Bar graph arrays are light emitting diodes (LEDs) that are used for solid state metering in applications such as audio monitoring, telecommunications, and instrumentation.
|
|
Darlington transistors (Darlington pairs) are semiconductor devices that combine two bipolar transistors in a single device. They provide high current gain (commonly written ß) and require less space than configurations that use two discrete transistors.
|
|
Illuminators are used to provide adequate contrast for imaging. Illuminators include backlights, LED illuminators, and fiber optic illuminators.
|
|
Digital LED displays are segmented or dot matrix displays allowing for numeric only and alphanumeric character representation.
|
|
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.

Light guides conduct the flow of light from a light source to a point of use in areas that are too small or too hazardous to permit the installation of a light bulb. There are two basic types of light guides: liquid and fiber optic.

|
Liquid crystal display (LCD) modules are used at the component level in place of less efficient displays such as cathode ray tubes (CRTs). These modules do not include a housing and must be incorporated into a larger instrument or system.
|
|
Optocouplers are capable of transferring an electrical signal between two circuits while isolating the circuits from each other.
|
|
Photoconductive cells are light-sensitive resistors, in which resistance decreases with an increase in light intensity when illuminated.
|
|
Photodiodes are used for the detection of optical power (UV, Visible, and IR) and for the conversion of optical power to electrical power.
|
|
Phototransistors are solid-state light detectors with internal gain that are used to provide analog or digital signals. They detect visible, ultraviolet and near-infrared light from a variety of sources and are more sensitive than photodiodes. This category includes photodarlingtons.
|
|
Pilot lights and indicator lights are incandescent or LED indicating lights for machines or instruments.
|
|
Pushbutton switches are mechanical switches defined by the method used to activate the switch. The activation method is typically in the form of a plunger that is pushed down to open or close the switch.
|
|
Rocker switches are actuated by a standard or dual rocker or paddle.
|
|
Switches are devices that allow electric current to flow when closed and prevent current flow when opened. Switches, All Types are a high level search form that includes options for all switch types. Search forms for specific switch actuator types are also available.
|
|
Toggle switches are actuated by moving a lever back and forth to open or close an electrical circuit.
|
|
Transistors are electronic devices made of semiconductor material that amplify a signal or open or close a circuit.
