Description
Product Introduction
The Siemens 6GT2800-5DA00 (SIMATIC RF620R) is a compact, high-performance UHF RFID reader designed for automated material tracking in factory automation and logistics networks. Industrial engineers integrate this transceiver directly into conveyer systems, pallet tracking stations, and assembly lines to capture tag data on moving workpieces in real time.
Operating within the ETSI frequency band (865-868 MHz), the RF620R features an integrated antenna, eliminating the need for external coaxial cables and separate antenna mounting in space-constrained installations. In our field experience, replacing a damaged reader with this exact model restores precise long-range tag identification without re-architecting your existing PROFIBUS, PROFINET, or Ethernet/IP interface modules.

Application Scenarios & The “Trench” Experience
An automotive body-in-white transfer line suffered intermittent tracking faults when the primary RFID reader at station 40 failed to read pallet tags arriving at the welding cell. The fault brought the entire indexing conveyor to a dead stop, threatening expensive bottleneck delays across the body shop.
- Automotive Manufacturing – Skid & Pallet Tracking – Identifies vehicle chassis carriers entering robot assembly cells.
- Warehouse Logistics – Automated Tote Identification – Reads passive UHF tags on moving totes along high-speed sortation conveyors.
- Food & Beverage – Washdown Packaging Lines – Mounts directly in wet processing areas thanks to its rugged IP67 enclosure.
The shift technician swapped out the damaged reader for a pre-tested 6GT2800-5DA00 surplus unit. Utilizing the existing M12 connector harness linked to an ASM 456 interface module, the new reader powered up, locked onto the incoming transponders, and brought the assembly line back online inside 15 minutes.

Transparency SOP: Quality Assurance & Testing
We do not just ship boxes; we test them on actual Siemens SIMATIC RFID communication benches. Every 6GT2800-5DA00 undergoes the following verification process:
- Inbound Visual Inspection: Checking the aluminum housing, plastics, M12 pin connectors, and mounting threads for physical damage, metal shavings, or seal degradation.
- Power Rail & LED Handshake: Connecting 24VDC loop power to verify onboard status LEDs (Power, Transponder, Error) initiate clean internal diagnostics.
- RF Read/Write Field Stress Test: Running continuous read/write cycles against multiple EPC Class 1 Gen 2 transponders at varying distances and orientations to confirm antenna signal strength.
- Comm Module Interface Check: Validating data frame transmission back to a Siemens S7-1500 PLC via an RF communication interface module (e.g., RF180C / ASM456).
- ESD Cleaning & Protective Packaging: Cleaning connector faces, applying protective caps, and sealing the unit inside anti-static wrap with high-density shipping foam.
The Veteran’s Tech Trap Guide (Crucial Value-Add)
- ⚠️ Verify Regional Frequency Range: The 6GT2800-5DA00 is the ETSI version (865-868 MHz). If your plant is located in an FCC region (e.g., North America requiring 902-928 MHz), this unit will not operate on standard local frequencies or may violate local spectrum regulations. Check your regional part number requirements before ordering!
- ❗ Mind Tag Polarization & Metals: While the integrated antenna is circularly polarized, mounting this reader directly onto unshielded, heavy steel beams without isolation brackets can detune the RF field. Keep a 50mm clearance or use non-metallic spacers to prevent dead zones.
- ⚠️ Cable Length Matters: When connecting the M12 cable to your communication module (RF120C, RF180C, or ASM modules), do not exceed the recommended cable length specification. Signal degradation over long cable runs causes intermittent dropouts that look like internal reader faults.
Frequently Asked Questions (FAQ for Conversion)
Q: Does the 6GT2800-5DA00 require an external antenna?
A: No. The RF620R model features an internal, integrated circularly polarized antenna, making it a compact single-box solution for medium-range UHF applications.
Q: Can I connect this reader directly to a standard PROFINET network?
A: No, the reader connects via dedicated interface cables to a SIMATIC RFID communication module (such as the RF180C, RF120C, or ASM 456), which then bridges the data to PROFINET or PROFIBUS.
Q: What is the typical read range of the 6GT2800-5DA00?
A: Under optimal conditions with standard industrial UHF tags, the read range is up to 2 meters. Actual range depends on tag size, placement on the target, and surrounding metal structures.
Q: Is this unit IP-rated for outdoor or wet environments?
A: Yes, it features an IP67 enclosure rating, protecting it against heavy dust ingress and water exposure during equipment washdown.
Q: What warranty do you offer on this surplus RFID reader?
A: We provide a full 12-month replacement warranty on all new surplus and rig-tested 6GT2800-5DA00 units.
