Relec has teamed up with RockTouch, a projective capacitive touch-panel (PCAP) manufacturer, to bring its products to the UK.

There are 12 sizes available, ranging from 7in up to 31.5in with all having a film-film-glass (F/F/G) structure with a choice of interfaces that include USB, RS232 or I²C. Some key features of Rocktouch PCAPs are:

A bespoke controller chip provides the best possible signal-to-noise Ratio at 32 V.  This greatly helps with EMC conformance and is suitable for applications such as automotive

Up to 10-point touch

Can be operated using gloves, even thick industrial gloves

Up to 10mm-thick cover glass

Industrial COF design for added protection from electrical noise and mechanical stress

Optional firmware features including: frequency hopping; water rejection and palm rejection

RockTouch has now also released its new X-H20 Line that will continue to operate perfectly with running water over the cover glass. This is available in all sizes.

Relec can either supply the touch panel as a component for customer integration, or with the help of Futurelabs (RockTouch’s parent company), it can provide the touch panel as part of an assembly to include the TFT panel. In addition, it can tailor the whole assembly to your application, and modify them to include various options, for example:

Improving the brightness

Optical Bonding for high brightness applications especially outdoor. This also offers substantial mechanical improvements and is ideal for rugged applications. It also resolves the problem of condensation forming between the display and touch panel

Applying various different surface treatments

Supplying with custom-tuned Interface Cards

Making the product more rugged

At Relec Electronics the philosophy is to help design engineers build better solutions.

We are proud to have one of the most comprehensive power supply ranges available, for both DC to DC and AC to DC applications. In addition, we offer a range of complementing products including EMC filters, switches and displays. Our aim is to build partnerships with customers and suppliers to both understand their requirements and to ensure a reliable supply of robust, yet technically advanced components that can be relied upon in the long term.

Power supplies, circuit protection and interface products form the backbone of our business. We work very hard to bring high-quality competitive products to the market, and our customers can be assured that any product we are promoting will not have reached them without full dialogue with the supplier together with a personal factory audit.

We believe the future is to offer our clients more choice thereby ‘adding value’ to their projects. This is achieved by offering custom products in all the lines we supply and by offering manufacturing services such as sub-assemblies and finished products. In our UK warehouse, we hold significant stocks of both standard and customer-specific parts and offer all the commercial services you would expect, including JIT, KANBAN, and specialist agreements tailored to suit individual customer needs.

Relec’s sales and technical support personnel, including our QA department, are all qualified engineers and are committed to ensuring that all aspects of our service meet and exceed today’s high expectations. We pride ourselves on providing extensive technical support for design engineers and full commercial support for our customers. By working with a limited number of manufacturers, who are leaders in their various technologies, Relec can provide the best solutions available.
