Turck RKSW D9SM 456-1M Profibus DP Interface Cordset

Turck RKSW D9SM 456-1M PROFIBUS-DP Interface Cordset is a shielded, single-ended cable assembly that provides a direct M12 × 1 female, straight, B-coded, 5-pin to D-Sub male, 9-pin, right-angle connection for PROFIBUS-DP communication networks. Identified as U7957-1 (Product #208571), this 1 m cordset supports PLC control panels, distributed I/O, conveyor lines, packaging and process automation equipment requiring reliable M12-to-D-Sub connectivity. Key specs include conductors 2 × 0.34 mm² (22 AWG), a violet PUR jacket, overall jacket diameter 7.9 mm, and shielding of aluminum foil with tinned copper braid (shield connected to the connector), with a characteristic impedance of 150 Ω. It is rated for 250 V and 4 A, and uses gold-plated CuZn contacts with a nickel-plated brass coupling nut. Protection ratings are IP67/IP69K when the M12 is mated and IP20 on the D-Sub side, operating temperature from -40 °C to +80 °C, and approvals include UL Listed, CSA, CE, and RoHS. Common applications span PROFIBUS-DP automation networks in industrial control panels, robotic work cells, packaging and bottling lines, conveyor and material handling systems, with system integrators and maintenance teams relying on it for equipment replacement, retrofits, and network expansion.
