The Dytran model 3333A1 is considered a smaller IEPE triaxial accelerometer having a low-end frequency response of about 0.31 Hz which is ideal for response at low frequencies. It contains units that weigh just 2.3 grams. It has a vertical height of 0.32 inches (8.1 millimeters) and it features a quality signal-to-noise ratio. Its distinguished feature includes a Dytran-designed 4-pin radial connector. Compared to the industry standard connector (1/4-28 thread size), the device integrates a M4.5x0.35 connector that is approximately 20% smaller. This consequential difference in size allows more flexible, smaller diameter, lightweight cable connector. It adds to the over-all small size of the accelerometer. Other features include a ceramic shear sensing elements combined with an ultra-low noise JFET package.
