Optical sensors are a type of sensor incorporating a light source and a photodetector and measuring light that is reflected or transmitted from an object. They are used in many different applications, from automotive and mobile devices to consumer products and industrial production. Photointerrupters, specifically, are used for measuring the width of slots or gaps, and sensing the presence of an object blocking the light emitted by the photointerrupter. The EE-SX405 model from Omron Corporation is a slot-type photointerrupter with a logic output (PNP), designed for applications that require accurate position sensing of electrical contacts, switches, or mechanical objects.

The EE-SX405 utilizes reflective photointerruption sensing technology, which is the interruption of light when an object passes through the gap of the photointerrupter. This gap, usually between 0.5mm and 2mm in width, is detected by the interrupting of the light emitted by the photointerrupter\'s light source at a certain rate. In this way, the EE-SX405 is able to accurately measure changes in position and speed of electrical contacts, switches, and other moving objects.

The EE-SX405 consists of two components: a light source and a photodiode. The source is usually an infrared LED, and the photodiode is designed in a special format so that the signal it produces corresponds to the presence or absence of an object. When an object passes through the gap of the photointerrupter, the light source is interrupted and the signal sent to the photodiode is blocked, resulting in a logic low. When the gap is clear, the photodiode receives the light and sends a logic high. This output is usually a PNP-type logical output.

The EE-SX405 is designed for use in automation systems for measuring positional data and detecting object movement, and is available in a variety of package styles for various applications. It is available in several resolutions, including a 2mm-wide gap, 3mm-wide gap, 4mm-wide gap, and 5mm-wide gap. Its features include a wide operational voltage range, a long life (up to 100 million switching cycles), and a fast response time (2ms or less). The EE-SX405 is also compatible with a variety of power sources, including 5V DC, 12V DC, 24V DC, and 48V DC.

The EE-SX405 is a reliable and versatile optical position sensor that can be used in a variety of applications. It is a cost-effective solution for accurate position sensing in industrial and consumer products, such as automated assembly equipment, motor control systems, and coding and labeling machines. Its wide gap options and response time make it ideal for use in applications where accuracy and speed are of paramount importance. Additionally, its user-friendly design allows for easy installation and setup.
