OPB983P55

The OPB983P55 is an optical sensor of the photointerrupter slot type, used to detect the presence, absence or direction of a target or object. It is designed with a logic output which is typically used in user control systems or automation processes. The OPB983P55 is most commonly used in automated equipment, industrial robotics, electronic office equipment, printers, scanning devices, and factory automation.

The OPB983P55 is often chosen because of its self-contained, easy-to-install construction, and relatively low cost compared to other photointerrupter types. A critical component of the sensor is its infrared emitter/detector opto-coupler, also known as a modulated light source, which is part of the sensor\'s logic output.

The OPB983P55 consists of two distinct sections: an emitter section and a receiver. When the emitter and detector are of opposite binary logic states, the circuit will be open. When both are in a low state or equal logic state, the circuit will close. The ON and OFF states of the sensor will differ depending on the position or movement of an object near the two sections. The signal is produced when an object breaks the logic output circuit between the emitter and receiver.

The most common application for the OPB983P55 is sensing the presence or absence of a target, such as in material handling robots or automated conveyors. It is used to monitor mechanical equipment and detect the presence or absence of objects that the equipment is designed to manipulate. The sensor is also used for presence and absence detection in pick-and-place, or assembly line type operations.

The OPB983P55 also offers reliable protection against ambient disturbances such as dust, water spray, and high voltage spikes. This feature makes the sensor suitable for wet or dusty industrial environments, where a regular mechanical limit switch is not suited. The sensor can also detect and respond to changes in color, opacity, or reflectivity of an object passing through its field of view.

Due to its high immunity to EMI, RFI, transient voltage, ground loops, ion radiation, and other forms of interference, the OPB983P55 is very reliable in industrial applications. With its high signal immunity and a response rate of 4 microseconds, the sensor is suitable for fast-moving objects. The sensor can be easily integrated with other electronic systems, such as PLCs, computer-driven equipment, and power supplies.

Overall, the OPB983P55 represents a versatile and cost effective photointerrupter type, which is suitable for many applications that require reliable sensing of movement or presence. The device also offers excellent protection against external interference, making it ideal for use in harsh or hazardous environments.
