OPB982N55

The OPB982N55 photointerrupter is a slot type optoelectronic device that utilizes a Logic Output system to detect the presence or absence of an object within the sensing range. This device uses reflective and transmissive Light Sensing technology to detect the presence or absence of a target object, such as a paper, card or other material. The OPB982N55 photointerrupter is an opto-sensor that uses a logic (low current, low voltage) output system to detect the presence or absence of an object within the sensing range.

The OPB982N55 is an optoelectronic device with an array of two phototransistors, which are the heart of the device. These phototransistors act as two logic outputs; these outputs help to switch the output state of the device when an object placed in its sensing range. The device uses a variety of lighting and sensing techniques such as reflective, transmitted, and interrupted light. The output of the device is a logic level voltage that can be interfaced to various types of external circuitry.

The OPB982N55 is a wide use device that has been used in a variety of applications such as assembly monitoring, palletizing, sorting, counting, and labeling machines, as well as automotive assembly, semiconductor equipment, and packaging machines. The device has also been used in bar-code readers, automotive intrusion detection systems, vending machines, and industrial robots.

The working principle of the OPB982N55 is to detect a change in the light within the sensing range. When the object passes through the sensing range, the output of the device is changed. In the absence of an object, the output remains low, while in the presence of an object, the output will switch to a higher state. This switching is achieved without any extra power being supplied to the phototransistors after the object is removed, allowing for a power saving after detection. The output signal is provided as a logic level voltage, making it ideal for use as an output signal of an external circuit.

In addition, the device features an integrated voltage regulator and over/under voltage protection, making it capable of operating with a wide range of input voltages. It also provides reverse polarity protection, meaning that it can be used in applications where the input voltage supplied to the device is reversed. The device also has an Auto-reset feature, meaning that it will reset itself automatically after detecting an object.

In conclusion, the OPB982N55 is a versatile optical sensor, designed for detecting the presence or absence of an object. Its logic output system makes it an ideal choice for applications such as assembly monitoring, palletizing, sorting, counting, and labeling machines, as well as automotive assembly, semiconductor equipment, and packaging machines. It can be used in different environments and applications, due to its low power consumption and its wide input voltage range. Additionally, the device features an integrated voltage regulator and protection functions, making it robust and reliable.
