A bistable solenoid comprises a housing, a coil, a permanent magnet, an armature, a pin, and a spring. The coil is arranged inside the housing. The armature is slidably arranged inside the housing and can move between the first armature position and the second armature position. The pin extends at least partially out of the housing and is slidably fitted by the armature. The spring is biased between the armature and the pin. When the pin encounters an intermediate position between the retracted position and the extended position due to the pin fitting obstacle, the spring is configured to maintain a bias force on the pin until the obstacle is removed.

The bistable rotary solenoid uses a cylindrical permanent magnet as the axis of rotation and utilizes the repulsion and attraction between the permanent magnet on the axis and the magnetic poles on the yoke to form a rotational motion. After cutting off the power, the stable state will be maintained by the permanent magnet of the rotating shaft. Unlike traditional rotary solenoids that convert general mechanical linear motion into rotational motion through mechanical construction, this product directly generates rotational motion, thus eliminating the need for axial motion. This construction effectively extends the product's service life.
1. bistable type
By changing the direction of power supply, left/right rotation can be achieved; If there is no power, the position will be locked and maintained through a permanent magnet.
2. High output and fast response speed
By continuously switching the direction of power supply to achieve reciprocating motion without the need for springs, this product can have high output and fast response speed.
3. Spring reset type
The driving circuit of this product is simple and responds promptly
4. Can set action angles in a wide range
Within a range of 90 degrees, the angle can be set arbitrarily
5. No axial movement displacement can achieve low noise during operation
There is no axial movement displacement, and the angle limit pin is installed externally to reduce noise.
Some products have built-in limit pins, which use materials that have been tested to be low-noise and low vibration.
6 Long service life
Except for a ball bearing, no mechanical moving parts are used, which can give the product a longer lifespan.
7. Rich variety selection
Please choose the product according to your needs and usage.
