Optical sensors are versatile tools used to discern both the presence and absence of a variety of targets in industrial settings. Of the various types of optical sensors, photoelectric sensors, industrial sensors, and near-infrared sensors are the most commonly used. Each of these are applied in different ways, depending on their purpose or design, but all generally rely on the transmission and reception of light energy and the effects of light on the detector. Here we look at the PH18CNB20NAT1SA model optical sensor, which is in the family of near-infrared sensors, and its application field and working principle.

The PH18CNB20NAT1SA is a near-infrared distance sensor with a photoresistor made from a single light-emitting diode (LED). The sensor features adjustable switching distances that range from 0 to 15 cm, and is capable of detecting objects from a variety of distances. Applications of this sensor include proximity sensing, object detection, and environmental and position tracking. It is perfect for applications which require a close range, such as for a robotic arm or a security system.

The working principle of the PH18CNB20NAT1SA is based on the principle of near-infrared optics. When illuminated with a photon of near-infrared light, the light is reflected off the object at different angles. The sensor uses this variation in angle to calculate the object\'s distance from the sensor. The sensor then sends this data to an output device, which then shows the distance on the display. Additionally, the sensor can determine the size of the object by measuring the intensity of the reflection.

The PH18CNB20NAT1SA is a versatile and reliable sensor offering a variety of functions and features. It is designed for use in a range of applications such as hand-held devices, medical monitoring systems, security systems, and robotics. With its adjustable switch distances and its ability to detect a variety of distant objects, the PH18CNB20NAT1SA is perfect for applications that require short-range precision.
