Optical sensors are a type of sensing and control technology used to capture light signals and detect the presence or absence of objects. Photointerrupters are a subcategory of these sensors that utilize photoelectric sensing principles to detect the presence of objects that interrupt a light source. UFN3-70P415 slot-type optical sensors are transistor-output photointerrupters, one of the most commonly used types of photointerrupters, placing them among the better solutions for presence or absence sensing and detection.

UFN3-70P415 photointerrupters are part of Omron’s Micro Switch series of crescent-shaped sensors which feature a 3mm clearance width. The 3.6mm width, normal state distance, and space-saving design make them suitable for high density mounting assemblies, making them a good choice for applications which require greater accuracy and precision.

The UFN3-70P415 slot-type photointerrupters are equipped with a pair of vertical slot-type photoelectric sensors. The illuminating element emits NIR visible light detected by its phototransistor element. This pair of elements are integrated into a sealed, compact case enclosing an epoxy resin solid protective material to protect against dust and foreign substances. The circuit board containing the light source and phototransistor elements creates an optimal sensing area to enable effective, consistent detection and enhance ambient light immunity.

UFN3-70P415 slot-type photointerrupters are built with a maximum response frequency of 50 kHz in a wide supply voltage range, allowing easy adjustment according to the application. The high supply voltage allows the device to be used in a wide variety of applications, including machine interface, factory automation, and control circuits. The pair of optical phototransistors are typically used for industrial-level presence or absence sensing and control of objects.

The UFN3-70P415 slot-type photointerrupters are designed and assembled with an LED emission-type light source and a detection phototransistor to detect and control object motion. This assembly is designed to allow different types of physical objects, such as metal slotted disks, to be passed in front of the photoelectric sensor. When objects are sensed, the LED is on, and the phototransistor is off. When the object is absent, the LED is off, and the phototransistor is on.

The UFN3-70P415 photointerrupters feature a low operating current of 0.04mA, a NIR radiation wavelength of 830nm, and a maximum operating frequency of 50kHz. The combination of this active optical device and its integrated circuit makes advanced detection more precise and reliable, allowing for accurate and repeatable object detection.

The UFN3-70P415 slot-type photointerrupters are an excellent choice for industrial-level detection accuracy and control of objects. The integration of a robust LED emission-type light source and a detection phototransistor enables a more precise sensing of motion, allowing for more dependable operation. This particular sensor assembly features a small size for high-density mounting, a low operating current, and a wide supply voltage, allowing for greater versatility for a variety of applications.
