Optical Sensors, and in particular Photo Detectors and Remote Receivers, play a key role in a wide range of applications. One such device is the RPM7137-H9R, a remote receiver module designed and manufactured by Panasonic Corporation. In this article, we will look at the application fields and working principle of the RPM7137-H9R.

The RPM7137-H9R is an optoelectronic module designed for use in a variety of transmission systems, specifically those that utilize infrared light as the medium of communication. As such, the RPM7137-H9R is used in a number of applications, including remote control of devices, home automation, and the programming of audiovisual equipment. In addition to these applications, the module can also be used in medical, security, and industrial automation applications.

The module itself consists of a high efficiency infrared emitting diode and a phototransistor which detect the presence of an infrared light source and modulate the detected signal. This modulation allows the device to be used for digital data communication purposes, such as remote control or home automation. The module is highly sensitive to the presence of an infrared light source, enabling reliable and secure transmission over short distances.

The working principle of the RPM7137-H9R is fairly simple. The emitting diode emits infrared light, which is then detected by the phototransistor. The phototransistor then converts the infrared light into an electrical signal, which is modulated by the onboard circuitry and sent back to the transmitting device. This modulation is used to detect the presence of an IR light source and to send data back to the transmitting device.

In summary, the RPM7137-H9R is a remote receiver module designed for use in transmission systems that utilize infrared light as the medium of communication. The device is highly sensitive to the presence of an infrared light source, allowing reliable and secure transmission over short distances. The module consists of an infrared emitting diode and a phototransistor, which detect the presence of an infrared light source and modulate the detected signal for digital transmission.
