Precision Engineering for Demanding Applications

The 3743G accelerometer incorporates advanced MEMS technology and comes packed with features designed to maximise performance in harsh conditions:

• Exceptional Precision: With excellent linearity and minimal temperature error, the 3743G ensures highly accurate measurement data, critical for both vehicle dynamics analysis and flight testing.
• Differential Output: This feature delivers superior common mode noise rejection, crucial when operating in electrically noisy environments such as engine bays or aircraft fuselages.
• Dual-Mode Operation: The sensor supports both differential and single-ended output modes, providing flexibility for various test setups and simplifying integration.
• Extremely Rugged Design: Built to withstand shocks up to 5,000 g, the 3743G is ideally suited for high-impact scenarios such as rough road simulations or in-flight turbulence.

Two Configurations to Match Your Environment

The PCB Model 3743G is available in two versions to suit different connectivity and environmental requirements:

• 3743G11 – Encased in a hermetically sealed stainless-steel housing with an integrated M8x1 8-pin connector, this model offers robust protection and convenient plug-and-play capability.
• 3743G12 – Features the same rugged housing but includes an IP67-rated integral cable, offering enhanced protection against water, dust, and debris in the most demanding environments.
