Application fit and supply reality
The 6ES7194-2LN15-0AC0: Production status is active per Siemens, so this part is still in the current catalog. Verification tip: the cable sheath is green PVC, and the printed designation should match the reel exactly. Silicone-free but not halogen-free — relevant if routing through fire-critical cable trays.
Installation notes and design limits
The rated IP65/67 means the M8 connector end is sealed against dust and water ingress when properly tightened. Minimum bending radius: 20 mm for a single bend, 40 mm for multiple bends, and 100 mm for continuous flex. Outer diameter of the cable sheath is 5 mm — plan grommets and cord grips accordingly. Core insulation is PE, conductor 0.5 mm. The 180° cable outlet at the plug dictates orientation; account for that in layout to avoid strain on the connector. Counterfeit risk is low for a current-production Siemens cable, but I always check the braid weave density and foil overlap under a loupe. Real Siemens cable uses a tight braid with consistent pitch. If the cable feels stiff or the sheath color is off (should be a specific Siemens green), flag it. Storage temperature not listed — but the operating range gives confidence for most warehouse conditions.
Traceability and procurement posture
No obsolescence or last-time-buy notice on record. For BOM freeze or PCN watch, this part is stable. When ordering, confirm the date code on the reel matches the factory code — a mismatch is the first sign of a relabeled run. Siemens provides traceability via the 2Y(ST)CY designation and the lot number printed on the jacket. Keep the original packaging if possible; reels with mismatched labels are a known counterfeit vector.
