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 mate-

rial design, assembly – Finished Panel Solution!

• ‘Freedom in Material’ You can make touch keys through any non-

conducting panel material including plastic, rubber, glass, marble

and wood. You can use low cost commercial PCB materials to cre-

ate 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 pro-

vide 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 solu-

tions.

■ Evaluation kit ‘B6T Workbench’

which includes

• A PC tool to program custom parameters of the B6TS like: (Sensi-

tivity adjustment, hysteresis, timing to judge a touch event, drift-

compensation, 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 materi-

als and geometries.

■ Simulation Software

To evaluate the behavior of the custom panel design before making a

PCB.

■ Application Note

Touch panel reference design.
