Optical sensors are sensors which allow devices to work in a variety of light conditions. Photointerrupters are a type of optical sensor that detect the interruption of a light beam by a physical object. The OPB315WZ is a slot type photointerrupter with a transistor output.

Features and Benefits

The OPB315WZ offers a range of key benefits and features, starting with its small size and lightweight design. It has a slot size of 2.92mm and a lead pitch of 0.05mm. The sensor is encased in a black sealant, providing protection from the elements and further enhancing its reliability. The device has been tested to withstand a variety of temperatures and is UL recognized, allowing it to be used in sensitive electronics applications.

Application Fields

The OPB315WZ has a wide range of applications. It is commonly used in motor drive circuits, where it provides pulse width detection and switch control signals. It is also used in position detection applications, such as displacement sensing and motion control. The OPB315WZ can also be used as a light barrier in automotive and industrial applications, where it is used to detect the presence of an object or to detect the presence of a beam of light.

Working Principle

The OPB315WZ works on the principle of photoelectric sensing. It consists of an emitter and a receiver, connected by a gap between them. The emitter emits light which is picked up by the receiver. When an object interrupts the light beam, the receiver does not receive the light and the gap is closed. The gap is detected by an electronic circuit, which then triggers a signal. This signal is used to switch on or off a motor or other device.

Conclusion

The OPB315WZ is a highly reliable and versatile transmissive optical sensor that can be used in a range of applications. It is small, lightweight, and offers excellent protection against the elements. It is commonly used in motor drive circuits, position detection, automotive and industrial applications, and as a light barrier. It works on the principle of photoelectric sensing and can detect the interruption of a light beam by a physical object.
