Maretron Mid Double-Ended Cordset Review

Let’s Dive into Maretron Mid Double-Ended Cordset

The Maretron Mid Double-Ended Cordset is a seemingly simple, yet crucial component for any NMEA 2000 marine network. Made by Maretron, a leader in marine electronic solutions, this cordset promises robust connectivity and reliable data transfer in demanding marine environments. It is a small gray cable, but it’s designed to keep all of your boat’s NMEA 2000 devices happily talking to each other.

I needed a reliable way to expand my boat’s network, adding a new GPS unit without compromising the existing connections. I’ve struggled with flaky connections on the water before, and losing GPS signal during a squall is not something I want to experience again.

My first impression upon receiving the Maretron Mid Double-Ended Cordset was positive. The overmolded connectors felt solid, and the cable itself had a reassuring heft. It felt noticeably more substantial than some of the generic NMEA 2000 cables I’ve used in the past.

I considered using a cheaper, no-name cable from an online retailer, but the horror stories of corrosion and signal loss steered me towards Maretron. Investing a bit more upfront for reliability at sea just makes sense.

My initial excitement was tempered slightly by the price, but the perceived quality and the peace of mind knowing it’s NMEA 2000 approved made it worthwhile. I hoped this cordset would deliver on its promise of robust and reliable connectivity.

Real-World Testing: Putting Maretron Mid Double-Ended Cordset to the Test

First Use Experience

I tested the Maretron Mid Double-Ended Cordset during a weekend sailing trip in the Puget Sound. The cordset connected my new GPS receiver to my existing Maretron backbone.

During the trip, we encountered everything from calm seas to moderate chop and even a brief rain squall. The connection remained stable throughout, with no interruptions to the GPS signal or data flow.

The cordset was exceptionally easy to use; it was basically plug-and-play. The connectors clicked securely into place, giving me confidence in the waterproof seal.

There were no issues to report from the first outing. The Maretron Mid Double-Ended Cordset simply performed as expected, providing a rock-solid NMEA 2000 connection.

Extended Use & Reliability

After several months of regular use, the Maretron Mid Double-Ended Cordset continues to perform flawlessly. It has been exposed to saltwater spray, direct sunlight, and significant temperature fluctuations without any noticeable degradation.

The cordset shows no signs of wear or tear, and the connectors still feel as solid as the day I installed them. I periodically inspect the connections for any signs of corrosion, but so far, everything looks pristine.

Maintaining the cordset is simple; I occasionally wipe it down with a damp cloth to remove any salt residue. Compared to some of the cheaper cables I’ve used previously, the Maretron cordset is proving to be far more durable and reliable.

This Maretron Mid Double-Ended Cordset outperformed my expectations. I now have zero concern about a loss of connection due to a poorly made cable.

Breaking Down the Features of Maretron Mid Double-Ended Cordset

Specifications

• Contact Carrier Material/Color: Thermoplastic PUR/Blue-Gray – This material provides excellent resistance to chemicals and UV degradation in the harsh marine environment. The blue-gray color matches the Maretron standard, allowing for quick identification within a larger network.
• Molded Body Material/Color: Thermoplastic PUR/Blue-Gray – Matching the contact carrier material, the molded body ensures consistent durability and resistance to environmental factors. The robust construction protects the internal connections from physical damage.
• Contact Material/Plating: Brass/Gold – The brass base provides excellent conductivity, while the gold plating ensures corrosion resistance and a reliable electrical connection. This is crucial for maintaining stable data transfer in a saltwater environment.
• Coupling Nut Material/Plating: Brass/Nickel – The brass nut provides strength, and the nickel plating ensures long-term corrosion resistance for a reliable seal. This is essential for creating a watertight connection.
• Connector Outside Diameter: 0.59″ – This compact size allows for easy installation in tight spaces, minimizing the footprint of the connections. It’s a manageable size for routing and connecting multiple devices.
• Current Rating: 4.0 Amps – This current rating is sufficient for most NMEA 2000 devices, allowing the cordset to power and transmit data simultaneously.
• Voltage Rating: 250 V – The voltage rating far exceeds the typical voltage used in NMEA 2000 networks, providing a safety margin and ensuring compatibility.
• Outer Jacket Material/Color: PVC/Gray – The PVC outer jacket provides excellent abrasion resistance and protects the internal conductors from damage. The gray color is standard for Maretron NMEA 2000 cables.
• Conductor Insulation Material: PE (data pair) PVC (power pair) – Using PE (Polyethylene) for the data pair provides excellent signal integrity, and PVC for the power pair offers robust insulation. This design optimizes both data transfer and power delivery.
• Number of Conductors: 2×16 (1.29mm) AWG Data 2×20 (0.81mm) AWG 20 (0.81mm) AWG Drain Wire – The use of larger gauge wires for the power pair minimizes voltage drop over longer cable runs, especially important in a voltage drop sensitive network. The dedicated drain wire improves shielding and grounding.
• Shielding (3 Levels): Alum/Polyester Foil (Overall) Foil (Power Pair) Foil (Data Pair) – Three levels of foil shielding minimize electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring clean data transmission. This is particularly important on boats with multiple electronic devices.
• Protection Class: IEC IP68 NEMA 1346P – This high IP68 rating guarantees complete protection against dust and prolonged immersion in water, crucial for marine applications. The NEMA rating further reinforces this protection.
• Temperature Rating: -40 deg C to 80 deg C to (-40 deg F to 176 deg F) – This wide temperature range ensures reliable performance in extreme climates, from frigid winters to hot summer days.
• Approvals: (Cable) UL: PLTC 75 deg C Sunlight Resistant E90625 AWM 80 deg C 300V, (Cable) CSA: CMX-OUTDOOR-CMG LL54185 75 deg C AWM I/II A/B 80 deg C 300V FT4, NMEA: NMEA 2000 Approved, IEC: IEC 61162-3 – These certifications confirm that the cordset meets industry standards for safety, performance, and compatibility with NMEA 2000 networks.

Performance & Functionality

The Maretron Mid Double-Ended Cordset excels at its primary function: providing a reliable and robust NMEA 2000 connection. The larger power wires minimize voltage drop, allowing for longer cable runs without signal degradation.

One potential weakness could be its relatively short length (0.5M); longer runs might require additional cordsets and connections. However, this length is ideal for connecting devices in close proximity.

The cordset definitively meets expectations. It provides a stable, waterproof connection, and the larger gauge power wires offer a real advantage over standard micro cables in networks with longer runs.

Design & Ergonomics

The build quality is excellent, with robust connectors and a durable cable jacket. The size and weight are appropriate for its intended use; it feels solid without being bulky.

The cordset is exceptionally user-friendly. The connectors are easy to grip and securely lock into place.

Durability & Maintenance

Based on my experience so far, the Maretron Mid Double-Ended Cordset is built to last. The high-quality materials and robust construction suggest it will withstand the harsh marine environment for many years.

Maintenance is minimal, requiring only occasional cleaning to remove salt and debris.

Accessories and Customization Options

The Maretron Mid Double-Ended Cordset does not require any specific accessories; it is a self-contained connectivity solution. However, it is fully compatible with all standard NMEA 2000 connectors and devices.

Maretron offers a range of other NMEA 2000 components, such as T-connectors, terminators, and power cables, which can be used to create a complete and customized network. The cordset integrates seamlessly with these components.
