Overview: 

The SC09A is a self-correcting capacitive sensor that detects whether or not the 9 sensing 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.

Features:

◇ 9 completely independent touch-sensitive buttons.

◇ Maintains automatic correction without external intervention.

◇ Key outputs are completely de-vibrated.

◇ I2C serial interface.

◇ All keys share the same sensitivity capacitor.

◇ Differences in the length of the inductor wire will not cause differences in sensitivity.

◇ 2.5V ~ 6.0V working voltage.

◇ Eco-friendly SOP16 package compliant with RoHS directive.

Applications.

◇Replacement of mechanical switch.

◇Home applications (TV, monitor keyboard).

◇ Human-machine interface for toys and interactive games.

◇ Keypad for access control.

◇ Light control switches.

◇ Sealed Keyboard Panel.
