Additional Details:

The VLMT3100-GS08 IR emitting diode features a forward voltage of approximately 1.3 V to 1.6 V at a forward current of 100 mA. Its typical radiant intensity is around 40 mW/sr at 100 mA. The narrow viewing angle of ±10° allows for focused IR transmission, enabling longer range and better precision in applications like remote controls and light barriers. The package is a standard 5 mm through-hole type, facilitating easy integration into circuit boards. The spectral bandwidth is typically around 45 nm. The operating temperature range is usually between -40°C and +85°C.

In remote control applications, the VLMT3100-GS08 emits a modulated IR signal that is detected by the IR receiver in the controlled device. The narrow viewing angle helps to prevent interference from other IR sources and ensures reliable communication. In light barrier applications, the IR diode emits a beam of light that is detected by a phototransistor or photodiode. When an object interrupts the beam, the change in signal is detected, triggering an action. In proximity sensors, the IR diode emits a beam of light that is reflected back to a detector when an object is nearby. The amount of reflected light is proportional to the distance of the object.

The VLMT3100-GS08 is a lead (Pb)-free device and is compliant with RoHS regulations, ensuring its environmentally friendly design. It's suitable for a wide range of applications requiring reliable and efficient infrared emission.
