The OPB973N51 is a photodetector based on a push-pull output photointerrupter. It is used for triggering signals in a wide range of applications including position detection, counting, motion sensing, and more. It is capable of detecting the presence or absence of an object in its field of view and transmitting a corresponding output signal.

The OPB973N51 belongs to the Optical Sensors – Photointerrupters – Slot Type – Logic Output category. It is designed to be extremely sensitive and highly stable, allowing its use in many different applications. It consists of a light-emitting diode (LED) and a phototransistor, both mounted in a small 4-pin package. The output can be used to directly control a variety of electronic devices ranging from solenoids and relay coils to logic circuits.

The OPB973N51 is typically used to detect the presence of a target or object, such as a reel of label stock when used in a labeling machine or parts on a production line. Its push-pull output provides a precise voltage level to the target circuit. When there is no object in the field of view, the output remains at a low level. When an object or target is detected, the output voltage is switched to a high level.

The OPB973N51 has a range of detection distances up to 50mm and requires a light source at the emitting end. It is powered by a supply voltage between 4.5 and 24 volts. The following features can be adjusted or tuned: sensitivity, logic output pull-up or pull-down, pulse duration on/off, and logic threshold voltage.

The OPB973N51’s small size and easy installation make it a preferred choice for a wide range of applications. Its high sensitivity means it can detect very small objects as well as large ones. Its durability and long operating life make it a reliable detection device for many different types of industrial and consumer applications.

The OPB973N51 is a versatile, inexpensive photointerrupter that is used for a wide range of applications such as position detection, counting, motion sensing, and more. It is ideal for applications that require reliable and accurate detection of objects. It is designed to be easy to install and provides precise voltage levels for a variety of electronic devices when an object is detected.
