Resistive Touchscreens were the real breakthrough in common use touchscreen technology. With resistive touchscreens also came flexible, cost effective touchscreen technology which is available for industrial and medical use. Nowadays resistive technology is a mature well known technology. Resistive technology has been available within the SCHURTER group for nearly 20 years. SCHURTER has built upon extensive knowledge of resistive technology, the manufacturing of the products and the materials used. SCHURTER can help you to fulfil your needs with a wide range of standard 4-wire, 5-wire and 8-wire sensors. If in the unlikely case a standard sensor will not fit your display, SCHURTER can assist you with the design of a custom made resistive touchscreen.
A wide range of standard sensors in 4-, 5- and 8-wire technology as well as customer-specific sensors which fullfill application-specific requirements are available.
For special applications and extended specifications, SCHURTER offers you special types of resistive touchscreen technology in various designs.
Based on our knowledge and experience with this resistive touchscreen technology, we can assist you with the design of your individual resistive touchpanel specifically to suit your application.
The general specifications of our industrial resistive touchscreens are:

- Construction: film-on-glass (FG), film-film-glass (FFG) or PC or others
- ITO glass thickness: 0.7 mm, 1.1 mm, 1.8 mm, 2.8 mm
- Contact: ZIF, Berg, AMP, AMP compatible or others
- Input method: finger, gloved finger, stylus
- Activation force: 0.1 N to 1.0 N depending on design
- Surface hardness: 3H or higher
- Operating temperature: -20 ℃ to 70 ℃
- Storage temperature: -40 ℃ to 80 ℃
- Linearity: < 1.5% (4-, 8-wire technology) / < 1.0 - 1.5% (5-wire technology)
SCHURTER provides various standard controllers for USB and serial interfaces for contacting all resistive touch screen technologies.
To increase the mechanical stability and the realization of dirt-free touch panels, resistive touch screens are laminated over the entire surface with a customer-specific overlay film.
Resistive touch screens are available in different designs:
1) 4-wire technology are most commonly used technology
There are 2 electrodes for the X direction on the top circuit and 2 electrodes for the Y direction on the bottom circuit. This is the most flexible and cost effective technology.
2) 5-wire technology
This technology is suitable in harsh environments with a high volume of operations required. The 4 electrodes are specially designed on the bottom circuit and sensed by the top film. As the electrodes are burned into the glass, a highly durable system is created.
3) 8-wire technology
This technology is like the 4-wire resistive but has extra sense lines for each electrode. This extra sense line is used to compensate resistance changes due to rapid changes in temperature. This will provide a stable system, suitable for environments subject to constantly changing conditions.
4) Matrix/digital technology
In this technology the contact fields are defined within the conductive layers of the touchscreens. This will provide a very robust and reliable system but is not as flexible in the software design as the above mentioned technologies.
Please discuss with your representative the best/most suitable resistive touch technology for your application.
Advanced resistive touchscreen technology
SCHURTER offers you special forms of resistive touch screen technologies which are optimized for your specific application requirements.
Glass-Film-Glass (GFG) touchscreens
GFG touchscreens offer high resistance to scratches, abrasion and chemicals due to an additional laminated glass layer on the surface and they can also be operated with gloves.
For outdoor applications we offer the GFG LR technology (low reflective) with integrated Polarizer filter and Lambda quarter film.
Various shielding materials are available for integration into the GFG touch screen to prevent EMC interferences.
Our resistive touchscreens are implemented in many different applications and highly demanding markets.
From the Medical market to the Automation market, you can find SCHURTER’s customer-specific touchscreens everywhere.
