Open-Frame Series

Johnson Electric's linear open-frame solenoid technology consists of an open iron frame, an over-molded or taped coil, and a movable plunger in the center of the coil. This platform is available in AC and DC versions and in two frame styles: the C frame style, in which the coil is enclosed on one side, and the box frame style in which the coil is enclosed on two sides. The box frame style provides slightly higher force output and higher resistance to environmental conditions.

Open-frame solenoid technology offers an economical design for high-volume applications, continuous or intermittent duty, and on/off operation. This technology offers life up to 5 million cycles and a variety of size, force, and stroke options. Open-frame solenoids are the most economical of all the solenoid types and are typically selected for applications in which extremely long life and precise positioning are not critical. For low-duty cycle applications, consider a magnetic latching open frame.
