Vibration Sensor VS1 and VS2

Energy saving aspects of products (‚green products‘)
got more and more important. A common method to achieve
this, is to put the system in a low power state as long as the
system is not used (sleep mode) and to wake up the system as
soon as it is used. 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. with
a 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 a contact
at the bottom side. Therefore VS2 has nearly omnidirectional
sensitivity characteristics.
