Resistive Touchscreen Solution

Proven Touch Technology for Applications Requiring Input Versatility and Environmental Durability

Resistive touchscreens are well suited for harsh environments where exposure to liquids, contaminants, or gloved operation is a factor. Our engineering teams design and manufacture each sensor to your exact substrate, stack-up, and performance requirements, including enhanced optics and multi-touch configurations.

Custom Resistive Touchscreens Built for Real‑World Performance

Custom resistive touchscreens are available in sizes ranging from 3.8 to 26 inches, designed for military, medical, aerospace, and industrial applications. Our resistive technology works with bare fingers, gloved hands, and any pointing device, making it well suited for harsh environments where input flexibility is a requirement.

4-Wire, 5-Wire, and 8-Wire Configurations

4-Wire The 4-wire configuration is well suited for compact and portable applications where low power draw is a priority. Our pressure-sensing 4-wire resistive touchscreens are sealable to prevent contamination from water, grease, dirt, dust, oil, and harsh chemicals, and are NEMA sealable. They work with bare or gloved fingers and any pointing device, making them a reliable choice for applications requiring input versatility in demanding environments.

5-Wire The 5-wire configuration is the most durable resistive touchscreen design and is widely used in industrial control and medical equipment applications. Voltage is applied to the four corners of the bottom glass layer while a single wire on the top sheet reads the point of contact, delivering consistent accuracy over time. Our 5-wire touchscreens are sealable to prevent contamination and support input from bare or gloved fingers and any pointing device.

8-Wire The 8-wire configuration operates on the same principle as 4-wire but adds four additional sensing points for improved accuracy and linearity in larger touchscreen sizes. Because of its input flexibility, low power draw, and accuracy, the 8-wire configuration is well suited for applications requiring precise input across a larger display area. Like our other resistive configurations, 8-wire touchscreens are sealable and NEMA compliant.

How Resistive Touchscreens Work

Resistive touchscreens consist of two conductive layers separated by small spacer dots. The bottom layer is a sheet of glass with a conductive coating on top. The top layer is a polyester sheet with a conductive coating on the bottom. The two conductive surfaces face each other and are held apart by the spacer dots until pressure is applied.

When a user presses the top sheet, the two conductive layers make contact and close the circuit. The controller reads the voltage at the point of contact and converts it to a touch coordinate.

The 5-wire design applies voltage to the four corners of the bottom glass layer. A single wire connected to the top sheet reads the point of contact. This approach delivers consistent accuracy and is the most widely used resistive configuration for industrial and medical applications.
