What it is and where it fits
The Siemens 6GT2891-0AH20-1AA0 is a 2-meter supply cable with a UK connector, purpose-built for the SIMATIC RF600 wide-range power supply. It's the plug-in link between the RF600 reader's power input and the mains — a field-replaceable cable, not a permanent gland connection. Rated IP65, so the connector end withstands washdown and dust ingress typical on a conveyor line or in a logistics center where RF600 readers are mounted near the action. That IP65 rating means the cable assembly can be swapped without pulling the reader enclosure apart.
What the IP65 rating means for deployment
IP65 on a cable connector means the mated connection is dust-tight and protected against low-pressure water jets from any direction. On an RF600 reader mounted at a gantry or on a conveyor frame, that covers the typical splash and dust exposure without needing a secondary enclosure around the power entry.
