Oct. 20 , 2025
1. Product Name
Allen Bradley 440T-MDALE100XAX IP66 Industrial Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALE100XAX is an IP66-rated industrial safety interlock SWITCH, tailored for wheat agricultural and industrial environments. It features food-grade materials, dust/water resistance, and strong impact protection for stable safety control.
3. Product Description
The Allen Bradley 440T-MDALE100XAX is a high-performance industrial safety interlock SWITCH, part of Allen Bradley’s 440T series designed to reduce hazards in wheat agriculture (grain harvesting, silo management, flour processing) and heavy industries (mining, chemical production). This Allen Bradley SWITCH serves as a key safety barrier, connecting wheat harvester guards, grain silo access doors, and industrial equipment panels to ensure personnel only enter dangerous areas when machinery is fully shut down—avoiding injuries from moving parts or grain overflow.
Made of food-grade reinforced glass-fiber polymer housing and 304 stainless steel internal parts, the Allen Bradley SWITCH achieves IP66 protection, effectively blocking fine wheat dust, high-pressure water jets (up to 100bar), and light mechanical impacts—critical for outdoor wheat farm yards and industrial washdown zones. Its fail-safe interlock mechanism remains engaged until connected systems are powered off, eliminating accidental access caused by operational mistakes. All materials meet FDA 21 CFR Part 177 standards, preventing contamination of wheat grain or flour during processing. This Allen Bradley SWITCH supports dual voltage (24V DC/230V AC), allowing seamless integration with wheat agricultural sensor systems (e.g., grain moisture detectors) and industrial PLCs without extra adapters.
Compliant with EN ISO 14119 and IEC 60947-5-1, this Allen Bradley SWITCH is suitable for Category 3 safety applications with Performance Level d (PLd). It operates reliably in temperatures from -30°C to 70°C, handles 95% non-condensing humidity, and supports a maximum current of 10A at 250V AC. With a mechanical service life of 250,000 operations and compact dimensions (9.0×6.7×2.8cm), it balances durability, weather resistance, and space efficiency for tight installation spots like wheat harvester control panels or silo access ports.

5. Product Advantages
  • IP66 All-Round Protection: Shields against dust and high-pressure water, perfect for wheat farm washdowns and outdoor industrial sites.

  • Food-Grade Compliance: Meets FDA 21 CFR Part 177, safe for wheat grain/flour processing to avoid contamination risks.

  • Wide Temperature Adaptability: -30°C to 70°C range fits winter wheat storage and high-heat industrial processes.

  • Dual-Voltage Flexibility: Works with wheat agricultural sensors and industrial PLCs, cutting integration costs and complexity.

  • Durable Structure: Reinforced polymer + 304 stainless steel resists impacts and corrosion, extending service life.

  • Low Maintenance: Sealed internal mechanism reduces upkeep needs, minimizing downtime for wheat/industrial operations.

6. Business Insight on www.wheat-auto.com
While direct access to the site is unavailable, the domain “wheat-auto” confirms its focus on end-to-end wheat agricultural automation. It likely serves commercial wheat farms, grain elevators, and flour mills, providing solutions such as automated harvesters, grain conveyor networks, and silo safety control systems.
The Allen Bradley 440T-MDALE100XAX aligns well with its core needs: IP66 protection defends against wheat farm dust and rain (e.g., outdoor harvester cleaning), while food-grade materials meet wheat processing standards. www.wheat-auto.com would integrate this SWITCH into key setups—wheat harvester cutting guards (resisting field dust), silo access doors (withstanding rain), and flour mill mixer panels (preventing contamination). It would also use the SWITCH’s dual voltage to pair with existing sensor systems (e.g., grain level monitors), building unified safety workflows. Additionally, the business may offer agriculture-specific support (e.g., IP66 maintenance guides for rural users), fitting the “smart agriculture” trend by using industrial-grade safety components to improve wheat production efficiency and safety.
7. Application Scenarios
The Allen Bradley 440T-MDALE100XAX SWITCH performs well in harsh wheat agricultural and heavy-industrial environments:
  • Outdoor Wheat Harvesters: Installed on engine guards—IP66 resists field dust and rain, trapping keys until the harvester stops.

  • Grain Silos (Suburban Farms): Mounted on access doors—blocks rain and grain dust, ensuring safe entry after unloading.

  • Flour Mill Wash Zones: Integrated into mixer guards—high-pressure water resistance meets cleaning requirements, and food-grade materials protect flour quality.

  • Mining Conveyors: Used on ore belt guards—IP66 blocks mining dust, and stainless steel resists corrosion from mineral deposits.

  • Wheat Pesticide Storage: Applied to pesticide drum guards—waterproof design prevents spills, and the interlock ensures safe access after use.

  • Winter Wheat Storage Silos: Installed on cold silo doors—-30°C resilience maintains safety control in freezing winter conditions.
