White-Rodgers 120-106131 Solenoid

The White-Rodgers 120-106131 is a high-performance 12VDC solenoid designed specifically for intermittent duty power switching in demanding electrical systems. This SPNO (Single Pole Normally Open) relay features a rugged construction with a continuous contact rating of 80 Amps and an impressive 400 Amp inrush capacity, making it a staple for high-torque starter motors and hydraulic pump circuits. Engineered with an isolated coil configuration, it prevents internal grounding issues common in vehicle chassis applications. The hardware includes a standard mounting bracket and high-conductivity copper contacts, ensuring minimal voltage drop under load. Technicians must note the duty cycle limits—typically 30 seconds on and 6 minutes off—to prevent thermal breakdown of the 6-ohm coil. Its dust and water-resistant housing maintains integrity in harsh engine room environments, while the #10-32 coil terminals and 5/16-24 contact studs provide secure, high-torque industrial terminations for reliable field service.

• High Current Handling: Manages 80A continuous and 400A inrush loads for heavy-duty starters and winches.
• Isolated Coil Design: Superior 12V DC isolated coil prevents accidental grounding and simplifies complex wiring.
• Environmental Protection: Dust and water-resistant enclosure protects critical internal copper contacts from contamination.
• Industry Standard Mounting: Includes a standard bracket for seamless drop-in replacement in existing brackets.
• Precision Control: Ideal for intermittent duty solenoid applications where precise power cycling is required.

Is the 120-106131 suitable for continuous duty applications?
No, this unit is an intermittent duty solenoid. Operating this part continuously will lead to coil overheating. For constant-on applications like battery isolation, use a dedicated 120 series continuous duty model.

How should this solenoid be oriented during installation?
To maximize longevity and prevent internal binding, it is best practice to mount the unit vertically with the coil terminals facing up or in a horizontal orientation.

What is the maximum run time for this solenoid?
The maximum "ON" time should not exceed 30 seconds, followed by a minimum 6-minute "OFF" period to allow for sufficient thermal dissipation.
