Magnetic switch WK509K225 is a non-contact magnetic proximity switch composed of a magnetic sensor, electronic circuit, and output switch. When the permanent magnet of the magnetic detection object enters the sensitive area of the magnetic sensor, the switch is activated by the magnetic field, and the switch signal is output. This signal reflects the position and direction of motion of the detection object, and can be used as the travel position signal of the control system. By adopting fault-tolerant hot backup and high anti-interference technology, high technical indicators and performance have been achieved, making it suitable for mines with relatively fixed lifting containers. The protection level is above IP67, explosion-proof, waterproof, and anti smashing, and it can work safely and reliably in the mine shaft without maintenance. It can be used in conjunction with various automatic electrical control equipment to provide corresponding acceleration, deceleration, and positioning signals for mining electrical control equipment. Thus effectively improving the automation and positioning accuracy of electronic control.

It adopts the principle of magnetic induction. It has the characteristics of collision free and strong force. Mainly used for detecting the position of moving objects, when the magnetic steel on the moving object passes through, the proximity switch output contact closes, and when it leaves, the contact opens. It is applied in places with explosive hazards such as coal mines, chemicals, and petroleum, and is an ideal sensor in modern automatic control systems.

Overview

The explosion-proof magnetic switch WK509K225 is of intrinsic safety structure, with internal sealing and IP67 protection. The switch adopts the principle of magnetic induction, with no collision and strong force. It is applied in places with explosive hazards such as coal mines, chemicals, and petroleum, and is an ideal sensor in modern automatic control systems.

The mining proximity switch is mainly used for detecting the position of moving objects, and this switch belongs to the memory type proximity switch. When the magnet passes through the mining proximity switch from one direction, the output contact closes and remains, and when it passes through the proximity switch again from another direction, the output contact opens and remains. Product Description:

The explosion-proof magnetic proximity switch is composed of two parts: the magnet and the switch contact. Magnets are divided into two types: electromagnets and permanent magnets, and can be selected according to control needs. The switch contacts are divided into three forms: normally open contacts, normally closed contacts, and rotary control contacts, which are also selected according to actual needs. The magnet and the contact should be installed on the same axis, and the distance between the two should be within the working distance. There should be no strong magnetic field around the switch contacts to avoid any impact. Electromagnets require a 24V DC power supply, and the two leads of the switch contacts should be connected in series with the power supply and load. It is not allowed to short-circuit and burn out the contacts by only connecting to the power supply. Wiring should be as short as possible and kept as far away from other wiring as possible

2. Functional non memory magnetic proximity switch, non-contact, with on/off or switching functions to achieve alignment, limit and various control purposes.

Magnetic proximity switch is a type of proximity switch that utilizes electromagnetic working principles and is made using a process. It is a position sensor. It can convert non electric or electromagnetic quantities into desired electrical signals by changing the position relationship between sensors and objects, thereby achieving the purpose of control or measurement. The detection distance that magnetic proximity switches can achieve with a small switch volume. It can detect magnetic objects (usually magnets) and generate a trigger switch signal output. Due to the fact that magnetic fields can pass through many non-magnetic objects, this triggering process does not necessarily require the target object to be directly close to the sensing surface of the magnetic proximity switch. Instead, the magnetic field is transmitted to a long distance through a magnetic conductor (such as iron). For example, a signal can be transmitted to the magnetic proximity switch through a high-temperature location to generate a triggering action signal.
