Micro Vibration Sensor

Short description
The micro vibration sensor records motion and vibrations through a gold-plated, moving micro-ball. Together with application-specific electronics for signal evaluation, this sensor controls the operational status of motion sensitive equipment. Due to its small size, the sensor is suitable for use in very small electronic devices.

Operation
A micro-ball with a diameter of just 0.8mm is located in a hollow of the sensor and can move freely inside this hollow. Even the smallest movement or vibration causes the ball to move so that this one closes or opens two gold-plated contacts. The pulses resulting from this are evaluated by application-specific electronics and are implemented in corresponding switching signals.

Advantages
Intelligent energy-saving:
As soon as the sensor detects no more movement, the electronics switch to the power-down mode after an application-specific time delay. Saving energy made easy.

Tiny and multitalented:
Thanks to minimum dimensions (miniaturisation) there are almost no limits to the application of the micro vibration sensors.

Economical:
A patented manufacturing technique enables the mass production of the sensors in large quantities on the basis of printed circuit boards - and that means consistent high quality and with high efficiency.

Environmentally friendly:
Unlike previously used mercury switches, the micro vibration sensor by Sensolute forgoes environmentally damaging, toxic substances and therefore is RoHS and REACH compliant. Halogen free Micro Vibration Sensors are also available.

Applications

Our sensors are suitable for a wide range of applications.

Together with electronics for signal evaluation, they control the operational status of motion-sensitive equipment.

Bicycle lights, which turn on when it is dark and the bicycle is moving; LCD remote controls which switch off when inactive or RFID systems which facilitate the monitoring and locating of objects or living things – in short: wherever something moves, Sensolute energy saving sensors come into play:

• bicycle computers
• active RFID systems
• GPS tracking systems
• access control systems 
• hands free sets, car kits
• illuminated dog’s collars
• security systems
• patient monitoring
• data loggers
• remote controls with LCD displays
• shavers with LCD displays
• bicycle lights
