Three-axis measurement
YD37 measures X, Y and Z simultaneously using built-in IEPE preamplification. The sensor uses a shear structure, PZT-5 piezoelectric material and a 304 stainless-steel housing. Its stated output connector is a four-pin 1/4–28 type.
The listed peak ranges are ±500 g, ±100 g and ±50 g. Corresponding sensitivities are presented in the same order as 10, 50 and 100 mV/g, with ±5% sensitivity tolerance at 25 °C and a 160 Hz reference. Confirm the ordered range/sensitivity pair from its calibration information.

Mounting and cable
The source lists M5 mounting or adhesive attachment and supplies an M5 mounting bolt. The listed cable is a 2 m shielded cable from the four-pin 1/4–28 plug to three BNC connectors.
Use the supplied axis markings and connector drawing to identify the X/Y/Z channels. The source's dimension, temperature-response and frequency-response plots are graphical; this article does not invent connector pin positions or plot coordinates.
