M12 S-Code Circular Metric Connectors

Amphenol LTW M12 S-Code Circular Metric Connectors offer three or four pins and a screw-thread mating style. These robust connectors comply with IEC 61076-2-111 requirements, ensuring industry-wide connector compatibility. Amphenol LTW M12 S-Code Circular Metric Connectors are vibration-proof, resist corrosion, and are rated IP67/IP68/IP69K waterproof. These rugged features make the series ideal for wet and harsh environments, including industrial automation, surveillance systems, mass rapid transit/railways, and broadband wireless access.
