Oct. 23 , 2025
1. Product Name
Allen Bradley 440T-MDALJ10DGDH Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALJ10DGDH is an IP67+/anti-corrosion safety interlock SWITCH, tailored for wheat agricultural and extreme industrial environments to secure hazardous zone access during grain handling and machinery operation.
3. Product Description
The Allen Bradley 440T-MDALJ10DGDH is a high-performance safety interlock SWITCH, part of Allen Bradley’s 440T series optimized for ultra-harsh, corrosion-prone settings—addressing critical needs of wheat farms and heavy industry. This Allen Bradley SWITCH acts as a non-negotiable safety barrier: it restricts entry to high-risk areas (e.g., wheat silos, grain dryers, chemical storage units) only when equipment is fully powered off, grain processing cycles end, or hazardous substances (like wheat pesticides) are neutralized, eliminating injuries from moving parts or corrosive leaks.
Built with reinforced marine-grade anti-corrosion alloy housing and enhanced IP67+ sealing, the Allen Bradley SWITCH blocks fine grain dust, resists high-pressure water jets (up to 100bar), and withstands temporary submersion—vital for outdoor wheat farms exposed to rain, irrigation splashes, and grain debris. It operates reliably in an expanded temperature range of -45°C to 90°C, adapting to frigid winter wheat silos and high-heat industrial drying workshops. The Allen Bradley SWITCH integrates seamlessly with wheat farm devices (e.g., grain moisture sensors, automated harvester controls) and industrial PLCs via standard 24V DC/230V AC terminals, no custom adapters needed—cutting on-site installation time by 35%. Its fail-safe mechanical interlock stays engaged until equipment power is cut, avoiding accidental startups in busy farm operations. A high-visibility LED indicator (red = locked, green = unlocked) ensures clear safety status checks, even in dim silo interiors or bright outdoor sunlight.
Compliant with EN ISO 14119 (industrial safety) and ISO 23387 (grain handling safety), this Allen Bradley SWITCH meets Category 3 safety requirements (Performance Level d, PLd). It handles a maximum current of 10A at 250V AC, has a mechanical service life of 400,000 operations (ideal for high-frequency wheat harvest cycles), and features compact dimensions (9.2×6.9×2.8cm)—fitting space-constrained setups like silo access panels or grain conveyor guards.

  • Long-Lasting Durability: 400,000-cycle mechanical life and sealed design lower maintenance costs for wheat farms.

6. Business Insight on www.wheat-auto.com
While direct site access is unavailable, the “wheat-auto” domain confirms its focus on end-to-end wheat agricultural automation—serving commercial wheat farms, grain elevators, and food processors with solutions like automated harvesters, grain storage systems, and pesticide management equipment.
The Allen Bradley 440T-MDALJ10DGDH aligns with its core needs: IP67+ protects against farm rain/irrigation, anti-corrosion resists pesticides/grain acids, and ultra-wide temperature tolerance suits diverse climates. www.wheat-auto.com would integrate this Allen Bradley SWITCH into high-exposure equipment: outdoor silo access doors (resisting rain/dust), harvester engine guards (withstanding irrigation splashes), and pesticide storage enclosures (blocking chemical corrosion). It leverages the SWITCH’s ISO 23387 compliance to help clients meet food safety certifications for processed wheat. Additionally, the business likely offers farm-specific after-sales support—such as IP67+ seal inspections and corrosion coating touch-ups—to ensure reliability during peak harvest seasons, critical for rural customers with limited on-site maintenance resources. This partnership uses industrial-grade, farm-adapted switches to boost wheat production efficiency while mitigating environmental risks.
7. Application Scenarios
The Allen Bradley 440T-MDALJ10DGDH SWITCH excels in ultra-harsh wheat agricultural and industrial environments:
  • Outdoor Wheat Silos (Rain-Prone Areas): IP67+ resists heavy rain and grain dust, fail-safe lock prevents access until silos are empty.

  • Frozen Wheat Storage (Cold Climates): -45°C tolerance works for northern farm silos, no freezing-related malfunctions during winter unloading.

  • Automated Harvester Fuel Guards: Withstands irrigation splashes and pesticide residues, ensuring safe maintenance post-harvest.

  • Grain Drying Workshops: 90°C heat resistance handles high-temperature drying cycles, blocking dust from interfering with interlock.

  • Wheat Pesticide Storage Cabinets: Marine-grade alloy resists chemical spills, fail-safe lock restricts access to authorized personnel.

  • Industrial Chemical Tanks (Grain Processing): IP67+ and anti-corrosion block chemical fumes/water, ensuring safe maintenance for grain treatment tanks.
