Directly inserted 3/5mm infrared transmitter/receiver 940nm transmitter/receiver LED pair tube F3/F5

Directly inserted 3/5mm infrared emitter tube

PRODUCT DESCRIPTION

Product model: 3MM/5MM infrared tube
Cap neck 3/5MM, wavelength 940, infrared receiver tube is black, so when it is powered, is not able to see the light, unlike LED, after power can emit light, can also see the light. The receiver is a kind of sensor, turn to receive infrared signal, therefore, only receive the infrared signal, the receiver tube can work. The shape of the infrared emitting tube is as transparent and colorless as the ordinary LED. Please do not use the LED lamp as the emitting tube to work, and only emit a little brightness of red light, which is infrared light (infrared signal). The wavelength of 940· the emitting tube belongs to the sensor class, and only the paired receiving tube can work effectively. A sense of this is the infrared tube!
