Optical Sensors play an increasingly important role in automation and control systems. They are typically used to measure light intensity, photo-detectors and photo-emitters to detect motion, and encoders to measure distances. The HOA6961-N55 is a type of photointerrupter used as a Slot Type Logic Output, which typically offer an all-digital solution for a wide variety of applications. This article will discuss the application fields and working principles of the HOA6961-N55.

Application fields

The HOA6961-N55 optical sensor is a logic output device capable of detecting the presence of an object or material in a slot by opening and closing a switch. This means it is well suited for use in auto-feeders, where it can detect the presence of a discrete object, such as a screw, in the slot. This type of photointerrupter can also be used in paper thickness detectors, where it can detect the presence of a sheet of paper in a slot. Additionally, the HOA6961-N55 can be used in presence/absence detection, where it can detect the presence of an object in a slot.

The HOA6961-N55 is also ideal for use in safety applications, where it can detect the presence of a person in a certain area. It is well suited for use in machine/automation safety systems, where it can detect the presence of a person in a hazardous area. Additionally, this type of photointerrupter can be used in automated door systems, where it can detect the presence of a person near the door, allowing the door to open automatically.

The HOA6961-N55 can also be used in construction and agricultural equipment, where it can detect the presence of a worker in a certain area and enable the equipment to operate safely. Additionally, this type of photointerrupter can be used in assembly lines, where it can detect the presence of a part in a certain area and enable the assembly process to move forward.

Working principle

The HOA6961-N55 optical sensor works with infrared light. An infrared light source is used to emit an infrared beam through a slit or slot in the photointerrupter. This beam is then reflected off of an object or material in the slot and back into the HOA6961-N55. When the object or material is present, an internal mirror within the HOA6961-N55 reflects the infrared light and the switch opens and closes. When the object or material is absent, the switch remains open and output is high.

The maximum output load current of the HOA6961-N55 is 80mA, enabling it to be used in a variety of high-power applications. This type of photointerrupter offers high immunity to EMC, electrostatic and magnetic fields, making it suitable for use in industrial applications. The HOA6961-N55 also offers high accuracy and response time, with a response time of 12μs.

The HOA6961-N55 optical sensor is a powerful and versatile device, suitable for a wide variety of applications. It can be used in a variety of safety applications, as well as auto-feeders, paper thickness detectors, presence/absence detection, construction and agricultural equipment, and assembly lines. It offers an all-digital solution for easy implementation and has high accuracy and response time. This type of photointerrupter is an ideal choice for applications requiring high levels of detection accuracy.
