-performance aerospace avionics relay, engineered to AS9100D quality standards and RTCA DO-160G environmental specifications, tailored for power distribution in Airbus A320neo and Boeing 737 MAX flight control systems during MRO and line maintenance operations.

Constructed from hermetically sealed nickel-plated copper alloy with a ceramic insulator core, it operates at 28V DC with a 50A switching capacity and a 10ms response time, compatible with 18–22 AWG aerospace wiring. The relay features a redundant coil design for fault tolerance, an IP67-rated enclosure, and a mechanical life of 10⁶ operations. Weighing 0.18 kg and measuring 65mm×45mm×30mm, it functions at -55°C to 125°C and complies with FAA Part 25 and EASA CS-25 regulations. Critical for reliable power switching in flight control and navigation systems, it ensures uninterrupted operation of avionics in commercial narrow-body fleets.
