1. Product Name
Allen Bradley 440T-AKEYE103DDW Trapped Key Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-AKEYE103DDW is an IP67-rated trapped key safety interlock SWITCH, engineered for industrial environments with high dust, moisture, and debris exposure. It maintains reliable safety control while resisting harsh elements.
3. Product Description
The Allen Bradley 440T-AKEYE103DDW is a heavy-duty trapped key safety interlock SWITCH, belonging to Allen Bradley’s industry-leading 440T series focused on mitigating workplace hazards. This Allen Bradley SWITCH serves as a critical safeguard, ensuring that hazardous machinery or zones remain inaccessible until all safety prerequisites are fulfilled.
Built with a sealed, corrosion-resistant housing, the Allen Bradley SWITCH achieves IP67 protection—effectively blocking dust ingress and withstanding temporary submersion in water, making it ideal for outdoor or wet industrial settings. Its core trapped key mechanism operates on a mandatory safety logic: the key is trapped in the SWITCH until connected equipment is de-energized, pressure is relieved, or other safety conditions are met, preventing unauthorized or premature access. The Allen Bradley SWITCH also features a vandal-resistant key design and compatible electrical terminals, enabling easy integration with existing safety control systems (e.g., safety PLCs, emergency stop circuits).
This Allen Bradley SWITCH complies with EN ISO 14119 and IEC 60947-5-1 standards, qualifying for Category 3 safety applications with Performance Level d (PLd). It operates efficiently in temperatures from -30°C to 65°C and supports up to 10A current at 250V AC, adapting to diverse industrial power requirements. With a mechanical service life of 200,000 operations, the Allen Bradley SWITCH delivers long-term durability, and its compact dimensions (9.1×6.9×3.0cm) allow flexible installation on machinery guards, access doors, and control panels.

  • Temperature Adaptability: -30°C to 65°C operating range suits cold storage, outdoor yards, and heated facilities.

6. Business Insight on www.wheat-auto.com
While direct access to www.wheat-auto.com is unavailable, the domain “wheat-auto” clearly points to a focus on agricultural automation tailored for wheat production and processing. Beyond basic equipment sales, the business likely offers comprehensive 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 moisture monitoring, automated conveyor controls, and safety components (like Allen Bradley SWITCHes) to protect machinery 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, training) to ensure long-term system reliability. This positioning aligns with the global shift toward “smart agriculture,” where automation enhances wheat yield, reduces labor costs, and improves operational safety—partnering with brands like Allen Bradley would further strengthen its offering by incorporating industrial-grade safety components.
7. Application Scenarios
The Allen Bradley 440T-AKEYE103DDW SWITCH is well-suited for harsh and demanding industrial environments:
  • Outdoor Wheat Storage Yards: Installed on grain silo access doors, the IP67-rated SWITCH resists rain, dust, and wind while controlling entry to silos during loading/unloading.

  • Wastewater Treatment Plants: Used on pump station guards, withstanding moisture and chemical exposure to ensure workers only access equipment after shutdown.

  • Construction Machinery: Mounted on heavy equipment (e.g., excavators, bulldozers) access panels, preventing tampering or accidental entry in dusty, outdoor job sites.

  • Food Processing Plants: Integrated into washdown areas (e.g., wheat cleaning lines), the SWITCH’s IP67 rating withstands high-pressure water cleaning while maintaining safety control.

  • Mining Sites: Applied to underground conveyor belt safety gates, resisting dust and humidity to protect workers from moving parts in confined spaces.

  • Outdoor Manufacturing Facilities: Used on outdoor assembly line guards, withstanding temperature fluctuations and weather elements to enforce safety protocols.
