A 10-meter M12 extension cable with straight connectors at both ends, built on TPE-U jacket technology for IO-Link master-to-device connections and SIMATIC RF reader installations. The male-to-female configuration extends an existing M12 cable run or connects a device directly when the master port is 10 meters away.

Why TPE-U instead of standard PUR?

TPE-U (thermoplastic polyurethane ether) offers the same oil, grease, and UV resistance as PUR but with measurably better abrasion resistance and flexibility at low temperatures. In cable carriers with millions of flex cycles, TPE-U jackets show less surface wear than equivalent PUR constructions. The trade-off is slightly higher cost—justified when the cable runs through moving machine elements.

How does the 4-pole pinout work for IO-Link?

IO-Link uses M12 A-coded 4-pole connectors. Pin 1 carries 24V, pin 3 is 0V, and pin 4 is the C/Q switching/communication line. Pin 2 can carry an additional digital input or output depending on the IO-Link master configuration. Always verify the master's port pinout before connecting devices that use pin 2.
