Phoenix SACC-M12FS Series Industrial M12 Female Connectors Selection Guide

Opening: Specialized Female M12 Connectivity for Industrial Ethernet, Power & Signal Transmission

The Phoenix SACC-M12FS series represents industrial-grade female M12 connectors engineered to complement male counterparts in automation, industrial Ethernet, and power control systems. Featuring seven functional sub-series (FSX/FST/FSS/FSL/FSD/FSB/FS) with tailored designs for PROFINET/Ethernet communication, power distribution, and harsh-environment operation, these connectors offer multi-core configurations (2/3/4/5/8-core), specialized coding (QO/Q/CT), flexible interface options (PG9/11, DM 5-8), and critical certifications (PROFINET PN, Ethernet ETH, Australian AU, voltage VA). Designed for seamless integration with sensors, PLCs, IIoT gateways, and industrial Ethernet devices, they ensure reliable signal/power transmission with industrial-grade durability (IP67 protection when mated, -40°C to +85°C operating range) and protocol compliance.
