M12 B-Code Circular Metric Connectors

Amphenol LTW M12 B-Code Circular Metric Connectors offer 2 to 8 pins and feature a screw-thread mating style with complete 360° shielding. Compliant with IEC 61076-2-101, these connectors ensure industry-wide connector compatibility. Key features include a vibration-proof, corrosion-resistant design and a waterproof IP67/IP68/IP69K protection rating. Amphenol LTW M12 B-Code Circular Metric Connectors are suitable for wet and harsh environments, such as surveillance systems, mass rapid transit/railways, industrial automation, and broadband wireless access.
