B&R Industrial Automation X67CA0X21.0050 Link Attachment Cable

X67CA0X21.0050 is a 5-meter X2X Link attachment cable for B&R’s X67 system, featuring an M12, 4-pin connector and a straight mating end, designed to interconnect X2X modules with robust EMI protection. The violet TPU outer jacket is halogen-free and flame-retardant, with pair shielding using aluminum foil and a tin‑copper braid with >85% coverage to guard data lines from interference. It carries two data conductors (2 × 0.25 mm²) and two power conductors (2 × 0.34 mm²); data wires are 19 × 0.13 mm and power wires 19 × 0.15 mm, with color coding blue/white for data and red/black for power. Electrical ratings include 250 V nominal, up to 4 A at 40°C, and a maximum operating voltage of 250 V, with insulation category II per IEC 61076-2. The cable diameter is 6.9 mm ±0.3 mm and it weighs 0.063 kg/m; it is IP67 only when screwed in. Designed for drag-chain operation, it supports up to 4 m/s² acceleration, a minimum of 2 million flex cycles, and a maximum speed of 3 m/s, with bend radii of 5× outer diameter for fixed installation and 15× for flexible use. Operating temperatures range from -40 to 80°C (fixed) and -25 to 60°C (flexible).
