The Siemens 6ES7194-2LN15-1AC0 is a pre-assembled flexible power cable for the ET 200AL I/O system, terminated at one end with an M8 4-pole female connector. It supplies 24 V DC to remote modules and is rated for continuous flexing in cable carriers, with a bending radius of 52 mm and 2.5 million bending cycles. Silicone-free construction suits paint shops and clean environments.
What the ratings mean for fit
The temperature range of -40 to 80 °C covers cold storage, outdoor enclosures, and machinery near heat sources, but the cable’s ambient temperature during assembly is limited to -30 °C minimum, so avoid pulling in deep freeze conditions. IP65/67 means the connector-end is dust-tight and protected against temporary immersion—good for washdown zones. For cable carrier layouts, the specified 52 mm bend radius and 2.5 million cycles are the fatigue limit; a design with shorter radius or higher acceleration will reduce service life. The 4-core cable uses Li9Y 0.50 mm² conductors, with a 5.2 mm outer diameter of PVC sheath, fitting standard M8 connectors. The gray sheath color matches typical ET 200AL cabling runs.
