Optical Sensors are devices that detect physical changes occurring in their environment and transform them into electrical signals. Photointerrupters are the most common type of optical sensors, typically used in automation machines. They have the ability to detect abrupt changes in light, such as when the beam of a visible laser light is broken. OPB696BZ is a type of photointerrupter specifically designed for slot type applications, and it utilizes a logic output instead of a regular LED output.

Working Principle

OPB696BZ works by sensing the presence of a supposed object or gap between two points when it passes through the slot. It has a sensing distance of 5mm and this means that if the object passes closer than that, it will be detected by the interrupter. When an object is detected, the interrupter then sends a signal to the output device for further actions. The output is a single channel device, which is normally programmed to respond to either a short or a long pulse, depending on the desired result.

Applications

Since it has a relatively long sensing distance and a logic output, OPB696BZ is often used for angular measurement, element counting, and presence/absence detection. Its compact size makes it suitable for use in small automation machines and sensing applications. Some of the most common applications include conveyors, packaging machines, metal detectors, bottling systems, and sensors in automated machine tools.

Other applications include optical sensing of paper/cardboard, clothing, and food products to help detect flaws or discrepancies in their quality. In industrial applications, it can be used to detect momentary/accidental contact with refrigerant pipes, thereby helping to avoid any potential danger.

Advantages

OPB696BZ has a number of advantages over other photointerrupters. Firstly, its long-range sensing distance enables it to detect objects from farther away, reducing the amount of adjustment required in setting up machinery. Secondly, its robust and easy-to-use logic output makes it easier to control output devices. Thanks to its small size, it can also be easily integrated into existing devices, allowing them to benefit from improved sensing capabilities.

Furthermore, as it operates at a frequency of up to 10 kHz, it can easily detect fast-moving objects. Lastly, the device is RoHS compliant, making it suitable for use in applications that require environmental protection.

Conclusion

OPB696BZ is an advanced photointerrupter designed for slot type applications. It has a long sensing distance and a logic output, making it suitable for applications such as angular measurement, element counting, and presence/absence detection. It is compact in size and operates at a frequency of up to 10 kHz, enabling it to detect fast-moving objects. It is also RoHS compliant, making it suitable for use in applications that require environmental protection.
