Linear solenoids are electromechanical devices that generate a uniform magnetic field when an electric current is applied to them. They are composed of a coil of wire wrapped around a moveable metal core.
When electricity passes through the wire, a magnetic field is created which moves the mobile metal slug along the length of the solenoid's core, exerting a simple pushing or pulling force, as opposed to a rotational force found in rotary solenoids.
Linear solenoid actuators offer exceptional precision, reliability, and come in versatile voltage options, including 12V and 24V configurations, designed to suit various industrial and control systems. Engineered for long-term, reliable, and durable performance, they excel in heavy-duty and high-cycle applications.
Linear solenoids are critical components in automation, valve control, and other demanding applications requiring precise push or pull forces.
Linear solenoids and actuators come in various designs, each tailored for specific applications.
Electric solenoid actuators are the most common type, converting electrical energy directly into linear mechanical motion. These are ideal for applications requiring automated, electrically controlled linear actuation in systems like locking mechanisms, circuit breakers, and industrial machinery.
Although "solenoid" typically refers to an electrically actuated device, the term "mechanical solenoid" is sometimes used to describe the mechanical components or output of a solenoid-driven system.
It generally refers to actuators that produce linear motion through mechanical means, often triggered by an external signal—usually electrical.
These mechanisms are commonly integrated into systems like interlocks, latches, or lever assemblies where a solenoid’s movement initiates a mechanical action.
Push-pull solenoid actuators are versatile linear solenoids designed to provide force in both extension and retraction. Their key function is to offer bidirectional linear movement.
They are ideal for applications requiring precise back-and-forth motion, such as in automated dispensing systems, medical devices, and can even include waterproof versions for demanding environments.
Heavy-duty solenoid actuators are linear solenoids engineered to withstand demanding industrial environments and deliver substantial force over extended periods.
Their primary function is to perform high-force push or pull tasks reliably and repeatedly. These solenoids come in voltages ranging from 12V to 230V, accommodating both DC and AC power sources to suit various application needs.
These are ideal for applications in heavy machinery, industrial brakes, large valve control, and any system requiring durable, high-cycle linear actuation.
Linear solenoid valves are electromechanically operated valves that use a linear solenoid to control the flow of fluids. The solenoid's push or pull motion acts as a plunger to open or close the valve.
These solenoid actuators are ideal for applications requiring precise and rapid control over fluid or gas flow in systems like pneumatic and hydraulic circuits, irrigation systems, and process control in manufacturing.
