GH-CX25/Magnetic Proximity Switch 220V with Magnetized Contact Features: No need for standby power supply, good airtightness, long service life, multiple magnetic field sensitivity ranges, can be matched with magnetic triggers. Customers can customize the color of the shell, outlet direction, wire, terminals, and other switch contact selection: In general industrial places, eddy current and capacitive proximity switches are usually used. Because these two types of proximity switches have lower environmental requirements. When the tested object is a conductive object or an object that can be fixed on a metal object, eddy current proximity switch J is generally chosen because of its high response frequency, good resistance to environmental interference, wide application range, and low price. If the measured object is non-metal (or metal), liquid level height, powder height, plastic, tobacco, etc. A capacitive proximity switch should be selected. This type of switch has a low response frequency but good stability. Environmental factors should be considered during installation. If the measured object is a magnetic material or if magnetic steel is buried inside the measured object to distinguish it from objects moving together, a Hall proximity switch should be used, as its price is low. In environments with good environmental conditions and no dust pollution, photoelectric proximity switches can be used. The photoelectric proximity switch has almost no impact on the measured object during operation. Therefore, it is widely used in both high demand fax machines and tobacco machinery., Automatic doors typically use pyroelectric proximity switches, ultrasonic proximity switches, and microwave proximity switches. Sometimes, in order to improve the reliability of recognition, the above-mentioned proximity switches are often used in combination. Regardless of the type of proximity switch selected, attention should be paid to the working 220V magnetic switch contact GH-CX25/The magnetic switch is a non-contact magnetic sensitive proximity switch, which is composed of a magnetic sensor, electronic circuit, and output switch. When the permanent magnet of the magnetic detection body enters the sensitive area of the magnetic sensor, the switch operates and outputs a switch signal under the action of the magnetic field. This signal reflects the position and direction of movement of the detection body, 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.
Magnetic switch contact GH-CX25 220V, abbreviated as magnetic switch, is composed of two parts: switch contact and magnet, used to detect the permanent magnet fixed on the tested object and perceive the proximity of the position. When the tested permanent magnet or object approaches the required opening distance (adjustable), the output switch signal or indicator light will light up. Due to the use of non-contact detection, it has high speed, long service life, and high reliability; The characteristic of stable operation in humid and corrosive environments or in flammable (explosive) environments. The explosion-proof magnetic proximity switch is composed of two parts: a magnet and a switch contact. Magnets are divided into two types: electromagnets and permanent magnets, and can be selected according to the needs of control. The switch contacts are divided into three forms: normally open contact, normally closed contact, and transfer control contact, which are also selected according to actual needs. The magnet and 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 direct current 24V power supply, and the two leads of the switch contacts should be connected in series to the power supply and load, and should not only be connected to the power supply, causing short circuiting and burning of the contacts. Main technical indicators: (1) Working voltage of the contact: DC 24V (our company has AC/DC 240V high voltage and high current products) (2) Working current of the contact: ≤ 0.4A (3) Control distance: ≤ 100mm (4) Sensing element size: × 20mm x 95mm (5) IP protection, etc.: IP68 (dustproof, waterproof, explosion-proof, shockproof, anti pull off, can work underwater). Note 1: Anti vibration - The sensor is encapsulated in epoxy resin inside, so it is not afraid of severe vibration. Note 2: Anti pull off - The use of waterproof joints at the outlet not only provides waterproofing, but also prevents the wire from being subjected to unexpected large pulling forces without damaging the internal chip. The GH-CX25 magnetic switch contact is made using electromagnetic working principle and technology, and is a position sensor. It can convert non electrical or electromagnetic quantities into desired electrical signals through changes in the position relationship between sensors and objects, thereby achieving the purpose of control or measurement. The detection distance that a magnetic proximity switch can achieve with a small switch volume. It can detect magnetic objects (usually permanent magnets) and then generate 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 magnetic conductors (such as iron). For example, signals can be transmitted to the magnetic proximity switch through high temperature areas to generate triggering action signals. The requirements for various indicators such as voltage, load current, response frequency, detection distance, etc. GH-CX25/Magnetic Proximity Switch 220V Magnetized Contact
