Siemens 6GT2831-6CA60 SIMATIC RF1000 RF1040R USB/RS232 Reader 125 kHz/13.56 MHz RFID Reader

The Siemens 6GT2831-6CA60 is a SIMATIC RF1000 RF1040R dual-frequency access control reader with USB 2.0 and RS232 interfaces. It reads LF transponders (HiTag 1/2/S, EM41xx/45xx) at 125 kHz and HF transponders (ISO 14443 A/B, ISO 15693) at 13.56 MHz, with optional BLE at 2.4 GHz, and carries an IP65 front rating after cabinet installation.

Technical Specifications

Selection Notes

The RF1040R is the only USB/RS232 reader in the family that covers LF tags (HiTag, EM41xx) alongside the HF ISO 14443/15693 set, so it fits a mixed-badge migration where old LF cards are still in circulation. Choose the RF1060R or RF1070R instead when the site is HF-only, since dropping LF support is not a trade-off there; choose the PoE RF1140R when the reader needs to run over the network instead of a local USB/RS232 host.

Applications

Dual-band LF/HF reading in a single 90 x 62 x 23.5 mm housing lets one reader replace two single-band units during a legacy-card phase-out at doors and turnstiles.
