Optical sensors are specialized electromagnetic or energy transduction devices used to detect or measure light. They are generally made up of a light source and a sensing element, both of which are connected to an electrical interface for response. Photointerrupters, such as the OPB667N, are special types of optical sensors that detect the interruption or presence of light in a slot or gap. They are most commonly used in automated machinery and robotics.

The OPB667N photointerrupter is a slot-type logic output optical sensor that has the advantage of providing an electrical signal that is directly proportional to the light interruption. This device consists of an infrared LED and a NPN phototransistor in a one-piece plastic housing. The slot-type design allows the LED and phototransistor to be aligned relative to each other and the presence of light in the gap detected with high sensitivity.

The operating principle of the OPB667N is simple. When light is interrupted in the gap, the output of the phototransistor will change accordingly. The photocurrent generated by the phototransistor provides voltage feedback to the LED, which brings the current output to a stable state. When the LED is activated, the photocurrent decreases the output voltage, triggering a signal that is sent to the external circuit.

The OPB667N photointerrupter finds application in a variety of industries, including automotive, medical and consumer electronics. It is used for position sensing and control in automated machinery, for example, in the assembly and machining of parts. It can also be used for detection and timing applications in robotics. In addition, the sensor is often integrated into consumer electronic products, such as digital cameras and scanners, to ensure precise timing and control.

The OPB667N photointerrupter is a small, compact device that is easy to install and use. It features a wide operating voltage range, high reliability and long service life. Additionally, the device can detect even small changes in light, making it suitable for a variety of applications.

In conclusion, the OPB667N photointerrupter is an efficient and reliable optical sensor that is widely used in the automation and consumer electronics industries. With its easy installation, wide operating voltage range, high reliability and sensitive detection of light, the OPB667N is a versatile and cost-effective solution for a variety of applications.
