unshielded
Product Overview
The M12 circular sealed connector uses A-coding for mating-error prevention. This configuration is a double-ended
panel-mount plug, providing excellent mechanical stability and electrical continuity for durable, reliable
connections in harsh industrial environments.
Key Features
- Standard M12 threaded coupling mechanism, compliant with IEC 61076-2-101
- Available in unshielded versions, high-strength all-plastic or metal housing, lightweight and durable
- High-grade flame-retardant PA66 Insulator material, rated UL 94 V-0
- Heavy gold plating on contact surfaces, ensures low Contact resistance (≤3mΩ) and extended mating life
