Energy saving aspects of products (‚green products‘) get more and more important. A common method to achieve this is to put the system in a low power state while the system is not used (sleep mode) and to wake up the system as soon as it is moved. Normally a sensor is needed to switch from sleep mode to normal operation. Our VS1 and VS2 are perfectly suited to detect movements of handheld devices and to trigger the wake up of the system.
Endrich provides these surface mountable micro vibration sensors VS as a replacement of a mercury switch. The sensors detect vibrations by bridging a high ohmic gap in a P.C.B. witha micro ball (ø 0.8 mm). During vibration the resistance between both contact areas changes from some MΩ to less than 100Ω. Compared to VS1 type, VS2 has contacts on both sides (top and bottom) of the cylindric tube, whereas VS1 only has only one contact at the bottom side. Therefore VS2 has nearly omnidirectional sensitivity characteristics.
