Structure And Preponderance

• Push/pull solenoid is designed to obtain maximum force, however with minimum size and weight. Its coil is covered by high permeability metal. And its plunger is with a design of supporting magnetic polarity. To comparing plunger withoutsupporting magnetic polarity design, the force is increased by 20-50 which can achieve very good performances.
  
• Besides, the height of push/pull. Solenoids is only 1/2 of its outer diameter.
  
• Space is saved by this flat structure.
  
• Push pull solenoids are divided into cone ( C ) type and flat ( F ) type. Please refer FIG.1 and FIG.2. If middle-long stroke is required, please use C type. To require short stroke or strong force, please use F type.

FIG. 1 CONE TYPE ( C )

FIG. 2 FLAT TYPE (F)

Points To Be Considered When Operation

1. CONCERNING TEMPERATURE
   The values of push/pull solenoid coil data are based on ambience temperature 20?, and plating on standard heat sink.
   
   And coil data is defined when rated operation, temperature rise 85°C Max. In case of too high ambience temperature or too small heat sink, please decrease duty cycle or operation voltage. Coil temperature must not exceed 120°C.
   
2. CONCERNING PROCESS OF SHAFT
   When users process on shaft (Material: Stainless), do protect metal cutting powder from adhering on slot of plunger. As life will be decreased seriously due to metal powder.
   
3. AIR GAP SPACER
   There's a spacer between plunger and case for air gap. When releasing, the spacer is to avoid residual magnetism. Do not forget it during assembly.

Methods Of Selection
To choose suitable push/pull solenoids, please determine followings:

1. PULL FORCE
   Besides load, it's necessary to also consider variation of temperature and voltage. Therefore, please time, load by safety coefficient 1.5 x.
   
2. DUTY CYCLE
   Besides on time and off time, please also note Max. on time.
   
3. STROKE
   To define required stroke.
   
4. OPERATION VOLTAGE
   To define coil input DC voltage.
