Choose either our conventional, standard resistive sensors or our patented ULTRA armored resistive sensors. ULTRA sensors are proven in the most physically demanding touch applications. An extensive range of 4-wire, 5-wire and 8-wire resistive sensors are available in either style.
A D Metro’s resistive touch products include a range of trusted and advanced controllers.
Our most popular 1-touch controller variant supports 4-wire or 5-wire resistive sensors and communicates through a standard USB interface. Other variants in this series attach to sensors using latching connectors specific to 4-wire, 5-wire or 8-wire sensors. There are further variants easily configurable to communicate either through USB or full voltage RS-232.
Our patented 2-touch resistive controller works with a range of unmodified 5-wire ULTRA or standard resistive controllers. Its unique 2-touch capability delivers pinch/zoom/rotate operations 5-wire resistive sensors through a standard multitouch USB interface.
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.
