AC-laminated solenoid: This solenoid comprises a wire coil and a metal core made with laminated metal, which helps reduce stray currents and optimizes the solenoid’s performance. An AC-laminated solenoid has an inrush current, which delivers a greater amount of force in the initial stroke. This also means it can deliver more strokes than DC-laminated solenoids. Common applications of an AC-laminated solenoid include locks, medical devices, industrial equipment, vehicles, and other equipment that needs immediate operation.

DC C-frame solenoid: Some applications may also use a DC C-frame solenoid, which features a C-shaped frame that wraps around the wire coil. Suitable for many everyday applications ranging from gaming equipment and coin counters to scanners, camera shutters, and circuit breakers, this solenoid utilizes a stroke operation with excellent control. While it has a DC configuration, a solenoid of this type is actually AC power equipment compatible.

DC D-frame solenoid: Like C-frame solenoids, the DC D-frame solenoid operates with more controlled strokes and is compatible with AC power applications. The main difference is that the D-shaped frame is made with two joined pieces that shield the coil. ATMs, gaming machines, and gas- and blood-analyzing equipment often use this solenoid type.

Linear solenoid: This is one of the most widely recognized solenoids. A linear solenoid features a coil-wrapped metal core, delivering pushing or pulling force to operate a piece of equipment. This operation makes it popular for vehicle ignition systems and other such starting devices, as well as electric locks that allow locked vehicle doors to withstand significant force.

Rotary solenoid: If an application needs a simple automatic control process, it may use a rotary solenoid, which has the same essential components as other solenoids but with a unique mode of operation. A rotary solenoid uses a metal core located on a grooved disc to function. The size of the grooves is based on slots on the body of the rotary solenoid, and ball bearings facilitate and streamline motion. When it is powered on, the core draws back within the body while the disc core turns. When turned off, a spring forces the disc core into its original position. A more robust solenoid variety, the rotary solenoid has common applications in industrial tasks like automated lasers and shutters.

Latching solenoid: This solenoid type features a permanent magnet as well as a spring or related component to enable return force. Using just a brief excitation pulse, the latching solenoid will alter its end position. In the holding condition, it exhibits zero power or heat dissipation, so it is a good choice for temperature-sensitive applications. It is also compatible with systems that have minimal supply power because, at either end position, there is no power consumption. A latching solenoid is not, however, a good option for failsafe applications should a power failure occur.

Proportional solenoid: A type of advanced linear actuator, a proportional solenoid generates force that is proportionate to the amount of excitation current an application applies. This solenoid can, when a return spring is included in its construction, serve as a positioning device. Generally, it is utilized for position, flow control, tension, and force, and the proportional solenoid has common applications in hydraulic control systems, robotic systems, textile systems, and valves.
