Optical sensors are widely used in automation and industrial control systems because of their advantages, such as small size, wide range of operation, good sensitivity, strong filtering performance, and reliable operation.Photointerrupters, one type of optical sensors, are also known as slot type photodetectors and operate on the principle of polymer optical waveguides. Photosensitivity is obtained through the changes in the intensity of the light which passes through a gap in the waveguide. The EE-SX674R is a logic output photointerrupter.

The EE-SX674R has the following features:

• Typical rise/fall time of 0.2 ms
• Optimized breaking current of 4 mA
• Insulated Peek plastic body
• With solder landing
• With axial lead

The principle of operation of the EE-SX674R is simple. It operates in a polarized light field. When an object passes through the slot, light is reflected off the object and is detected by the device. The reflected light causes the EE-SX674R to output a logic-level digital signal. The output is either high (in phase with the input) or low (reverse phase from the input). This output is then used as an input signal in an automation system.

The applications of EE-SX674R include paper feed control, machine counting, gate release, machine production monitoring, bar code readers, etc. In paper feed control, the EE-SX674R is used to detect the presence of a sheet of paper as it passes through the slot. The device then triggers the next phase of the paper feed process. In counting applications, the EE-SX674R is used as a sensor to count objects as they pass through the slot. In a gate release system, the EE-SX674R detects the movement of a gate and expands or retracts the gate as required.

The EE-SX674R has a low-cost, yet reliable design making it suitable for a wide variety of automation applications. Its design is also simple making it easy to install and maintain. It is capable of withstanding harsh environmental conditions and temperatures of up to 80°C making it suitable for industrial use. Additionally, the EE-SX674R is RoHS compliant.
