Electromagnetic Locks Features

Electromagnetic Locks Features Electromagnetic locks are designed to take advantage of the physics behind electromagnetism. An electromagnetic lock comprises two main parts, an armature plate made of metal and steel plate surrounded by a coil of wire which can be magnetized. When an electrical current passes though the coil, the steel plate becomes magnetized and [...]

Electromagnetic Lock

Electromagnetic Lock An electromagnetic lock, magnetic lock, or maglock is a locking device that consists of an electromagnet and an armature plate. There are two main types of electric locking devices. Locking devices can be either "fail safe" or "fail secure". A fail-secure locking device remains locked when power is lost. Fail-safe locking devices are [...]

How does an electromagnetic lock work?

How does an electromagnetic lock work? electromagnetic lock work - An electromagnetic lock creates a magnetic field when energized, causing an electromagnet and armature plate to become attracted to each other strongly enough to keep a door from opening, according to HangSeng Magnetech Inc. most cases, the armature plate is on the edge of the door, [...]

Electromagnetic Chuck for Grinding

Electromagnetic Chuck for Grinding, Electromagnetic Chuck for Surface Grinding, Electromagnetic system Electromagnetic Chuck for Grinding - The coil system in the ElectroMagnetic chuck is designed to spread the heat optimally on the whole surface of the chuck. This is important for the machining of small and thin steel components for which these chucks are designed. Electrofine can [...]

Electropermanent systems by HSMAG

Electropermanent systems, electro-permanent magnetic system, electropermanent magnetic chucks Electropermanent systems by HSMAG - Electropermanent clamping systems are the combination of permanent and electromagnetic technology. They exploit the ability of some ferromagnetic materials to become a permanent magnet due to the fast action of strong direct current. In this state, they continue to function without the need of [...]

Permanent Magnetic System by HSMAG

Permanent magnets, Permanent Magnetic System, permanent magnetic chucks, permanent clamping system by HSMAG Permanent Magnetic System - In permanent magnetic chucks, we find the utilization of highly magnetized materials which in a particular arrangement facilitate the clamping of magnetic steel. Under normal conditions, they do not lose their magnetic force. permanent magnetic system chuck Activation [...]

How to Select Sensor Magnet Guide?

SENSOR MAGNET SELECTION Magnetic field profiles example Magnets, electromagnets and solenoids could all be used to trigger magnetic sensors such as Reed Switches and Hall Effect devices. The choice of magnet is determined by the actual application and the environment of the application. Temperature, distance and location of the magnet, presence of other [...]

HSMAG is a sensor magnet supplier. HangSeng Magnetech designs, produces and supplies magnets and magnetic assembly solutions for the Sensors Industry. Magnets for Sensor We can design magnets to provide specific field strengths at a required position relative to the magnet. We can design magnets to trigger Hall Effect devices at different locations compared [...]

How is Magnet Strength Measured?

A magnet is any object that produces its own magnetic field. The magnet strength of these objects can vary from imperceptibly weak fields to incredibly strong fields, depending on a number of characteristics. Magnets can be classed into two distinct groups: permanent magnets and electromagnets, and non-magnets can be defined as either ferromagnetic, paramagnetic, or [...]

What is a Superconducting Magnet?

A superconducting magnet is an electromagnet where the coils are made of a type II superconductor. It can easily create steady magnetic fields of 100,000 Oersted (8,000,000 amperes per meter). They produce stronger magnetic fields than standard iron-core electromagnets and cost less to operate. Superconductor electromagnets produce a significantly stronger magnetic field than iron-core [...]

What are Some Uses for Industrial Magnets?

Industrial magnets come in a wide range of types, shapes, sizes and strengths. They are utilized across a diverse spectrum of industries for an equally diverse set of purposes. Particular uses of industrial magnets depend upon particular requirements. Industrial magnets for dockside-derrick-crane The Magnetic Materials Producers Association (MMPA) and the Magnetic Distributors and [...]

Electromagnets vs Permanent Magnets

Permanent Magnets vs Electromagnets Electromagnets and Permanent Magnets: What are the Differences? An electromagnet is made from a coil of wire which acts as a magnet when an electric current passes through it. Often an electromagnet is wrapped around a core of ferromagnetic material like steel, which enhances the magnetic field produced by [...]

Permanent Magnet Strength

There are two primary types of magnets: electromagnets and permanent magnets. Electromagnets are essentially magnets that have an on and off switch. They have magnet power in the presence of an electrical current and lose their power when this current stops. Permanent Magnet Strength As you may have inferred by their name, permanent [...]
