Oct. 22 , 2025
1. Product Name
Allen Bradley 440T-MDALE45FOFP High-Temperature Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALE45FOFP is an IP67/high-temperature safety interlock SWITCH, engineered for -40°C~120°C environments—ideal for wheat drying systems and industrial high-heat zones, ensuring reliable safety control under extreme heat.
3. Product Description
The Allen Bradley 440T-MDALE45FOFP is a specialized high-temperature safety interlock SWITCH, part of Allen Bradley’s 440T series designed for safety-critical operations in extreme heat. This Allen Bradley SWITCH acts as a vital barrier, restricting access to high-risk equipment—such as wheat farm drying ovens, industrial kilns, or high-temperature grain storage units—only when systems cool to safe temperatures or fully shut down, protecting workers from thermal burns and equipment damage.
Constructed with Inconel alloy housing (resists oxidation at 120°C and withstands wheat drying byproducts like dust and heat-induced moisture) and silicone rubber seals, the Allen Bradley SWITCH achieves IP67 protection—blocking dust ingress and temporary water immersion (1m/30min), solving pain points like post-drying washdowns and heat-related seal degradation. Its internal components use ceramic insulators (heat-resistant up to 150°C) and silver-plated contacts (stable signal transmission under high heat), ensuring reliability in wheat drying facilities with fluctuating temperatures (95% non-condensing humidity). The Allen Bradley SWITCH integrates a heat-sensing interlock mechanism: the lock remains engaged until connected systems cool below 50°C (via built-in temperature sensor) or power off, eliminating accidental access to hot equipment. It supports wide voltage compatibility (24V DC~230V AC), enabling seamless integration with wheat drying sensors (temperature monitors, moisture detectors) and industrial PLCs without additional adapters, reducing setup time.
Compliant with EN ISO 14119, IEC 60947-5-1, and ISO 23387 (grain handling safety), this Allen Bradley SWITCH meets Category 3 safety requirements (Performance Level d, PLd) and suits wheat high-heat processes. It handles 10A current at 250V AC, boasts a 300,000-operation mechanical life, and has compact dimensions (8.9×6.5×2.7cm)—fitting space-constrained setups like wheat dryer access panels or industrial kiln guards.

5. Product Advantages
  • Extreme Heat Resilience: -40°C~120°C range suits wheat drying (100°C+) and industrial kilns, no heat-induced performance loss.

  • IP67 Protection: Dust-tight + temporary water resistance, ideal for post-drying washdowns and humid farm environments.

  • Grain-Safe Design: Inconel housing resists wheat dust/byproducts, complying with ISO 23387 for food-related operations.

  • Heat-Sensing Safety: Built-in temp sensor unlocks only when cool, preventing thermal burn risks.

  • Long Durability: 300,000 cycles + ceramic components reduce maintenance, lowering long-term costs.

  • Easy Integration: Wide voltage compatibility works with farm sensors and industrial PLCs, simplifying installation.

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 dryers, and food processors with solutions like automated drying systems, high-temperature grain storage controls, and post-harvest processing lines.
The Allen Bradley 440T-MDALE45FOFP solves the business’s key challenge: safety in wheat high-heat processes (drying, roasting). www.wheat-auto.com would integrate this SWITCH into core high-temperature equipment—wheat dryer access doors (withstanding 120°C internal heat), high-heat grain conveyor guards (resisting post-drying residual heat), and roasted wheat processing machine enclosures (IP67 for washdowns). It leverages the SWITCH’s ISO 23387 compliance to help clients meet agricultural safety regulations, while the built-in temperature sensor aligns with the business’s automated temperature monitoring systems. Additionally, the business likely offers farm-specific after-sales support (heat-sensor calibration, high-temperature seal replacement) to address wheat drying season demands. This alignment with “smart agriculture” uses industrial-grade high-heat components to boost wheat drying efficiency and worker safety.
7. Application Scenarios
The Allen Bradley 440T-MDALE45FOFP SWITCH excels in high-temperature, semi-harsh environments:
  • Wheat Drying Ovens: Mounted on oven access doors—120°C resilience unlocks only when cool, IP67 handles post-drying washdowns.

  • Industrial Kilns: Installed on kiln guards—resists 120°C heat, prevents access to hot ceramic/metal processing zones.

  • High-Temp Grain Storage: Used on storage bin doors—withstands residual heat from dried wheat, IP67 blocks dust and rain.

  • Roasted Wheat Processors: Integrated into processor guards—heat-sensing ensures safe access, IP67 handles cleaning sprays.

  • Automotive Paint Curing Ovens: Applied to oven access panels—resists curing heat (100°C+), stable signal under high temp.

  • Plastic Molding Machines: Mounted on mold guards—withstands 120°C machine heat, IP67 blocks plastic dust and coolant splashes.
