OPB704 is an analog output reflective optical sensor which is manufactured by Banner Engineering Corporation. This type of optical sensor is designed for a variety of applications and uses a number of different techniques to detect objects. It has an integrated amplifier and an adjustable threshold setting for sensitivity. The OPB704 uses a photosensitive silicon photocell to detect an object or reflectivity change in the environment. The sensor can be programmed to behave in one of two modes, active or passive. In passive mode, the sensor will detect changes in the ambient light level and can be used to discriminate between light and dark surfaces. In active mode, the sensor will detect changes in the reflectivity of an object and can operate in both ambient light and total darkness.

The OPB704 is ideal for applications where the detection of a reflective surface or object is required. This could include, but is not limited to, factory automation, robotics, and assembly line applications. The reflective sensor can detect objects of various shapes and sizes, including round, square, rectangular, and curved surfaces. It can also be used in industrial environments as a safety guard, light curtain, or non-contact position sensor.

The working principle of the OPB704 is based on the concept of total internal reflection. The sensor contains an integrated amplifier which amplifies the reflected signal. This signal is then compared to an adjustable threshold voltage set by the user. If the signal exceeds the threshold, an output signal is generated and can be used to trigger an event. The adjustable threshold feature allows the user to configure the sensor to detect objects of different sizes and shapes.

The OPB704 has a 10 to 60-Volt DC operating voltage range, and is rated IP67 for dust and water protection, making it suitable for a variety of harsh environmental conditions. Additionally, the sensor is RoHS compliant and compliant with UL, CE, and CSA safety regulations. In addition to its environmental protection features, the OPB704 also has a number of different output options available, including AC, DC, transistor, thyristor, PNP, and NPN.

The OPB704 is a highly versatile reflective optical sensor that can be used in a variety of applications, from industrial to commercial. With its integrated amplifier and adjustable threshold sensitivity setting, the OPB704 is an ideal choice for detecting objects and reflects of varying sizes and shapes in both ambient light and total darkness.
