ON Semiconductor OPB860N11 Optical Sensor

The OPB860N11 from ON Semiconductor is a versatile and high-performance slotted optical switch designed for a wide range of applications that require precise detection of object presence or motion. This optical sensor is part of ON Semiconductor's extensive portfolio of sensors that cater to the needs of modern electronic systems.

The OPB860N11 optical switch consists of an infrared emitting diode and an NPN silicon phototransistor, mounted facing each other in a black thermoplastic housing with a slot between the emitter and detector. The housing ensures ambient light immunity, providing reliable operation even in environments with variable lighting conditions. The slot width is designed to accommodate the passage of an opaque object, which interrupts the light beam and triggers the phototransistor.

This optical sensor is characterized by its compact design, which allows for easy integration into a variety of systems without requiring significant space. The OPB860N11 operates over a wide voltage range, typically from 3.0V to 24V, making it compatible with both low and high voltage circuits. Additionally, its output can be easily interfaced with a variety of digital circuits, microcontrollers, and logic systems.

Key features of the OPB860N11 include:

• Highly sensitive phototransistor output
• Wide operating voltage range for flexible design integration
• Compact and robust thermoplastic housing for durability
• Ambient light immunity for consistent performance
• Easy interfacing with digital systems

Applications for the OPB860N11 are diverse, ranging from industrial automation, where it can be used for limit switching and object detection, to consumer electronics, where it might be found in printers and copiers for paper jam or paper path detection. Its reliable operation and ease of use also make it suitable for safety interlocks, end-of-travel detection in mechanical systems, and various other sensing solutions that require a non-contact method of detection.

With its combination of performance, reliability, and versatility, the OPB860N11 optical sensor from ON Semiconductor is an excellent choice for designers and engineers looking to incorporate effective object detection and motion sensing capabilities into their projects.
