​1.Product Overview​

The ​Allen-Bradley 1794-1J2 Terminal Housing​ serves as a rugged interface enclosure for Rockwell Automation’s ​FLEX I/O™ 1794-TB3/B Series​ terminal bases. Designed to protect wiring connections in harsh industrial environments, this injection-molded thermoplastic housing achieves ​NEMA 4X/13​ ratings (–20°C to +70°C) with UV resistance. Its ​screw-sealed cable entries​ (conduit not required) and ​clear flip-open cover​ enable quick visual inspections without disassembly. Supporting vertical/horizontal DIN rail mounting (EN 60715), the unit integrates anti-vibration locking tabs to prevent accidental dislodging. Compatible with all 1794-TB3/B terminal bases, it simplifies field wiring for distributed I/O systems while providing essential dust/chemical protection.

2.​Critical Technical Specifications​

​Durability and compatibility metrics:

• ​Material: Polycarbonate-ABS blend (UL 94 V-0 flammability rating)
• ​Protection: IP66 dust/water jet, NEMA 4X corrosion/oil resistance
• ​Temperature Range: –20°C to +70°C (operational)
• ​Cable Capacity: Accepts Ø8–14mm cables through M20 gland holes
• ​Impact Resistance: IK08 (5J impact protection per IEC 62262)
• ​Mounting: Top-hat DIN rail (35mm) with tool-free snap lock
• ​Sealing Force: 0.6–1.2 N·m torque for cover seals
• ​EMI Shielding: Metal clip option for 1794-TBNF noise-prone environments

3.​Targeted Applications​

​Harsh-environment wiring protection:

• ​Food & Beverage: Washdown zones for filler/capper I/O stations (FDA-compliant)
• ​Automotive: Robotic welding cell terminal protection against spatter/debris
• ​Chemical Processing: Acid-wash areas with airborne corrosives
• ​Material Handling: Conveyor junction boxes exposed to dust/oil mist
• ​Mining: Crushing plant I/O enclosures (MSHA 30 CFR Part 18)
• ​Water Treatment: Outdoor pump station termination boxes
• ​Packaging Machinery: Humidity control zones for label applicators

​4.Competitive Advantages​

​Installation and maintenance innovations:

• ​Time Savings: 60% faster wiring access versus screw-sealed housings
• ​Vibration Tolerance: Patent-pending ​ShockLock™ rail tabs​ withstand 10g vibrations
• ​Corrosion Defense: Salt spray resistance exceeds 1,000 hours (ASTM B117)
• ​Wiring Clarity: ​Magnifying cover​ amplifies wire labels by 150%
• ​Safety Compliance: Transparent cover enables arc-flash inspections per NFPA 70E
• ​Space Efficiency: 30% slimmer profile than metal alternatives
• ​TCO Reduction: Eliminates $300+ per year conduit maintenance

5.​Functional Capabilities​

​Advanced environmental protection:

• ​Dual-Purpose Design: Accepts standard or shielded cables via adaptable glands
• ​Tool-Less Entry: Spring-loaded cable glands clamp without torque tools
• ​Grounding Integrity: Integrated ​zinc-plated grounding bar​ (10–4 AWG)
• ​Thermal Management: Ventilation slots prevent condensation (>95% RH)
• ​Hazardous Area Compliance: Converts standard terminals to ​NEC 500 Class I Div 2​
• ​Color Coding: Optional neon-yellow covers for safety circuit identification
• ​Modular Expansion: Stackable housings for multi-tier terminal bases
