Optical sensors, also known as photodetectors, are devices used to detect light radiation and convert it into a proportional electrical signal. Photodetectors are typically used in optical communication and measurement applications. Photointerrupters are one type of photodetector, and slot type photointerrupters utilize a series of slots and a slit to detect the presence or absence of an object. The SF2-EH28-N is a type of logic output slot type photointerrupter, which is typically used in position sensing and motion detection applications.

SF2-EH28-N Application Field

The SF2-EH28-N is a type of slot type photointerrupter logic output which is typically used in applications such as position sensing, motion detection, and instrumentation. It is well-suited for these types of applications because of its high precision and reliability and its ability to detect objects accurately even in noisy environments. It is also widely used for motor control applications as it can detect the presence of rotating objects quickly and accurately.

In addition, the SF2-EH28-N is also widely used for medical equipment such as patient beds and surgical aides. The ability to detect objects accurately and reliably allows for precise manipulation of medical equipment for safety and accuracy. Other applications for the SF2-EH28-N include amusement park ride control systems, material transport systems for industrial and manufacturing applications, and robotics.

SF2-EH28-N Working Principle

The SF2-EH28-N utilizes a series of filter slots and a slit to detect the presence or absence of an object. The filter slots are located on opposite sides of an LED illuminated slit which is positioned in the center of the photointerrupter. When an object passes through the slit, part of the light emitted from the LED is blocked, thus creating a reduction in light intensity.

The reduction in light intensity is detected by the photosensitive element located on the opposite side of the slit. When the reduction in light intensity is detected, a signal is sent to a logic control circuit, which then sends an appropriate signal to the output. The output signal can either indicate the presence or absence of an object, depending on the type of logic used.

The SF2-EH28-N is also able to detect different objects depending on the size of the slot and the output logic used. The size of the slot determines how large an object can be detected by the photointerrupter, while the logic determines whether the output will indicate the presence or absence of an object. By using different combinations of slot sizes and logic, the SF2-EH28-N is able to detect a wide variety of objects.

Conclusion

The SF2-EH28-N is a type of logic output slot type photointerrupter typically used in position sensing and motion detection applications. It utilizes a series of filter slots and a slit to detect the presence or absence of an object. When an object passes through the slit, a reduction in light intensity is detected by the photosensitive element, which then sends an appropriate signal to the output. Depending on the size of the slot and the output logic used, the SF2-EH28-N is able to detect different objects, making it a versatile device for a variety of applications.
