Chapter 1: What is a Tubular Solenoid?
Tubular solenoids are miniature electromagnetic actuators which convert electrical energy into accurate linear motion. Tubular solenoid consists of a cylindrical body, copper coil, iron core and a moving plunger. Upon excitation they generate magnetic field, which results in the plunger moving and producing push or pull force. Due to their compact design, high force output, quick response and reliability tubular solenoids can operate in limited space.
Chapter 2: How does a tubular solenoid work?
Tubular solenoid operates on the basis of electromagnetic actuation principle which means the conversion of electrical energy into controlled linear motion. Tubular solenoids have a cylindrical iron core around which a copper coil is wound. Passing electricity through the coil generates magnetic field. The magnetic field is amplified by high permeability of the iron core. Due to efficient design tubular solenoids are capable of producing strong force with a compact structure.
A magnetic field acts on a plunger which is able to move within the tube. The excited plunger is moved inwards or outwards depending on the design of tubular solenoids. Such linear motion is utilized for mechanical operations like locking, switching or valve operating.
The force produced by tubular solenoids is directly proportional to the supplied current and the number of turns of the coil. This allows the precise control of motion making tubular solenoids ideal for automation, automotive and industrial control applications requiring rapid and reliable operation.
