What this cable is and where it fits
The Siemens 3RK1902-4HC01-5AA0 is a pre-assembled M12 control cable, angled on one side and open on the other, with a 10 m PUR sheath and five 0.34 mm² cores. It's A-coded, 5-pole, and rated for 4 A per pin at up to 125 V DC. The IP67 protection class means the connector end handles washdown environments — common on food-and-bev lines or anywhere you hose down a panel face.
Key ratings and what they mean for fit
The 4 A ampacity per pin is the current limit per conductor — sum your loads across the five pins and stay under that. The 125 V DC operating voltage covers most 24 V DC sensor/actuator loops with headroom, but if you're running 48 V or 60 V DC it's fine; just don't push past the ceiling. Temperature range is -25 °C to 80 °C, so it's fine in unheated cabinets or near hot machinery, but not for direct oven-side placement.
Approvals and compliance
Carries UL, CSA, and IEC approvals, so it's accepted in North American and international panels without a separate agency review. The PUR sheath is oil- and grease-resistant per the conditional ratings — check your specific fluid exposure against the application notes, but it's built for industrial environments.
Physical integration notes
The M12 x 1 thread with A-coding mates to standard M12 sockets on sensors, actuators, or I/O blocks. The angled outlet keeps the cable low-profile against the panel face — useful when you're tight on clearance. The 5 mm cable outer diameter and 0.34 mm² conductors are typical for signal-level wiring; don't use this for power feeds.
