TSAL620 Super-bright 5mm IR LED 940nm High Power Infrared Emitting Diode

1 review

Infrared LEDs are used for remote controls (they're the little LED in the part you point at your TV) and 'night-vision' cameras, and these little blue guys are high powered ones! They are 940nm wavelength, which is what nearly all devices listen to. They're 20 degree beamwidth, and work great for any kind of remote control application.

IR Beam Interruption Sensor - LED 3mm - 0-50 cm

1 review

The sensor reacts to an interruption in the beam of infrared light that is transmitted between the transmitter and receiver. When the beam is interrupted by another object, the receiver signals this event by lighting up. The module is equipped with a 3 mm IR LED with an illumination angle of 10°. Beam interruption systems are used e.g. in measuring gates.
