XC158A Series Circular Electrical Connector

XC158A Series Circular Electrical Connector | Military-Grade Waterproof & Heavy-Duty Interconnect

The XC158A series represents the pinnacle of rugged circular connector technology, engineered to maintain signal integrity and power delivery in the world's harshest conditions. From deep-sea exploration equipment to heavy-duty military communication systems, these connectors provide the "fit and forget" reliability required for mission-critical operations. Built with a dual-sided copper foil contact system, they ensure a gentle mating force while maintaining a gas-tight connection that resists corrosion and vibration.

Product Description

The XC158A Series Circular Electrical Connector is a high-performance interconnect solution designed to meet the rigorous demands of military and industrial applications. It features a robust, bayonet-style coupling mechanism that provides audible, tactile feedback upon full engagement, ensuring a secure lock even under extreme shock and vibration. Inside, the innovative dual-sided copper foil crimp contacts offer a larger contact area, resulting in lower contact resistance and higher current-carrying capacity compared to standard stamped contacts. Whether deployed in a naval warship or an automated drilling rig, the XC158A guarantees a sealed, stable, and durable electrical connection.

Specifications

Applications

• Marine & Subsea: Underwater cameras, sonar equipment, and navigation systems requiring waterproofing.
• Aerospace & Defense: Ground support equipment, avionics, and portable communication devices.
• Industrial Automation: Heavy machinery, robotic arms, and factory sensors in harsh environments.
• Oil & Gas: Drilling equipment and monitoring systems exposed to corrosive elements.
• Outdoor LED Displays & Lighting: Ensuring reliable power and signal transmission in all weather conditions.

Functionality

• Quick Bayonet Coupling: Provides a fast, secure, and vibration-proof connection with a simple push and twist motion.
• Crimp Termination: Ensures reliable, repeatable wire terminations suitable for automated manufacturing and field repairs.
• Five-Key Polarization: Prevents mismating of circuits in multi-connection panels, protecting sensitive electronics.
• "Waist-shaped" Mounting Holes: Offers greater installation tolerance and compatibility with various panel layouts.
• Anti-rotation Feature: Tail-end anti-rotation pin seats prevent the connector from twisting during cable tightening.

Key Features

• Dual-Sided Copper Foil Socket: Ensures smooth insertion/withdrawal forces while maintaining a highly reliable connection over many cycles.
• Hybrid Material Construction: Combines the strength of metal shells with the high-temperature resilience of silicone rubber seals and thermosetting insulators.
• Multi-Gauge Support: Accommodates wire sizes from Φ1mm to Φ3mm, allowing for mixed power and signal in a single connector.
• Flexible Mounting: Plugs and receptacles are designed for rotatable or fixed mounting options, with both male and pin configurations available.

Custom Design

We understand that one size does not fit all. The XC158A platform is highly adaptable for custom requirements:

• Mixed Contact Arrangements: Combine different contact sizes (e.g., power and signal) in a single shell.
• Custom Shell Finishes: Specify stainless steel for maximum corrosion resistance (1000hrs+) or specific anodizing colors for branding.
• Tailoring: Customize the length and type of cable assemblies, or integrate backshells for specific strain relief or EMI shielding needs.
• Keying Positions: Design unique polarization arrangements for your specific system architecture.

FAQ

Q: What is the waterproof rating of the XC158A?
A: When properly mated, the connector meets the requirements for IP67 equivalence, capable of withstanding immersion in 1 meter of water.

Q: Can I use this connector in high-vibration environments like on an engine?
A: Yes. The connector is specifically tested for sine vibration up to 2000Hz and random vibration (0.6G²/Hz), making it ideal for engines, pumps, and heavy machinery.

Q: What is the difference between the nickel-plated and anodized versions?
A: Nickel-plated versions offer superior EMI/RFI shielding, while hard anodized versions provide a durable, non-conductive, and wear-resistant surface. Stainless steel versions are also available for maximum corrosion resistance.

Q: Are these connectors RoHS compliant?
A: Yes, all materials used, including the copper alloy contacts and gold plating, are compliant with RoHS standards.

Q: Do you offer pre-assembled cable harnesses?
A: Yes, we offer full custom cable assembly services. Please contact us with your specific wiring diagram and cable length requirements.
