Optical Sensors offer a comprehensive range of solutions for a wide range of applications and are available in a variety of types, such as Photointerrupters, Slot Type, and Logic Output. One such type of Photointerrupters is the OPB992N51 from Omron, a widely used and highly reliable Optical Sensor for detecting the opening and closing of switches and other objects. Here, we will discuss its application field and working principle.

The OPB992N51 is a slot type, logic output Photointerrupter that detects the presence or absence of objects. It features a high-intensity IR LED and an NPN phototransistor sensor, and is available in a variety of package sizes, from 6 mm to 10 mm. It offers a wide operating voltage range of 5 to 30 V, as well as low-current consumption, making it ideal for battery-powered equipment. The OPB992N51 is designed for use in a number of applications, including security systems, home automation, industrial automation, access control, and remote sensing.

The OPB992N51 is composed of two sections - an IR LED and an NPN phototransistor sensor. The IR LED is a light emitting diode that emits infrared radiation when current is applied. This radiation is then detected by the NPN phototransistor sensor, which converts the radiation into an electrical signal. When a switch or object interrupts the flow of infrared radiation, the phototransistor sensor will switch state, sending a low logic output to the electronics device.

The OPB992N51 also features a number of advantages, including a wide operating temperature range of -40°C to +85°C, immunity to electromagnetic interference, and a long operating life of up to 100,000 executions. Additionally, it has a fast response time of less than 10 μs, and a high OFF-state output current of 10 mA, making it an ideal choice for a wide variety of applications.
