Siemens 6GT2891-4UH20 SIMATIC RF1000 Connecting Cable RS232 M12/PicoBlade 2m RFID Cable
Siemens SIMATIC RF1000 connecting cable, RS232, M12/PicoBlade, 2 m; links RF1040R/RF1070R readers to RF166C, RF170C or RF18xC/CI modules.
Description
About the Connecting cable RS232, M12 / PicoBlade
About the Connecting cable RS232, M12 / PicoBlade
The Siemens 6GT2891-4UH20 is a pre-assembled SIMATIC RF1000 connecting cable with RS232 signaling, M12 (8-pole) on one end and a 5-pole PicoBlade connector on the other, in a 2 m length. It links an RF1040R or RF1070R reader to an RF166C, RF170C or RF18xC/CI communication module. The 4-core shielded design carries a 300 V maximum operating voltage and a 69 mm minimum bend radius.
Selection Notes
At 2 m, this is the fixed connecting cable between the reader head and its communication module in a cabinet-mounted RF1000 setup, not an extension run. The M12 (8-pole) end pairs with the reader; the 5-pole PicoBlade end plugs directly into RF166C, RF170C or RF18xC/CI, so check the module's connector type before ordering, since other RF1000 accessory cables in the range use different connector combinations. The 69 mm minimum bend radius sets the smallest loop the cable can take inside a cabinet.
