Solenoid for 36 V DC systems

The White-Rodgers 70-120224S1 is a DC power solenoid rated for 36 V coil voltage and 50 A current capacity. It uses an SPST-NO contact form with copper contact material and an isolated coil type. This component suits industrial electrical controls and automation tasks requiring reliable switching.

Continuous duty performance

The solenoid carries a continuous duty cycle with a coil resistance of 114 ohm and dielectric strength of 500 V. Electrical operating durability reaches 100, 000 cycles while mechanical operating durability extends to 250, 000 cycles. Maximum operating temperature is 122 Degrees F under sustained operation.

Verify coil voltage and thread sizes

Confirm your control circuit supplies exactly 36 V DC to match the coil specification. Check that contact termination uses 5/16 in-24 UNF-2A thread and coil termination uses #10-32 UNF-2A thread. Ensure the 2.4 in height and 2.47 in length fit the available mounting space.

Questions about this item

How much heat does the 36 V coil generate during continuous duty?

The coil resistance is 114 ohm and the maximum operating temperature is 122 degrees F, so the solenoid is rated for continuous operation at that temperature.

What thread sizes are needed on the power cables and coil wiring?

Power contacts use 5/16 in-24 UNF-2A threads and coil terminals use #10-32 UNF-2A threads.

Will the 2.47 in length and 2.4 in height fit inside my existing 70-series mounting bracket?

The solenoid measures 2.47 in long by 2.4 in high, matching the series 70 envelope used in earlier White-Rodgers designs.
