The IM727 is a drop-test accelerometer for mobile electronic devices.
The Endevco Model 727 is a family of rugged undamped piezoresistive accelerometers designed for shock measurements in mobile consumer electronic devices. This instruction manual provides technical details specifically for the single-axis accelerometers in the wax mount configuration, including models 727-60K, 727-20K, 727-6K, and 727-2K. The document outlines handling precautions to prevent damage due to resonance excitation and electrostatic discharge (ESD).
