Quick Summary:
Our 2EDGK-3.81mm wire harness is a high-security interconnect solution featuring dual-screw mounting flanges for superior anti-vibration performance. Optimized for PLC control and heavy-duty machinery, this custom assembly ensures fail-safe signal transmission and robust mechanical locking in the most demanding industrial environments.
Product Overview
Our 2EDGK-3.81mm series wire harness is the gold standard for secure interconnectivity in demanding industrial applications. Unlike standard pluggable terminals, this “Flanged” version features integrated mounting ears on both sides of the connector, allowing it to be physically bolted to the mating header. This creates a fail-safe mechanical lock that prevents accidental disconnection caused by high-frequency vibrations, mechanical shocks, or cable tension. Integrated with high-grade UL-certified wiring and secondary precision connectors, this harness is the ideal choice for PLC control cabinets, heavy-duty machinery, and transportation electronics where consistent uptime is mandatory.

Key Features
Dual-Screw Mounting Flanges for Maximum Stability
The standout feature of the 2EDGK series is its dual-screw locking ears. By securing the plug to the header with screws, you eliminate the risk of “connector walking” or loosening over time. This provides an extra layer of mechanical insurance that friction-fit connectors simply cannot offer, making it essential for equipment with moving parts.
Vibration-Resistant Electrical Contact
Designed for the rigors of the factory floor, the internal clamping system maintains high-pressure contact with the pins regardless of external movement. This ensures low contact resistance and zero signal flickering, even when mounted directly onto high-vibration motors or industrial robotic platforms.
Precision Hybrid Interfacing
Our harnesses bridge the gap between heavy-duty terminal blocks and delicate internal PCB components. By pairing the rugged 2EDGK interface with smaller, high-density secondary connectors, we provide a pre-tested “Plug-and-Play” solution that simplifies complex internal wiring and reduces assembly labor.
Robust Strain Relief & Insulation
Every junction is reinforced with industrial-grade heat shrink tubing and precision-calibrated crimps. This protects the wire cores from physical fatigue at the exit points and provides excellent dielectric insulation, ensuring the harness survives years of service in hostile electrical environments.
Industrial Applications
Heavy-Duty Automation & Robotics
Used as the primary communication and power interface for robotic controllers and automated assembly lines that operate 24/7. The screw-lock feature ensures that the intense acceleration of robotic movements does not compromise the connection.
Transportation & Rail Electronics
Ideal for on-board monitoring systems in vehicles, trains, and maritime equipment where constant vibration and mechanical shocks are a standard part of the operating environment.
PLC Panel & DIN-Rail Integration
The preferred choice for high-end control cabinets. It allows for organized, screw-secured I/O connections that can be quickly serviced by unscrewing the flanges rather than re-wiring individual terminals.
Technical & Surface Performance
The 2EDGK housing is molded from high-performance PA66, offering superior heat resistance and impact strength. The terminal contacts are forged from copper alloy with thick tin plating to prevent oxidation in humid or corrosive industrial atmospheres. Every harness is 100% electrically tested for continuity and isolation, ensuring that your system’s “first-time-right” assembly rate is maximized.
Bespoke & OEM Manufacturing
We specialize in tailoring the 2EDGK harness to your exact mechanical footprint:
-
Flange Screw Customization: Choice of screw types to match your specific panel mounting requirements.
-
Complex Multi-Pin Layouts: Custom wiring sequences and color-coding for rapid error-free installation.
-
Environmental Shielding: Optional braided sleeves or foil shielding for applications requiring high EMI protection.
Production Process
Certified Terminal Assembly
Our production line utilizes torque-controlled assembly tools to ensure the mounting ears and internal clamping screws are set to optimal mechanical specifications without stripping the threads.
High-Fidelity Electrical Testing
We use advanced digital testing jigs to verify that every pin-to-pin connection is correct. This 100% inspection process includes resistance checks to guarantee high-quality signal flow across the entire harness.
Artisan Finishing & Labeling
Each harness is finished with durable, non-fading labels or heat-shrink marking. This allows your field engineers to identify specific circuits instantly, reducing maintenance time and operational risk.
FAQ
When should I choose 2EDGK (with ears) over 15EDGRK (without ears)?
You should choose 2EDGK if your equipment is subject to vibration, movement, or if you need to ensure the connector cannot be pulled out accidentally. The ears allow for a bolted connection to the panel or PCB.
Are the mounting screws included with the harness?
Yes, our 2EDGK harnesses typically come with the mounting screws pre-installed in the flanges for your convenience.
Is this connector compatible with Phoenix Contact and other major brands?
Yes, the 2EDGK-3.81mm is a standard industrial interface that is fully cross-compatible with 3.81mm pitch headers from Phoenix Contact, Degson, and other leading manufacturers.
Can you provide the harness with high-temperature wire?
Absolutely. While we use standard UL-certified PVC wire as a default, we can customize the harness with Teflon (PTFE) or Silicone wire for high-heat environments.
What is the benefit of the secondary micro-connector?
It allows for a clean transition between the rugged external interface (terminal block) and the sensitive internal electronics of your device, avoiding the need for direct-to-board soldering.
How do you ensure the terminals don’t oxidize over time?
We use high-purity tinned copper for all terminals and wire cores, providing a protective layer that resists corrosion even in salty or humid industrial conditions.
