Cable assembly specs that decide fit
The 3RK1902-2NB50: This is a 5-meter M12-to-M12 cable, both ends angled with a plug connector, 4-pin, rated 4 A per pin at 60 V AC/DC max — the current ceiling per conductor, not the overall assembly rating. The PUR jacket (6.7 mm OD) and thermoplastic polyurethane enclosure resist mineral oil, grease, and water — conditional per application, but the material choice targets machine-tool and washdown zones where PVC would soften. Shielded with tinned copper braid, 100 Ω characteristic impedance at 100 MHz — this is a PROFIBUS-style cable (BUS: 2x2xAWG22/7 9YH(ST)C11Y), so it mates directly with standard M12 PROFIBUS nodes without an adapter. Rated for 2 million bending cycles — the molded strain relief and 0.34 mm² conductor cross-section hold up in continuous-flex drag-chain applications, not just static tray routing.
