Takano Latching Solenoids are self-holding linear latching solenoids which maintain its position only with magnetic force and performs linear axial movement by electrical pulse. It's energy efficient with low heat generation.
There are either bi-stable type or mono-stable type based on the type of circuit.
Pulls in as the coil is energized. Stays in position using the magnetic force of the permanent magnet even after the coil is de-energized.2. Stays in position using the holding force of the permanent magnets
Stays in the current 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.3. Cost efficient
|Requires only energization for reciprocation and stays in position only by the holding force of the permanent magnets on both sides. Ideal for use as a drive or multi-contact switch for the flappers in banking terminals or for shutters for optical systems, in particular when high holding force is required.|
|Mono- stable||Standard type||
|The single side type which pulls in during the energization and stays in position using the holding force of the permanent magnets even after de-energization. This model is ideal for tube retainers for medical equipment or selectors in textile machines.|

With SW1 switched ON, it absorbs on to the primary coil side. It still keeps the position after the switch is reset.
With SW2 switched ON, it absorbs on to the secondary coil side. It still keeps the position after the switch is reset.
R is an external resistor. (holding side, for demagnetization current value setting)
Various circuits for driving a latching solenoid have been devised by customers. What follows shows one such example for reference:Operational mode
Pulls in from right to left at switch-on of SW1 and stays in position even after switch-off of SW1.
