Optical Sensors - Photointerrupters - Slot Type - Logic Output

OPB462N11 is a kind of slot-type logic output photointerrupter. It combines a gallium-arsenide infrared emitting diode gate and a NPN silicon phototransistor detector, which provides the solid-state typically-open, normally-closed, and other expression capabilities.

Application Field

OPB462N11 has a wide range of applications in the industrial field. It is mainly used for position and alignment detection, presence or absence of objects, and detection of infinite positions. In the medical industry, it is used to detect the movement of parts of medical instruments, as well as the trigger control of the operation of the equipment. In the production line industry, it can be used for counting, detecting whether the conveyor belt is operating normally, or controls the start and stop of the conveyor belt.

Working Principle

OPB462N11 utilizes optical signal transmission, which is output through the transmission of light to detect the presence or absence of objects. When the gap between the emitter and the detector is covered or separated, the detector output changes. This principle is applied when PNP and NPN detectors are connected in parallel and in series with a circuit, which allows them to detect the presence or absence of objects in the slot. OPB462N11 has a high switching frequency that allows it to recognize very small objects passing through, or when the width of the gap between the emitter and the detector is very small. It also has a wide range of operating voltages, between 3 - 80V, and can provide logic output control between 10m A to 30m A. In addition, OPB462N11 has an insensitivity to colour due to its stabilized photocurrent, allowing it to work even if the light condition is changed.

Conclusion

OPB462N11 is a type of slot-type logic output photointerrupter widely used in the industrial field. It has a wide range of applications including position and alignment detection, presence or absence of objects, and detection of infinite positions. It mainly utilizes optical signal transmission, which is output through the transmission of light to detect the presence or absence of objects, and has a high switching frequency, operating voltage range, and insensitivity to colour.
