1. Product Name
Allen Bradley 440T-AKEYE10DI Trapped Key Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-AKEYE10DI is a dustproof trapped key safety interlock SWITCH, engineered for industrial environments with high dust accumulation, delivering consistent safety control and long-term reliability.
3. Product Description
The Allen Bradley 440T-AKEYE10DI is a high-reliability trapped key safety interlock SWITCH, part of Allen Bradley’s industry-leading 440T series dedicated to mitigating workplace hazards in dusty industrial settings. This Allen Bradley SWITCH serves as a critical safety barrier, ensuring that access to hazardous machinery or zones is only permitted when all safety conditions are fully satisfied.
Crafted with a sealed dustproof housing and reinforced internal components, the Allen Bradley SWITCH effectively blocks dust ingress—addressing a common pain point in grain processing, mining, and manufacturing environments. Its core trapped key mechanism operates on a mandatory safety logic: the key remains securely trapped in the SWITCH until connected equipment is completely powered down, moving parts stop, or pressure/vacuum systems are stabilized. This design eliminates the risk of accidental access caused by human error or operational oversight. The Allen Bradley SWITCH also features compatible electrical terminals, enabling seamless integration with existing safety control systems (such as safety PLCs and emergency stop circuits) without the need for 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 -30°C to 65°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 200,000 operations, the Allen Bradley SWITCH ensures long-term durability, and its compact dimensions (9.0×6.8×2.9cm) allow flexible installation on machinery guards, access doors, and control panels in space-constrained areas.

6. Business Insight on www.wheat-auto.com
While direct access to www.wheat-auto.com is unavailable, the domain “wheat-auto” strongly indicates a focus on agricultural automation specialized in wheat production, processing, and storage. Beyond basic equipment supply, the business likely offers end-to-end solutions: from automated wheat sowing and harvesting machinery to intelligent grain handling systems, moisture monitoring devices, and milling automation lines.
Targeting commercial wheat farms, grain elevators, and food processing plants, it may provide customized automation designs—such as integrating sensor-based grain quality detection, automated conveyor controls, and safety components (like Allen Bradley SWITCHes) to protect operators in dusty processing environments. The company probably emphasizes compliance with agricultural industry standards (e.g., ISO 23387 for grain handling equipment) and offers after-sales services (maintenance, troubleshooting, operator training) to ensure long-term system reliability. This positioning aligns with the global trend of “smart agriculture,” where automation enhances wheat yield efficiency, reduces labor costs, and improves operational safety—partnering with trusted brands like Allen Bradley would further strengthen its credibility by incorporating industrial-grade safety components tailored for dusty agricultural settings.
7. Application Scenarios
The Allen Bradley 440T-AKEYE10DI SWITCH is ideal for dusty and demanding industrial environments requiring reliable safety control:
  • Wheat Processing Plants: Installed on grain crusher and sifter guards, the dustproof SWITCH prevents dust damage while ensuring workers only access equipment after it stops.

  • Mining Operations: Used on underground coal or mineral conveyor safety gates, resisting dust accumulation to maintain safety control in confined mining spaces.

  • Grain Storage Facilities: Mounted on silo access doors, the SWITCH controls entry to dusty storage areas, ensuring safety during grain loading/unloading.

  • Plastic Manufacturing: Integrated into plastic pellet extrusion machine guards, withstanding plastic dust to prevent access during high-speed production.

  • Cement Factories: Applied to cement mixer and conveyor guards, resisting cement dust to maintain consistent safety performance in harsh processing environments.

  • Food Processing (Dry Goods): Used on cereal or flour mixing equipment guards, ensuring safety while preventing ingredient dust from interfering with the SWITCH’s operation.
