Proximity/occupancy sensors can detect the presence of objects without physical contact, and are widely used in all kinds of industrial automatic control systems.This article introduces the application field and working principle of LOIRWVRPQTI finished units.

Application field

LOIRWVRPQTI is a high-precision non-contact magnetic induction proximity/occupancy sensor. Its switching distance is up to 5mm, which is suitable for harsh conditions, such as dust, oil and water. It features high performance, quality and reliability, and is compliant with IP67 waterproof protection.

With its award-winning design and exceptional versatility, LOIRWVRPQTI finished units can be used in a wide range of applications. It is suitable for use on automatic doors, chain conveyors and machine tools. They can be used to detect the position of different objects, such as a cardboard box on a conveyor belt, the opening and closing of an automatic door, a falling object, or a metal object in a liquid. Its advantage is fast response, high reliability and stability in the harsh industrial environment.

Working principle

The LOIRWVRPQTI sensor consists of a sensing element and an electronic detection and signal processing circuit. The sensing element contains a winding, a permanent magnet and an iron core. When there is no object near the sensor, the permanent magnet produces an alternating magnetic field in the winding. The electronic detection circuit detects the signal of the magnetic field, and the signal processing circuit transforms it into a digital signal output.

When an object enters the sensing range of the sensor, the permanent magnet\'s alternating magnetic field will interact with the object\'s metallic field, and the amplitude of the signal in the winding will be increased. The electronic detection and signal processing circuit will judge that there is an object in the proximity, and process and output a digital signal. The service can be accurately completed in the millisecond range.

In addition, LOIRWVRPQTI has many functions, such as adjustable distance, varying sensitivity, hysteresis, temperature compensation, and electromagnetic interference protection. It can adapt to harsh industrial environment and meet various requirements for automation applications.

LOIRWVRPQTI finished units have great versatility and reliability, making them suitable for a variety of applications.The article above introduces their application field and working principle. Combined with their many excellent functions, LOIRWVRPQTI can meet the needs of different automation system environments.
