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-pull
solenoid design utilizes a coil with the maximum
amount of magnet wire in the smallest amount of
space. This coil assembly is then packaged in a metal
housing using highly permeable steel to obtain the
maximum force in the minimum size and weight. This
small 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.
D) Shaft Modification
It is not recommended that the customer modify the
shaft, 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
Fig. 1
2. Stroke and Force
The conical pole piece configuration is the standard
design for the small push-pull solenoid. For the best
performance efficiency, the stroke should be kept to a
minimum.
3. Operational Considerations
A) Temperature
The coil data of small push-pull solenoids shows the
values at ambient temperature 20°C and without the
use of a heat sink. If a solenoid is used at a rating
shown in the coil data, it is designed so that the coil
temperature 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 performed
by 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 is

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 be
increased using a safety factor multiplier of 1.5 to
arrive at the force value that should be used in your
specification.
B) Duty Cycle
Use the aforementioned formula to calculate duty
cycle. Also note the maximum on time. (See page 2)
www.shindengen.co.jp/smt/
SMALL PUSH-PULL SOLENOIDS
C) Stroke
Stroke is determined by application requirements.
D) Operating Voltage
Operating DC voltage is determined by the application
and voltage available.
Example :
F94010P
9401
Small Push-Pull Solenoids
After determining these specifications, one can find the
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 voltages are not in the coil data
table, 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.
B) Special Configuration (required for any modification 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.
Special Part Number
Date Code (year and week)
6. Ordering Information
#W hen ordering a small push-pull solenoid, the
correct part number needs to be determined from the
following 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 labeling
is as follows :
A) Standard Solenoid (no modifications).
The solenoid label will have the part number and
the date code (which identifies the year and week of
manufacture).
Example :
