Products/Services for Phototransistor Distributor

  • Phototransistors-Image
    Phototransistors - (89 companies)
    Phototransistors are solid-state light detectors with internal gain that are used to provide analog or digital signals. They detect visible, ultraviolet and near-infrared light from a variety of sources and are more sensitive than photodiodes...

  • Light Curtains-Image
    Light Curtains - (230 companies)
    Light curtains are photoelectric transmitters that project infrared beams to a receiver. They are used to guard openings and work spaces in or around machinery. When an opaque object interrupts the infrared beam, a stop signal is sent to the hazardous process to protect personnel or equipment.

  • Color Sensors-Image
    Color Sensors - (95 companies)
    Color sensors register items by contrast, true color, or translucent index. True color sensors are based on one of the color models, most commonly the RGB model (red, green, blue).

    Optical Design Services - (145 companies)
    Optical design services assist companies with the initial conception and design of optical, optomechanical, or optoelectronic devices or assemblies.
    Show More
    Photodiodes - (229 companies)
    Photodiodes are used for the detection of optical power (UV, Visible, and IR) and for the conversion of optical power to electrical power.

...accurately than old-style tachometer-generators. The simplest encoder is the incremental style. Typically, it uses a slotted wheel placed between an LED light source and a phototransistor. As the wheel rotates, it alternately passes then blocks light shining on the phototransistor. The phototransistor...
