One-Touch Resistive Controllers

A D Metro’s resistive touch controllers can interface over USB or full voltage RS-232. They support 4-wire, 5-wire or (optionally) 8-wire resistive touch sensors up to 24 inches in size. The touch controller boards are easy to integrate into the wide variety of touch sensing applications that use USB HID-mouse and HID-digitizer device types. Most operating systems have full built-in USB HID compatibility.

A D Metro resistive touch controllers dynamically adapt to touch screen electrical characteristics such as sensitivity, contact resistance, and capacitance. The controllers deliver advanced touch response, accuracy and performance with up to 150 touch point reports per second of filtered coordinates, accurately tracking motion for applications such as signature capture.

A D Metro resistive touch screen controllers support displays for industrial control, self-service kiosks and POS terminals, as well as smaller, mobile, handheld computer and medical devices. Resistive touch provides the advantages of easy integration, low total system cost, the acceptance of single finger, thick glove or stylus input, full EMC immunity, and the ability to work when dirty, wet or even when immersed in salt water.
