Standard Resistive Sensors

5-Wire, 4-Wire & 8-Wire Resistive Touch Screen Sensors

Standard Resistive Sensors

A D Metro has been designing and manufacturing resistive touch sensors since 1995. This extensive experience has been incorporated into today’s designs, using advanced materials to produce the most reliable and cost effective resistive touch screen sensors available on the market.

A D Metro stands behind these high quality resistive touch sensors that target the most cost-sensitive applications.

Sensors include 5-Wire models that deliver reliability and longevity well beyond expectations. 5-Wire sensors are substantially less prone to the main mechanism of degradation of traditional resistive touch sensors – micro-cracking of the top layer of transparent conductive material (indium tin-oxide).

Compatible Controllers

Two-Touch functionality is available for our 1.85 mm and 2.85 mm ITO substrate glass, 5-wire ULTRA resistive sensors up to 21.3” in size with 0.1 mm ULTRA microglass, or up to 15.5” in size with 0.145 mm ULTRA microglass.

Please refer to our Resistive Sensor Catalog to identify these sensors.

How do resistive touch screen sensors work?

A resistive touch screen sensor is an analogue switch technology that is pressure activated. Two conductive coated layers (usually using Indium Tin Oxide [ITO]), facing each other, are separated by a layer of dielectric spacer dots. When pressure is applied to the top surface, the two layers come into contact and the controller locates the touch point. To determine the x and y coordinates, in 4- and 8-wire sensors a voltage gradient is applied to each layer in turn; and in 5-wire sensors the resistance is measured between the top layer and each of the four corners of the base layer.
