Capacitive Touch Sensing - Film

KEE Group's Capacitive Touch Sensing Film Solutions offer a low cost, low power interface with greater design flexibility, including scroll wheels and slider switches as well as standard buttons. Thin and flexible, it can be applied to a curved surface. From touch sensing that uses your body's capacitance to detect and activate, to metallized capacitive touch switches that utilize a flexible metallic surface above the sensor, KEE Group has the capacitive film solution for your application.

Advantages

• It is flexible allowing it to conform to curved surfaces
• It can be adhered directly to the rear of the touch surface
• Backlighting and indicator lighting options available
• Totally sealed and washable
• Surface contaminants and moisture have no effect
• Can be used with gloves
• Suitable for Braille applications
• ROHS compliant
• The FPC tail is integrated with the circuit so there is no need for a separate interconnect
• KEE Touch can be incorporated on to IMD/IML designs
• Replace expensive and heavy glass with plastics of varying thickness
• Stainless steel or Aluminum overlays with capacitive touch now possible
• Easy conversion of existing product

Capacitive Touch Sensing - on Metal

 The graphic layer on the Metallized Capacitive Switches can be metal or plastic and must be deflected 20 to 50 microns to detect touch.  This is especially useful in situations where a light actuation is desired for activation of switch. No more false activation!
