Overview

The Nodehawk 4-Pin Relay set is a robust 12V DC switching solution designed for automotive, marine, and outdoor use. This 5-pack combines dependable relays with a ready-to-use wiring harness and extra-long 12 AWG tinned copper leads, offering solid, repeatable control for auxiliary circuits, lighting, pumps, and other 12V loads.

Built for durability in real-world conditions

Engineered with rugged caps and tight seals, these relays provide protection against water, dust, and moisture while remaining straightforward to install. Important note: they are designed for above-water use and should not be used underwater.

  • Water and dust resistance helps them stand up to harsh environments
  • Rugged construction supports vibration and temperature changes
  • Quick-install wiring harness simplifies replacement of worn relays

Quality materials that matter

The relay housing uses an industrial-grade composite, paired with high-purity copper coils to promote stable conductivity and consistent performance. The included wiring harness uses longer 12 AWG and 16 AWG tinned copper wire, which offers improved corrosion resistance compared to bare copper.

  • Nominal coil voltage: 12V DC; coil power: 1.8W; coil resistance: 80Ω
  • Operational range: 6–8V DC; release threshold: 0.6–3.6V DC; maximum voltage: 15.6V DC
  • Flame-retardant plastic base adds an extra layer of safety for electrical systems

Safety and installation considerations

The design emphasizes safe, reliable operation in demanding conditions, with clear guidance to respect rated current and voltage. If you need support, Nodehawk’s team is ready to assist with setup and compatibility questions.

What’s included in the 5-pack

  • Five 4-pin relays (12V DC, 40/30A)
  • Wiring harness with 12 AWG and 16 AWG tinned copper leads
  • Supportive documentation and access to customer assistance

This set blends practical durability with straightforward installation. It offers flexibility for a wide range of 12V circuits, and while it does not guarantee results in every application, it provides a solid, ready-to-use option for replacement parts in vehicles, boats, and outdoor gear.
