A Linear Solenoid is an electromagnetic device that converts electrical energy into a mechanical pushing or pulling force or motion. Deltrol Controls offers a wide variety of different linear solenoid models including C-frame, D-frame, Tubular MED, and Magnetic Latching. Solenoid models are capable of providing up to 1.5” of stroke or travel depending on the model. Different coil windings are designed to provide a range forces at different stroke lengths. Many models are UL recognized which assists customers in obtaining required agency certifications.

Johnson Electric’s SoftShift linear solenoids provide slow, smooth position control or high speed snap action operation. SoftShift solenoids have a unique construction which allows easy transition from snap action to variable positioning. Using the same power, starting force is three to five times higher than standard solenoids at the fully de-energized position. This is advantageous for starting inertial loads or detent mechanisms, and for conserving electrical power. This solenoid offers quiet operation, high power density, and a variety of sizes. Custom engineered solutions ensure that exact application requirements are met. With life of 10 million cycles, the SoftShift platform is ideal for applications requiring closed loop velocity and position control.

Laminated AC Linear Solenoids from Johnson Electric have a T-shaped laminated designed plunger and laminated steel frame. This platform has the unique ability to hold an exceptionally heavy load with quiet operation. To minimize the humming or chattering of most AC solenoids, the contact surfaces of the laminated frame and plunger are machined to provide a smooth and flush contact surface.
Our Super-T Laminates are products developed from years of engineering, research and manufacturing experience. Available in various frame sizes with life up to 100,000 cycles and a variety of plunger and coil arrangements, this platform is ideal for most very high force AC applications including industrial equipment, business machines home technologies and HVAC.
Johnson Electric’s Low Profile Linear DC Solenoids offer extremely compact design which optimizes the magnetic flux path for maximum force versus stroke characteristics. The construction of the plunger assembly provides an auxiliary flux path which permits a significant increase in force. The reliability and high performance of the low profile design make it an ideal choice for applications in which consistent, reliable operation is critical. Long life operation with a very high force in a small package make the Low Profile Linear DC Solenoid technology idea for a variety of applications including pumps, packaging equipment, and instrumentation & testing equipment.

- Automatic shut-off for fuel pumps
- Parking brake lock for material handling equipment
Johnson Electric’s linear open frame solenoid technology consists of an open iron frame, an overmolded 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 only on one side, and the Box Frame style in which the coil in 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 common in applications such as vending machines and automated door locks. This technology offers life up to 5 million cycles and a variety of size, force and stroke options. Custom designs can significantly increase life performance.
