Product Features
Revolutionary Quick Self-Locking Mechanism
The patented push-pull locking system enables one-handed operation with audible engagement confirmation. The bayonet-style coupling ensures vibration-proof connections that won't loosen under extreme conditions, while the anti-decoupling sleeve prevents accidental disconnection.

Superior Environmental Protection
Rated IP68 for complete protection against dust, water, and chemical ingress. Multiple silicone seals and precision-machined interfaces maintain integrity under high-pressure washdowns, submerged conditions, and exposure to oils, solvents, and coolants.

Advanced Electrical Performance
8/9-pin configuration with gold-plated contacts (0.5μm thickness) ensures optimal signal integrity and power transmission. The 360° braided shielding provides excellent EMI/RFI protection, making it suitable for sensitive analog signals and high-speed data transmission.

Robust Mechanical Design
High-strength composite housing with stainless steel coupling mechanism offers exceptional impact resistance and durability. The connector withstands mechanical stress, crushing forces, and repeated mating cycles without performance degradation.

Intuitive User Experience
Color-coded pins and keyed alignment prevent mis-mating, while the ergonomic design allows for easy handling even with gloves. The visual and tactile feedback system confirms proper connection status.

Maintenance-Friendly Design
Field-replaceable contacts and seals reduce downtime and maintenance costs. The tool-less assembly and disassembly simplify field servicing and cable replacement.

Product Advantages
Unmatched Operational Efficiency
The quick self-locking mechanism reduces connection time by 70% compared to Threaded Connectors, significantly improving installation efficiency and reducing labor costs in large-scale deployments.

Enhanced System Reliability
Superior environmental sealing and vibration resistance minimize connection failures and maintenance requirements, ensuring continuous operation in critical industrial applications.

Future-Proof Compatibility
Designed to support both current and emerging industrial protocols, including Ethernet IP, PROFINET, EtherCAT, and various sensor signals, providing long-term compatibility and investment protection.

Cost Optimization
Reduced installation time, lower maintenance requirements, and extended service life contribute to significantly lower total cost of ownership compared to traditional Industrial Connectors.

Safety Excellence
The positive locking mechanism and superior insulation properties ensure operator safety and system protection, meeting international safety standards for industrial equipment.

Frequently Asked Questions (FAQ)

Q1: How does the quick self-locking mechanism work?
A: The mechanism uses a patented push-pull design - simply push the connector until you hear an audible click, and pull the locking sleeve to disconnect. No twisting or tools required.

Q2: What is the difference between IP67 and IP68 rating?
A: IP68 offers superior protection - while IP67 protects against temporary immersion (1m for 30min), IP68 guarantees continuous underwater operation (2m for 24 hours in our case).

Q3: Can I use this connector for both power and data transmission?
A: Yes, the 8/9-pin configuration allows mixed use of power and signal contacts, supporting up to 7A per power contact and 100Mbps data transmission.

Q4: How does the connector perform in high-vibration environments?
A: Excellent. The vibration resistance (15g, 10-2000Hz) and positive locking mechanism ensure reliable performance in even the most demanding vibration conditions.

Q5: Are custom pin configurations available?
A: Yes, we offer custom pin assignments and special configurations for specific application requirements. Contact our technical team for customization options.

Q6: What maintenance is required?
A: Minimal maintenance needed. Recommend periodic inspection of seals and contacts, with easy field replacement of wear parts if required.

Q7: Is the connector compatible with existing systems?
A: While designed for superior performance, it maintains compatibility with standard industrial interfaces. Adapters are available for legacy system integration.
