It carries 4 pins rated at 4A per pin maximum, with a 60V AC/DC voltage limit, so it's sized for signal and auxiliary power — not motor or main circuit loads. The cable is shielded (tinned copper braid) with a polyurethane jacket, rated for 2 million bending cycles, which suits it for drag-chain or moving-machine applications. The 4A per pin ampacity covers typical sensor/actuator bus loads (e.g., 24V DC auxiliary supply for a few I/O blocks). The 60V AC/DC maximum means it's not for 120V or 230V circuits. The 3m length is a fixed cable — no field-cut-to-length option. The angled M12 connectors (both ends) save space in tight junction boxes or where cable exit direction matters. The 0.34 mm² conductor cross-section and 100 Ω characteristic impedance at 100 MHz confirm it's a standard PROFIBUS cable variant.","metaTitle":"Siemens 3RK1902-2NB30 M12 Bus Cable, 3m, 4-Pin, 4A per Pin","metaDescription":"Siemens 3RK1902-2NB30 M12 angled bus cable, 3m, 4-pin, 4A per pin, 60V AC/DC, shielded, RoHS, IEC approved.
