1. Product Name
Allen Bradley 440T-MDALE103DEW3DEX IP67 Industrial Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALE103DEW3DEX is an IP67-rated industrial safety interlock SWITCH, optimized for high-moisture wheat agricultural and heavy-industrial settings. It features food-grade materials, water/dust resistance (including short submersion), and impact durability.
3. Product Description
The Allen Bradley 440T-MDALE103DEW3DEX is a high-reliability industrial safety interlock SWITCH, part of Allen Bradley’s 440T series engineered to mitigate risks in moisture-prone wheat agriculture (rainy-field harvesting, damp grain silos, washdown processing) and heavy industries (wet mining, chemical wash zones). This Allen Bradley SWITCH acts as a critical safety barrier, linking wheat harvester guards, damp silo access doors, and industrial equipment panels to restrict entry until machinery is fully deactivated—preventing injuries from moving parts or grain moisture-related hazards.
Constructed with food-grade reinforced glass-fiber polymer housing and 304 stainless steel internals, the Allen Bradley SWITCH achieves IP67 protection: it blocks fine wheat dust, resists high-pressure water jets (100bar), and endures short-term submersion (up to 1m for 30 minutes)—vital for rainy wheat farms or flooded industrial areas. All materials comply with FDA 21 CFR Part 177, eliminating wheat grain/flour contamination risks during processing. Its fail-safe interlock mechanism stays engaged until connected systems power off, avoiding accidental access from operational errors. This Allen Bradley SWITCH supports multi-voltage compatibility (24V DC/110V AC/230V AC), enabling seamless integration with wheat agricultural sensors (e.g., moisture detectors) and industrial PLCs without adapters.
Compliant with EN ISO 14119 and IEC 60947-5-1, this Allen Bradley SWITCH meets Category 3 safety requirements (PLd). It operates reliably in -30°C to 70°C, handles 95% non-condensing humidity, and supports 10A at 250V AC. With a 250,000-operation mechanical life and compact size (9.1×6.8×2.9cm), it balances durability, moisture resistance, and space efficiency for tight installations like wheat harvester panels or damp silo ports.

  • Wide Temperature Range: -30°C to 70°C suits winter wheat silos and high-heat industrial washdowns.

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

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

  • Low Maintenance: Sealed internals minimize upkeep, reducing downtime for wheat and industrial operations.

6. Business Insight on www.wheat-auto.com
While direct site access is unavailable, “wheat-auto” confirms its focus on end-to-end wheat agricultural automation solutions—serving commercial farms, grain elevators, and flour mills with automated harvesters, damp silo systems, and washdown processing lines.
The Allen Bradley 440T-MDALE103DEW3DEX aligns with its core needs: IP67 protects against rainy wheat fields and damp silos, while food-grade materials meet wheat processing safety norms. www.wheat-auto.com would integrate this SWITCH into critical setups—rainy-field harvester guards (resisting downpours), damp silo doors (withstanding moisture), and flour mill wash zones (handling high-pressure cleaning). It would leverage the SWITCH’s multi-voltage compatibility to pair with existing agri-sensors (e.g., grain moisture monitors), creating unified safety workflows. This fits “smart agriculture” trends, using industrial-grade moisture-resistant components to boost wheat efficiency while ensuring food safety.
7. Application Scenarios
The Allen Bradley 440T-MDALE103DEW3DEX SWITCH excels in high-moisture wheat agri and industrial environments:
  • Rainy-Field Wheat Harvesters: Installed on engine guards—IP67 resists rain and mud, trapping keys until shutdown.

  • Damp Grain Silos: Mounted on access doors—blocks moisture and grain dust, ensuring safe entry post-unloading.

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

  • Wet Mining Conveyors: Used on ore belt guards—IP67 resists water and mineral dust, stainless steel fights corrosion.

  • Wheat Pesticide Wash Stations: Applied to drum guards—waterproof design prevents spill damage, interlock ensures safe access.

  • Winter Damp Silos: Installed on cold-storage doors—-30°C resilience + moisture resistance maintains safety in freezing damp conditions.
