Introduction

The SF2-EH32-N is an optical sensor, specifically a slot-type photointerrupter, with a logic output. Optical sensors are electronic devices that are activated when light gets blocked or interrupted. In the case of the SF2-EH32-N, this includes light being blocked from a LED being interrupted in a slot type arrangement.

Applications & Working Principle

The SF2-EH32-N is broadly used in applications that require sensing and detection. One particular application is in industrial machinery automation, usually found in factories, where robotics use sensors to detect when a moving object or material has passed a specific point. In addition to this, the SF2-EH32-N are also commonly used in measuring systems and equipment for staging and positioning.

The SF2-EH32-N works within two specific principles. Firstly, the two components, which are a LED (Light Emitting Diode) housed within an optical pipe, and a phototransistor housed within an optical slot, work together within a closed circuit.Secondly, light from the LED is projected to the phototransistor, thus allowing the flow of current. When something interrupts this light flow, it causes a break in the current. This leads to the logic output of the SF2-EH32-N detecting the break and activating, thus resulting in the desired effect.

Conclusion

The SF2-EH32-N is an optical sensor, specifically a slot-type photointerrupter, with a logic output. It is a versatile type of sensor with a wide range of uses in various sensing and detection applications. Its two-component design consisting of a LED and phototransistor housed within an optical pipe and optical slot respectively, makes it able to detect when light has been interrupted and cause the required logic output.
