Optical sensors are a type of sensor technology that convert light rays, usually in the visible or infrared spectrum, into measurable electrical signals. The FT-42-30T is a particular type of optical sensor that is designed for industrial applications. This article will discuss its application field and working principle.

Overview

Model FT-42-30T is an inductive proximity optical sensor manufactured by TRS Sensors. It has a sensing range of up to 40 mm and its working frequency range is from 2 kHz to 2 MHz. The FT-42-30T is designed primarily for side-mounting and non-metallic detection and is available in several casing styles including cylindrical, rectangular, and square.

In terms of dimensions, the FT-42-30T is approximately 42 mm long and 30 mm wide and has a sensing range of up to 40 mm. It is designed to operate at temperatures ranging from -25°C to + 85°C (-13°F to +185°F). It is also RoHS compliant and CE marked.

Application Field

The FT-42-30T is designed for use in a wide range of industrial applications, such as positioning and material handling systems, packaging machinery, assembly lines, and robotic cells. It is also used in surface inspection, die casting, and machine vision applications. In addition, it is suitable for use in automotive, aerospace, and food and beverage industries.

The FT-42-30T is designed to provide reliable detection and sensing at high speeds and in harsh environments. It is capable of detecting objects that are submerged in liquids and can also be used in high-pressure washing and other types of harsh washing applications. Its rugged construction is designed to withstand vibration and harsh environmental conditions.

Working Principle

The FT-42-30T utilizes an inductive sensing technology, which means it uses an external magnetic field to sense the presence or absence of metallic objects. It works by emitting a low frequency magnetic field which is detected by a receiver circuit. If a metallic object enters the sensing area of the FT-42-30T, the magnetic field is altered. This alteration is detected by the receiver circuit, which then delivers output signals indicating the object\'s presence.

This sensing principle is based upon the Faraday shield effect, which states that a current carrying wire or loop placed in a magnetic field will induce an electric current, due to the Lorentz force. In the case of the FT-42-30T, the sensor emits a magnetic field which is detected by the receiver. When the magnetic field is distorted by the presence of a metallic object, the receiver detects a change in the received signal. This change is then used to indicate the object\'s presence.

Conclusion

In conclusion, the FT-42-30T is an optical sensor designed for industrial applications. It is capable of detecting objects in a range of industrial applications, including positioning and material handling systems, packaging machinery, assembly lines, and robotic cells. It utilizes an inductive sensing technology, which works by emitting a low frequency magnetic field which is detected by a receiver circuit. If a metallic object enters the sensing area of the FT-42-30T, the magnetic field is altered, which is then detect by the receiver circuit and used to indicate the object\'s presence.
