Versatile. Durable. Reliable.

Tubular Solenoids are ideal for applications that require long life and high reliability. Whether you’re in the Automotive, Smart Metering, Medical Devices, Business Equipment, Home Automation, Ventilation, White Goods, Power Tools, or Lawn & Garden Equipment industry, this solenoid can revolutionize your applications.


What’s new?

  • Molex® Connectors for easy install
  • Bar-code Traceability for enhanced QC
  • Made in USA to Reduce Lead Time

Pull & Push Configurations

In pull-type solenoids, the plunger is pulled into the solenoid when the coil is energized. Although push-type solenoids work in a similar way, the plunger has a shaft extension that pushes out through a hole at the end of the case.

Easy Installation with Molex® Connectors

Every Ledex Tubular Solenoid is equipped with an industry-standard Molex® connector, ensuring seamless integration into your application. The threaded nose and anti-rotation flat prevent movement, eliminating the need for external E-rings and impact washers that can interfere with attached mechanisms.

You can provide your own connections or use the included wire harness.

Bar-code Traceability for Enhanced Quality Control

Each solenoid undergoes rigorous end-of-line testing and is marked with a unique bar-code, ensuring traceability and unmatched quality control.

Unparalleled Service Life

With a typical service life of over 25 million cycles, Ledex Tubular Solenoids surpass the expected life of most equipment. Constructed with durable UL-approved materials and a built-in air gap spacer, these solenoids can withstand rigorous applications.

Made in the USA to Reduce Lead Time Risk

The latest generation of solenoids uses fewer components sourced from fewer suppliers, minimizing the potential for supply chain interruptions.


Extreme Temperature Functionality

Ledex solenoids can operate in extreme-temperature environments, with standard designs rated for -55°C–130°C (-67°F–266°F).

Expandability with Solligence™ Technology

Our next-gen Ledex solenoids are fully compatible with Johnson Electric’s Solligence™ technology, creating smart solenoids that consume less energy, produce less heat, and perform consistently throughout their service life. Enjoy predictive maintenance, IoT/Industry 4.0 capabilities, and other advanced data communication features.
