High-output design with ample margin! An electromagnetic actuator that flexibly accommodates all specifications.

The keep-type refers to a structure that incorporates a permanent magnet into a linear solenoid, and the "SKW series" is a bistable solenoid. The bistable type can hold the movable iron core at both ends of the stroke due to the force of the permanent magnet, and when current is applied to the coil on the opposite side of the holding side among the two attracting coils, it is attracted and held there. The monostable type holds only on one side but allows for freedom of movement in the stroke. 【Features】 ○ Energy-saving and space-saving ○ Comparable to mechanical locks ○ High output design with ample capacity ○ Flexible response to all specifications For more details, please contact us or download the catalog.

basic information

**Features** ○ Power is supplied only during operation, and the position is maintained by the force of a permanent magnet after suction. → This results in minimal power consumption. ○ Low power consumption rate. → This allows for smaller coils, enabling large forces to be achieved with a small solenoid. ○ Does not require external locking mechanisms or springs. → This reduces the number of components and allows for a compact design. ○ Operation is maintained by a permanent magnet. → It will not be pushed back by external forces like a spring. → It maintains its position up to the limit of its holding force. → Switching of passages does not require a locking structure. → It can maintain this force semi-permanently, with no mechanical wear. ○ Capable of flowing large currents instantly and operating at high speeds. ○ High output and high response design that can handle up to 20 times the continuous rated voltage. ○ In addition to standard specifications, we implement the optimal combination of permanent magnets, coils, movable iron cores, and yokes according to various requests. → Specifications: holding force, suction force, operating voltage, environmental temperature, driving power, etc. ○ Low-cost semi-order system. ○ Also supports special specifications. ○ Operates at high temperatures above 150°C and in a vacuum. → From the micro realm of semiconductors to the harsh environments of space. ● For more details, please contact us or download the catalog.
