SC02A is a capacitive touch sensor with self-tuning, which can detect whether two sensing disks are touched. It can pass through any non-conductive medium (e.gGlass and plastic) to sense capacitance changes. This kind of capacitive induction switch can be used in many electronic products to improve the added value of products.Features:◇ 2 completely independent touch sensitive keys◇ keep automatic correction without external intervention◇ the key output is completely shaken◇ parallel one-to-one output◇ all keys share a sensitivity capacitance◇ different length of induction line will not lead to different sensitivity◇ 2.5V ~ 6.0V working voltage◇ environmental protection sop8 package in accordance with ROHS directiveApplication:1.Replace mechanical switch2.Home application (TV, monitor, keyboard)3.Human machine interface of toys and interactive games4.Access control button5.Lamp control switch6.Sealing keyboard panel
