Touch screens enhance control panels, monitors and all-in-one PCs for commercial, industrial and military applications. They provide an integrated and programmable human-machine interface (HMI) for intuitive ease of use and eliminate the need for external input devices. Touch screens change the design paradigm. They enable the control panel to implemented as a standard commercial off the shelf (COTS) subsystem, a touch monitor or all-in-one PC, in a modular control system with reduced capital and operating costs. In most cases industrial control panels need to be durable and rugged; and they may need to work over an extended temperature range, in extreme environments, be glove operated, withstand heavy impacts and be capable of being washed down.
A D Metro supplies industrial touch screens that are durable and robust, can be integrated into enclosures for NEMA compliance and electromagnetic compatibility (EMC); with enhancement options to address the harshest environments. Standard resistive touch screen sensors provide a highly economic solution for moderate use applications and finger or glove operation. For heavier use, durability and embedded designs in environmental enclosures that will be exposed to water and chemicals, ULTRA resistive is the preferred choice. Alternatively, projective capacitive touch screens offer multi-touch capabilities for dry indoor environments, where smartphone style gesture operation is required.
