Introduction

The OPB350W062Z phototransistor output slot type photointerrupter is an optical sensor used to detect the passage of an object through a slot. The sensor is designed to detect a slot that varies in width from 0.11 inches (2.8mm) to 0.13 inches (3.2mm) and has an operating voltage between 18 and 30 VDC. The output transistor of the photointerrupter activates (saturates) when the object passes through the slot, allowing for the control and monitoring of the presence of the sensed object.

Application Field

The OPB350W062Z photointerrupter is used in a variety of industrial and consumer applications. It can be found in elevators, automatic doors, security systems, and robotics, as well as in various automated assemblies and production lines. As a boolean switch, it is used to detect an object in a slot or between two separate objects, such as a stainless steel bar or a fiberglass bar.

Working Principle

The OPB350W062Z photointerrupter consists of an emitter (LED) and a phototransistor. As an object is passed through the slot, the infrared light source of the emitter is blocked, and the phototransistor is activated, producing an output voltage. When the object is removed from the slot, the phototransistor is deactivated, and the output returns to a low or 0 voltage, indicating that the object has passed. The photointerrupter can be wired in either a "normally open" or "normally closed" configuration.

Conclusion

The OPB350W062Z photointerrupter is an versatile and reliable transistor output slot type photointerrupter designed to detect the passage of an object through a slot. Its robust construction and wide range of operating voltage allow it to be used in a variety of industrial and consumer applications, ranging from elevators and automatic doors to security systems and robotics.
