It's a 4-core unshielded cable with an M12 female 4-pin straight connector on one end and an open end with labeled wire end sleeves on the other, giving you a fixed 10 m run for wiring into a terminal block or control cabinet. The 30 V maximum rating is the voltage class for the cable and its insulation — it's sized for the 24 VDC supply typical of IO-Link systems, not for higher-voltage sensor buses. The PVC wire insulation and black PVC sheath handle the standard industrial environment, and the flame resistance carries AWM STYLE 21317 VW-1 for the US and AWM I/II A/B FT-1 for Canada, so it passes the vertical flame test required inside panels and cable trays. ## Cable construction and electrical characteristics The cable designation is LiY-11Y 4xAWG 22/19 — four 22 AWG stranded conductors (19 strands each), unshielded. The individual wire insulation colors are brown, white, blue, and black, which maps to standard IO-Link pin assignments (pin 1 brown = 24 V, pin 3 blue = GND, pin 4 black = C/Q, pin 2 white = optional). Loop resistance per length is 108 mΩ/m, so for the full 10 m cable you're looking at roughly 1.08 Ω per conductor loop — negligible for the 200-300 mA typical IO-Link device draw, but worth checking if you're running a high-current actuator off the same cable. Insulation resistance coefficient is 20 GΩ·m, which is solid for signal integrity in industrial environments. Minimum bend radius with single bend is 34.4 mm, with multiple bends 64.5 mm — tight enough for cable duct routing but not for sharp panel corners. The symmetrical tolerance on the outer diameter is 0.15 mm, so the cable fits standard M12 cord grips without issue. ## Environmental range and lifecycle Installation temperature matches the operating range — don't try to lay it below -5 °C or the PVC stiffens and risks cracking the insulation. Lifecycle status is Active, meaning Siemens still lists it as a current catalog item. No NRND or phase-out flags here — it's a standard IO-Link cable in the SIMATIC RF family, so you can spec it into a BOM without worrying about a last-time-buy window. The cable is not halogen-free, so if your project requires low-smoke zero-halogen materials for enclosed spaces, this isn't the one.","metaTitle":"Siemens 6GT2891-4LN10 SIMATIC RF IO-Link cable, 10 m, 30 V","metaDescription":"Siemens 6GT2891-4LN10 SIMATIC RF IO-Link connecting cable, 4-core, M12 female to open end, 10 m, 30 V, PVC insulation, flame resistant.
