Machine and process automation can range from the most basic on-off function to extremely complex sequencing. When the process involves linear or rotary motion, solenoids are among the best actuation devices in terms of size, cost, simplified installation, and ease of use. Below are some of the primary functions which are ideally suited for Ledex solenoids. 

• Pinch: In medical equipment, tubes carrying body fluids must have accurately controlled flow regulation. In this example, a Soft Shift solenoid is utilized for its variable positioning capability to smoothly pinch the tube to the operator's precise demand. Using a solenoid in this manner eliminates valves and other connecting apparatus which pose a threat for contamination or leakage
• Gate: Gate diverters, depending on the application, can be used continuously or very infrequently. In this example, a BTA^® unit is chosen for its 100+ million actuation life rating
• 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 for linear applications and BTA^® Brushless Torque 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? Ledex 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
• Uncompromising Reliability: Ledex solenoids provide repeatable, predictable performance with a specified life of up to 100 million cycles
• Kick: Solenoid snap-acting response and electric operation are beneficial for part rejection processes in which electronic interfacing with a photosensor or some other sensor is required
• Lock/Latch: Low cost, compact size, reliability, and long life are all reasons for the growing demand for Ledex solenoids in a wide variety of locking applications from vault doors, cash registers, disk drives and missile systems
• Position: Positioning applications can range from a simple ratcheting device, such as this, to precise variable positioning using linear Soft Shift^® or rotary BTA^®actuators
  

So if you have any of the following applications then this might be the right choice for you!
