What is a Solenoid?

In its basic form, a solenoid is a long, thin tight coil of wire that produces a uniform magnetic field inside the coil pocket when an electric current is passed through it.

A Linear Electromechanical Actuator (LEMA), or simply Linear Solenoid, includes a plunger designed to fit into the solenoid coil pocket. This plunger is typically made from a ferrous square or round metal bar.

When an electrical current is passed through the coil of wire, it behaves like an electromagnet and the plunger is “pulled back” or attracted towards the center of the coil by the magnetic flux setup within the coil’s body.

It is generally spring-loaded so the plunger returns to its neutral position when the power to the solenoid is cut.

The concept of a linear solenoid is to convert electrical energy into a mechanical pushing or pulling force or motion, hence the term “electromechanical actuator”.

Generally, in engineering and in the context of Kabuki Drop systems, when the term solenoid is used, it refers to a linear solenoid.

The solenoid, which is cylindrical in shape, can be purchased at large general hardware stores or electronic parts stores.

Electronic “Pull Pin” Kabuki Drop

This a basic linear solenoid Kabuki Drop system that has a pin secured to the plunger in the form of a threaded rod that is screwed into the plunger head.

The solenoid cylinder is mounted and encased into a housing (a box made of plastic or metal) and the plunger pin extends out of the housing through a hole drilled through the side of the housing.

The entire housing is clamped onto a truss bar and this serves as the drop point for the Kabuki curtain.

The curtain is hung on the pins of the drop points via grommets fitted across the top edge of the curtain.

A cross section view of the solenoid cylinder is shown below.

When electricity is passed through these solenoids, the plungers retract into the housing, causing the pins to be pulled out of the Kabuki curtain which subsequently falls to the floor.

Electronic “Lever Release” Kabuki Drop

A linear solenoid can also be used to release a lever that holds up the Kabuki curtain instead of simply retracting a plunger pin as described in the basic solenoid system above.

It can also be used to pull open a gate latch or custom-fabricated arm.

Electronic “Shake & Drop” or “Rolling Pole” Kabuki Drop

This is a modern version of the traditional “rolling pole” Kabuki Drop but uses a linear solenoid to trigger a spring loaded gate latch to rotate the pole with drop points instead of a pull cord.

Check out a Double Kabuki Drop in action using an electronically-powered modern day “Rolling Pole” Kabuki Drop system in the video below:

One manufacturer that offers a variation of this system is Showtex. Their system is described in their operation manual here.

The Showtex system uses a solenoid system that drops an aluminum bar with drop points (pegs) at a downward angle to effect the curtain drop.

Electronic “Pins & Loops” Kabuki Drop System

The video below describes an electronic version of the “Pins & Loops” Kabuki Drop system. Instead of a pull cord as used in the manual version, this system uses a tensioned-spring to pull all the pins from the loops to release the curtain.

Unlike all other electronic systems, which requires the use of multiple individual solenoid drop point units, this system uses only one linear solenoid that keeps the spring pulled open when the Kabuki Drop is set up. When triggered, the solenoid releases the spring that pulls all the pins from the loops and activates the curtain drop.
