Optical Sensors are devices that detect a measure of light incident on them, usually in the form of a transmitted or reflected beam. In particular, Photointerrupters are optical sensors that respond to the interruption of a beam of light. These devices are commonly used for sensing the positions of moving parts as well as detecting the passing of objects.Slot Type Photointerrupters are a type of opto-mechanical sensor that uses two opposed photodetectors in a slot through which a light source is placed. When a target passes through the slot, it interrupts the light beam and triggers the output.
The OPB830L51 is an example of this type of Photointerrupter. It consists of an LED light source, an infrared detector/receiver and a NPN output transistor. The LED light source emits a beam of light which is received by the infrared detector. When an object passes through the slit, it interrupts the light beam and the output of the detector changes from the “on” state to the “off” state. The output of the infrared detector is then used to drive a NPN transistor, producing an electrical output signal.
The OPB830L51 is primarily used in industrial and automotive applications such as position sensing, object detection, and motor control. It is designed for use with a wide range of materials such as plastic, metal, and wood, as well as for detecting objects of varying sizes. It is also designed to be resistant to EMI and RFI noise which is common in industrial environments. The OPB830L51 is a versatile and reliable optical sensor for industrial, automotive, and consumer applications.
