Energise-to-Hold Electromagnet

Overview - Energise-to-Hold Electromagnet

Standard Electromagnets (Energise-to-Hold Electromagnets/Electro-holding magnets)

Energise-to-Hold Electromagnets are standard electromagnets. It has a solenoid (copper wound coil), mounted within a high quality, highly permeabilised iron assembly to provide high clamping forces and low magnetic losses. The electromagnet energising unit is constructed with an iron cylinder with a nickel finish passivated with a body mount. A number of keeper plates (armature plates) are available to suit the holding of an electromagnet unit. The electromagnet's rear face has a central and three equi-spaced tapped holes (on a PCD).

ElectroMagnet with 3 Styles of Electrical Connection

Depending on the size, the Energise-to-Hold Electromagnet has three styles of electrical connection: free leads, two-pole connector and Hirschman connectors.

The Energise-to-Hold Electromagnet has, depending on the size, three supply voltages:- 12V dc, 24V dc and 240V ac. The electromagnet has an ED rating of 100% and an IP rating of 54 (20 for the two-pole connector version). They also have maximum possible pull force ratings from 113N up to 3500N (11kg to 350kg) depending on the size of unit (the actual pull achieved will depend on the application). High-quality permeable iron for low remanence.

Electrical current is required to turn the magnet ON. Power is removed to turn the magnet OFF. Pull force conversion (approximate): 1kg = 10N = 2.2lb. The outer shell of the electromagnet is a sturdy bright nickel plated cylinder, passivated with body mounting. Designed for surviving demanding holding and clamping applications.

Typical applications of the electromagnets include: door locking mechanisms for access control or security, fire door holding, medical devices , feeder systems for automated packaging machinery, pick and place equipment and power generation. Find out more about  Electromagnets & Electromagnetism.

Advantages of Energise-to-Hold Electromagnets

• The clamps only work when there is an electric current

• Changing the current can result in varying clamping force

• A high magnetic clamping forces possible

• An easy-to-use on/off switch operation
