App note from TT Electronics on reflective assemblies and the surfaces they need to effectively detect/sense. A reflective sensor provides a major mounting advantage to the designer because only one side of a sensing surface is required. However, there are a number of design variables that need to be considered to assure detection of the […]

App note: Photologic
Photologic components and applications from TT Electronics. Historically, optoelectronic components such as phototransistors have been analog output devices. The application engineer had to design with an output current from the phototransistor generated by a given input bias circuit. The advent of the integrated circuits and microprocessors has required the electronics world to turn digital. The […]
