Vibration Sensor

The vibration sensor VS1 is ideally suited for detecting small oscillations and vibrations. The well-known principle of ball switch gave birth to this component. Here, it is miniaturised to the size of a TOPLED and integrated within a hermetically sealed package. A 0.8 mm high-grade steel ball is set within a small tube with 1mm diameter tube. The wall and base of the tube constitute two contacts that are bridged by the ball when in the quiescent state. With the smallest movement, the contact is briefly interrupted and detected. The sensor is suitable for the qualitative measurement of any vibration or shaking.
