1. Product Name
Allen Bradley 440T-AKEYE10TL Trapped Key Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-AKEYE10TL is a weather-resistant trapped key safety interlock SWITCH, engineered for industrial environments with variable weather, high humidity, or frequent temperature fluctuations.
3. Product Description
The Allen Bradley 440T-AKEYE10TL is a high-performance trapped key safety interlock SWITCH, part of Allen Bradley’s industry-leading 440T series dedicated to hazard prevention in challenging industrial settings. This Allen Bradley SWITCH acts as a mandatory safety barrier, ensuring access to hazardous machinery or zones is only allowed when equipment is shut down, pressure is relieved, or other safety prerequisites are met.
Constructed with a dual-protection housing—combining anti-rust stainless steel and weather-sealed thermoplastic—the Allen Bradley SWITCH resists rain, snow, and high humidity, while blocking dust ingress to avoid internal component damage. Its core trapped key mechanism follows a fail-safe design: the key remains securely locked in the SWITCH until connected systems are fully de-energized, eliminating accidental access caused by operational oversight. The Allen Bradley SWITCH also features standardized electrical terminals, enabling seamless integration with common safety control systems (e.g., safety PLCs, emergency stop relays) 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 -35°C to 70°C, handles up to 95% relative humidity (non-condensing), and supports a maximum current of 10A at 250V AC. With a mechanical service life of 220,000 operations, the Allen Bradley SWITCH ensures long-term durability, and its compact dimensions (9.2×6.9×3.0cm) allow flexible installation on outdoor machinery guards, semi-exposed access doors, or control panels.

6. Business Insight on www.wheat-auto.com
While direct access to www.wheat-auto.com is unavailable, its domain “wheat-auto” clearly focuses on agricultural automation tailored to wheat production, processing, and storage. The business likely offers end-to-end solutions: from automated wheat harvesting machinery (e.g., sensor-equipped combines) to intelligent grain processing lines (cleaning, milling, drying) and outdoor storage yard control systems.
Targeting commercial wheat farms, grain elevators, and food processors, it probably provides customized designs—such as integrating moisture sensors for optimal wheat drying and weather-resistant safety components (like the Allen Bradley 440T-AKEYE10TL SWITCH) for semi-outdoor conveyor or silo systems. Compliance with agricultural standards (e.g., ISO 23387 for grain handling equipment) and after-sales support (maintenance, operator training) are key to its offerings. This aligns with global “smart agriculture” trends, where automation boosts wheat yield efficiency, cuts labor costs, and ensures safety in mixed indoor-outdoor operations. Partnering with Allen Bradley enhances its credibility by incorporating industrial-grade, weather-adaptable safety switches.
7. Application Scenarios
The Allen Bradley 440T-AKEYE10TL SWITCH is ideal for weather-exposed, high-humidity, or dusty industrial environments:

  • Outdoor Wheat Storage Yards: Installed on silo access doors, resisting rain and grain dust while controlling entry during loading/unloading.

  • Semi-Outdoor Conveyors: Used on wheat transport belt safety gates, withstanding variable weather to prevent access to moving parts.

  • High-Humidity Mills: Mounted on wheat cleaning machine guards, tolerating moisture to ensure safe maintenance access.

  • Cold-Storage Grain Facilities: Integrated into refrigerated warehouse doors, functioning reliably in -35°C conditions to control entry.

  • Outdoor Mining Sites: Applied to mineral conveyor guards, resisting rain and dust to protect workers in open-pit operations.

  • Food Processing Wash Zones: Used on wheat flour packaging machine guards, withstanding high humidity and occasional washdown splashes.
