OPB390N11 is a slot type photointerrupter which includes a light emitting diode (LED) and a phototransistor. This device is intended for use in applications such as switch, presence sensing, motion and speed detection, rate counting, and robotic control. The most common application is in high-end gaming consoles, where optical sensors are used to detect the movement of the controller.

The OPB390N11 is designed to provide a transistor output signal in response to a single light beam. It has a slot type housing which provides a large interception area for the infrared light beam. Inside the device, two chips shaped in a rectangular shape are mounted on a PCB. The LED is mounted on one side of the chip and the phototransistor is mounted on the other side.

The working principle of the OPB390N11 is pretty simple. When an infrared light beam passes through the slot, the phototransistor is triggered and a transistor output signal is generated. The signal can then be read by a host controller and the motion is detected. The response time of the device is very fast and it can detect movements up to 18kHz.

The OPB390N11 is a very reliable device and it can operate in temperatures ranging from -40 to +85℃. It has a very low power consumption and can operate at a supply voltage of 5V. It is also very robust and it can withstand shocks and vibrations up to 60G.

The OPB390N11 is one of the most widely used optical sensors for gaming, robotics, and automated manufacturing applications. It is an effective device for detecting fast moving objects in a short range. It is a cost effective solution and offers high reliability and long term performance.
