Security Solenoids

Guardian Electric Manufacturing Co., a division of Kelco Industries, offers an industry leading variety of standard and custom designed Solenoids and custom electromagnetic coils.  We offer Solenoids in push or pull types and magnetic latching designs.

To maintain the highest level of quality we manufacture the key components of every solenoid. We mold our own coil bobbins and wind our coils.  We also have state-of-the-art machining capabilities for manufacturing all custom components.

Our standard solenoids can be modified to fit a particular application, or we can design a new solenoid to meet a specific requirement.

Available options:

  • Custom voltages

  • Value added packages.

  • Custom plungers

  • Spring returns

  • Custom mounting & terminations

    DC Latching Solenoids

    Latching Solenoids from Kelco Industries are designed for applications that require the holding force to be maintained without having power applied. The plunger will remain latched, in-place, and seated to the plug inside the solenoid with the specified “holding force.” To release the plunger, the polarity of the applied voltage must be reversed. These solenoids…
