FR4 IR Infrared Transmitter Module - Red + Transparet (3.5~5V)
Infrared transmitter tube is also called infrared emitting diode£¬ which is the diode type. It can converts the electricity into near infrared light (non-visible light). - Mainly used in all kinds of photoelectric switches and remote control transmitter circuit. - Physical parameter: transmitting distance£¬ emission angle(15'£¬ 30'£¬ 45'£¬ 60'£¬ 90'£¬ 120'£¬ 180')£¬ luminous intensity£¬ wavelength. - Usually small power infrared transmitting tube£¬ diameter: 3mm£¬ 5mm£¬ forward voltage: 1.1~1.5V£¬ current: 20mA; Medium-power and high power infrared transmitting tube diameter: 8mm£¬ 10mm£¬ medium-power transmitting tube forward voltage: 1.1~1.5V£¬ current: 20mA; High power transmitting tube forward voltage: 1.5~1.9V£¬ current: 350mA.
