SMALL PUSH-PULL SOLENOIDS
1. Design and Features

The small push-pull solenoids have the same features
as the conventional push-pull solenoid. The push-pullsolenoid design utilizes a coil with the maximum
amount of magnet wire in the smallest amount ofspace. This coil assembly is then packaged in a metal
housing using highly permeable steel to obtain themaximum force in the minimum size and weight. Thissmall size solenoid is a very cost eﬀective solution
when small movements are required and/or limited
amount of electrical power is available.

installed to prevent the armature and base from coming
into mechanical contact with each other, which would
cause residual magnetism.
C) Return Spring
The small push-pull solenoid does not include a return
spring. Therefore, the application must include a return
spring.
It is not recommended that the customer modify theshaft, as the shafts are fabricated before assembly. Any
special conﬁguration can be supplied. Please consult
factory for details.
E) Installation of Solenoid
The small push-pull solenoid uses tapped holes for
mounting in the base.
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.
4. General Characteristics
Insulation class

2. Stroke and Force

The conical pole piece conﬁguration is the standard
design for the small push-pull solenoid. For the bestminimum.
3. Operational ConsiderationsA) Temperature
The coil data of small push-pull solenoids shows thevalues at ambient temperature 20°C and without theuse of a heat sink. If a solenoid is used at a rating
shown in the coil data, it is designed so that the coiltemperature rises and reaches equilibrium at approximately 85°C. In applications where the ambient temperature is higher than 20°C possible thermal damage
can occur. Temperature rise tests should be performedby the customer to assure that the coil does not reach
120°C. Coils can be constructed to operate at temperatures higher than 120°C without thermal damage.
Please consult the factory for details.
B) Air Gap Spacer
The small push-pull solenoid uses an air gap spacer
between the armature and the case. This spacer is44

Expected life
Standard life : 5 million 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 Solenoid

Before selecting a small push-pull solenoid, the following information must be determined :A) Force
The actual force required in the application should beincreased using a safety factor multiplier of 1.5 toarrive at the force value that should be used in yourB) Duty Cycle
Use the aforementioned formula to calculate dutycycle. Also note the maximum on time. (See page 2)

SMALL PUSH-PULL SOLENOIDSC) Stroke
Stroke is determined by application requirements.
D) Operating Voltage
Operating DC voltage is determined by the applicationand voltage available.

B ) S peci al C onf i gur ati on ( r equi r ed f or any modi f i cation to a standard design)
Any change from the standard catalog design
requires that a custom part number be assigned,
which will also include the date code of manufacture.

correct size solenoid for the application, using theforce-stroke characteristic tables and graphs. The coil
data is also shown for diﬀerent sizes of magnet wire. If
the exact operating voltages are not in the coil datatable, please consult the factory for details.
To determine the force output of the solenoid after
temperature rise, please use the amp-turn force graphs(page 60) after calculating the amp-turns.

6. Ordering Information

When ordering a small push-pull solenoid, thecorrect part number needs to be determined from thefollowing combination of characteristics (1-3) :(1) M-Metric Thread
F-SAE Thread(2) Solenoid Size (example-144C)(3) Coil voltage from tables (At 100% Duty cycle)
Example of a complete part number.
(1) (2) (3)M 144C-6V
This part number is for a solenoid with Metric threads,size 144C, with a 6V coil.
7. Labeling

For small push-pull solenoids the part number labelingis as follows :The solenoid label will have the part number andmanufacture).
