Low Profile Solenoids Linear actuation Space-saving, low-profile configuration Ideal for high force, short stroke applications All products are RoHS Compliant The low profile shape, besides contributing to smaller size, optimises the magnetic flux paths for maximum force versus stroke characteristics. The construction of the plunger assembly provides an auxiliary flux path which permits a significant increase in force. The low profile solenoid construction not only provides long life, but also provides a rugged design for both military and commercial applications. Flat Face: Higher efficiency for shorter strokes Ledex® Solenoids Conical Face vs. Flat Face Plunger Design Conical-faced designs extend the useful range of a solenoid to provide higher forces for strokes typically over 1.5 mm. The pole surface area is greater and the distance between the tapered cone faces is approximately one-half that of the gap between the land faces (for 30° angles), providing the effect of a closer air gap. Conical Face: Higher force for longer strokes While some of the force component is lost because the force vector is not parallel with the plunger motion, the shorter gap and higher flux density combine to provide more output force for longer strokes. For shorter strokes, the magnetic flux density increases and causes the iron to saturate rapidly as the poles move closer, thus reducing the efficiency of the conical-faced design. At this point, the flat-faced plunger is more efficient. The main advantage of the flat-faced pole over the conical is that the full component of force is usable because the force vector is parallel with the pole motion. Applications The reliability and high performance of Low Profile solenoids make them an ideal choice for applications in which consistent, reliable operation is critical. • Pumps • Machine tools • Packaging machines • Cranes • Instruments • Flow controls • Trucks and buses • Computer peripherals

Low Profile Solenoids Why Low Profile solenoids provide such high force and rapid response. A key to the efficiency and compact form factor of the low profile solenoid is our special precision coil-winding process. With maximum copper packed into the allowable space, each solenoid develops tremendous force for its size and power input. The low profile form, in addition to contributing to smaller size, permits maximum pole face surface area for the magnetic flux. Another factor that contributes to high efficiency is the additional iron surface on the external portion of the plunger; it provides...
