Siemens 6ES7194-2LH20-0AA0 SIMATIC ET 200AL Connecting Cable ET-Connection 4-Pole 2m Remote I/O Accessory

The Siemens 6ES7194-2LH20-0AA0 is a shielded ET-Connection bus cable that links SIMATIC ET 200AL nodes over a 2 m run. Preassembled at both ends with straight 4-pin M8 plugs, it carries the two shielded data cores between stations at the IP65/67 protection rating the ET 200AL line uses. The 100 mm continuous bending radius suits fixed cable-tray routing across a wider station spacing.

Selection Notes

Pick the straight-connector version when the two ET-CONNECTION nodes sit in line with enough clearance behind each M8 port for a 180-degree cable exit; it keeps the run flush along the mounting rail. The shielded twisted construction (2Y(ST)CY) protects the bus signal over the full 2 m run, and the 100 mm continuous bending radius sets the minimum loop size when routing around a corner. Where enclosure space forces the connector to exit sideways instead, the angled variant in this line avoids straining the M8 boot.
