Optical sensors are used to detect the presence and/or absence of objects or materials, and to measure the distance between them. One type of optical sensor is a photointerrupter, which works by detecting a break of light between two parts of an object. The EE-SX2088 is a slot-type photointerrupter, with a transistor output, that is specifically designed for a wide variety of applications, including noncontact position sensing or object detection.

Description

The EE-SX2088 is a slot-type photointerrupter with a transistor output. It is specifically designed for noncontact position sensing and object detection applications, and can offer reliable detection with high precision and a wide range of operating temperatures. The EE-SX2088 is available with either plastic or metal housing, and is designed with a slender slot, allowing the device to finely detect objects within a narrow space.

Working Principle

The EE-SX2088 operates by using optical coupling between a transmitter and an receiver. The transmitter part consists of an LED and a small coupling window for illumination. The receiver part consists of an integrated phototransistor and a pair of unconnected lenses. When an object passes through the slot, it breaks the optical coupling, causing current to flow between the LED and phototransistor. The current is then converted into an electrical signal which can be used to detect the presence and/or absence of the object.

Applications

The EE-SX2088 is widely used in a variety of applications, including:

• Demand-controlled lighting systems
• Elevator door and gate operations
• Printer activity sensing
• Presence and rotation detection
• Position detection
• Robotic arm or component detection
• Motor speed sensing and monitoring
• Security systems

Features

The EE-SX2088 offers users several noteworthy features, which include:

• Light-weight, slim design: This allows users to easily position the optical sensor on the surface of the object to be detected.
• Outstanding optical coupling: The EE-SX2088 offers an optical coupling ratio of up to 1:200, providing reliable detection even in extreme situations (e.g. low light).
• High and low switching speed range selection: The EE-SX2088 is capable of performing both high and low speed switching, making it suitable for applications which require both higher and lower detection speeds.
• Slim and flexible: The EE-SX2088 is designed with a slim and flexible housing that allows users to precisely detect objects within a narrow space and in tight places.
• Wide operating temperature range: The device can operate within a wide temperature range of -25°C to +85°C.

Conclusion

The EE-SX2088 is a slot-type photointerrupter, with a transistor output, that is specifically designed for noncontact position sensing and object detection applications. It offers a wide range of features that allow users to timely detect and measure the presence and/or absence of objects or materials, making it an ideal choice for many different applications. Its slim and flexible design, in addition to its wide temperature range, make it suitable for even the most challenging environments.
