Optical sensors are devices designed to detect light. The purpose of these sensors is to recognize or detect a specific object present in the field, even when the environment is constantly in motion. Many industrial and commercial applications of these sensors require reliable operation and high performance. In order to support these needs, electronic component manufacturers have created a wide range of optical sensors, such as PhotoInterrupters, Slot Type and Logic Output.

The EE-SX871A is an example of a Slot Type, Logic Output, PhotoInterrupter optical sensor manufactured by Omron. The main features of this device include: 50kHz operation frequency; 1 million switching cycles; 5.4mm slot width; and 3V operating voltage.

The EE-SX871A is mainly used in applications such as consumer appliances, toys, printer and medical equipment. It is also useful for applications involving operations with precise calculations, such as automobile and photoelectric shaft recorders. Specifically, the EE-SX871A is capable of accurately detecting various objects, such as expansion bolts, projections or elevations, as well as producing a logic output in response to the interruption of the light beam.

The working principle of the EE-SX871A can be explained as follows. The light emitter, which is composed by an infrared LED and an optical slot, emits a light beam. This beam, in turn, is detected by the phototransistor. The interruption of the light beam due to an object being present in the field triggers the phototransistor, producing a logic output.

The EE-SX871A has a very compact size and light weight. This makes it ideal for applications in restricted spaces, as these can be easily incorporated into a restricted installation. Additionally, the device can be used in a wide range of environmental conditions, such as cold, vibration, dust, water and temperature extremes.

Besides having a large market application area, the EE-SX871A is highly reliable and offers a long life span. Moreover, the device can easily be connected to a controller, allowing for remote control of the device. This provides a user with flexibility and convenience.

In conclusion, the EE-SX871A offers a good combination of features, making it a great choice for applications requiring small size, reliable operation and accuracy. It is a fast and reliable solution for detecting objects in various applications, and is especially useful for applications involving precise calculations. Its compact size and high reliability provide users with a device that requires a minimal amount of installation and maintenance.
