B6TS-04LT-002 DEFAULT

Capacitive Touch Sensing ICs B6TS OMRON expands its switch product range by introducing the new touch sensor switch family B6TS which is based on a capacitive measurement principle: • B6TS-04LT – 4 channel sensor • B6TS-08NF – 8 channel sensor • B6TS-16NF – 16 channel sensor (Release 2007) Features • B6TS is ‘Application Ready’ The B6TS was developed to be highly tolerant of its working environment with adaptive features such as self teaching, auto threshold and intelligent filtering to meet the demands of most applications today. B6TS resists EMC and compensates continuously for long-term drift. • The customer has the ‘Freedom to Design’ With the exception of a few rules of thumb you are limited only by your imagination. Panel designers are free to decide electrode size, shape, spacing etc. The design is quick and easy – simulation, pcb design, cover material design, assembly – Finished Panel Solution! • ‘Freedom in Material’ You can make touch keys through any nonconducting panel material including plastic, rubber, glass, marble and wood. You can use low cost commercial PCB materials to create your designs. Most designs can be done on low cost single sided PCB like FR-2 or CEM-1. • ‘Standard or custom’ B6TS is µController based, so we can provide off the shelf solutions as well as “quick to market” customized types. Additional features may be possible at very low development cost. Tools • Excellent Tool support enables the customer to have an easy entry in the capacitive sensing technology and customized panel solutions. ■ Evaluation kit ‘B6T Workbench’ which includes • A PC tool to program custom parameters of the B6TS like: (Sensitivity adjustment, hysteresis, timing to judge a touch event, driftcompensation, output mode selectable -> a) momentary switching b) latching switching c) serial data via SPI interface) • RS232 to SPI interface board • Demo panel for either (4, 8 or 12 channels) to have an application ready evaluation platform available. The demo panel can be used to immediately carry out investigations with different cover materials and geometries. ■ Simulation Software To evaluate the behavior of the custom panel design before making a PCB. ■ Application Note Touch panel reference design.
