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 ’ Y ou can make touch keys through any non- conducting panel material including plastic, rubber, glass, marble and wood. Y ou 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. Target Applications  Dish washer  Washing machine  Oven  Fitness equipment  Te lev i si on  Medical equipment  HVAC controls  Lighting controls  Elevator  Automatic door  Vending machine  Alarm clock  In general Man Machine Interfaces (MMI)  3 Dimensional switch solutions

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 A DDRESS THE RISKS, AND THAT THE OMRON PRODUCT IS PROPERL Y 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.
