856A4624G03 is a high-reliability aerospace vibration sensor, engineered to AS9100D aerospace quality standards and RTCA DO-160G environmental requirements, specifically designed for monitoring rotating components in GE CFM56-7B and LEAP-1B engines on Boeing 737 Next Generation and MAX aircraft.

Constructed from Inconel 625 alloy with a hermetically sealed IP68 housing, it delivers a 0–50 g acceleration measurement range with ±0.1 g accuracy and a 0–10 kHz frequency response, paired with a 4–20 mA analog output for real-time data transmission. Weighing 0.28 kg and measuring 75mm×40mm×28mm, it operates at -55°C to 150°C with a 20,000-hour MTBF. Compliant with FAA Part 33 and EASA CS-E regulations, this sensor detects abnormal engine vibrations to prevent component failure, critical for enhancing propulsion system safety and reducing MRO downtime for narrow-body fleets.
