OPB482T11Z application field and working principle

Photointerrupters are semiconductor sensors which use light to detect the presence of objects. The OPB482T11Z is an example of a specific type of photointerrupter known as a slot type with logic output. This device is designed to detect position, size, and shape of objects and can be used for controlling equipment or as part of a security system.

Application fields

The OPB482T11Z slot type photointerrupters with logic output can be used for a variety of purposes. These devices can be used in industrial settings to control the performance of machinery and to ensure safety by detecting the presence of objects. They can also be used in security systems to detect intruders or unwanted visitors. In addition, they can be used to detect the presence of objects for metering, positioning, and counting purposes. In general, the OPB482T11Z can be used in any situation where the detection of an object\'s presence or position is required.

Working Principle

The working principle of the OPB482T11Z photointerrupter is based on the transmission of light from the emitter and the detection of this light by the detector. When a light-transmitting object passes between the emitter and detector of the photointerrupter, the light is interrupted, which the device uses to detect the presence of the object. The device then triggers a logic output signal, which is used to notify the user that an object has been detected.

The emitter of the OPB482T11Z photointerrupter is typically an infrared LED and the detector is typically a photodiode or a phototransistor. The optics of the device are designed to limit the field of view to the specific slot shape. This ensures that only light-transmitting objects passing through the slot in the exact orientation will be detected. The device also has a hysteresis control, which maintains a stable output signal for objects which pass through the slot.

Conclusion

The OPB482T11Z slot type photointerrupter with logic output is a versatile device which can be used in a variety of applications. It is designed to detect the presence of objects by utilizing an infrared LED emitter and a detector, and can be used for position, size, and shape detection. It has a limited field of view to ensure that only objects of the exact shape and orientation are detected. Furthermore, the device also has a hysteresis control to maintain a stable output signal when objects are detected.
