Over 1,000 solenoid bobbin sizes are available.

The charts show a wide variety of over 1,000 plus solenoid bobbins available to General Linear Systems to assist you with your new solenoid coil design as well as your choice of bobbin.

Each of the chart icons represents a selection of bobbins in increments of .050". Choose the appropriate size bobbin ID and click the bar for bobbin ID.

General Linear Systems is one of the largest suppliers and designers of solenoid coils in the United States. Handling quantities of custom solenoids from 100 to 25,000 per month, from sizes from .150" O.D. to 2." O.D. of all types. Used in switching solenoid coils: electromagnetic devices, valve assemblies hydraulic and air, in the industrial and marine as well as in the medical field.

We have our own bobbin making capability and machine shop.

For R&D purposes, we have developed a computerized design program to design solenoids within minutes. All we need to know is what you need.
