1. Product Name
Allen Bradley 440T-AKEYE10VL Trapped Key Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-AKEYE10VL is a chemical-resistant trapped key safety interlock SWITCH, engineered for industrial environments with exposure to corrosive substances, ensuring durable safety control.
3. Product Description
The Allen Bradley 440T-AKEYE10VL is a high-performance trapped key safety interlock SWITCH, part of Allen Bradley’s trusted 440T series designed to mitigate risks in chemically harsh industrial settings. This Allen Bradley SWITCH acts as a non-negotiable safety barrier, ensuring access to hazardous zones is only permitted when equipment is de-energized and chemical exposure risks are eliminated.
Constructed with a specialized chemical-resistant coating and reinforced polymer housing, the Allen Bradley SWITCH withstands contact with common industrial chemicals (e.g., cleaning agents, mild solvents) and prevents corrosion of internal components. Its core trapped key mechanism follows a fail-safe design: the key remains securely trapped in the SWITCH until connected systems meet safety criteria—such as chemical neutralization or equipment shutdown—eliminating accidental access caused by human error. The Allen Bradley SWITCH also features universal electrical terminals, enabling seamless integration with standard safety control systems (e.g., safety PLCs, emergency stop circuits) without custom 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 reliably in temperatures ranging from -30°C to 65°C, handles up to 90% relative humidity (non-condensing), and supports a maximum current of 10A at 250V AC. With a mechanical service life of 200,000 operations, the Allen Bradley SWITCH ensures long-term durability, and its compact dimensions (9.1×6.8×2.9cm) allow flexible installation on machinery guards, chemical storage cabinets, and control panels.

6. Business Insight on www.wheat-auto.com
While direct access to www.wheat-auto.com is unavailable, its domain “wheat-auto” confirms a focus on agricultural automation tailored to wheat production, processing, and storage. The business likely offers end-to-end solutions: from automated wheat planting/harvesting machinery to intelligent grain processing lines (cleaning, milling, chemical treatment for preservation) and outdoor storage systems.
Targeting commercial wheat farms, grain elevators, and food processors, it probably provides customized designs—such as integrating chemical treatment modules for wheat preservation and chemical-resistant safety components (like the Allen Bradley 440T-AKEYE10VL SWITCH) for equipment near corrosive agents. Compliance with agricultural standards (e.g., ISO 23387 for grain handling) and after-sales support (maintenance, operator training) are key to its offerings. This aligns with “smart agriculture” trends, where automation boosts wheat yield efficiency, cuts labor costs, and ensures safety in chemical-related processes. Partnering with Allen Bradley enhances credibility by incorporating industrial-grade, chemical-adaptable safety switches.
7. Application Scenarios
The Allen Bradley 440T-AKEYE10VL SWITCH is ideal for chemical-exposed and industrial environments requiring reliable safety control:

  • Wheat Preservation Zones: Installed on chemical storage cabinets for wheat preservatives, preventing unauthorized access to corrosive agents.

  • Food Processing Labs: Used on equipment for wheat quality testing (e.g., solvent-based analysis), withstanding mild chemical exposure.

  • Industrial Cleaning Areas: Mounted on wheat processing machine guards near chemical cleaners, resisting corrosive residues.

  • Chemical Manufacturing Plants: Applied to valve control panels for mild solvent lines, ensuring safe access after chemical isolation.

  • Agricultural Chemical Facilities: Integrated into wheat pesticide mixing equipment guards, preventing contact with corrosive pesticides.

  • Pharmaceutical-Grain Cross Settings: Used on machinery for wheat-based pharmaceutical ingredients, withstanding sanitizing chemicals.
