The 6GT2391-0AE60 is a 0.6-meter pre-assembled coaxial antenna cable with one straight and one angled M8 plug, built with 2YCC11Y coax and a black PUR jacket. At 60 centimeters, this is the shortest standard M8 antenna cable in the SIMATIC RF200/RF300 family—half the length of the next variant up (1-meter). It exists for one reason: the reader port and antenna port are nearly touching, and even a meter of cable would mean coiling excess behind the panel.

Why would anyone need a cable this short?

In a tightly packed control cabinet, a SIMATIC RF200/RF300 reader and its antenna are often mounted on the same DIN rail or on adjacent brackets—the ports might be 20 or 30 centimeters apart. A 3-meter cable leaves over two and a half meters of coax to manage. You coil it, zip-tie it, tuck it behind wire duct—and every coil is an inductor you did not ask for. At HF (13.56 MHz) the electrical impact of a small service loop is negligible, but the mechanical clutter is real. The 0.6-meter cable eliminates the excess entirely: connect, route directly, done.

How does this differ from the 1-meter and 3-meter M8 antenna cables?

All three share the same 2YCC11Y cable construction, 50Ω impedance, and mixed straight/angled M8 connector geometry. The only difference is length: 0.6 meters (6GT2391-0AE60), 1 meter (6GT2391-0AF10), and 3 meters (6GT2391-0AH30). Choose the shortest cable that reaches—no shorter, no longer. The straight plug goes into the port with more clearance; the angled plug goes into the tight side.
