RP Series Pull/Push DC Solenoids

The Murphy Push/Pull DC Solenoids provide single unit versatility for engine applications, such as shutdown.

One solenoid offers pull/push operation. The RP Series has no internal switches, reduces coil burnout and reduces adjustments while boosting reliability. The solenoid offers high force in its small size. It can be used with most engines’ start systems. A choice of two models and two voltages is available. All models come complete with return spring and rubber seal boot. An SD85 Solenoid Drive Time Delay is also available to greatly reduce possibility of coil burnout and to facilitate low current-piloted operation.

Basic Models

Models RP2307B and RP2308B give a full 1 in. (25 mm) stroke at 11 pounds (49 N) and hold up to 27 pounds (120 N) at full voltage, continuous duty. They will operate at any stroke less than maximum; see the specifications tab. 

Models RP2309B and RP2310B can pull 17 pounds (75 N) with a 1-1/2 in. (38 mm) stroke. They hold up to 35 pounds (155 N) at full voltage, continuous duty. See specifations for holding force at any stroke less than maximum.


SD85 Solenoid Drive Time Delay

The SD85 is used when the solenoid is duty cycled for short time periods such as two-position throttle operation. It also provides enhanced operational control for normal on-off applications. Using the SD85 ensures the energize coil is only powered for one to two seconds with each operation. If the plunger does not seat in that time, it is highly unlikely it will seat. The SD85 activates both coils of the solenoid for a short time then de-energizes the Energize coil. The Hold-in coil is energized as long as the signal to the SD85 is active. This ensures long life of the RP solenoid.

Input voltage: 8 to 30 VDC. See specifications for current ratings.
