Optical sensors have been used in a wide variety of applications, ranging from industrial automation to medical diagnostics. The OPBA303 is an example of an optically-sensitive component designed specifically for sensing gap, slot, or notch type objects. It has a sensing range of up to 10mm, and is available with either a transistor or a solid-state relay output.

The OPBA303 is composed of an infrared light-emitting diode (IRED), an integrated reflector, and two phototransistors that are housed within a black housing. The IRED emits a beam of light perpendicular to the device, which is reflected off the integrated reflector and onto the phototransistors. When a gap, slot, or notch type object passes between the IRED and the integrated reflector, the light beam is interrupted, and the phototransistors are blocked. This then triggers the output stage of the device – either a transistor or a solid state relay.

The OPBA303 is specifically designed for connecting with machinery and is particularly suitable for industrial applications with its high switching speed and noise immunity. The device is able to detect objects up to 10mm away – a distance much greater than most other optically-sensitive components. It has a fast response time of 2 ms, is RoHS compliant, and can operate in temperatures ranging from -20°C to +60°C. As such, it is capable of providing reliable performance in harsh and/or humid environments.

The OPBA303 is also extremely versatile, as it can be used for sensing slot type objects as well as gap objects. It has a high level of flexibility, as it can be installed either upside down or right side up, and can even be mounted on the side of a moving object. Additionally, the device has the flexibility to switch between either a transistor or a solid state relay output.

Overall, the OPBA303 is a highly reliable and versatile optically-sensitive component, well-suited for detecting gap, slot, or notch type objects in industrial applications. Its fast response time, high switching speed, RoHS compliance, and noise immunity make it an ideal choice for connecting with machinery. Furthermore, its ability to switch between a transistor or solid-state relay output gives the device great flexibility and makes it a reliable choice for a wide range of applications.
