Optical Sensors are electronic components that detect and respond to light within a specific wavelength. Photointerrupters are one type of optical sensor that uses a light-sensitive element and a trigger photodetector in order to create a digital signal when a light source of a particular wavelength is interrupted. Slot Type photointerrupters are designed to detect the presence or absence of an object by detecting the interrupt of a beam of light. The SF2-EH56-N is an example of a slot type photointerrupter.

The SF2-EH56-N is an integrated optical module consisting of a light-emitting source and a trigger photo detector, working together in an IC chip package. The light-emitting source is a High-Output LED while the trigger photodetector is a high breakdown voltage photodiode. The SF2-EH56-N package is designed with a slim slim slot form factor that makes it suitable for applications requiring high density space. It features a wide operating temperature range of -40°C to +85°C and is ESD protected for increased reliability.

The primary application field of SF2-EH56-N is being used for simple detectors in compact and dense packaging that require a fast response time. Examples of such applications include automated and automatic door opening systems, alarms, guard security systems, automatic scissors, and low-cost applications depending on presence or absence detection.

The working principle of the SF2-EH56-N is as follows. It uses a built-in output transistor to switch the output between LOW and HIGH states when the LED is blocked by an object. The LED emits a light beam and when the beam is blocked there is an output. When the beam is not blocked, there is no output. A built-in Zero-Cross function allows the system to detect and accurately sense the direction of an object even when they are moving in very slow speed. Furthermore, the SF2-EH56-N features a short switching time (<10 µs, max) for improved accuracy, reliability, and response time.

In conclusion, the SF2-EH56-N is a slot type photointerrupter that is designed to detect the presence or absence of an object by detecting the interrupt of a beam of light. It is suitable for applications requiring high density space, has a wide operating temperature range and is ESD protected. Its primary application field is in applications such as automated/automatic door opening systems, alarms, guard security systems, automatic scissors and low-cost presence/absence detection. Its working principle consists of using a built-in output transistor to switch the output between LOW and HIGH states when the LED is blocked by an object.
