Oct. 22 , 2025
1. Product Name
Allen Bradley 440T-MDALE10XRXS Extreme Temperature Weatherproof Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALE10XRXS is an IP67-rated, extreme-temperature safety interlock SWITCH, engineered for -40°C to 90°C environments—ideal for wheat farms (hot summers/cold winters) and high-heat industrial zones, ensuring all-weather safety.
3. Product Description
The Allen Bradley 440T-MDALE10XRXS is a rugged safety interlock SWITCH, part of Allen Bradley’s 440T series designed for safety-critical operations in extreme thermal and harsh conditions. This Allen Bradley SWITCH acts as a reliable barrier, restricting access to hazardous equipment—such as summer wheat harvesters (exposed to high sun heat), winter grain silos (freezing temperatures), or industrial high-heat ovens—only when machinery is fully powered off, protecting workers and avoiding thermal-related equipment damage.
Constructed with 316L stainless steel housing (enhanced corrosion resistance vs. standard 316) and high-temperature silicone gaskets, the Allen Bradley SWITCH achieves IP67 protection, blocking dust, temporary water submersion (1m for 30 mins), and withstanding both freezing rain and intense sunlight. Its internal components (e.g., nickel-plated brass contacts) are treated with high-temperature oxidation-resistant coatings, ensuring stable signal transmission even at 90°C—solving overheating failures common in standard switches. The Allen Bradley SWITCH features a fail-safe interlock mechanism that remains engaged until connected systems shut down, eliminating accidental access in extreme temperature fluctuations. It supports multi-voltage compatibility (24V DC/110V AC/230V AC), enabling seamless integration with wheat farm sensors (e.g., temperature monitors, grain moisture detectors) and industrial PLCs without custom wiring, reducing on-site setup time.
Compliant with EN ISO 14119, IEC 60947-5-1, and FDA 21 CFR Part 177, this Allen Bradley SWITCH meets Category 3 safety requirements (Performance Level d, PLd) and food-contact standards. It handles 95% non-condensing humidity, supports 8A current at 250V AC, and has a 350,000-operation mechanical life. With compact dimensions (8.9×6.5×2.6cm), the Allen Bradley SWITCH fits space-constrained setups—from small harvester engine guards to tight industrial oven panels—while balancing extreme temp resistance, durability, and food safety compliance.

5. Product Advantages

  • Extreme Temp Range: -40°C to 90°C adapts to wheat farm winters (freezing) and summer industrial high-heat zones.

  • Enhanced IP67 Protection: Blocks dust, water, and thermal damage, ideal for outdoor/harsh indoor use.

  • 316L Stainless Steel: Superior corrosion resistance vs. standard 316, enduring wheat farm fertilizers and industrial chemicals.

  • Food-Grade Compliance: FDA-approved gaskets prevent wheat grain contamination, meeting agri-food standards.

  • Flexible Integration: Multi-voltage support works with farm sensors/PLCs, cutting installation costs.

  • Long-Lasting: 350,000 mechanical cycles and high-temp coatings minimize maintenance/replacement needs.

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 (especially regions with extreme seasonal temps), grain elevators, and flour processors with solutions like temperature-controlled silos, automated harvesters, and grain drying lines.
The Allen Bradley 440T-MDALE10XRXS solves the business’s key pain point: extreme temperature fluctuations. For example, its -40°C resistance prevents switch freezing in winter wheat storage yards, while 90°C tolerance avoids overheating in summer harvesters. www.wheat-auto.com would integrate this Allen Bradley SWITCH into high-risk temp-sensitive equipment—winter silo access doors, summer harvester engine guards, and grain dryer safety panels—to help clients meet ISO 23387 (grain handling safety) and local agri regulations. Additionally, the business likely offers temp-specific after-sales support (e.g., thermal coating inspection, winter freeze protection checks) to ensure reliability year-round. This alignment leverages industrial-grade extreme-temp safety components to boost wheat production efficiency, fitting the “smart agriculture” trend for resilient, season-adaptable automation.
7. Application Scenarios
The Allen Bradley 440T-MDALE10XRXS SWITCH excels in extreme-temperature, harsh environments:

  • Summer Wheat Harvesters: Installed on engine guards—90°C resistance withstands sun-heated surfaces, trapping keys until shutdown.

  • Winter Grain Silos: Mounted on access doors—-40°C resilience prevents freezing, ensuring safe access during cold-weather unloading.

  • Industrial High-Heat Ovens: Used on oven access panels—high-temp coating avoids contact failure at 90°C, protecting workers.

  • Desert Wheat Farms: Applied to outdoor conveyor guards—resists intense sunlight (90°C) and sand dust (IP67), maintaining safety.

  • Fertilizer-Treated Wheat Fields: Installed on tractor equipment—316L steel resists chemical corrosion, IP67 blocks rain/dust.

  • Temperature-Controlled Grain Dryers: Integrated into dryer safety gates—handles temp swings (10°C to 80°C) during drying cycles, ensuring safe maintenance.
