Cole Hersee Solenoids

When it comes to heavy-duty electrical control in demanding commercial vehicle and marine environments, Cole Hersee has built a legendary reputation for engineering solenoids that deliver reliable performance under the most challenging conditions. Since Cole Hersee was founded in 1924, they have been a pioneer and leader in the development of heavy-duty electrical products for the vehicle industry, and their solenoid lineup exemplifies this nearly century-long commitment to quality.

Continuous Duty Engineering for High-Current Applications

Cole Hersee intermittent and continuous solenoids provide safe, dependable control of electrical systems on all type of DC low voltage vehicles. The company's continuous duty solenoids are specifically designed to handle sustained high-current loads without overheating or performance degradation. Cole Hersee's Continuous Duty Solenoid is an insulated continuous duty solenoid used in a direct current wiring system between a low current capacity switch and a high current load requirement, making them essential components for applications ranging from winch operations to battery management systems.

The Cole Hersee continuous duty solenoids are solidly built and are well-respected in the RV community, where reliability isn't just a convenience—it's a necessity. These solenoids feature ratings from 65A to 200A continuous duty, with voltage options spanning 6V, 12V, 24V, and 36V configurations to accommodate diverse electrical system requirements.

Insulated Design and Premium Materials

A hallmark of Cole Hersee solenoids is their insulated construction. The solenoid is insulated, with studs electrically isolated from the housing, making it suitable for handling high current loads. This design prevents electrical shorts and enhances safety in environments where vibration, moisture, and temperature fluctuations are constant challenges.

Cole Hersee employs Single-Pole, Single-Throw (SPST) circuitry with normally open contacts in most of their continuous duty models, utilizing copper contacts in standard applications and silver contacts in heavy-duty models rated for 200A and above. The solenoids feature copper power studs with 5/16"-24 threading for battery and motor connections, while steel coil studs with 10-32 threading handle control circuits. Many models include PVC coating for additional environmental protection, extending service life in harsh marine and industrial settings.

Versatile Applications Across Industries

They are ideal for marine applications and for forward and reverse systems in golf carts, garden tractors, fork lift trucks and winch operation. Beyond these uses, Cole Hersee solenoids serve critical roles in battery isolation systems, emergency vehicle equipment, and any application requiring remote switching of heavy electrical loads. By using a solenoid, the amount of heavy wiring needed to power the load is reduced, since the control circuit mounted inside the cab typically utilizes a smaller wire gauge, improving both safety and installation efficiency.

Cole Hersee also offers specialized latching solenoids that require only momentary coil power to operate, generating minimal heat since the coil de-energizes when the solenoid is "ON"—a critical advantage in applications where power consumption and heat management are paramount concerns.
