Siemens 6ES7194-2MH20-0AC0 is a pre-assembled M8 bus cable for ET-CONNECTION nodes like SIMATIC ET 200AL in IP65/67 enclosures. Shielded construction with overlapping aluminum-clad foil and tin-plated copper braid — keeps noise off the 4-wire signal run. Halogen-free and silicone-free sheath, rated for continuous flex at 1 million bending cycles (bending radius 100 mm, speed 4 m/s, acceleration 4 m/s²). That makes it a valid pick for drag-chain routing on moving machine sections.
What the ratings mean for fit
Temperature range spans -40 to 80 °C — covers cold storage lines and washdown zones near ovens. The -30 °C assembly minimum means you can terminate in a cold warehouse, though handling at the extreme low end is snappier. Single-bend radius is 20 mm, multiple-bend radius 40 mm. The continuous flex radius is 100 mm — nearly the diameter of a coffee can. If you cram it tighter, expect braid fatigue before the 1M cycle count. Sheath color is green, silicone-free and halogen-free. PUR jacketing holds up against oils and abrasion common in automotive and food plants.
Lifecycle and sourcing
Active according to Siemens lifecycle data — no NRND or end-of-life flags. This is a standard-parts cable, widely stocked. Quoted to order against an RFQ; expect standard lead times. Keep one on the shelf as a spare if your line uses ET 200AL nodes.
