Optical Sensors - Photointerrupters - Slot Type - Transistor Output

Optical sensors are essential components in many types of automated systems. They provide quick and accurate sensing of object presence, speed, or size. Photointerrupters are one type of optical sensor that uses a the principle of an interruption of light to detect the presence of an object. The HOA1885-012 slot type photointerrupter is a transistor output device and is suitable for applications such as motor speed, question sorting, and document identification. This article will discuss the features and benefits of the HOA1885-012, its application field and working principles, and how it measures objects. The HOA1885-012 is a slot type photointerrupter specifically designed for applications with a limited space but with high accuracy and reliability demands. This device uses a gap-sensed design with an internal semiconductor sensor to detect objects with a resolution as small as .7mm. The device has an internal LED light source combined with an IR filter and a second filter to reduce false triggering from ambient light. This offer protection against crosstalk from other photointerrupters within the system. The device also offers excellent EMI resistance, with its pin layout optimized for compact circuit boards, allowing it to fit into a size as small as 0.2” x 0.08”.The HOA1885-012 is a slot type photointerrupter that uses a transistor output to detect the presence of an object. It works when an LED light source projects a beam of light through the gap between an object and the light receptor. When the object passes between the light source and the receptor, the light is interrupted is detected by a semiconductor sensor. This interruption triggers a logic switch in a transistor output circuit which is then read by the control unit.The HOA1885-012 provides reliable object detection and can be used to measure objects in multiple applications. It can be used to measure the speed of a motor, to differentiate between objects of different sizes and shapes, and to accurately identify and sort documents. It can also be used to count objects that pass through its sensing range, by counting the number of object interruptions within a certain amount of time or to detect changes in a signal or process.The HOA1885-012 offers a number of advantages over other optical sensors and is well suited for applications requiring accuracy, reliability and space-saving design. The device has an integrated LED and filter to reduce false triggering, and provides a good EMI protection. The gap-sensing design offers high resolution and its compact size makes it suitable for a range of applications with limited space.The HOA1885-012 is a reliable and accurate transistor output photointerrupter designed to detect the presence of an object. It is well suited for applications such as motor speed, object size and shape differentiation, document identification, and signal detection. Its compact size and integrated LED and filter make it perfect for applications with limited space, while its gap-sensing design offers high resolution and excellent EMI resistance.
