RPM882-H12E4

The RPM882-H12E4 is an infrared(IR) transceiver module developed by Rayplus Microwave,a leading manufacturer of telecom components. It uses the IrDA physical layer 1.4 standard protocol and works in the 850nm wavelength optical range. The transmit and receive distances are typically 1m or less. It consists of an integrated transmitter and receiver. The RPM882-H12E4 is suitable for a wide range of applications in industrial, medical, security and consumer electronics, such as data transmission, remote control, and voice recognition.

The working principle of the RPM882-H12E4 is based on the IrDA physical layer protocol, which is divided into four layers. The first layer is the laser diode, which converts electrical signals into pulses of infrared light. The second layer is the optical filter, which filters out unwanted light frequencies. The third layer is the photodiode, which converts the received infrared light into electrical signals. The fourth layer is the signal processor, which decodes the electrical signals into data.

The RPM882-H12E4 is a robust, reliable module suitable for a variety of applications. It is energy efficient, has low power consumption and is able to operate at a wide range of temperatures between -40°C and +85°C. It measures 20 cm X 27 mm and weighs approximately 10g. It also has an optimal range of up to 20m in open space and is EMI and EMS compliant.

In conclusion, the RPM882-H12E4 is a reliable and efficient Infrared transceiver module suitable for a wide range of applications. It uses the IrDA physical layer protocol for encoding and decoding data and works in the 850nm wavelength range. It is robust and energy efficient, with low power consumption and a wide range of operational temperatures. It is EMI and EMS compliant and has an optimal range of up to 20m in open space.
