Displays and control panels increasingly are comprised of modules that are combined to provide custom requirements. CRTs and flat-panel display technologies are assuming an ever-larger role in industrial equipment and consumer products. On operator panels where a few indicator lights might have sufficed years ago, there is more of an emphasis on providing a clear-cut and straightforward user interface. This trend has fostered a need for operator controls that are easy to understand. Displays play an important part in simplifying such controls. In more specialized instrumentation, indicator lights and alphanumeric readouts continue to play an important role. Liquid-crystal displays (LCDs) and electroluminescent displays are increasingly providing custom readouts in small, compact instrumentation. The simplest cathode-ray tube (CRT) displays are monochromatic units used to provide displays containing only alphanumeric characters, no graphics. Such CRTs come in typical sizes ranging from 4-in. diagonals on up to 19-in. diagonals and larger. The average price for such displays, when housed in ruggedized industrial enclosures, is generally a few hundred dollars or less. Typical applications include providing readouts of position on CNC or other industrial machinery. CRTs that provide more than just readouts of alphanumeric information increasingly are classified as being components of operator interface panels. In such applications, the CRT is frequently called upon to display icons and other graphic information that aids and abets the operator in interacting with the machine or system being controlled. The most common format for graphic video displays of this sort is the VGA standard that is widely used on personal computers. Graphic resolution is 640 X 480 pixels in standard mode displaying 256 colors. Higher resolutions are possible. One advantage of the VGA format for such applications is that, because it is used in high volumes, costs associated with both the CRT tube and the ancillary driving electronics
Products & Services
Flat Panel Displays
Flat panel displays (FPDs) are thin, flat, electronic devices used to display data. They are commonly used in notebook computers. Most styles include the housing and ports necessary to connect them to a computer.
Digital readouts are specialized displays for position and dimension readings from inspection gages and linear scales, or rotary encoders on machine tools.
Environmental Test Chambers and Rooms
Environmental test chambers and rooms are used to ensure the reliability of industrial products, especially electronic items, through prolonged exposure to one or more environmental parameters.
Touch Screen Displays
Touch screen displays are user-friendly input devices. The user touches the screen and the input is communicated directly to the computer.
Industrial Remote Controls
Industrial remote controls are wireless input devices that are used to control machines and equipment to which they are not directly linked. They use radio frequency (RF) signals, digital pulses, or infrared light to send signals from transmitters to receivers.
