A 24V DC solenoid is an electromagnetic actuator that operates on a 24V DC supply, consisting of a coil and a ferrous metal plunger. It is simple and efficient, and requires proper power planning to avoid damage.
A 24V DC solenoid is an electromagnetic actuator specifically designed to operate on a 24V direct current (DC) supply. These devices are used to provide remote or automatic activation or switching motion to a secondary mechanism. They generally consist of a wire-wound static coil with a hollow core and a spring-loaded ferrous metal plunger. The plunger is usually positioned so that its end is just in or near the opening in the coil core. When the solenoid coil is energized with a current of 24 volts DC, the coil generates a strong magnetic force which pushes the plunger into the core, providing the necessary actuating motion.
The solenoid is one of the most common sources of remote or automated switching and triggering motion. Part of the great attraction of the solenoid as an actuator is its inherent simplicity of construction and operation. Most solenoids consist only of a coil of hollow flux-cored wire and a spring-loaded steel plunger or armature. When the coil is energized by an electric current, a powerful magnetic field is generated around it which pulls the plunger or armature towards the coil and activates the secondary device in the process. When power to the coil is cut off, the plunger spring pulls it out of the coil core and resets the solenoid.
The 24V DC solenoid is one such device that is designed to run on a specific power source, namely 24 volts DC. DC power supplies differ from conventional alternating current (AC) power plugged into a wall outlet in that they do not have the characteristic AC reverse polarity cycle. DC power is usually available from a battery or rectified AC source. This means that some power planning is required when installing a 24V DC solenoid to ensure that adequate power is available.
Electromagnetic actuators such as the 24V DC solenoid tend to be a bit simpler than those designed for AC or dual power. This is due to the fact that they do not suffer from the “chatter” of their AC brethren due to the 60 cycle polarity reversal. This eliminates the need for shading rings, making the DC solenoid less complex, quieter, and more efficient. When installing a 24V DC solenoid, always take care to use the correct power class and voltage. Incorrect power supply can lead to overheating with the risk of damage or destruction of the solenoid.
