Oct. 24 , 2025
1. Product Name
Allen Bradley 440T-MDBLE14PHPI Industrial Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDBLE14PHPI is an IP67-rated, corrosion-resistant safety interlock SWITCH, optimized for wheat agricultural and heavy industrial environments. It withstands grain dust, chemicals, and extreme temperatures for stable safety performance.
3. Product Description
The Allen Bradley 440T-MDBLE14PHPI is a high-performance safety interlock SWITCH, part of Allen Bradley’s 440T series engineered for high-hazard scenarios like wheat harvest lines, grain silos, and chemical-processing facilities. This Allen Bradley SWITCH features IP67 ingress protection, a critical advantage for harsh conditions: it blocks fine wheat grain dust (common in silo loading and flour milling) and repels high-pressure rain (typical during outdoor wheat harvesting), while its 316 stainless steel housing enhances corrosion resistance—ideal for wheat farms using mild pesticides or industrial sites with lubricants.
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 dual-color 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 -40°C to 85°C, adapts to 95% non-condensing humidity, supports 10A current at 250V AC, and has a mechanical service life of 300,000 operations. Its compact size (8.6×6.3×2.5cm) allows flexible installation on silo panels, harvester guard rails, and machine access doors.

5. Product Advantages

  • IP67 & Corrosion Resistance: 316 stainless steel and IP67 shield against wheat dust, rain, and mild chemicals, extending service life.

  • Wide Temperature Range: -40°C to 85°C adapts to winter wheat storage and hot summer industrial processing.

  • Dual Standard Compliance: Meets EN ISO 14119 (industrial) and ISO 23387 (grain handling), simplifying regulatory checks.

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

  • Long Durability: 300,000 mechanical cycles reduce replacement frequency, lowering operational expenses.

  • Clear Status Indication: Dual-color LED ensures visibility in all environments, avoiding human error.

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-MDBLE14PHPI 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 pesticide corrosion), silo access doors (blocking grain dust), and coastal-region conveyor panels (withstanding salt spray). 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, tying to “smart agriculture” trends by using industrial-grade, farm-optimized switches to boost wheat efficiency and safety.
7. Application Scenarios
The Allen Bradley 440T-MDBLE14PHPI SWITCH excels in wheat agricultural and heavy industrial environments:

  • Outdoor Wheat Harvesters: Mounted on engine guards, IP67 and corrosion resistance withstand rain and pesticides, unlocking only when the engine stops.

  • Wheat Grain Silos: Blocks fine dust and resists mild chemicals, ensuring safe access during loading/unloading in dim 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: 85°C tolerance maintains safety control in heat-based wheat drying processes.

  • Winter Wheat Storage Silos: Withstands -40°C temperatures, functioning normally in freezing cold storage.

  • Coastal Grain Conveyors: 316 stainless steel resists salt corrosion, IP67 blocks rain/dust during wheat transport.
