Ledex & Dormeyer Products takes the short and long view of our customers' problems and the possibilities for solutions. This is why we're the world's leading solenoid manufacturer. And, it's what keeps us the best design source for solenoid solutions – whether it's one solenoid delivered tomorrow morning or a half million solenoids delivered just-in-time over the next year. When the process involves linear solenoids or rotary motion solenoids, we offer the best actuation devices in terms of size, cost, simplified installation, and ease of use. Below are some of the performance advantages and capabilities realized from solenoids. If your design includes linear or rotary operations, we can help you determine the best solenoid to meet your application design requirements.


Exceptional Force or Torque

A linear solenoid can provide up to 30 pounds of force from a unit less than 2-1/4 inches long. A rotary solenoid can provide well over 100 lb-in of torque from a unit also less than 2-1/4 inches long.


Variable Positioning

Soft Shift® solenoids for linear applications and BTA® Solenoid Actuators for rotary applications provide variable positioning capabilities.


High Speed

Solenoids can be actuated in milliseconds, or can be velocity controlled to provide smooth, noiseless actuation.


Minimum Size

Need low profile? Minimum volume? Small frontal area? Solenoids can pack more work per cubic inch than motors.


Simplified Control

Being a pulsed device with minimal components optimizes solenoids for digital control. This results in faster cycling and higher reliability with fewer interfaces.



Positioning applications utilizing solenoids can range from a simple ratcheting device to precise variable positioning.


Uncompromising Reliability

Ledex solenoids provide repeatable, predictable performance with a specified life of up to 100 million cycles.
