Projected Capacitive Multi Touch (PCT 40 Points)

The Multi Touch sensors are based on proven Projected Capacitive Technology (PCT), using the
latest mutual capacitive sensing developments.

The unique sensing characteristics of PCT™ sensing eliminates the need for an operating force, providing users with the same levels of touch sensitivity experiences with the latest smartphones and tablet PC’s but on a much larger scale, and in any environment or location.

ADVANTAGES

• Highly durable, vandal and scratch resistant
• Fast and accurate response times
• Increased reliability and life expectancy
• Works with gloved and ungloved finger
• Performance unaffected by moisture and surface contaminates
• Drift-free operation, one time calibration required
• Operation with gloved and un-gloved finger
• 10 independent touch points
• Advanced “palm rejection” function eliminates false touches in angled/ table-top applications
• ARM 32-bit Cortex microprocessor enables rapid touch detection (~1ms output)
• Firmware can be updated easily and remotely
• Detachable and completely independent of touch sensors, helps servicing
• Output protocol available upon request
• Native driver support for Windows 7, 8 and Linux 3.5.1+ kernels

FEATURES

• Chemically, physically and mechanically inert glass touch surface
• Ability to create a fully sealed design that complies with NEMA 4, 12 and IP 65 standards
• Size range from 15”- 82”
• Excellent light transmission with optional optical coating enhancements
• Compatible with a variety of operating systems including Linux
• Customisable options include: glass thickness and surface treatment, printed borders and logos

OPERATION

The touchscreen is divided into an X-Y matrix of sensing cells, using an array of embedded 10μm copper electrodes, which are near invisible to the human eye on the powered display. These electrodes are connected to an controller board, and a charge is applied to the array.

When a finger or conductive stylus approaches the surface of the sensor, a change in the charge is detected in the nodes immediately beneath adjacent cells; the position is then determined by the controller and firmware combination. Unlike conventional capacitive systems the active component of PCT™ is embedded behind the front substrate, ensuring protection, long life,
and stability.

The unique sensing characteristics of PCT™ sensing eliminates the need for an operating force, providing users with the same levels of touch sensitivity as experienced with the latest smartphones and tablet PC’s but on a much larger scale, and in any environment or location.

APPLICATIONS

The PCT Touch sensors are a durable and cost effffective method to meet the latest requirements for multi-touch and multi user interactivity, while still maintaining the ultra high levels of durability PCT touch is known for.

The construction is resistant to damage caused by moisture, heat and surface contaminates making the Multi Touch PCT the perfect choice for digital signage, gaming and entertainment, touch tables and outdoor Kiosks.

As with conventional PCT, the sensor also works "through glass" by adding a substrate or toughened cover glass for added protection. The cover glass may have black printed borders to give a one plane tablet look.
