What is an Infrared Emitter?

An infrared emitter, or IR emitter, is a source of light energy in the infrared spectrum. It is a light emitting diode (LED) that is used in order to transmit infrared signals from a remote control. In general, the more they are in quantity and the better the emitters are, the stronger and wider the resulting signal is. A remote with strong emitters can often be used without directly pointing at the desired device. Infrared emitters are also partly responsible for limits on the range of frequencies that can be controlled. An IR emitter generates infrared light that transmits information and commands from one device to another. Typically one device receives the signal then passes the infrared (IR) signal through the emitter to another device.

Types of Infrared Emitters

There are several different kinds of infrared emitters. At Future Electronics we stock many of the most common types categorized by wavelength, angle of half intensity, intensity, forward voltage, packaging type and forward (drive) current. The parametric filters on our website can help refine your search results depending on the required specifications.

The most common sizes for wavelength are 875 nm, 880 nm, 890 nm, 940 nm and 950 nm. We also carry infrared emitters with wavelength up to 940 m. Forward voltage can range from 800 mV to 5 kV, with the most common sizes being 1.2 V, 1.5 V and 1.7 V.

If you have a preferred brand, we deal with several manufacturers such as Everlight, Fairchild, Lite-On, Optek or Vishay, among other manufacturers. You can easily refine your infrared emitter product search results by clicking your preferred infrared emitter brand below from our list of manufacturers.

Applications for Infrared Emitters:

Infrared emitters can be found in several industries. Many coating processes require heat, and infrared heat can be adjusted to the kind of coating. Infrared heat is used in hundreds of processes in the automotive industry. For example, infrared heat makes sure decorative carpeting fits precisely. Also, many glass processing activities require heat and an infrared emitter can be adjusted to the specific process. In the printing process, drying of printing ink is much more efficient if an IR emitter is adjusted to the ink. Another application for IR emitters is when they are used with quartz reflectors to make solar cells. Besides all of these applications, IR emitters can be found in the plastics, food, wood and textile industries, among others.

Choosing the Right Infrared Emitter:

When you are looking for the right infrared emitters, you can filter the results by various attributes with the FutureElectronics.com parametric search: by Wavelength (830 nm, 890 nm, 940 nm, …), Forward Voltage (800 mV to 5 kV) and Drive Current (from 50 uA to 1A) to name a few. You will be able to find the right infrared emitters for infrared emitting diodes, an infrared emitter circuit, ceramic infrared emitter, infrared light emitting diode (led) emitter or infrared emitter and detector.

Infrared Emitters in Production Ready Packaging or R&D Quantities

If the quantity of infrared emitters required is less than a full reel, we offer to customers many of our programmable infrared emitter products in tube, tray or individual quantities that will help you avoid unneeded surplus.

In addition, Future Electronics offers clients a unique bonded inventory program that is designed to eliminate potential problems that could arise from an unpredictable supply of products containing raw metals and products with long or erratic lead times. Talk with your nearest Future Electronics branch and find out more on how you and your company can avoid possible shortages.
