Flexible, responsive and reliable capacitive touch controls for the new generation of consumer brown and white goods and AV equipment, as well as vending machines, lift controls and security access, can be achieved using the new touch sensor IC family from Omron. Easily connected to any capacitive touch interface, the new B6TS 'application ready' sensing chip offers features such as self-teaching, auto threshold and intelligent filtering to simplify system design and improve performance. The device compensates continuously for long term drift, and is tolerant of EMC interference.
In consumer electrical goods, the controls are normally designed to match the cosmetic appearance of the unit, and the B6TS offers customers a great deal of freedom to build their own circuits around the sensor chip using their own defined electrode configuration. Omron offers an evaluation kit called T-SIS (Touch sensor Smart Installation System) or "B6TWorkbench", which allows designers to experiment with user-definable settings to achieve the desired sensing performance.
The B6TS chip is suitable for use with almost all non-conducting materials such as plastic, rubber, glass, marble and wood, and it can also be used with indium tin oxide and other clear materials to create back light touch keys for graphics and special lighting effects.
