JF-0530B Solenoid EN

Overview

The JF-0530B solenoid is a device that converts electrical signals into mechanical motion, using the principle of electromagnetic induction.

When current flows, the iron core moves forward due to the magnetic field, and when the current is cut off, the iron core returns to its original position by the spring.

Working Principle

It is composed of a coil that generates a magnetic field when current flows. When current passes through the coil, a magnetic field is formed, and the movable iron core inside moves accordingly. This process generates mechanical motion (linear motion), and when the power is turned off, the iron core automatically returns to its original position.

Specifications

Size	(Body) 30.1 x 13.2 mm / Including iron core approximately 61mm
Voltage	6V, 12V, etc. In this example, the 6V model is used.
Type	Push & Pull

Example Usage

It is difficult to supply the current required to operate the JF-0530B solenoid directly from the Arduino's digital pins.

To solve this, we use a Relay Module or MOSFET to safely control the current.

Be careful as the solenoid may heat up if operated for long periods of time with short intervals.

Difference Between Relay and MOSFET

MOSFETs consume less power during switching, and since they are electronically controlled switches, they operate much faster than relays.

Moreover, they do not have mechanical parts, which gives them a longer lifespan compared to relays that require physical movement.

However, relays can handle higher voltages or currents and are more suitable when electrical isolation is needed between the Arduino and devices.

Therefore, it is best to select and use them appropriately based on the situation.
