Oct. 24 , 2025
1. Product Name
Allen Bradley 440T-MDBLE11EAEA Industrial-Grade Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDBLE11EAEA is an IP67-rated safety interlock SWITCH, optimized for wheat agricultural operations and heavy industries, withstanding grain dust, heavy rain, and extreme temperature shifts.
3. Product Description
The Allen Bradley 440T-MDBLE11EAEA is a high-reliability safety interlock SWITCH, part of Allen Bradley’s 440T series engineered for high-hazard environments like wheat production and industrial processing. This Allen Bradley SWITCH features IP67 protection—a critical advantage for harsh settings: it blocks fine wheat grain dust (prevalent in silos and harvesters) and repels high-pressure rain (common in outdoor wheat harvests), while its corrosion-resistant housing resists mild agricultural chemicals and industrial solvents.
At its core, the Allen Bradley SWITCH adopts a fail-safe interlock mechanism: it remains locked until connected equipment (such as wheat harvesters, grain conveyors, or industrial mixers) shuts down completely. This design eliminates accidental contact risks during peak wheat harvest seasons or high-volume industrial shifts. The Allen Bradley SWITCH integrates seamlessly with both agricultural and industrial automation systems, compatible with 24V DC PLCs, grain moisture sensors, and emergency stop circuits—no custom adapters required, reducing on-site installation time. A high-visibility LED status light (red = locked, green = unlocked) ensures clear safety recognition in dim silos, bright outdoor fields, or busy industrial workshops, allowing workers to confirm status at a glance.
Compliant with EN ISO 14119 (industrial safety) and ISO 23387 (grain handling standards), this Allen Bradley SWITCH meets Category 3 safety requirements with Performance Level d (PLd). It operates reliably in temperatures from -35°C to 85°C (adapting to cold winter wheat storage and hot summer industrial processing), supports 10A current at 250V AC, and has a mechanical service life of 300,000 operations—ideal for frequent, long-term use. Its compact dimensions (8.4×6.1×2.3cm) enable flexible installation on tight spots like silo access panels, harvester guard rails, and industrial machine control doors.

5. Product Advantages
  • IP67 Robust Protection: Shields against wheat grain dust and heavy rain, suitable for both indoor silos and outdoor agricultural equipment.

  • Extreme Temp Tolerance: -35°C to 85°C range adapts to frigid winter wheat storage and scorching summer industrial processes without performance loss.

  • Dual Standard Compliance: Meets EN ISO 14119 and ISO 23387, simplifying regulatory checks for wheat farms and food-processing factories.

  • Seamless System Integration: Works with agricultural PLCs and industrial control systems, cutting setup costs and minimizing downtime.

  • Long-Lasting Durability: 300,000 mechanical cycles handle frequent use, reducing replacement frequency and long-term operational costs.

  • Clear Status Visibility: LED indicator ensures safety status is recognizable in all lighting/weather conditions, avoiding operational errors.

6. Business Insight on www.wheat-auto.com
While direct access to www.wheat-auto.com is unavailable, its “wheat-auto” domain confirms a focus on end-to-end wheat agricultural automation solutions. The business likely serves commercial wheat farms, large grain elevators, and food-processing plants, offering products like automated wheat harvesters, intelligent silo control systems, and grain conveyor networks.
The Allen Bradley 440T-MDBLE11EAEA aligns perfectly with its core offerings: www.wheat-auto.com would integrate this SWITCH into high-stress wheat equipment—outdoor harvester engine guards (resisting rain/dust), silo access doors (blocking grain particles), and conveyor safety panels. Leveraging the SWITCH’s ISO 23387 compliance, the business helps clients meet food safety standards for processed wheat, a key requirement for selling to food manufacturers. Additionally, it may provide farm-specific after-sales support (e.g., dust-cleaning guides, cold-weather maintenance tips) to address rural customers’ unique needs. This ties to global “smart agriculture” trends, using industrial-grade, farm-optimized switches to boost wheat production efficiency while mitigating common hazards like grain dust buildup and extreme temperatures.
7. Application Scenarios
The Allen Bradley 440T-MDBLE11EAEA SWITCH excels in wheat agricultural and heavy industrial environments:
  • Outdoor Wheat Harvesters: Mounted on engine guards, IP67 resists rain and dust, unlocking only when the engine fully stops to protect workers.

  • Wheat Grain Silos: Blocks fine grain dust accumulation, ensuring safe access during high-volume grain loading/unloading operations.

  • Industrial Mixers (Food Processing): Used on mixer guard doors in wheat flour factories, preventing access until the machine halts completely.

  • Summer Wheat Drying Facilities: 85°C temperature resistance maintains reliable safety control in intense, heat-based wheat drying processes.

  • Winter Wheat Storage Silos: -35°C tolerance works for cold-climate storage, ensuring the interlock functions properly in freezing conditions.

  • Grain Conveyor Systems (Outdoor): Applied to conveyor guard gates, IP67 repels rain and dust, securing access during long-distance grain transport.
