Capacitive Touch Sensing ICs B6TS 1
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.

Certain Precautions on Specifications and Use
1. Suitability for Use. Seller shall not be responsible for conformity with any stan-
dards, codes or regulations which apply to the combination of the Product in
Buyer's application or use of the Product. At Buyer's request, Seller will pro-
vide applicable third party certification documents identifying ratings and limi-
tations of use which apply to the Product. This information by itself is not
sufficient for a complete determination of the suitability of the Product in com-
bination with the end product, machine, system, or other application or use.
Buyer shall be solely responsible for determining appropriateness of the par-
ticular Product with respect to Buyer's application, product or system. Buyer
shall take application responsibility in all cases but the following is a non-
exhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical
interference, or conditions or uses not described in this document.
(ii) Energy control systems, combustion systems, railroad systems, aviation
systems, medical equipment, amusement machines, vehicles, safety
equipment, and installations subject to separate industry or government
regulations.
(iii) Use in consumer products or any use in significant quantities.
(iv) Systems, machines and equipment that could present a risk to life or
property. Please know and observe all prohibitions of use applicable to this
product.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY WITHOUT ENSURING THAT THE SYSTEM
AS A WHOLE HAS BEEN DESIGNED TO ADDRESS THE RISKS, AND THAT
THE OMRON PRODUCT IS PROPERLY RATED AND INSTALLED FOR THE
INTENDED USE WITHIN THE OVERALL EQUIPMENT OR SYSTEM.
2. Programmable Products. Seller shall not be responsible for the user's
programming of a programmable product, or any consequence thereof.
3. Performance Data. Performance data given in this publication is provided as
a guide for the user in determining suitability and does not constitute a war-
ranty. It may represent the result of Seller's test conditions, and the users must
correlate it to actual application requirements. Actual performance is subject to
Seller's Warranty and Limitations of Liability.
4. Change in Specifications. Product specifications and accessories may be
changed at any time based on improvements and other reasons. It is our prac-
tice to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifica-
tions of the Product may be changed without any notice. When in doubt, spe-
cial part numbers may be assigned to fix or establish key specifications for
your application. Please consult with your Seller representative at any time to
confirm actual specifications of purchased Product.
5. Errors and Omissions. The information in this publication has been carefully
checked and is believed to be accurate; however, no responsibility is assumed
for clerical, typographical or proofreading errors, or omissions.
6. RoHS Compliance. Where indicated, our products currently comply, to the
best of our knowledge as of the date of this publication, with the requirements
of the European Union's Directive on the Restriction of certain Hazardous
Substances ("RoHS"), although the requirements of RoHS do not take effect
until July 2006. These requirements may be subject to change. Please consult
our website for current information.
