Overview : 

SC04A is a capacitive touch sensor with self-calibration that detects if 4 sense discs are touched. It can sense capacitive changes through any non-conductive media such as glass and plastic. This capacitive sensing switch can be used in many electronic products to increase the added value of the product. 

 Features :

◇ 4 completely independent touch-sensitive buttons .

◇Automatic correction is maintained without external intervention.

◇ Key outputs are completely dithered .

◇ Parallel one-to-one output .

◇All keys share the same sensitivity capacitor.

◇Differences in the length of the sensing line will not cause differences in sensitivity.

◇2.5V ~ 6.0V operating voltage .

◇ Eco-friendly SOP16 package compliant with RoHS directive.

 Applications :

◇Replacement of mechanical switches.

◇Replacement of mechanical switches.

◇Home applications (TV, monitor, keyboard).

◇Human-machine interface for toys and interactive games.

◇Access control buttons .

◇Light control switches .

◇ Sealed Keyboard Panels .
