Building Blocks of an Intelligent Network with Photodiode Sensors

On the Path to Industry 4.0

LASER COMPONENTS revamped InGaAs and extended InGaAs photodiode technolgy, which has led to the development of not only the components themselves but to groundbreaking industrial "Plug&Play" sensors as well - the MAJOR series.

The photodiode sensors have a panchromatic detector with a sensitivity range of 450 nm to 2000 nm and a reduced temperature dependence.

They work reliably in (core) systems and are able to read out evidential data - e.g. data can be tagged with a time stamp. Furthermore they have a calibration option, a digital and analog output, an internal storage capacity, and are integrated in a housing with an external M12 thread. Powerful electronics have been embedded into the MAJOR-A. It offers an arithmetical averaging between measurement values, an offset correction, and the option "measure on demand". Additional features are the automatic amplification adjustment and the programmable amplification.

The built-in photodiode is also made by LASER COMPONENTS. At wavelengths below 2100 nm, the temperature coefficient of the IG22X1000S4i is less than 0.01%/K (see figure). Thus, a temperature change of 50 K results in a deviation of only 0.5%. Inside the MAJOR it is possible to improve this value again via software.
