A single analytical instrument utilizes as many as 100 solenoids. The collective power consumption of all these solenoids was of great concern for the machine developer.

Their solution was the Ledex STA^® Tubular Solenoid. The magnetic latching design uses power only to initiate movement of the solenoid plunger to the energized position where it is held in position indefinitely by an internal magnet. To return the plunger to its home position, a negative electrical pulse is applied to unlatch the tubular solenoid.

In the food processing industry, high speed / high pressure water jets are used to cut poultry and fish.  Due to the unique features of speed, reliability, and compact size, a manufacturer of food processing equipment has selected a size 4, 30 degree Ultimag^® Rotary Solenoids for its newest generation of equipment.

The customer had an application in which there was a need to open the door to vent large industrial ovens, but was unable to use a motor as the door must be able to be closed manually.  The Size 150 Tubular Solenoid was selected, as it can be pushed back to the starting position in a manual override situation, with no resulting damage.

The Size 150 Tubular Solenoid, for long stroke, high force applications, is among the most powerful Tubular Solenoids offered by Ledex Products.  The maximum torque at low duty cycles surpasses 20 pounds and can operate at strokes as long as 1 inch.

Ledex’s popular B16-L and B17-L latching open frame solenoids are now RoHS compliant. They feature an integral return spring and are specifically designed for latching applications such as security systems, office automation and medical devices.

These compact solenoids provide a maximum force of 25 oz. and a maximum stroke of 0.18 inches in a compact housing less than one inch in length and less than 0.6 inches in width. They offer 10%, 25%, and 50% duty cycles and are available as standard with 3, 6, 12 or 24 VDC input voltages, with optional input voltages up to 120 VDC.   Two plunger cone configurations are available.
