Optical Sensors, specifically Photointerrupters, are transducer devices that convert optical radiation to electrical signals. Transistor Output Slot Type Photointerrupters are used to monitor the passage or interruption of light in order to sense the presence of a target in a solution or process. The HOA0870-N51 series of Photointerrupters are capable of responding to a wide range of applications and solutions and are a valuable tool for numerous industry applications.

HOA0870-N51 Photointerrupters are a combination of a phototransistor detector and an infrared emitting source package into a single sensor. The phototransistor detector and emitter are mounted at right angles in a plastic package, forming an adjustable, high-sensitivity slot-shaped sensor. The phototransistor has a built-in shield to ensure consistent sensitivity in both dark and bright environments, making it an ideal sensor for detection applications that are subject to significant fluctuations in lighting intensity.

The integrated design of the HOA0870-N51 Photointerrupters makes them ideal for applications where low profile packages are necessary such as SMD equipment, automotive applications, or other compact systems. Their operating principle is based on infrared radiation emitted from an LED source and received in a phototransistor detector. When a target passes through the slot of the sensor, the infrared beam is cut off, triggering the phototransistor to detect the interruption. The signal is amplified and transmitted as a transistor output.

The HOA0870-N51 Photointerrupters can be utilized in many industrial applications and processes such as paper/textile processing, material conveying, position sensors, motor homing and control, and encroacher detection. They can be used to detect the presence or absence of an object or feature and to monitor a process for positional accuracy and reliability. Their small form factor, low power operation, and wide operating temperature range make them an ideal choice for applications that require precise and reliable detection.

The HOA0870-N51 Photointerrupter features a low operating power, wide detection range, and adjustable detection area. Its adjustable design allows for its detection area to be tailored to the size and shape of an application’s target, increasing the accuracy and reliability of detection. It has a built-in shield to ensure consistent sensitivity in both dark and bright environments, making it an ideal sensor for detection applications that are subject to significant fluctuations in lighting intensity. Additionally, its low power consumption makes it ideal for battery-powered applications.

In conclusion, the HOA0870-N51 series of Photointerrupters are an ideal choice for applications that require precise and reliable detection. Its low power consumption, wide range of detection, adjustable detection area design, and ability to operate in fluctuating lighting environments make it a valuable tool for numerous industrial applications. From paper/textile processing to motor homing and control, the HOA0870-N51 Photointerrupter can help to ensure accuracy and reliability in a wide range of applications.
