Product Introduction
Takano Latching Solenoids are self-holding linear actuators that use magnetic force to hold position and move axially by electrical pulse. They are energy-efficient with low heat and come in bi-stable or mono-stable types.
- DC-powered pull-in; holds position with permanent magnet after coil is de-energized.
- Holds position with permanent magnets—no power or locking needed, avoiding coil heating.
- Cost efficient

Please choose a long model of 16 x 16 mm or a short model of 25 x 25 mm. Even with the same size of 25 x 25 mm, you can choose a stroke of 5 mm or 10 mm. Some silent models are also available. There are various variations, so please choose according to your purpose.
Structure and Operating Principles
Structure
- It is composed of two coils with a permanent magnet located between them. When not energized, the magnetic field of the permanent magnet is generated in the direction of the dotted line shown in the left figure, which enables the position to be held on both sides.
- Stays in the set position even during a power outage. No locking mechanism required. Moreover, free from problems such as coil temperature rise or heat generation because no holding current is required.
Operating Principles
When switch SW1 is turned on
When switch SW1 is turned on（with SW2 off）, the shaft is pulled from A to B. Even if switch SW1 is reset the shaft stays in position.
When switch SW2 is turned on
When switch SW2 is turned on（with SW1 off）, the switch is pulled from B to A.
In either case, in order to cancel out the holding power of the permanent magnet on both coils (not just on the holding side), it is necessary to insert an external resistor ( R ) for degaussing. Thus, the unit operates on a two-loop structure.
Thus, the unit operates on a two-loop structure.
