Latching solenoids come equipped with a permanent magnet, exhibiting magnetic attraction between the plunger and pole piece with no electrical power applied.


With a spring or other load providing return force, the latching solenoid requires only a momentary excitation pulse to change position conferring the following advantages on these devices:

• Power consumption is zero to hold in either end position – this is advantageous for systems with limited power supply such as battery powered devices, or devices powered by telephone line power, or solar power.

• Power dissipation (heat) is zero in the holding condition – this is advantageous to handling temperature-sensitive materials such as photochemicals, blood products, or chemical reagents.

• There is no radiated electrical noise in the holding condition (there is a fixed magnetic field due to permanent magnets), this can be advantageous in sensitive measuring circuits.

• The ability to hold end position without power, can allow higher ower to be applied during the excitation pulse for a given size of device without causing heating problems, this can allow higher operating speed to be realised, or allow a smaller device to be used to move the load in a given application.
