1. Product Name
Allen Bradley 440T-AKEYS10WK Trapped Key Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-AKEYS10WK is an IP67/weatherproof trapped key safety interlock SWITCH, designed for outdoor damp/dusty environments—ideal for wheat farm equipment and industrial outdoor setups.
3. Product Description
The Allen Bradley 440T-AKEYS10WK is a rugged, weather-resistant trapped key safety interlock SWITCH, part of Allen Bradley’s 440T series engineered to solve safety challenges in outdoor and high-moisture settings. This Allen Bradley SWITCH acts as a critical safety barrier, ensuring personnel only access hazardous zones (e.g., outdoor wheat harvesters, silo exteriors) when equipment is fully shut down and environmental risks (rain, dust) are managed.
Constructed with IP67-rated sealed housing and 316 stainless steel components, the Allen Bradley SWITCH resists heavy rain, dust accumulation, and mild corrosion—key for wheat farms exposed to outdoor elements. Its core trapped key mechanism follows a fail-safe design: the key remains locked in the SWITCH until connected systems (e.g., outdoor conveyors, silo loading gates) are de-energized, preventing accidental contact with moving parts or exposure to weather-related hazards. The Allen Bradley SWITCH features 24V DC/230V AC compatible terminals, enabling seamless integration with wheat farm automation controls (e.g., harvester management systems) and industrial safety PLCs.
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 -40°C to 70°C, handles 95% non-condensing humidity, and supports a maximum current of 10A at 250V AC. With a mechanical service life of 220,000 operations and compact dimensions (9.1×6.9×2.8cm), the Allen Bradley SWITCH balances weather resilience, safety performance, and space efficiency for tight outdoor installations like harvester guard doors.

5. Product Advantages

  • IP67 Weatherproofing: Blocks heavy rain and dust, ideal for outdoor wheat farm equipment (e.g., harvesters, silo exteriors).

  • Corrosion Resistance: 316 stainless steel components withstand mild salt spray or damp farm conditions, extending service life.

  • Wide Temperature Adaptability: -40°C to 70°C range suits cold winter wheat storage and warm summer harvesting.

  • Rigorous Safety Compliance: PLd/Category 3 rating meets global agricultural/industrial standards, preventing weather-related accidents.

  • Easy Integration: Multi-voltage terminals work with farm automation systems and industrial PLCs, reducing setup time.

  • Durable Performance: 220,000-cycle mechanical life minimizes replacement costs for high-use outdoor equipment.

6. Business Insight on www.wheat-auto.com
While direct site access is unavailable, the domain “wheat-auto” confirms a focus on wheat-centric agricultural automation—specializing in outdoor and indoor equipment for wheat harvesting, storage, and processing. The business likely serves commercial wheat farms, grain elevators, and food processors, offering customized solutions like automated harvesters, outdoor conveyor networks, and silo safety systems.
Given the Allen Bradley 440T-AKEYS10WK’s IP67/weatherproof features, www.wheat-auto.com would integrate this SWITCH into outdoor wheat equipment: harvester engine guards (resisting rain/dust), silo loading gate locks (withstanding damp storage conditions), and outdoor grain transport conveyors (tolerating winter cold). It would leverage the SWITCH’s compliance with agricultural standards (e.g., ISO 23387 for grain handling) to ensure safety in unprotected farm environments—critical for preventing accidents during rainy harvests or dusty silo operations. Additionally, the business probably offers farm-specific after-sales support (e.g., weatherproofing inspections, corrosion maintenance) to keep the SWITCH functional in harsh outdoor conditions, aligning with “smart agriculture” trends that prioritize durable, safe automation.
7. Application Scenarios
The Allen Bradley 440T-AKEYS10WK SWITCH excels in outdoor and damp industrial/agricultural environments:

  • Outdoor Wheat Harvesters: Installed on harvester fuel tank guards, IP67 resists rain and dust while trapping keys until the engine stops.

  • Silo Exterior Gates: Mounted on silo loading/unloading doors, weatherproofing handles damp storage conditions and prevents unauthorized access.

  • Outdoor Grain Conveyors: Used on conveyor safety gates, -40°C resilience ensures winter operation and IP67 blocks snow/mud.

  • Damp Food Processing Zones: Integrated into wheat washing equipment guards, IP67 withstands splashes and moisture.

  • Coastal Wheat Farms: Applied to outdoor storage shed doors, 316 stainless steel resists salt spray and corrosion.

  • Mining Outdoor Conveyors: Used on mineral transport guards, weatherproofing handles rain/dust and wide temp suits mine climate shifts.
