What is a safe solenoid

Basic knowledge of safe solenoids:
1. An electromagnet is an energized solenoid with a core. The magnetic size and current of the electromagnet depend on the number of turns of the solenoid.
2. The working principle of the magnet: The working principle of the electromagnet is to use the principle of electromagnetic induction, and the magnetic field is mainly designed and calculated using the Biot-Savart law and Kirchhoff's law.
3. The characteristics of electromagnets are: whether the electromagnet itself is magnetic or not, can be controlled by turning on and off the current, and the magnetic size can be changed.
4. The size of the current is controlled, and the direction of the magnetic pole is determined by the direction of the current.

Safe electromagnet selection main parameters
The following technical parameters need to be taken into consideration when the customer selects or customizes the required safe electromagnets:
1. Shape: The maximum size of the mounting electromagnet position: length; width; height,
2. The maximum stroke of the electromagnet and its suction requirements, the reset force requirements after power off
3. Maximum voltage supplied to the electromagnet; current and voltage stability; AC/DC power supply; positive or negative power;
4. Whether the electromagnet needs long-term uninterrupted work; intermittent work, the longest power-on time and the shortest interval between two power-on;
5. The use of electromagnets, special requirements for the use of electromagnets, such as temperature; humidity; impact; vibration; acceleration, etc.

Safe Electromagnetic Application Area
All kinds of small precision electromagnets and electromagnet application components, as the implementation of automatic control systems, have been widely used in industrial automation control, office automation, medical equipment and other fields. Such as office equipment, video equipment, banking equipment, packaging machinery, medical equipment, food machinery, textile machinery, automatic sorters, automatic teller machines, vending machines, card punches, electromagnetic locks, various remote control devices, brake devices , counting devices, access control systems, etc.
