Magnet-Schultz of America (MSA) is a leading manufacturer of standard and totally customized Solenoids, Electromagnetic and Electromechanical devices. Our advanced engineering, innovative design and advanced manufacturing capabilities provide our customers with uniquely tailored products and custom solutions that simply outperform the competition.
MSA offers many different reference designs involving C-Frame, D-Frame and Tubular Solenoids. All of our reference designs can be readily tailored to meet the requirements of any application.
Explore the dimensional and performance characteristics of all our Standard Solenoids reference designs to help refine your product selection.
C-Frame Solenoids are the most straightforward solenoid design. They provide the greatest economic value while operating at the most basic magnetic performance level.
D-Frame Solenoids offer moderate design complexity and price points. The box-style construction provides mid-range magnetic efficiency and performance.
Tubular Solenoids are the most complex of MSA’s three solenoid reference design categories. Tubular solenoids are also the most magnetically efficient and provide higher performance in smaller package sizes.
Specialty Solenoids (DURO-TECH, Magnetic Latching, Voice Coils)
MSA is driven to satisfy unique customer challenges. We embrace the opportunity to design and manufacture solenoids that address the needs of difficult applications.
This MSA trademarked family of highly versatile and durable electromechanical solenoids is designed and certified for use in extreme environments. DURO-TECH is available in two variants:
- Push or Pull—three sizes providing actuation in one direction
- Push-Pull—currently one size with bi-directional actuation
Their rugged tubular design, encapsulated coil, integrated connector and neoprene boots keep dirt and contaminants out, and offer excellent resistance to shock and vibration. A “hybrid” in the sense that it combines the many advantages of the coils from our Electrohydraulic product group (which are up to IP69 dust and water ingression rated), DURO-TECH solenoids are equipped with a highly specialized and rugged electromechanical operating mechanism and special rubber boots—providing an IP65 rated dust and water ingression capability.
MSA’s collaborative innovation approach to product design is perfectly suited to develop customized derivatives/variants of the DURO-TECH family to precisely meet your system’s requirements.
MSA offerings include semi- or fully-custom Magnetic Latches, Magnetic Latching Solenoids and Permanent-Magnet Electromagnets. All three products have permanent magnets embedded in the design.
These products provide a bi-stable device that requires “zero power” to remain in the magnetically-latched position. The permanent magnet decreases input power and “on” time requirements, and provides the hold force needed to remain in one state of actuation. A return spring typically keeps the device in the opposite state. Additional benefits include:
• Reduced Power Consumption—a magnetic-latching actuator can indefinitely stay in the actuated position, without the constant application of electrical energy that would be required for a regular Solenoid
• Lower Heat—the device is actuated and/or un-actuated with only a brief pulse of energy
• Battery Friendly—the minimal power requirements of Magnetic Latches make them ideal for use with the limited output and life expectancy of a battery power source
Typical applications for Magnetic Latching Devices include door-locking mechanisms, computer cabinet locks, electronic circuit breakers, fire-extinguishing system actuators, medical equipment and power line trip mechanisms.
To explore the design possibilities of Magnetic Latching Solenoids, contact us for a consultation with a Magnet-Schultz application expert.
Based on a technology similar to audio speakers, these custom actuators blend the power of Permanent Magnets with the intermittent actuation of Electromagnets in order to achieve high-speed functionality.
All MSA Voice Coil designs provide:
• Unique bi-directional force, velocity and acceleration characteristics
• Compact size, relative to other linear actuator technologies
• Custom bearing systems, enabling greatly extended life
• Suspended armature designs eliminating friction and providing long life
Fully custom Voice Coils—high-speed devices that are specifically designed to meet customer needs for precise linear movement, fast actuation and long life. Voice Coils are available in two basic configurations:
• Moving Armature Design—no moving leads, eliminating lead wear concerns
• Moving Coil Design—faster response time and high acceleration
MSA also has the ability to design and integrate Voice Coil technology into complete assemblies for customer applications which may significantly reduce your current assembly time and overall system cost.
Typical applications for these highly customized new products include medical respirators, pressure regulators, instrumentation controls and coin sorting.
Typical applications involve fire-door release mechanisms, MRI and X-ray bed locking mechanisms, building security, brake/clutch assemblies and other lifting or locking mechanisms.
MSA has eight (8) different sizes of Electromagnet reference designs, ranging from 20mm to 100 mm in diameter—providing from 16 to 833 pounds of hold force. We invite you to contact us to discuss your application.
Our goal is to provide the right solution for you. Please review the following Electromagnet reference designs to learn more about our unparalleled engineering services and begin a collaborative process that is right for your application.
Power Control Modules for Electromagnetic Actuators
In such scenarios, simply over driving the electromagnetic device is not a viable solution because it will cause overheating of the device, which will then deride performance, and even cause premature failure. There is a way to achieve higher forces from a given size of an electromagnetic device (possibly even move to a smaller device), while avoiding concerns relative to excessive heat build-up.
The solution is to power the device with Magnet-Schultz of America’s electronic Power Control Modules, which employ a Pulse Width Modulation (PWM) electronic driving scheme.

MSA can design and manufacture a range of Value-Added Assemblies, from simple to complex, incorporating the electromagnetic functionality needed to precisely meet your unique system requirements.
Three different levels of complexity have been defined, resulting in a Value-Added Assembly. As a fully tested “component”, the customer can easily place this assembly into an end-product without the hassle of procuring, assembling and testing all of the sub-components.
The base-level version of a Value-Added Assembly involves adding various mechanical features (brackets, connectors, spring-return mechanisms, etc.) to an MSA reference design product. The resulting customized product provides an affordable solution that can be installed directly into the customer’s system without additional assembly effort.
The mid-level Value-Added Assembly involves attaching an MSA product to a more complex mechanical sub-assembly. The design of the mechanical sub-assembly can either be provided by the customer or developed with assistance from our engineering team.
All of the required components are procured by MSA, and the resulting final product is assembled, tested and provided to our customer as a complete Value-Added Assembly—ready for installation into the customer’s system, without significant additional assembly effort.
The most sophisticated level of Value-Added Assembly involves a completely unique MSA design, incorporating the mechanical and electromagnetic features necessary to meet the magnetic actuation and all other functional demands within in the customer’s end product.
Because the structure of this assembly becomes the magnetic envelope, it eliminates the need and cost for a separate electromagnetic device.
The result is a more cost-effective, higher-performance component—eliminating additional assembly and customer testing efforts, while adding value to the end product.
