Product details

Bus cable — M12 angled, 3 m, 2-wire

The 3RK1902-1NB30 is a pre-terminated M12 bus cable assembly with an angled plug on one end and an angled socket on the other, populated on both sides. It carries two electrical cores (red/green insulation) in a polyurethane sheath with a tinned copper shielding braid. Rated 4 A per pin maximum at 60 V AC/DC, this cable handles the bus power and signal for Siemens AS-Interface or similar 2-wire fieldbus segments. The M12 x 1 threaded interlock keeps the connection secure under vibration. With 5,000,000 bending cycles and a pollution degree 3 rating, it's built for continuous-flex applications in industrial environments where conductive dust or moisture is present.

Compliance and approvals

UL, CSA, and IEC approved — the cable carries the marks for North American and international acceptance. RoHS conformity is confirmed. CCC, C-Tick, and cUL are all marked 'No' — this variant is not certified for China, Australia/New Zealand, or Canadian UL. Verify local market requirements before specifying.

Sourcing and lifecycle

This is a fixed-length 3 m assembly with angled outlets on both ends. It is not a field-terminable cable — the connector ends are molded with integral strain relief. Order the exact length needed; no field cutting or re-termination.
