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.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
Two issues have been the bane of the plastics industry for as long as one can remember: The ban on plastic grocery bags and whether the use of bisphenol A (BPA) in plastics such as polycarbonate and PVC is harmful to humans.
