Optical Sensors often used in multiple industries due to their advantage of fast response, wide working range, long life service, and easy installation. One example of optical sensor is RPMS2381-H19E4A which is a remote receiver.

Application Field and Working Principle of RPMS2381-H19E4A

The RPMS2381-H19E4A is particularly suited for applications of industrial automation, home and medical appliances, security systems, and surveillance. This receiver is a member of Universal Asynchronous Receiver/Transmitter (UART) module, with power supply: operating current: 2.4 mA to 3.6 mA, and standby current: 0.6 μA.

The RPMS2381-H19E4A is utilized with a transmitter to communicate with the terminal. It uses infrared (IR) technology to receive signals. Among IR technologies, the module utilizes the most advanced one – the Code Exchange Technology (CDT). This technology evaluates specific codes which get exchanged between the receiver and transmiter.

When the signal of the transmitter is sensed by the receiver circuit of the RPMS2381-H19E4A, a corresponding signal is given to the terminal. It then establishes a connection with the UART interface of the terminal. Basically, the UART circuitry initializes communication by generating a corresponding signal to that of the transmitter, and vice versa. Once communication is established, the data is transferred and the connection is disconnected.

This receiver module is easy to use. The device is connected to the terminal directly via terminal headers. It has a multipurpose controller, the TA7807, a 2-pin connectors for connecting with the antenna, and two high-speed optocouplers for controlling the power supply and standby modes.

In summary, the RPMS2381-H19E4A is an advanced optical sensor, and a member of the Universal Asynchronous Receiver/Transmitter module, suitable for industrial automation, security systems, home and medical appliances, and surveillance. It utilizes infrared technology with continuous data exchange to create a secure connection between the receiver and the transmitter. The relay switched power supply and stand-by modes are managed by high-speed optocouplers. The device is easy to install, long lasting and supports a wide range of applications.
