PERMANENT MAGNET (Self Holding) SOLENOIDS1. Design and FeaturesThe permanent magnet solenoids (also known as mag-netic latching or self holding solenoids) is a product line of linear open frame solenoids that utilize the ad-vantages of a high performance permanent magnet. The principle of operation is similar to all linear solenoids. When the coil is energized, the plunger moves toward the pole piece. The advantage of the PM solenoid is that once energized and plunger movement has occurred, the plunger will remain in the energized position without any further electrical power input.This “holding” feature is accomplished because the permanent magnet creates a magnetic latching field that maintains the plunger in the closed or energized

rations : one is a single direction holding design and the other is a two direction holding design. The one direc-tion design uses a PM to hold the solenoid in the ener-gized position, Fig 1. The two direction design uses a PM that can hold the enclosed plunger in two different positions at both ends of the stroke. This is effected by the use of two separate coils and pole pieces, Fig 2.

2. Stroke, Force and Holding ForceThe PM type solenoids can be used in both short and long stroke applications. As such, the pole piece

the solenoid stroke should be minimized in the application.

3. Operational ConsiderationsA) TemperatureThe coil data for the permanent magnet solenoid shows the values at ambient temperature 20°C and a duty cycle of 25% (SH2LC0524 is duty cycle 10%). The solenoid coil can operate at temperatures up to 105̊C. Most applications using PM solenoids are intermittent applications (as the permanent magnet is used for holding). Please note the maximum on time to pre-vent potential thermal damage.B) OperationThe PM solenoid is different than traditional solenoids, in that electrical polarity is important to obtain proper operation. The lead wires from the coil are color coded and must be wired to the appropriate electrical connec-

in one direction (when energizing the solenoid) the

additive. To release the solenoid from the “hold” position,

C) Return SpringIn a one direction design it is advantageous to use a return spring to prevent inadvertent plunger “pull in” that could be caused by the magnetic field from the permanent magnet.

It is not recommended that the customer modify the plunger or shaft, as the shafts are manufactured and

supplied. Please consult the factory for details.E) HandlingThe permanent magnet solenoid utilizes a permanent magnet that will attract metal particles and care must be taken to prevent these particles from becoming “attached” to the solenoid.Fig. 2 Two Direction

F) Installation of SolenoidThe PM type solenoid uses tapped holes for mounting in the frame.Caution needs to be observed that the mounting screws used to attach these solenoids are the correct length so as not to damage the coil.

Expected life 200,000 cycles(Solenoid cycle life is very dependent upon side load, frequency of use, and environmental conditions.Cycle life tests should be performed by the customer.)

5. How to Select a SolenoidBefore selecting a permanent magnetic solenoid, the following information must be determined :A) Attraction Force and Holding ForceThe actual force required for both “pull in” and “hold-ing” in the application should be increased using a safety factor multiplier of 1.5 to arrive at the force value that

B) Duty CycleMost applications using PM solenoids are intermittent applications (as the permanent magnet is used for hold-ing), the duty cycle for each solenoid is shown in the catalog. Please note the maximum on time to prevent potential thermal damage.C) StrokeThe stroke for a one direction PM solenoid is deter-mined by application requirements. For a two direction PM solenoid the stroke is determined by the solenoid selected.D) Operating VoltageOperating DC voltage is determined by the application and voltage available.

correct size solenoid for the application, using the force-stroke characteristic tables and graphs. The coil data is also shown for different sizes of magnet wire. If the exact operating voltage is not in the coil data table, please consult the factory for details. Note: In a one

the plunger can return to the de-energized position the appropriate level of reverse current must be applied to the coil. The data for this “release” current is shown in the coil data given for each size solenoid.To determine the force output of the solenoid after temperature rise, please use the amp-turn force graphs (page 112) after calculating the amp-turns.

6. Ordering InformationWhen ordering a permanent magnet solenoid, the correct part number needs to be determined, from the catalog information.Example of a complete part number.SHILC0524-06 (One direction holding, conical face type and 6V coil)SH2LC0730-12 (Two direction holding, conical face type and 12V coil)

7. LabelingFor permanent magnet solenoids the part number labeling is as follows:

The solenoid label will have the part number and
