Siemens 6GT2891-6UH20 SIMATIC RF1000 Connecting Cable RS232 Sub-D/PicoBlade 2m RFID Cable
Siemens SIMATIC RF1000 connecting cable, RS232, Sub-D/PicoBlade, 2 m; links RF1040R/RF1070R readers to the RF120C module.
Description
About the Connecting cable RS232, Sub-D / PicoBlade
About the Connecting cable RS232, Sub-D / PicoBlade
The Siemens 6GT2891-6UH20 is a pre-assembled SIMATIC RF1000 connecting cable with RS232 signaling, a 9-pole Sub-D connector 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 the RF120C 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 the RF120C communication module, not an extension run. The Sub-D (9-pole, 45 degree) end sets it apart from the M12-ended variant used for other RF1000 modules, so match the connector type on the module before ordering. The 69 mm minimum bend radius sets the smallest loop the cable can take inside a cabinet.
