The OPB483L11 is a slot type photointerrupter logic output optical sensor designed to detect the presence of objects within an infrared light beam. The device includes an infrared emitter and a silicon photo-transistor detector. When an object interrupts the beam, the signal output is changed from the detection state to the no-detection state or vice-versa.

The OPB483L11 optical sensor is used mainly for industrial, medical, and consumer applications. This device is suitable for applications such as object counting, cylindric presence/absence detection, assembly line detection, and positioning. In addition, the device can be used for presence detection in machines, motor control, and in vehicles.

The main components of the OPB483L11 include an infrared emitter, a silicon photo-transistor detector, a filter module, and a logic circuit. The infrared emitter sends an infrared light beam which is then blocked or allowed access to the silicon photo-transistor detector depending on the presence or absence of an object interrupting the path. The filter module is used to reduce any stray light resulting from objects outside the detection range. The logic circuit, which is optically isolated from the sensor, converts the photo-transistor output into a TTL compatible logic output.

In operation, the OPB483L11 optic sensor emits an infrared light beam, and the photo-transistor detector is triggered when an object interrupts the light beam. When the object is absent and the beam is uninterrupted, the output will be in a stable detection state. However, when the object is present and interrupts the beam, the output will change from the detection state to the no-detection state. The different output states are then converted by the logic circuit into a TTL compatible logic signal which can be integrated into any application requiring the presence or absence of an object in a defined space.

The OPB483L11 has a TTL compatible logic output with a low active output, which makes it easy to interface with a wide variety of systems. The device has a detection area of up to 65mm and a 0.6mm clearance distance between the infrared emitter and the photo-transistor detector. The device is RoHS compliant, and a wide range of operating temperatures, from -25°C to +85°C, makes the device suitable for many industrial and consumer applications. The OPB483L11 has a wide supply voltage range of 3V to 24V and is available in a variety of styles, from the SOP-4, SSOP-4, and through-hole options.

The OPB483L11 is an ideal solution for presence or absence detection, object counting, cylindric presence/absence detection, assembly line detection, or positioning applications. The device is easy to integrate into any control or monitoring application with its TTL compatible logic output, and is suitable for use in a wide range of temperatures, making it ideal for industrial and consumer applications.
