The STAHL ETA-436-A-TX-R2-TFT-16GB-PES is a rugged, explosion-proof industrial tablet computer designed for safe operation in hazardous areas classified as Zone 2 (gas) and Zone 22 (dust) under the ATEX and IECEx directives. Manufactured by STAHL, a global leader in explosion protection technology, this device combines high-performance computing with intrinsic safety, enabling operators to run SCADA, MES, asset management, or remote diagnostics directly at the point of need—without compromising safety.
Housed in a sealed, non-sparking aluminum-magnesium alloy enclosure with IP66/IP67 ingress protection, the ETA-436 features a 10.1-inch high-brightness TFT display with projected capacitive multi-touch (PCAP) that works reliably with gloves or in wet conditions. The “PES” suffix indicates it is configured for general-purpose industrial use with enhanced environmental sealing and EMI shielding. With 16GB solid-state storage, an energy-efficient Intel processor (typically Atom® or Celeron® class), and fanless passive cooling, the unit operates silently and reliably in ambient temperatures from -20°C to +60°C.
The “R2” designation often refers to a specific hardware revision or regional compliance variant, while “TX” denotes the inclusion of advanced touchscreen capabilities. Designed for seamless integration into process automation systems, the ETA-436 supports standard industrial protocols via Ethernet and optional wireless modules (Wi-Fi 5 / Bluetooth 4.2, where permitted by local hazardous area regulations).

✅ Main Features and Advantages
Certified Safety for Hazardous Environments: Unlike standard tablets retrofitted with enclosures, the ETA-436 is engineered from the ground up for explosive atmospheres. Its Ex nA (non-sparking) and Ex tc (powder ignition protection) certifications ensure no internal sparks or hot surfaces can ignite surrounding gases or dust—critical in chemical plants, refineries, and paint booths.
Robust All-in-One Design: The fully sealed, fanless construction eliminates moving parts and prevents ingress of corrosive vapors, salt spray, or cleaning agents. The anti-reflective, high-luminance screen ensures readability even in direct sunlight—ideal for outdoor skids or offshore platforms.
Industrial Software Ready: Pre-loaded with Windows 10 IoT Enterprise, the ETA-436 supports mainstream SCADA (e.g., WinCC, Ignition), historian clients, and remote desktop tools (TeamViewer, VNC). Its standard interfaces simplify connection to PLCs, barcode scanners, or RFID readers via docking stations.
Future-Proof Serviceability: Despite its sealed design, the ETA-436 allows firmware updates and OS recovery via USB or network. STAHL provides long-term availability (10+ years) and lifecycle support—essential for capital-intensive process facilities.
