Overview

The Molex MC 12P MFE 16/12 TPE FLX connector (SKU 332020K04M120) is a 12-pole Micro-Change (M12) A-Code cordset featuring a TPE cable jacket. Designed for continuous-flex and welding cell applications, the TPE jacket resists weld slag and offers a +10M flex life for torsion and bending. The connector body is PUR with polyamide contact carriers, and the nickel-plated brass coupling nut provides secure mating. Contacts are copper alloy with gold over nickel plating for corrosion resistance. Rated IP67 and NEMA 6, it ensures reliable operation in harsh industrial environments. Operates at 250V AC/DC with 4.0A per contact, using 22 AWG PVC conductors.
