Infrared Emitter

An Infrared emitter, or IR emitter, is a source of light energy in the infrared spectrum. This little part is a light emitting diode (LED) that is used in order to transmit infrared signals from a remote control. This simple device operates at 940nm and works well for generic IR systems. This emitter is driven up to 50mA with a current limiting resistor as with any LED device.

  • Continuous Forward Current: 50mA
  • Reverse Voltage: 5V
  • Operating Temperature: -25~+85°C
  • Wavelength: 940nm
  • Voltage - Forward (Vf) (Typ): 1.2V
  • Viewing Angle: 60°
  • Orientation: Side View

Infrared Emitter Product Help and Resources

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

    I tried it with a detector by connecting it the same way as the video in (infrared emitters and detectors) but it didn't work. The connection is an emitter in series with a 330ohm resistor. Any help please?
