RPM7138-H5R application field and working principle

Optical sensors are an essential tool of automated optical inspection allowing rapid detection of features, inspecting for quality assurance or to ensure the absence of flaws. These sensors can be easily equiped with lighting, in order to improve the contrast of the inspected scene.

Once the desired aspect of the inspected scene has been acquired, the optical sensor can then be used for the analysis of the data. The range of optical sensors is vast and the applications span across various industrial and medical fields.

Optical, or ‘photo’, detectors are a type of optical sensor. Generally, photo detectors are used to convert light into an electrical signal. This electrical signal can then be used to measure the intensity of the light source – reflected, emitted or absorbed. The resulting signal can have various applications, from measuring the presence of an object, to ensuring proper alignment of parts in an automated assembly process.

Among the various types of optical sensors, the remote receiver, or opto-receiver RPM7138H5R has a wide range of applications. The main usage of opto-receiver RPM7138-H5R is as a component of a remote sensing system. Such device is usually composed of the transmission module and the opto-receiver.

In the case of the RPM7138-H5R, the opto-receiver converts light into a DC voltage. The device is mostly used in remote control systems to detect the presence of any infrared radiation absorbed by its photodiode. Its wide operating range, from 500nm to 1000nm, makes it suitable for industrial, automotive, medical and consumer applications.

The construction of the RPM7138-H5R is mainly composed of two main elements – the photodiode and the amplifying transistor. The photodiode inside the device occupies most of its size and it is covered by a filter which allows radiation in the desired wavelength range to enter the device.

The outputs of the photodiode are connected to the transistor which amplifies the signal. The amplification is adjustable by a potentiometer which makes it possible to change the sensitivity of the device and optimize its performance.

The main advantages of the RPM7138-H5R are its wide operating range, its small size, and its adjustable sensitivity. It is compatible with many types of transceivers and can be easily incorporated in various applications.

In conclusion, the RPM7138-H5R is a type of opto-receiver suitable for a wide range of applications. The device is composed of a photodiode and an amplifying transistor which can be adjusted in order to optimize the performance of the device. It can be used to detect the presence of infrared radiation in a specific wavelength range and can be incorporated in an automated robotic system or any remote sensing application.
