Description
Product Introduction & Engineering Value
RFID systems in production environments are usually installed because manual identification has already reached its limit. The Siemens 6GT2001-0AA00 MOBY I SLG 41 provides reliable contactless identification by reading and writing data stored in MOBY I identification tags.
This unit was widely used in Siemens automation environments for material tracking, assembly identification, and production logistics. Although it is a legacy MOBY I component, many plants continue operating it because the surrounding automation equipment remains functional and replacement requires system-level planning.

Field Application & The “Trench” Experience
A European automotive supplier running an older Siemens S5-based assembly line began seeing intermittent identification failures at several workstation points. Operators reported that carriers occasionally stopped because the system could not confirm the correct product information.
The engineering team first replaced several identification tags, assuming the problem was caused by damaged MDS units. The failures continued. During deeper troubleshooting, technicians found that one aging SLG 41 read/write head had unstable communication behavior caused by internal degradation.
Installing a tested Siemens 6GT2001-0AA00 restored reliable tag communication without modifying the PLC program or replacing the entire RFID system.
Common application scenarios include:
- Automotive assembly carrier identification
- Machine tool pallet tracking systems
- Production line workpiece routing using MOBY I tags
- Material handling stations requiring automatic identification

Transparency SOP: QA & Testing
For legacy RFID components, functional testing matters more than appearance.
Verification procedure:
1. Product Identification
- Confirm Siemens label.
- Verify exact article number: 6GT2001-0AA00.
- Check SLG 41 marking.
2. Physical Inspection
- Inspect housing condition.
- Check connector integrity.
- Verify IP65 sealing condition.
- Look for moisture or impact damage.
3. RFID Functional Test
- Apply 24 VDC power.
- Verify communication with compatible MOBY I interface equipment.
- Perform read/write test with supported MDS tags.
- Confirm stable operating distance.
4. Documentation
- Record serial number.
- Document test results.
- Classify inventory condition:
- New Surplus
- Refurbished
- Tested Used
The Veteran’s Tech Trap Guide
⚠️ Trap #1: Assuming Any Siemens RFID Head Is a Replacement
The MOBY family contains multiple RFID generations.
PRO TIP: Verify:
- RFID family compatibility
- MDS tag type
- Communication module type
- PLC interface architecture
A newer SIMATIC RF component is not automatically a direct replacement for MOBY I equipment.
⚠️ Trap #2: Ignoring Read Distance Requirements
The SLG 41 has a maximum operating distance of approximately 25 mm depending on the MDS.
Incorrect mechanical mounting can cause:
- Missed reads
- Intermittent identification
- Reduced production reliability
⚠️ Trap #3: Forgetting Legacy Lifecycle Status
The 6GT2001-0AA00 has reached the end of its product lifecycle and has been discontinued by Siemens.
For plants still operating MOBY I systems:
- Maintain tested spare readers
- Document installed RFID configurations
- Evaluate migration timing before emergency replacement is required
Dynamic FAQ
Q1. What is the Siemens 6GT2001-0AA00 used for?
The Siemens 6GT2001-0AA00 is a MOBY I SLG 41 RFID read/write device used for contactless identification and data exchange with compatible MOBY I data memory tags.
Q2. What is the maximum read/write distance of 6GT2001-0AA00?
The maximum operating distance is approximately 25 mm, depending on the connected MDS identification tag.
Q3. Is the 6GT2001-0AA00 still a current Siemens product?
No. Siemens documentation indicates that this MOBY I component has reached the end of its lifecycle and has been discontinued.
Q4. Can the 6GT2001-0AA00 be replaced by a newer SIMATIC RF reader?
Not directly in every installation. Replacement requires checking:
- Existing PLC interface
- Communication module
- Tag technology
- Mechanical mounting
- Software compatibility
Q5. What should buyers verify when purchasing New Surplus 6GT2001-0AA00?
Recommended checks:
- Original Siemens marking
- SLG 41 model confirmation
- Housing and connector condition
- RFID read/write test results
- Storage history
- Warranty terms
Q6. Is refurbished 6GT2001-0AA00 suitable for plant spare inventory?
Yes, if the unit has passed RFID communication testing and physical inspection. For legacy production systems, tested refurbished RFID heads are often maintained as emergency replacement inventory.
