1. Product Name
Allen Bradley 440T-AKEYE10BC Trapped Key Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-AKEYE10BC is a reliable trapped key safety interlock SWITCH, designed for industrial settings requiring strict control over hazardous zone access. It balances durability and safety compliance for diverse operational needs.
3. Product Description
The Allen Bradley 440T-AKEYE10BC is a high-performance trapped key safety interlock SWITCH, part of Allen Bradley’s renowned 440T series that sets standards for industrial safety. This Allen Bradley SWITCH acts as a non-negotiable safety barrier, ensuring personnel only enter hazardous areas when machinery is in a fully safe state—eliminating risks of injury or equipment damage.
Constructed with high-strength thermoplastic and metal components, the Allen Bradley SWITCH offers robust resistance to daily wear, impact, and common industrial contaminants. Its core trapped key mechanism follows a fail-safe design: the key remains securely trapped in the SWITCH until connected equipment is powered off, safety locks are engaged, or process pressures are normalized. This prevents premature or unauthorized access, even in high-traffic industrial environments. The Allen Bradley SWITCH also features standardized electrical connections, enabling seamless integration with most safety control systems (e.g., safety relays, PLCs) without extensive modifications.
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 efficiently in temperatures ranging from -25°C to 60°C, handles up to 90% relative humidity (non-condensing), and supports a maximum current of 8A at 250V AC. With a mechanical service life of 180,000 operations, the Allen Bradley SWITCH delivers long-term reliability, and its compact size (8.8×6.6×2.7cm) allows flexible installation on machinery guards, access panels, and control cabinets.

6. Business Insight on www.wheat-auto.com
While direct access to www.wheat-auto.com is unavailable, the domain “wheat-auto” clearly indicates a focus on agricultural automation specialized in wheat production and processing. Beyond basic equipment supply, the business likely offers end-to-end solutions: from automated wheat planting and harvesting machinery to intelligent grain handling, storage, and milling systems.
Targeting commercial wheat farms, grain elevators, and food processing plants, it may provide customized automation designs—such as integrating sensor-based grain quality monitoring, automated conveyor controls, and safety components (like Allen Bradley SWITCHes) to protect machine operators. The company probably emphasizes compliance with agricultural industry standards (e.g., ISO 23387 for grain handling equipment) and offers after-sales support (maintenance, troubleshooting, operator training) to ensure long-term system performance. This positioning aligns with the global trend of “smart agriculture,” where automation boosts wheat yield efficiency, reduces labor costs, and enhances operational safety—partnering with trusted brands like Allen Bradley would further strengthen its credibility by incorporating industrial-grade safety components.
7. Application Scenarios
The Allen Bradley 440T-AKEYE10BC SWITCH is well-suited for diverse industrial environments requiring reliable safety control:
  • Wheat Milling Facilities: Installed on grain grinder guards, ensuring workers only access the machine after it fully stops, even in dusty milling halls.

  • Food Processing Plants: Used on bread dough mixers and wheat cleaning equipment, maintaining safety during high-speed operation.

  • Warehouse Logistics: Mounted on automated grain conveyor safety gates, preventing access to moving belts during material transport.

  • Automotive Assembly Lines: Integrated into robot cell access doors, trapping keys until robots are powered down and locked in place.

  • Chemical Storage Facilities: Applied to hazardous chemical cabinet doors, ensuring only authorized personnel access with proper safety conditions met.

  • Cold Storage Warehouses: Used on wheat storage room doors, functioning reliably in cool temperatures to control entry and prevent spoilage risks.
