Overview: 

The SC12B is a self-calibrating capacitive touch sensor that detects whether or not the 12 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.
