ZYPOS touch sensors - Zytronic - #1

ZYPOS®

A cost effective solution for demanding touch applications.

ZYPOS touch sensors are manufactured using the latest cold lamination process, and are based on Zytronic's award-winning embedded Projected Capacitive Technology (PCT™) that offers:

• Increased reliability and life expectancy

• Performance unaffected by moisture and surface contaminants

• Operation with gloved and ungloved finger

• Drift-free operation - no recalibration reguired

• A fully laminated, embedded sensing construction that is highly durable, vandal and scratch resistant

• Fast and accurate response time

• The ideal solution for today's demanding environments

ZYPOS provides the designer of touch displays with unique competitive advantages including:

• A standardized range of sizes from 7" to 20.1" that provide the most cost effective PCT sensors available

• A chemical, physical and mechanically inert 3mm thick glass touch surface

• A touch sensor that can operate through a covering medium

• Greater user durability

• The ability for the integrator to design sealed surfaces that comply with NEMA 4,12 and IP 65 standards or higher

• Excellent light transmission

• Output protocol compatibility for a variety of operating systems

Applications

Zytronic's ZYPOS sensors are proven to meet today's demanding touch reguirements. The ZYPOS touch sensor is extremely durable and dependable, and its construction protects against damage caused by moisture, heat and surface contaminants without any compromise on the brightness or optical clarity of the display.

The sensors can be used in a variety of applications including, medical displays, kiosks, industrial human machine interfaces (HMI) and video juke boxes.

Operation

The electronic controls effectively divide the screen into pixel-sized sensing cells, using an array of embedded microfine single track electrodes which are not ITO based, and are near invisible to the human eye on the powered display. These tracks are connected to an electronic controller board, and an oscillation freguency is established for each track. Touching the glass causes a change in the oscillating freguency of the tracks around that particular point; the position is then determined by the controller and firmware combination. Unlike conventional capacitive systems the active component of PCT sensors is embedded ensuring protection, long life, and stability.

The unigue PCT sensing characteristics of ZYPOS sensors eliminate the need for an operating force. Users are therefore not reguired to use credit cards, pens and other potentially damaging implements to activate the sensor.
