956A7646G02 is a high-reliability avionics signal isolator, engineered to AS9100D quality standards and RTCA DO-160G environmental specifications, optimized for narrow-body aircraft such as the Boeing 737 MAX and Airbus A320neo during avionics system upgrades and MRO.

Housed in an EMI-shielded, IP67-sealed aluminum alloy enclosure, it electrically isolates analog (4–20mA, 0–10V) and digital signals between avionics subsystems—including engine sensors, flight controls, and navigation units—with ±0.08% signal accuracy and <1μs propagation delay. It features redundant power inputs, wide-temperature compensation (-55°C to 125°C), and surge protection (up to 1000V). Weighing 0.75kg and measuring 95mm×68mm×35mm, it complies with FAA Part 25/EASA CS-25, eliminating cross-signal interference, reducing diagnostic errors, and enhancing avionics system stability for commercial airline fleets.
