Optical Sensors - Photointerrupters - Slot Type - Transistor Output - OPB832W51Z

The OPB832W51Z is a slot sensor optical sensor made by Optek Technology, Inc. It is a type of photointerrupter type optical sensor, with the purpose of detecting the presence or absence of objects passing into its 30 mm sensing range. It works by emitting an infrared light, which will then be interrupted by any object passing in front of it. It is used in a wide variety of industrial sensing applications such as machine vision, manufacturing, robotics, logistics, and more.

Functionality

The OPB832W51Z optical sensor utilizes a high-efficiency optical design with a collimated 450 nm LED light and integrated phototransistor, which together allow it to accurately detect and identify the presence of objects up to 30 mm away. This is then triggered by an output signal consisting of a high and low state, the output changes based on the interruption of the light beam by an object. This makes it a very versatile and reliable solution for an easy detection application.

Features

The major features of the OPB832W51Z include its compact size, 30mm sensing range, and high-speed response time of 0.5ms. It also features an operating voltage ranging from 4.5V to 5.5V, which can be used with both PNP and NPN transistors. The sensor is also capable of operating in both normally-open or normally-closed configurations. This allows for a wide range of application possibilities and custom operation.

Applications

The OPB832W51Z can be used in a wide range of industrial applications, such as:

• Machine vision systems
• Manufacturing equipment
• Logistics
• Robotics
• Automatic sorting systems
• Surface inspection

Working Principle

The OPB832W51Z utilizes an integrated phototransistor design which can detect the presence of objects up to 30mm away when illuminated by its infrared LED. When an object interrupts the beam of light, the output changes to a low state, this can be used to detect, count, time, differentiate, identify, or otherwise measure the presence or absence of objects. Depending on the configuration, the output can be high when an object is present, or low when an object is absent.

Conclusion

The OPB832W51Z is an ideal optical sensor for an easy detection application, with features such as its compact size, 30mm sensing range, and high-speed response time, it is the perfect choice for a wide range of industrial sensing applications. Its integrated phototransistor design and transistor output make the OPB832W51Z a reliable and versatile solution for even the most demanding of application requirements.
