The EE-SX771 is an optical sensor, also known as a photointerrupter, of a slot type and including a logic output. It is used in a wide range of applications, hundreds of which are listed in the EE-SX771 datasheet.

It can be used for object detection, an example being an automated door opener. The mechanism utilises the sensor and its logic output to detect when an object is in the doorway, and then triggers the opening or closing of the door. This type of sensor can also be used in automotive applications such as switch activation or in motor control systems, where the sensor can be used to detect speed or position.

The EE-SX771 is a through-beam type photointerrupter, meaning that the transmitter and receiver must be mounted in a separated housing in order for the sensor to operate. The sensor has an optical power output range of 4mA to 20 mA which enables a good signal-to-noise ratio in various applications. The photointerrupter is triggered by the interruption of light from the transmitter. When the light from the transmitter reaches the receiver, the receiver will output a signal to indicate that light is present. When the light is interrupted, the sensor will output a different signal indicating absence of light

The EE-SX771 also has a wide range of logic functions to choose from. It can be set to operate in "normally open" or "normally closed" mode to indicate the entering of a object. The sensor can also be configured to output either an active low or active high signal. It can also be set to detect the following functions: non-interrupting, the continued presence of an object, the presence of an object for a preset time, and the removal of an object for a preset time.

In addition to the wide range of functions, the EE-SX771 has a number of characteristics that make it a great choice for a variety of applications. It has an operating temperature range of -30 to +100 degrees Celsius and a surge protection capability of 200 V per 1 µs, ensuring reliable operation in harsh environments. It also has a long operating distance of 40 to 100mm, allowing it to operate in a wide range of spaces. The detection area is 5 mm square, meaning that it can detect objects of various sizes, further increasing its versatility.

The EE-SX771 is an excellent choice for a wide range of applications, making it one of the most popular available optical sensors. Its versatility and wide range of functions make it suitable for use in virtually any environment.
