ET 200AL power connection — preassembled, rated for continuous flex
This is the Siemens 6ES7194-2LH50-1AB0, a 5-meter power cable preassembled at both ends with a 4-pin M8 male connector (angled) and a 4-pin M8 female connector (angled). It is designed specifically for supplying 24 V DC power to ET 200AL distributed I/O modules. The cable carries four cores (4 Li9Y 0.50 mm² Y) with a gray PVC sheath and a 5.2 mm outer diameter. Each core uses PP insulation over a 0.8 mm inner conductor, with core insulation at 1.46 mm diameter. Rated IP65/67 when mated, this cable handles washdown environments. The silicone-free construction matters for paint shops and coating lines where silicone contamination causes adhesion failures.
Cable carrier rating — 2.5 million bending cycles at 52 mm radius
This cable is certified for continuous flex applications: 2,500,000 bending cycles at a 52 mm bending radius, 3 m/s travel speed, and 10 m/s² acceleration. That places it in the range for dynamic cable carrier installations on moving machine axes. For single-bend installations (non-moving), the minimum permissible bending radius drops to 26 mm. The continuous flex radius is 52 mm, matching the cable carrier spec. The -30 °C minimum assembly temperature allows cold-weather installation without embrittlement.
Active lifecycle — no obsolescence concern
The lifecycle status is listed as current/active. This is a standard production cable from Siemens, not a legacy or phase-out line. The 90-degree cable outlet on both connectors keeps the cable routed flat against the mounting surface — useful in tight junction boxes or when the cable exits parallel to the module face.
