Optical Sensors are devices that detect the presence or absence of light. Photointerrupters are a type of optical sensor, and slot type photointerrupters can detect the difference between a lighted slot and dark slit. The EE-SX671P slot type photointerrupter is a logic output type that has a wide range of applications. This article will discuss the EE-SX671P application field and working principle.

The EE-SX671P is a self-contained, miniature 6x3x2.7 mm slot type photointerrupter module with logic output, with a longer detection distance of 5 mm and a higher output current of 30 mA. It is compatible with any of three wavelengths: red, infrared and ultraviolet, and its precise optical pattern and powerful output make it ideal for applications involving detection of long objects, features, and minute segments. It is also suited for Ultra-High Frequency (UHF) RFID tag applications.

The EE-SX671P contains an infrared LED, a phototransistor, and a Schottky barrier diode (SBD), all contained within a single module. The EE-SX671P is available in either an open collector output or a complementary output configuration. When a metallic object is placed in front of the detection window, a high-side signal is generated and the output voltage is at high level. Upon removal of the object, the low-side signal is produced and the output drops to low level. The Schottky barrier diode (SBD) prevents reverse current flow.

The EE-SX671P is be used for paper feeding, picking, and punching applications. It can detect the presence and position of small parts, letters, and forms passing through a chain. Its high-speed signal transmission helps reduce the number of sensors needed in paper transport machinery. The output signal may be amplified for more sensitive detection by external circuits, and the EE-SX671P can be used with protective sleeves for improved accuracy and extended service life. The EE-SX671P can also be used in RFID tags with a 50 kHz distance measuring system.

In conclusion, the EE-SX671P is a high-performance logic output slot type photointerrupter module that is widely used in paperfed machines, picking and punching machines, RFID tags, and many other applications. Its long-distance detection, high output current, precise optical pattern, and powerful output make it ideal for a variety of applications. With this in mind, it is clear that the EE-SX671P is an essential tool for designing either simple point-of-light or longer paperfed, picking, and punching applications.
