What is a rotary latching solenoid ?
A rotary latching solenoid is an electromechanical device that combines rotation and latching functions. It is mainly used to convert electrical energy into mechanical rotational motion and can maintain a specific position without consuming electricity. Here are the details:
Rotary Latching Solenoid 's Structure : it Usually composed of coil, permanent magnet, armature, and base. The coil generates a magnetic field when energized. The permanent magnet forms a magnetic flux flow path between the opposite pole faces of the armature and the base. The armature is the rotating part, connected to the output shaft or mechanism.
Working principle: When the solenoid is energized, the coil generates a magnetic field that interacts with the magnetic field of the permanent magnet. This causes the armature to rotate to a specific position. Due to the locking function, once the armature reaches the target position, it can be held in place by the magnetic force of the permanent magnet even if the power is removed. To change the position of the armature, it is necessary to apply an appropriate electrical signal again to overcome the locking force and drive the armature to rotate to another position.
Technical Parameters
Power supply voltage: usually 12V, 24V DC, etc. Different models have different voltage requirements.
Rotation angle: Common rotation angles include 30°, 45°, 90°, etc. The specific angle depends on the design and application requirements of the project.
Duty cycle: Indicates the proportion of power-on time in a duty cycle to the total time, which can be 10%, 15%, 100%, etc.
Power consumption: The power consumed by the solenoid valve when it is energized, ranging from a few watts to tens of watts depending on the model.
Switching time: Generally within tens of milliseconds, this is the time required for the electromagnet to complete one rotation and latching action.
advantage
Energy saving: It consumes power only when switching positions, and does not require continuous power supply to maintain the position, which can save energy.
High reliability: The self-locking function ensures that the position remains stable and is not easily affected by external factors.
Compact structure: Relatively small in size, can be installed in a small space.
