Modifications and Custom Capabilities
Three Tapped Holes in Armature Plate
Attachment screws used should not extend below the
bottom surface of the armature plate or they may
interfere with the rotary stroke.

Return Springs
Scroll Type Standard or Heavy Duty Fixed Springs
The primary purpose of the return spring is to return
the solenoid armature; it can also be used to return light
loads. Standard nominal settings, which are accurate to
within ± 20%, are charted below opposite “standard.”
Springs with greater torsion values can be supplied (see
values opposite “Heavy Duty” below).

Modifications and
Customized Units
For modifications
including heavy duty
return springs, drive pins,
etc. please contact our
application engineers for
assistance, as these
standard modifications
require a custom part
number.
And, if you can’t find
exactly what you’re
looking for among our
catalog products, please
give our application
engineers a call. Ledex
custom fabricated
solenoids are designed,
built, tested, packaged,
and shipped to your exact
specifications. Whether it’s
as simple as adding a
special connector or
mounting bracket, or
fabricating a complete
assembly, we can build the
right product to meet both
your design and budget
objectives.

How to Select Rotary Solenoids
1. Use the chart on page C9 to determine which coil style and
frame size best satisfies your application requirement. Turn to
the specification pages listed for model selection.
2. On the individual specification pages, use the Performance
Chart (like the one shown at right), to select one of the five
columns which provides the appropriate duty cycle for your
application (for example 25%). Reading down this column locate
the torque for the stroke you need.
3. Use the model number and configuration chart (like the one at
the bottom of this page) to select the model number
corresponding to your desired design, stroke, and direction of
rotation.
4. Using the Coil Specification Chart (like the one at right), find
your selected duty cycle column. Reading down this column
provides a variety of specification data. Following further down
the column into the VDC ratings, select the voltage which most
closely matches your supply voltage (for example, for a 24 VDC
supply, select 26.0). Read across to the left to select the coil awg
suffix for this voltage.
5. Replace the last two digits of the model number (XX) with the
coil awg number to complete the model number. (For this
example, specify model number: H-15039-033.

Rotary Solenoids Selection Overview
All data is at 20°C coil temperature. Torque outputs degrade with elevated temperatures.
1Without armature cover
2Torque values and energizing times shown for S and E Series are for Standard Life units. Long Life models provide
approximately 10% less torque, but offer 5 to 10 times longer life. Long Life models are only available in strokes up
to 45°.
* Consult factory for sizes and strokes not shown.
All specifications subject to change without notice.

How to Order
1. Using the Performance Chart to the left, select one of
the five columns which provides the appropriate duty
cycle for your application. Reading down this column
locate the torque for the stroke you need. For net
available starting torque, subtract return spring
torque of 0.12 lb.-in. ±20% (if torque is insufficient go
to next larger solenoid size).
2. Use the chart below to select the model number
corresponding to your desired design, stroke and
direction of rotation (as viewed from armature end,
opposite mounting studs).
3. Using the Specification Chart to the right, select the
same duty cycle column. Follow down the column into
the VDC ratings. Select the voltage which most closely
matches your supply voltage. Read across to the left to
select the coil awg suffix.
4. Replace the last two digits of the model number (XX)
with the coil awg number to complete the part
number.
