Optical sensors are devices that detect and measure radiation from visible, infrared, and ultraviolet sources. Photointerrupters are one type of these sensors and are commonly used in a wide variety of applications. The SF2-EH20-N is a slot type Photointerrupter with a logic output. This article will discuss its application field and working principle.

The SF2-EH20-N is a type of slot type Photointerrupter. It consists of an infrared emitting diode (IRED) and a phototransistor that measure radiation from visible, infrared, and ultraviolet sources. The slot is designed to appose the two components when a light beam passes through the slot.

The SF2-EH20-N is primarily used in industrial applications for security sensing, proximity sensing, robotic navigation, and power control. For security sensing, the Photointerrupter can be used to detect objects entering or exiting a defined area. In proximity sensing applications, the Photointerrupter can be used to prevent objects from entering a certain area. For robotic navigation, the Photointerrupter can be used to measure the distance between two objects and help robots to navigate around obstacles. Additionally, the Photointerrupter can also be used in power control applications to measure current and electric power.

The SF2-EH20-N is able to detect a wide range of radiation from visible, infrared, and ultraviolet sources. In addition, the slot size is adjustable so that it can detect light sources in various forms and orientations. Furthermore, the Photointerrupter has high sensitivity and fast response times, making it suitable for applications that require quick reactions.

The SF2-EH20-N works by emitting an infrared light beam from an IRED, which then passes through the slot and is detected by a phototransistor on the other side. When the light beam is interrupted, the phototransistor triggers a logic output signal. This signal can be used to trigger an action or process.

In conclusion, the SF2-EH20-N slot type Photointerrupter with its logic output provides an effective and accurate way to detect a wide range of radiation source from visible, infrared, and ultraviolet sources. This makes it ideal for industrial applications such as security sensing, proximity sensing, robotic navigation, and power control. Furthermore, the sensitivity and fast response times make it suitable for any application requiring quick reactions.
