The 6ES7194-2MH50-1AC0 is a 5-meter 24VDC power cable with a straight M8 socket on one end and open conductors on the other. It feeds ET 200AL modules from a nearby terminal block — short enough to avoid excess cable in the duct, long enough to route cleanly from the 24VDC distribution strip to the module's gray power port.

Five meters vs. ten — when does the shorter cable win?

Five meters is the right length when the power distribution terminal block lives in the same cabinet section or on the same machine frame member as the ET 200AL station. It avoids coiling 5 extra meters of cable in the trunking — excess cable traps heat, clutters the duct, and creates an unintentional loop antenna for EMI coupling into nearby signal wiring. If the power feed is on the opposite side of the cabinet or in a separate enclosure, step up to the 10-meter variant (6ES7194-2MN10-1AC0). The conductor gauge and electrical characteristics are identical — the choice is purely how much cable you need and how much slack you are willing to manage.

Socket-to-open-end: when the destination is not an M8 port

The molded M8 socket plugs into the ET 200AL module's gray power port. The other end is stripped and tinned conductors — land them directly under the screw terminals of the 24VDC distribution block. No need to buy a double-ended cable and cut off a plug. The open end also lets you trim to exact length: if the terminal block is 4 meters away, shorten the open end and keep the factory-sealed M8 socket intact.

Frequently Asked Questions

What is the difference between this cable and the green open-end variant?

This cable (gray, 6ES7194-2MH50-1AC0) carries 24VDC power — unshielded 4×0.50mm² conductors. The green open-end variant (6ES7194-2MN10-0AC0) carries PROFINET data — shielded 2×2×0.5/1.0mm twisted pairs. Match jacket color to the ET 200AL port color. Plugging a power cable into a bus port or vice versa causes equipment damage.

Can this cable run in a cable carrier?

Yes. The PUR jacket is rated for 2,000,000 flex cycles at a 51mm continuous bend radius and 5m/s travel speed. The minimum single-bend radius is 26mm — tighter bends during installation permanently deform the conductors.
