Open Frame Linear Solenoids

The open frame linear solenoid is the simplest linear solenoid design. It uses an open metal frame, a taped or overmoulded coil, and a movable plunger in the centre of the coil. Open frame solenoids are more cost effective than other linear solenoid types, and are typically selected for applications in which extremely long life and precise positioning are not so critical.

Open frame solenoids are available in two frame styles: the C Frame [or U Frame] style, in which the coil is enclosed on one side; and the D Frame [or Box Frame] style where the coil is enclosed on two sides.

OPEN FRAME LINEAR SOLENOIDS: Mechanism & Functionality

 

Open frame linear solenoids are a common type of linear solenoids. Linear solenoids are electromagnetic devices that convert electrical energy into a mechanical pushing or pulling force or motion. 

 

A linear solenoid consists of a cylindrical tube body, an electrical coil wound inside, and a plunger free to slide in and out of the coil’s body. By energizing the coil, solenoids can electrically open or close valves, operate mechanisms, and open doors and latches. 

 

Open-frame solenoids come in two frame options; C-frame or D-frame. They are devices with air gaps in their metal frames to provide heat dissipation.

Some application examples include:

  • Switchgear applications
  • Coin mechanisms
  • Mechanical devices

CURTISS WRIGHT'S RANGE OF LINEAR SOLENOIDS

Open Frame Linear Solenoids are typically divided into two categories:

  • C Frame (or U Frame) 
  • D Frame (or Box Frame)

Open frame linear solenoids are generally secured by mounting screws through a panel in the application and threaded into the solenoid’s frame.

 

C FRAME (U FRAME) LINEAR SOLENOID

C-frame solenoids, also called U-frame, are linear solenoids shaped like the letter 'C' or 'U.’ In C-frame solenoids, the coil is enclosed on one side; therefore, the magnetic field only flows through one side. These solenoids have a basic design and are often the smallest type available.

D FRAME (BOX FRAME) LINEAR SOLENOID

D-frame solenoids, also called Box Frame, are linear solenoids shaped like the letter 'D' (a Box). The coil is enclosed on both sides, allowing the magnetic field to flow through two sides. D-frame solenoids are of higher quality because of their balance between cost, performance, and size.
