Pull/Push DC Solenoids for
Diesel Engines
Description
Murphy push/pull DC Solenoids
provide single unit versatility for engine
applications, such as shutdown.
A choice of two models and two
voltages is available. All models come
complete with return spring and rubber
seal boot. See the next page for
specifications and options.
Basic Models
Models RP2307B and RP2308B give a
full one inch (25 mm) stroke at 11
pounds (49 N) and hold up to 23 pounds
(102 N) at full voltage, continuous duty.
They will operate at any stroke less than
maximum; refer to the chart shown on
page 2.
Models RP2309B and RP2310B can
pull 14 pounds (62 N) with a one-and-ahalf inch (38 mm) stroke. They hold up
to 34 pounds (151 N) at full voltage,
continuous duty. See the chart on page 2
for holding force at any stroke less than
maximum.
SD85 Solenoid Drive
Time Delay
Using the SD85 ensures the energize
coil is only powered for 1-2 seconds
with each operation. If the plunger does
not seat in that time, it is highly
unlikely it will seat. The hold coil is
energized as long as the signal to the
SD85 is active. This insures long life of
the RP solenoid.

*Forces shown are without return spring. Forces shown < > are with return spring. Forces shown in [ ] are in kilograms.
**To determine the operating current, divide the power (watts) indicated in the above table by the applied voltage.
Solenoids will operate at any stroke less than maximum.

Note 1. Typical operating temperature for single 15 second operation of the energize coil is less than:
140°F(60°C) ± 10°F (6°C) for 1 in. (25 mm) Stroke Solenoids (70°F/21°C Rise above ambient)
120°F(49°C) ± 10°F (6°C) 1-1/2 in. (38 mm) Stroke Solenoids (50°F/10°C Rise above ambient)
See CAUTION statement on next page and note maximum housing temperature is 185°F (85°C).
Note 2. The energize-coil should not be activated for more than 15 seconds.
Longer energize-coil activation times will damage the solenoid.
Note 3. Allow minimum 15 minutes for cooling between activations of energize-coil to avoid damaging the
solenoid. (Depends on length of time energize coil is energized.)
Note 4. The energize-coil must fully seat the plunger to allow the hold-coil to function properly.
