OPB375T55

Optical Sensors - Photointerrupters - Slot Type - Transistor Output

The OPB375T55 is an optoelectronic device designed specifically to detect the presence of various objects. It belongs to a group of photoelectric devices known as photointerrupters or slot type optoelectronic sensors and provides a digital output when a beam is interrupted. The OPB375T55 is an ideal solution for applications that require reliable and repeatable sensing of nearly any type of object ranging from small metal objects to thick paper stock.

The OPB375T55 utilizes light emitting diode (LED) source for emitting near infrared light which is then focused using an asymmetrical prism that is designed for thorough and reliable digital pulsing (dp) output. It has a molded plastic body for protection from the environment. Internally, a photo transistor receives the emitted light and by means of a latch circuit, produces a digital pulse when the light beam passes through an interruption of a certain size.

To ensure the reliability of the OPB375T55 it features an automatic circuit shutoff when no light is detected. This prevents false signals due to external interference and extreme lighting conditions. The OPB375T55 has an adjustable setpoint potentiometer which enables the user to adjust the level of interruption needed for detecting an object.

The OPB375T55 is perfect for applications in industrial automation and robotics, for example it can be used to detect part presence, object size and speed. Moreover it can be used for machine counting of various objects as well. With its adjustable setpoint via potentiometer, the OPB375T55 offers a very high degree of versatility suitable for a broad range of applications.

In summary, the OPB375T55 is an advanced slot type photointerrupter which is easy to install and provides reliable detection and output from small targets. It is excellent for applications with rapid detection of small objects. It features an adjustable sensitivity which makes it ideal for machine counting and speed detection.
