Product Features
Superior Waterproof Performance
Advanced triple-sealing design incorporates silicone rubber seals at the interface, cable entrance, and between connector components. The precision-machined threads and housing ensure complete environmental protection, meeting IP67 standards even after repeated mating cycles.

Enhanced Mechanical Durability
The zinc alloy metal shell provides exceptional impact resistance and mechanical strength. The strain relief system offers 360° cable protection, preventing damage from pulling, twisting, or bending stresses in industrial environments.

Optimal Electrical Performance
Gold-plated contacts (minimum 0.2μm thickness) ensure low contact resistance and stable transmission characteristics. The contacts are precision-stamped and formed to maintain consistent mating force throughout the product lifecycle.

Flexible Configuration Options
Available in straight and right-angle versions with cable lengths from 0.5 to 20 meters. Multiple color options (black, gray, blue) for easy circuit identification and system organization.

Easy Installation Design
Tool-free assembly with clear polarity marking and audible mating confirmation. The color-coded wiring system simplifies installation and reduces connection errors.

Environmental Resistance
UV-resistant cable jacket and oil-resistant connector materials ensure long-term performance in outdoor and industrial environments. Resistant to common chemicals, oils, and cleaning agents.

Product Advantages
Reliability in Harsh Conditions
The complete assembly is tested to withstand vibration up to 20G, mechanical shock, and temperature cycling, ensuring reliable operation in the most demanding industrial environments.

Reduced Installation Time
Pre-assembled and tested units eliminate field termination errors and reduce installation time by up to 60% compared to separate components.

Maintenance-Free Operation
The sealed construction and durable materials minimize maintenance requirements, providing years of trouble-free service even in washdown environments.

Cost-Effective Solution
Integrated design reduces total system cost by eliminating separate purchasing of connectors and cables, while the reliable performance reduces downtime and replacement costs.

Application Flexibility
Suitable for both power and signal applications, with multiple pin configurations available to meet various industrial requirements.

Enhanced Safety
The completely enclosed design prevents accidental contact with live parts, while the strain relief system prevents cable pull-out, ensuring safe operation in industrial settings.

Frequently Asked Questions (FAQ)

Q1: What is the difference between 3, 4, and 5-pin versions?
A: The 3-pin version is typically used for power applications, 4-pin for sensor connections, and 5-pin for industrial Ethernet or specific signal protocols. The choice depends on your application requirements.

Q2: Can the cable be replaced in field?
A: This is a pre-assembled unit designed for maximum reliability. While some field repair is possible, we recommend replacing the entire assembly to maintain waterproof integrity.

Q3: What is the bending radius of the cable?
A: The minimum bending radius is 5x the cable diameter for permanent installations and 10x for movable applications.

Q4: How do I ensure proper waterproof sealing?
A: Ensure the coupling nut is tightened to 0.6-0.8 Nm torque and visually inspect the seal for any damage before installation. The connector should mate with a smooth, firm action.

Q5: Can this be used in outdoor applications?
A: Yes, the UV-resistant cable jacket and IP67 rating make it suitable for outdoor use. For direct burial or continuous water immersion, please contact us for specialized solutions.

Q6: What is the delivery time for custom lengths?
A: Standard lengths are available from stock. Custom lengths typically require 2-3 weeks production time plus shipping.

Q7: Are these connectors compatible with major brands?
A: Yes, they follow international M12 standards and are compatible with most major industrial connector brands.
