Murata PKGS series of vibration sensors, both ends of the device can detect acceleration and impact as electrical signals.
These vibration sensors use dual-polarized piezoelectric elements, which are fixed at one end (cantilever structure) by original polarization technology, with high sensitivity and excellent durability. The vibration sensor is a reflow solderable SMD type. They can have tilted spindles, so you can choose the right vibration sensor to detect vibrations in HDDs (hard disk drives) and choose optical pickup controls in optical drives and magneto-optical drives.
