Made for assembly line, machine automation, and other applications, this RoHS-compliant wide gap optical sensor includes an emitter-sensor pair. Its LED and phototransistor are made to work over up to 12 inches in industrial environments. The sensor components are mounted in threaded color-coded housings. The emitter-sensor pair uses an LED with a 935 mm peak wavelength and a silicon phototransistor. The pair will mate with a Molex 03-06-2023 connector with either male (for the LED) or female (for the sensor) pins. The output phototransistor performs at collector-emitter voltages of 30V, emitter-collector voltage of 5V, and power dissipation of 100 mW. The LED has a maximum continuous forward dc current of 40 mA, a reverse voltage of 2V, and power dissipation of 100 mW.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
