※1 Representative value; actual value is noted on calibration sheet supplied with accelerometer.

※2 Representative value when mounted on flat surface according to standard mounting method (※4)

※3 The maximum measurable acceleration differs, depending on temperature, voltage sensitivity, and power supply voltage.

● The internal chip and piezoelectric element in a piezoelectric accelerometer may be damaged by excessive shock. Take care not to drop the accelerometer, and handle it with care when using the
magnetic attachment
