Product Description
A 5-meter M12 straight-plug to straight-socket cable built for SIMATIC RF systems and IO-Link device connections. The 4/8-pole configuration supports both standard 4-pole sensor wiring and higher-density 8-pole signal routing—reducing the need for multiple cable variants in mixed installations.
Which SIMATIC devices use this cable?
The M12 straight-to-straight configuration connects IO-Link masters to IO-Link devices, or extends existing M12 cable runs in SIMATIC RF200/RF300/RF600 reader installations. Verify the pole count at both ends—8-pole devices require all 8 conductors; 4-pole sensors use the inner 4 pins only.
What makes the PUR jacket the right choice?
Polyurethane jackets resist mineral oil, grease, and UV exposure—critical for machine-tool and outdoor-cabinet environments. PUR also handles continuous flexing better than PVC in cable carriers, with a typical bend radius of 8× the cable outer diameter under dynamic load.
Frequently Asked Questions
Can I use this with a 24VDC sensor?
Yes. The cable is rated for up to 30V, which covers all standard 24VDC industrial sensor and actuator circuits.
Is the cable shielded?
SIMATIC RF connecting cables include braided shield where required for signal integrity. Confirm shielding requirements against your specific reader or IO-Link master documentation.
