About Bar Graph Arrays

Bar graph arrays are light emitting diodes (LEDs) that are used for solid state metering in applications such as audio monitoring, telecommunications, and instrumentation. These rugged board-mounted components are usually rectangular, X-Y stackable, and available in up to ten segments. Bar graph arrays with interlock mechanisms can be connected together in order to display long strings of information. Many devices feature easy-to-handle integrated circuit (IC) packages that are compatible with standard dual in-line package (DIP) sockets. Bar graph arrays that contain multi-color elements help eliminate many of the alignment, intensity, and color-matching problems associated with discrete light emitting diodes (LEDs). Consequently, they are often used in transportation, push button, and security applications that require easily recognizable segments, a wide viewing angle, and high on/off contrast.

Products & Services Related to Bar Graph Arrays

Annunciators

Annunciators and graphic display panels disclose the layout and annunciate the status and measurement parameters of industrial processes, security and fire alarms of buildings and manufacturing facilities, power distribution networks, and other operations.

Digital Bargraphs

Digital bargraphs measure process and electrical variables such as pressure, flow, temperature, speed, current, and voltage. There are two main types of products: light emitting diode (LED) and liquid crystal display (LCD).

Digital LED Displays

Digital LED displays are segmented or dot matrix displays allowing for numeric only and alphanumeric character representation.

Fire Alarm Control Panels

Fire alarm control panels (FACP) are systems which receive information from input devices (smoke detectors, heat detectors, etc.), process the information, and trigger an output device such as an audio or visual alarm.

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.

LED Message Displays

Message LED displays are typically commercial or industrial signs. They allow for larger characters and longer viewing distances than their smaller digital cousins.

LED Mounts and Lenses

LED mounts and lenses are used to mount LEDs and shape or transfer light output. Other components in this area include LED light pipes, headers, interconnects, and assemblies.

Light Emitting Diodes (LED)

Light-emitting diodes (LED) are PN junction devices that give off light radiation when biased in the forward direction. LEDs are used in a wide variety of indication applications.
