Optical Sensors are often used as instruments to convert optical information into electrical signals. Photointerrupters are one type of optical sensors that are available in different models and use different technologies. The OPB842L55 is a slot type photointerrupter with a transistor output, which is utilized in a variety of applications.
The OPB842L55 consists of an infrared emitting light source coupled with a Phototransistor that are mounted side-by-side in a black nylon, 6-pin, DIP housing. When an object is placed between the emitter and the phototransistor, the infrared light from the emitter is blocked and the phototransistor is activated. The OPB842L55 provides a switching voltage of 5V when it is powered up to detect the presence or absence of an object in its sensing range.
The working principle of the OPB842L55 is simple: when the light emitting diode (LED) emits infrared light, it is received by the phototransistor. When something moves between the LED and phototransistor and blocks the light, the phototransistor turns off and no electrical current flows through it. If no obstacle is present in the detection range, the phototransistor is active and electrical current flows.
The OPB842L55 is used in wide range of applications where the detection of an object or presence is required. This device can be used in automatic door openers, position sensing, level sensing, material handling systems, machine automation, electronic compass, proximity sensing, and speed monitoring systems. It is also used in many consumer products such as vending machines, copy machines, microwave ovens, toys, and gaming systems.
The OPB842L55 is designed to be easy to install and use with minimal maintenance. It is a low cost and reliable optoelectronic device with high optical sensitivity, allowing it to detect a wide range of objects. The device also has a fast response time of less than 1 msec, making it suitable for a variety of applications requiring fast response times.
In summary, the OPB842L55 is a Slot Type Photointerrupter with a Transistor Output, which is used in a variety of applications to detect the presence or absence of an object. It has a fast response time and is easy to install and use, making it a versatile and reliable optoelectronic device.
