Photodiode SFH 2440 L saves on mounting height in the design of heart rate sensors. It can be flush-mounted on the printed circuit board (PCB), with longer leads ensuring secure mounting and reliable solder points. The component also features spectral sensitivity for measuring heart rate. SFH 2440 L is a large-area photodiode with the same…
Olson LED Ideal Light Source for Covert Surveillance
The infrared Oslon black SFH 4725S LED from Osram Opto Semiconductors has a wavelength of 940 nanometers, making it nearly invisible to the human eye, and its black package reflects virtually no ambient light. Together with its high optical output power of almost one watt, this infrared LED is the ideal light source for covert…
Pico Projectors Prefer LEDs
Traditional projection systems were meant to be used in classrooms, boardrooms, and other stationary locations. They typically were perched atop a desk or table and were used to project pictures, presentations, and other forms of information. They were often heavy and hard to move; they needed a specific type of surface to project off of;…
