Holding Solenoids
Holding solenoids generate a strong magnetic holding force when energized, providing secure positioning as long as power is applied. Unlike permanent magnet (latching) solenoids, the holding force disappears immediately when power is removed, enabling fast release and precise control.
Featuring high holding force, simple control, and reliable operation, holding solenoids are widely used for positioning, locking, lifting, and release mechanisms in industrial automation and medical equipment.
Typical applications include fire door release systems, MRI and X-ray table locking mechanisms, automated conveyor and sorting systems, clutch assemblies, and various lifting, positioning, and locking mechanisms.
Operating Precautions
- For optimum holding performance, the contact surface of the workpiece should be as flat and smooth as possible, and the contact area should not be smaller than the holding surface of the electromagnet.
- Holding force is defined as the magnetic force generated when the energized electromagnet is in full contact with a ferromagnetic object.
High-Standard Quality Control
100% Holding Force Inspection with Customized Test Fixtures
Holding solenoids are commonly used in elevator brakes, parking systems, and other safety-critical applications where consistent holding performance is essential. Holding force can be influenced by the flatness, surface finish, and plating thickness of the mating surfaces.
To ensure reliable performance, Magtek combines stringent material control with customized inspection fixtures developed for each manufacturing process and application. Every holding solenoid undergoes 100% in-line holding force testing, ensuring compliance with customer specifications for holding force and release current while maximizing product consistency and reliability.
Every application has unique requirements. Magtek provides customized Holding Solenoids based on the dimensional and technical specifications listed below, ensuring an optimal solution for each customer’s application.
