1. Product Name
Allen Bradley 440T-MDBLE15OOOP Industrial Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDBLE15OOOP is an IP67-rated safety interlock SWITCH, engineered for wheat agricultural and heavy industrial environments. It resists grain dust, moisture, and corrosion for stable safety performance.
3. Product Description
The Allen Bradley 440T-MDBLE15OOOP is a high-performance safety interlock SWITCH, part of Allen Bradley’s 440T series tailored for high-hazard settings like wheat harvest lines, grain silos, and industrial processing plants. This Allen Bradley SWITCH boasts IP67 ingress protection—a critical feature for harsh conditions: it blocks fine wheat grain dust (prevalent in silo loading and flour milling) and repels high-pressure water (common in outdoor wheat harvesting or industrial washdowns). Its reinforced housing, made with anti-corrosion materials, withstands mild pesticides on wheat farms and industrial lubricants, avoiding premature wear.
At its core, the Allen Bradley SWITCH adopts a fail-safe interlock mechanism: it stays locked until connected equipment (such as wheat harvesters, grain conveyors, or industrial mixers) fully shuts down and safety signals are verified. This design eliminates accidental contact risks during peak wheat production or high-volume industrial operations. The SWITCH supports multi-voltage compatibility (24V DC/110V AC/230V AC), enabling seamless integration with agricultural PLC systems (for wheat farm automation) and industrial control panels—no custom adapters needed, reducing on-site installation time. A high-visibility LED indicator (red = locked, green = unlocked) ensures clear status recognition in dim silos, bright outdoor fields, or noisy workshops, minimizing errors from unclear safety signals.
Compliant with EN ISO 14119 (industrial safety), ISO 23387 (grain handling safety), and IEC 60947-5-1, this Allen Bradley SWITCH meets Category 3 safety requirements with Performance Level d (PLd). It operates reliably in a temperature range of -35°C to 80°C, adapts to 95% non-condensing humidity, supports 10A current at 250V AC, and has a mechanical service life of 280,000 operations. Its compact size (8.8×6.5×2.6cm) allows flexible installation on silo panels, harvester guard rails, and machine access doors.

5. Product Advantages
  • IP67 & Anti-Corrosion: Resists wheat dust, high-pressure water, and mild chemicals, extending service life in harsh farm/industrial environments.

  • Wide Temperature Range: -35°C to 80°C adaptability suits winter wheat storage and hot summer industrial processing.

  • Dual Standard Compliance: Meets EN ISO 14119 and ISO 23387, simplifying regulatory checks for wheat farms and grain facilities.

  • Multi-Voltage Flexibility: Works with 24V DC (agricultural sensors) and 230V AC (industrial machinery), cutting integration costs.

  • Long-Lasting Durability: 280,000 mechanical cycles reduce replacement frequency, lowering operational expenses.

  • Clear Status Indication: High-visibility LED prevents misoperation in dim silos or bright outdoor fields.

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 wheat-processing plants, offering products like automated harvesters, intelligent silo control systems, and grain conveyor networks.
The Allen Bradley 440T-MDBLE15OOOP aligns with the website’s core offerings: www.wheat-auto.com would integrate this SWITCH into high-stress wheat equipment—outdoor harvester engine guards (resisting rain and pesticides), silo access doors (blocking grain dust), and humid storage conveyor panels. Its ISO 23387 compliance solves a key client pain point, helping farms meet strict grain handling safety standards. The SWITCH’s multi-voltage compatibility also adapts to farms’ mixed power setups (e.g., 24V DC moisture sensors and 230V AC conveyors). Additionally, the business may provide farm-specific after-sales support (e.g., corrosion inspection, dust-cleaning guides) to address rural operational challenges, aligning with “smart agriculture” trends by using industrial-grade, farm-optimized switches to boost wheat efficiency and safety.
7. Application Scenarios
The Allen Bradley 440T-MDBLE15OOOP SWITCH excels in wheat agricultural and heavy industrial environments:
  • Outdoor Wheat Harvesters: Mounted on engine guards, IP67 resists rain and pesticides, unlocking only when the engine stops to protect operators.

  • Wheat Grain Silos: Blocks fine dust and resists mild chemicals, ensuring safe access during loading/unloading in dim or humid silos.

  • Wheat Flour Mills: Used on mixer guards, preventing access until the machine halts, complying with food processing safety norms.

  • High-Temp Wheat Drying Facilities: 80°C tolerance maintains safety control in heat-based wheat drying processes.

  • Winter Wheat Storage Silos: Withstands -35°C temperatures, functioning normally in freezing cold storage environments.

  • Humid Grain Conveyors: Resists moisture in damp storage facilities, ensuring reliable interlock performance during wheat transport.
