Optical sensors are one of the most popular types of sensors used in industrial automation due to their wide range of applications and relatively low cost. The E3Z-T81K 5M is one such type of optical sensor that is designed for industrial use. This article will discuss the application field and working principle of the E3Z-T81K 5M.

The E3Z-T81K 5M is a photoelectric, industrial optical sensor. It can detect objects or measures distances irrespective of their size, shape, or color. This type of optical sensor is used for shaft positioning, auto measurement of object sizes, parts counting, and presence/absence detection. It can also be used for detecting liquids, pressed components, and assembly defects. The sensor can be used in a variety of temperatures making it ideal for a range of industrial processes.

The E3Z-T81K 5M utilizes an IR LED light emission with high angles. It has a beam spot diameter of 0.6 mm, with the response time being 0.25 milliseconds at minimum, and 150 milliseconds at maximum. The LED wavelength is 950nm and the indicator emission type is Red. There are three optical axis types offered depending on the application needs – slot type (right angle to each other), cross type (angled type), and cylindrical type (conduit type). The sensor also offers a variety of sensing distances, with the minimum being 8 mm and the maximum being 80 cm.

The E3Z-T81K 5M works on the principle of retroreflective photoelectric sensing mode. It consists of an emitter and receiver which are mounted opposite to each other. When an object enters their path, the detection is triggered because of the light being reflected back from the retroreflector to the receiver. The time delay for each output will be shorter if the target is closer to the sensor. The output is soldered directly to the PLC or programmed with the appropriate software.

The sensing range of the E3Z-T81K 5M varies from 0.3 – 8mm, depending on the size and material of the object. It also has adjustable sensing range settings, allowing for fine adjustment of the sensitivity. The sensor also features an insulation resistant up to 5000VAC between voltage and all other parts. It has an intense brightness built-in LED indicator that is visible from all sides to show the presence of a target. It has a high EMC resistance and is designed to guard against dust and dirt.

The E3Z-T81K 5M is a robust and versatile optical sensor designed for industrial applications. Its wide range of features makes it an ideal choice for applications involving parts counting, presence/absence detection, and more. Its ability to be used in a variety of temperature ranges makes it an excellent choice for a wide variety of industrial automation processes.
