The 4-pin, 4A-per-contact rating at 60V AC/DC covers most 24V DC discrete I/O and low-power analog signals without derating concerns. ## Cable construction that survives the cabinet-to-machine run Polyurethane outer sheath and thermoplastic polyurethane enclosure — the PUR jacket resists mineral oil, grease, and water exposure (though application-specific verification is advised per the conditional ratings). The tinned copper braid shield handles EMI from nearby VFD or motor cables; the 100Ω characteristic impedance at 100 MHz matches Profibus and similar fieldbus signal requirements. Molded strain relief and 2 million bending cycles mean this cable handles continuous flexing on a robot arm or linear axis without premature jacket cracking or conductor fatigue. The M12 x 1 thread lock keeps the connector mated under vibration to IEC 61076-2-101. ## Approvals and compliance — what the panel inspector checks UL, CSA, and IEC approvals are confirmed — the cable meets the major North American and international standards for industrial control wiring. RoHS conformity (Yes) covers EU material restrictions; CCC and C-Tick are marked No, so this cable is not pre-certified for China or Australian EMC markets without separate local assessment.","metaTitle":"Siemens 3RK1902-2HB30 M12 Bus Cable, 3m, 4-Pin, 4A","metaDescription":"Siemens 3RK1902-2HB30 M12 angled bus cable, 3m, 4-pin, 4A per pin, 60V AC/DC.
