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.
Some of our culture's most enduring robots appeared in the 80s. The Aliens series produced another evil android, and we saw light robot fare in the form of Short Circuit. Two of the great robots of all time also showed up: The Terminator and RoboCop.
Optomec's third America Makes project for metal 3D printing teams the LENS process company with GE Aviation, Lockheed, and other big aerospace names to develop guidelines for repairing high-value flight-critical Air Force components.
This Gadget Freak review looks at a cooler that is essentially a party on wheels with a built-in blender, Bluetooth speaker, and USB charger. We also look at a sustainable, rotating wireless smartphone charger.
