Introduction

Optical Sensors - Photointerrupters - Slot Type - Transistor Output, specifically the EE-SV3-GS series, provide a precise and convenient measure of data regarding the interruption of light. This precision allows for calculations of how long the interruption lasts and how much light is emitted from the source into the environment. The working principle of this type of device and its general application field is further explained in this article.

Optical Sensors - Photointerrupters

Optical sensors are devices that detect and measure changes in light within a given environment. Photointerrupters are a special type of optical sensor that interrupts light from one source, changes its characteristics, and then continues the path of the light elsewhere. This interruption serves as functional feedback for applications requiring a sense of distance or presence of a foreign object.

Slot Type - Transistor Output

The EE-SV3-GS series utilizes slot type and transistor output for its level of functionality. Slot type measures the interruption of the light source and transistors output measure the amount of light that remains after the interruption. Slot type has an advantage in that it is able to measure interruptions with greater accuracy due to its higher resolution. The outputs from the transistors offer a reading of the light source\'s power output before the interruption.

EE-SV3-GS Working Principle

The EE-SV3-GS utilizes a two-channel optical system to measure the presence and duration of an interruption. At the source, an LED emits light which shines through an open slot on the sensor. The light is detected when it reaches the light-sensitive transistor. The transistor switches away from the LED in response, signalling a positive reading of the presence of an object. The duration of the interruption is determined through two types of signals: the RC circuit timer and the EMF detector. The RC circuit timer measures the time taken between the interruption and the reset of the circuit. The EMF detector measures the amplitude and frequency of the irradiated waves.

EE-SV3-GS Application Field

The EE-SV3-GS is designed for applications in various industries, such as Home and Building Automation, Manufacturing, Automotive, and others where reliable sensing information is needed. Additionally, its two-element system allows for a variety of control applications, such as in automated folding and manufacturing processes, as well as other services such as elevator control systems.The EE-SV3-GS has a number of features that make it attractive for use in many control systems. These include its small size, low power consumption, high switching speeds, and robust durability. Additionally, its accuracy and flexibility make it a good choice for a variety of sensing applications, including industrial robotics, food handling and packing processes, and automated cutting operations.

Conclusion

The EE-SV3-GS series provides a reliable and accurate measure of light detection in applications requiring a sense of presence or distance of a foreign object. It has a variety of features that make it suitable for use in many industrial and consumer applications. In addition to this, its slot type and transistor output support more accurate calculations than most other similar devices. As such, this device is an excellent choice for efficient and precise sensing.
