Overview: 

The SC09B is a self-correcting capacitive sensor that detects whether or not the 9 sense discs have been touched. It can sense capacitive changes through any non-conductive medium such as glass and plastic. This capacitive switch can be used in many electronic products to increase the added value of the product.
