What’s a Solenoid Assembly?

Print anything with Printful



A solenoid assembly includes all parts of a standard solenoid-operated device, including the correct solenoid, connectors, controller, and external connections. It usually consists of two or three sections and may include kits with separate coils for different voltages and alternative mounting hardware. The correct solenoid part consists of a coil, plunger, and plunger return spring, with additional wiring and external linkages included in a wiring kit. The assembly includes all parts necessary to replace a faulty or damaged solenoid without reusing old parts.

A solenoid assembly is generally understood to mean all the parts of a standard solenoid operated device. The description of the assembly will typically be broken down into a component parts list, i.e. the correct solenoid, connectors and controller, and external connections. The solenoid itself usually consists of the coil with the preconnected leads, plunger, and plunger return spring. The wiring and controller section would include all assembly-specific external wiring such as extension cords or auxiliary device cables and any auxiliary or control devices considered to be an integral part of the unit. External linkages include all those motion transfer components that are not part of the actuated mechanism, but are required for solenoid installation.

Solenoids are inherently simple devices, with a solenoid assembly usually consisting of only two or three sections. In some cases, assembly components may be purchased separately to reduce replacement costs or as a complete unit for new installations. In most cases, the assembly consists of the solenoid itself and all peripheral components essential to its operation, but is not part of the device that the solenoid operates. These peripheral components generally include additional wiring elements, fasteners and connections. The term can also include kits that have separate coils for different voltages and alternative mounting hardware.

The correct solenoid part of a solenoid assembly consists of a coil, plunger, and plunger return spring. The solenoid coil usually has a mounting plate and a pre-connected set of power leads. Included in this section of the assembly are all of the standard fasteners that may be required to assemble the solenoid and electrical connectors or couplers used to insert coil wiring into a control circuit.

Any additional wiring to the solenoid assembly, such as wires for interlocks or limit sensors, will be included in a wiring kit, which may also include any control devices needed for the installation. External linkages are also an important part of many solenoid assembly kits. These will typically include all the locking links, pins and clips needed to transfer the solenoid output to the actuated mechanism that are not integral parts of the actuated mechanism. These linkage kits may also include extra parts designed to cover different models or design revisions of the activated mechanism. While it is difficult to pin down an exact description for a solenoid assembly, it is safe to assume that the assembly includes all the parts necessary to completely replace a faulty or damaged solenoid without having to reuse old parts.
