System Components

Photodiode amplifiers (also called transimpendence amplifiers) are highly sensitive, monolithic amplifiers for optical pulse detection and amplification. They are used for light barriers, light curtains and sensors. They are fully integrated photodiode amplifiers with constant light suppression. Here, too, the particularly small footprint is ideally suited for miniaturization. They reduce the components enormously and simplify every design.

The output drivers from Espros are used for digital data communication in modern automation environments with long distances of up to one kilometre. Signal attenuation over the cable length and large capacitive loads have a large influence on the transmission. The output drivers from Espros provide universal low or high power output drivers for 24 volt interfaces. The devices can drive loads with 50mA at 30 Volt. At higher currents or higher voltages, the output drivers can drive external power transistors. The transistor is protected against overcurrent by the epc output driver.

Optical filters from Espros are used to block special wavelengths, to make the optical sensor sensitive to certain wavelength ranges or in a narrow band. Espros offers the optical, universal IR (infrared) bandpass filter with center wavelength of 860nm. The filter is positioned on a glass carrier and is suitable for applications with High Power LED with 850nm.
