M12 A-Code Circular Metric Connectors

Amphenol LTW M12 A-Code Circular Metric Connectors offer 2 to 17 pins and support push-pull and screw-thread mating styles. Features include complete 360° shielding, optimal signal performance with a Cat5e data transmission rate, and IEC 61076-2-101 compliance for industry-wide connector compatibility. Being vibration-proof, corrosion-resistant, and rated IP67/IP68/IP69K for waterproof protection, these connectors are ideal for wet and harsh environments. Suitable applications for the M12 A-Code Connectors from Amphenol LTW include surveillance systems, mass rapid transit/railways, industrial automation, and broadband wireless access.
