3mm IR Transmitter & Receiver

3mm IR Transmitter and Receiver pair to build object sensors, color sensors, line sensors, distance sensors, etc. Both the transmitter and emitter are built to work on the the 940 nm wavelength. Use these 3 mm IR Transmitter and Receiver in places where a 5 mm IR Transmitter and Receiver cannot is too big to fit in. These sensors are perfect for making custom wheel encoders.

Features:

• Infrared Transmitter/Emitter
• 3mm in diameter
• Wavelength: 940nm
• Anode: Long pin (small flag)
• Cathode: Short pin (big flag)
