# Optical Sensors - Photo Detectors - Remote ReceiverOptical sensors consist of components that detect changes in the optical field, which can be a combination of visible and infrared light. One of the most common optical sensors is the Photo Detector. The Photo Detector detects changes in the light intensity, typically from visible or infrared light sources, and is an important tool for remote sensing applications. One such remote receiver is the PNA4612M.The PNA4612M is a photo detector module that is optimized for infrared transmission. It consists of a strong 8.7mm ceramic package with an integrated acoustic wave guide, an infrared lens and a pre-amplifier. The module has a wide turn-on wavelength of 870nm, a high sensitivity of 1A/W and a low noise level of 1nV/sqrtHz. This allows it to detect weak light sources at a distance of up to several meters, making it an ideal solution for remote sensing applications such as barcode readers, presence detection, and temperature measurement in various industrial and automotive environments. The working principle of the PNA4612M remote receiver is based on piezoelectric transduction. This process occurs when a piezoelectric material, such as quartz, is exposed to an external force. Piezoelectric transduction produces a voltage in response to a mechanical stimulus, which in this case is infrared light. When an infrared signal is incident on the ceramic package, the sensor will generate an electrical signal that is proportional to the intensity of the incident light. The PNA4612M is typically connected to an amplifier and a signal processor, which convert the electrical signal into an output signal that can be used to activate other devices or systems. For example, this signal could be used to trigger a warning system in an industrial facility, or it could be used to activate a vehicle’s headlights in response to low light levels.The PNA4612M is a highly sensitive photo detector and is well-suited to applications that require the detection of weak light sources. It offers a wide turn-on wavelength, excellent signal to noise ratio, and low power consumption. This makes it an ideal choice for a wide range of applications, including remote sensing, barcode readers, presence detection, temperature measurement, and a variety of other industrial and automotive applications.
