Model 3403A Triaxial Accelerometer

Product Announcement from Dytran Instruments, Inc.

The Dytran model 3403A is a miniature triaxial accelerometer that weighs just 4 grams and has a vertical height of 0.32 inches (8.0 millimeters).

The distinguishing characteristic of model 3403A is its exclusive, Dytran designed 4-pin radial connector. Compared to the industry standard connector (1/4-28 thread size), the model 3403A incorporates a M4.5 x 0.35 connector that is approximately 20% smaller in size. This substantial size difference allows for a more flexible, lightweight cable, a smaller diameter for the connector, and also contributes to the overall small size of the accelerometer.

Available with a sensitivity of 10 mV/g, the Dytran model 3403A features quartz shear sensing elements packaged in a robust laser welded titanium housing with adhesive mounting capabilities. Units are hermetically sealed for reliable operation in high humidity and dirty environments and case isolated to avoid EMI/ground loop interference.
