Lewmar Dual Direction Solenoid 0052531, 12V Reversing Contactor for Sprint 600/1000, Horizon 400/600/600F/900/900F & Pro Series Windlasses

The Lewmar Dual Direction Solenoid 0052531 is a 12 volt DC reversing contactor built for Lewmar electric windlasses that use permanent magnet motors. It is a changeover-type contactor, meaning a single unit switches the motor's polarity to drive the windlass in both directions, letting the anchor rode pay out and haul in from the same switch or helm control. This part is the direct replacement for the contactor inside the windlass control circuit, restoring proper up-and-down function when a worn or failing solenoid causes sluggish response, one-direction-only operation, or intermittent anchoring control.

Electrically, it is rated for a 12 volt DC coil and carries a 100 watt rating, with a minimum switching voltage of 12 volts DC, matching the demands of continuous-duty windlass motors. It ships as a single solenoid unit ready to wire into the existing control circuit, making it a straightforward service item for routine maintenance or troubleshooting an anchoring system that has stopped responding correctly. It fits Lewmar Sprint 600 and Sprint 1000, Horizon 400, 600, 600F, 900 and 900F, Pro Series, and Pro Fish windlasses, so it is a common replacement across several models in the Lewmar electric windlass lineup.

Frequently Asked Questions

What does the Lewmar 0052531 solenoid do? The Lewmar 0052531 is a changeover-type 12 volt DC contactor that reverses polarity to a permanent magnet windlass motor, letting a single control switch drive the windlass both up and down.

Which Lewmar windlasses use part 0052531? Part 0052531 fits Lewmar Sprint 600 and Sprint 1000, Horizon 400, 600, 600F, 900 and 900F, Pro Series, and Pro Fish windlasses.

What voltage is the 0052531 solenoid rated for? It is a 12 volt DC coil contactor with a minimum switching voltage of 12 volts DC and a 100 watt rating.

How much does the 0052531 solenoid weigh? The Lewmar Dual Direction Solenoid 0052531 weighs 2.13125 pounds.

What is included when I order part 0052531? The order includes one Lewmar 0052531 solenoid unit, ready to wire into the existing windlass control circuit.

Is this a genuine Lewmar part or an aftermarket equivalent? 0052531 is a genuine Lewmar solenoid, manufactured by Lewmar as the direct replacement contactor for its electric windlasses.

What symptoms indicate the windlass solenoid needs replacing? Sluggish response, one-direction-only operation, or a windlass that no longer responds to up or down commands point to a worn or failing contactor like the one replaced by Lewmar 0052531.

Does the 0052531 solenoid support both directions of windlass operation? Yes, it is a dual direction, changeover-type contactor, so the same unit switches the motor to run the windlass in reverse as well as forward.

Will this solenoid work with a permanent magnet windlass motor? Yes, the Lewmar 0052531 is designed for dual directional control of permanent magnet motors used in Lewmar electric windlasses.

Is the Lewmar 0052531 solenoid a changeover contact type? Yes, the contact type is changeover, which is what allows one contactor to control both the up and down direction of the windlass motor.
