Core Technical Specifications and Deployment Scope
The Cisco Catalyst C9105AXWT-S is a ruggedized Wi-Fi 6E (802.11ax) access point engineered for hazardous industrial environments requiring intrinsic safety. Key differentiators include:
- IECEx/ATEX Zone 1 Certification: Operates safely in explosive gas/dust atmospheres (e.g., methane, coal dust)
- 6 GHz Ultra-Wideband Support: Utilizes 160 MHz channels in 5925-7125 MHz bands for low-latency industrial IoT
- Stainless Steel Enclosure: IP69K-rated against high-pressure steam cleaning and chemical splashes
Designed for pharmaceutical cleanrooms, underground mining, and ammonia refrigeration facilities, it delivers 4.3 Gbps aggregate throughput while maintaining ≤1 ms jitter for PROFINET/Modbus TCP industrial protocols.
Performance Comparison: C9105AXWT-S vs. C9105AXWT-D
| C9105AXWT-S | C9105AXWT-D | |
|---|---|---|
| Hazardous Certification | Zone 1 (IECEx) | Zone 2 (ATEX) |
| Frequency Bands | 2.4/5/6 GHz | 2.4/5 GHz |
| Max EIRP | 24 dBm (6 GHz) | 33 dBm (5 GHz) |
| Enclosure Material | 316L Stainless Steel | Cast Aluminum |
| Conduit Ports | 2x M20 threaded | 1x NEMA 4X |
The C9105AXWT-S trades peak transmit power for intrinsic safety in Zone 1 areas, leveraging 6 GHz’s cleaner spectrum for deterministic wireless control.
Overlooked Safety and Configuration Features
Three critical but underdocumented capabilities:
- Galvanic Isolation: 2500V AC isolation between RF and power circuits to prevent ground loops in substations
- Non-Sparking Antennas: Fiberglass-reinforced radomes with <0.02 mJ ignition energy threshold
- UL 844 Compliance: Certified for Class I Div 1 environments with Group A (acetylene) gas protection
Procurement Best Practices via Itmall.sale
When sourcing the C9105AXWT-S, verify:
- Explosion Protection Documentation: IECEx System Certificate and Entity Parameters for installation audits
- Cisco Industrial IoT License: Enables ISA-95 hierarchy mapping for OT/IT convergence
- Conduit Sealing Kits: Optional epoxy-filled cable glands meeting NEC 500.8 standards
Solving Zone 1 Wireless Challenges
The C9105AXWT-S addresses two life-critical industrial needs:
- Deterministic Spectrum Sharing: Time-Sensitive Networking (TSN) over 6 GHz coordinates robotic arms and AGVs without interference
- Gas Group Flexibility: Field-upgradable firmware supports Group IIC (hydrogen) to Group IIB (ethylene) without hardware swaps
In a recent deployment at a lithium battery plant, the C9105AXWT-S’s 6 GHz band eliminated RF interference from high-voltage arcing—a persistent issue with 5 GHz models. While its stainless steel build doubles the weight of aluminum APs, the corrosion-resistant passive cooling ensures 10+ year lifespans in chlorine-rich environments. Always conduct a hazardous area classification audit and review NFPA 70 Article 501 compliance before commissioning.
