The keep-type refers to a structure that incorporates a permanent magnet into a linear solenoid, and the "SK series" is a single-stable solenoid. The single-stable single-coil type holds the movable iron core with the force of the permanent magnet when not energized, releases the hold with reverse current, and attracts with forward current. However, the energization conditions differ between release and attraction. The single-stable double-coil type has a separate release coil, allowing for release and attraction under the same energization conditions. 【Features】 ○ Energy-saving and space-saving ○ Comparable to mechanical locks ○ Flexibly accommodates various specifications For more details, please contact us or download the catalog.
