This Product Selection Guide contains information to help select products in the Photo Detectors - Logic Output category on DigiKey.com
Products in the Photo Detectors - Logic Output family contain a light sensitive element such as a photodiode or phototransistor, and produce a binary (two-state) output indicating whether the amount of incident light exceeds a predefined threshold. They find use in the construction of photointerrupter devices, encoders, and similar devices where a basic light detection function is sufficient.
SelectionCharacteristics
Specifications to determine which logic output photo detector is right for your application.
Wavelength: The peak wavelength of the wavelength spectrum that will produce a valid output.
Type: The type of technology used in the photo detector.
Output Type: Indicates the type of electrical signal the device provides, such as
logic, active low, NPN, etc.
Package/Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the suppliers device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
