Oct. 21 , 2025
1. Product Name
Allen Bradley 440T-MDALE103ADU3ADS IP66 Industrial Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALE103ADU3ADS is an IP66-rated industrial safety interlock SWITCH, tailored for wheat agricultural and heavy-industrial environments. It features food-grade materials, dust/water resistance, and impact durability to ensure reliable hazard prevention.
3. Product Description
The Allen Bradley 440T-MDALE103ADU3ADS is a high-performance industrial safety interlock SWITCH, part of Allen Bradley’s 440T series engineered to address risks in wheat agriculture (grain harvesting, silo management, flour processing) and heavy industries (mining, chemical production). This Allen Bradley SWITCH acts as a critical safety link, connecting wheat harvester guards, grain silo access doors, and industrial equipment panels to restrict access until machinery is fully deactivated—avoiding injuries from moving parts or grain overflow.
Constructed with food-grade reinforced glass-fiber polymer housing and 304 stainless steel internals, the Allen Bradley SWITCH achieves IP66 protection, blocking fine wheat dust, high-pressure water jets (up to 100bar), and light impacts—essential for outdoor wheat farms and industrial washdown areas. All materials comply with FDA 21 CFR Part 177, preventing contamination of wheat grain or flour during processing. Its fail-safe interlock mechanism remains engaged until connected systems power off, eliminating accidental access from operational errors. This Allen Bradley SWITCH supports multi-voltage (24V DC/110V AC/230V AC) compatibility, enabling seamless integration with wheat agri sensors (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 meets Category 3 safety standards with Performance Level d (PLd). It operates reliably in -30°C to 70°C temperatures, handles 95% non-condensing humidity, and supports 10A current at 250V AC. With a 250,000-operation mechanical life and compact dimensions (9.1×6.8×2.9cm), it balances durability, weather resistance, and space efficiency for tight installations like wheat harvester control panels or silo access ports.

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

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

  • Broad Temperature Range: -30°C to 70°C adaptability suits winter wheat storage and high-heat industrial processes.

  • Multi-Voltage Flexibility: Works with wheat agri sensors and industrial PLCs, reducing integration costs.

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

  • Low Maintenance: Sealed internals minimize upkeep, cutting downtime for wheat/industrial operations.

6. Business Insight on www.wheat-auto.com
While direct site access is unavailable, the domain “wheat-auto” confirms its focus on end-to-end wheat agricultural automation—serving commercial wheat farms, grain elevators, and flour mills with solutions like automated harvesters, grain conveyors, and silo safety systems.
The Allen Bradley 440T-MDALE103ADU3ADS aligns perfectly with its needs: IP66 protection defends against wheat farm dust/rain (e.g., outdoor harvester cleaning), and food-grade materials meet wheat processing safety standards. www.wheat-auto.com would integrate this SWITCH into critical setups—wheat harvester cutting guards (resisting field dust), silo access doors (withstanding rain), and flour mill mixer panels (preventing contamination). It would also leverage the SWITCH’s multi-voltage compatibility to pair with existing sensors (e.g., grain level monitors), creating unified safety workflows. This fits “smart agriculture” trends, using industrial-grade safety components to boost wheat production efficiency and safety.
7. Application Scenarios
The Allen Bradley 440T-MDALE103ADU3ADS SWITCH excels in harsh wheat agri and heavy-industry environments:
  • Wheat Harvesters (Outdoor Fields): Installed on engine guards—IP66 resists dust/rain, trapping keys until shutdown.

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

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

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

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

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