Oct. 21 , 2025
1. Product Name
Allen Bradley 440T-MDALE10DFEF IP67 Industrial Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALE10DFEF is an IP67-rated, high-corrosion-resistant industrial safety interlock SWITCH, optimized for wheat agricultural (dusty harvesters, humid silos) and harsh industrial (chemical washes, coastal facilities) scenarios to ensure long-term safety and compliance.
3. Product Description
The Allen Bradley 440T-MDALE10DFEF is a heavy-duty industrial safety interlock SWITCH, part of Allen Bradley’s 440T series engineered to mitigate risks in wheat-focused agriculture and corrosive industrial environments. This Allen Bradley SWITCH acts as a critical safety barrier, linking equipment guards and access doors to restrict entry until machinery fully halts—preventing injuries from moving parts and safeguarding the integrity of wheat products.
Constructed with FDA-compliant reinforced polymer (meeting 21 CFR Part 177) and 316L stainless steel (with a double-layer anti-corrosion coating), the Allen Bradley SWITCH achieves IP67 protection: it blocks fine wheat dust, resists high-pressure water jets (up to 100bar), and endures 1m submersion for 30 minutes—effectively solving pain points like humid silo moisture, coastal salt spray, and post-harvest equipment sanitization. Its fail-safe interlock mechanism remains engaged until connected systems power off, eliminating accidental access caused by operational errors. This Allen Bradley SWITCH supports multi-voltage compatibility (24V DC/110V AC/230V AC), enabling seamless integration with wheat agri-sensors (grain moisture detectors, level monitors) and industrial PLCs without the need for additional adapters.
Compliant with EN ISO 14119 and IEC 60947-5-1 standards, this Allen Bradley SWITCH meets Category 3 safety requirements (Performance Level d, PLd). It operates reliably in a temperature range of -30°C to 80°C, handles 95% non-condensing humidity, and supports a maximum current of 10A at 250V AC. With a mechanical service life of 350,000 operations and compact dimensions (9.2×6.9×2.8cm), it balances durability, corrosion resistance, and space efficiency—ideal for tight setups like wheat harvester control panels or coastal silo access doors.

5. Product Advantages
  • IP67 All-Weather Protection: Blocks dust, resists high-pressure water, and endures submersion—perfect for rainy wheat fields and industrial washdowns.

  • Double-Layer Anti-Corrosion: 316L stainless steel with enhanced coating outperforms standard models, surviving humid silos and coastal salt spray.

  • Food-Grade Compliance: FDA 21 CFR Part 177 materials prevent wheat product contamination in flour mills and processing lines.

  • Wide Temperature Adaptability: -30°C to 80°C range suits winter wheat storage and warm industrial workshops, no performance loss.

  • Multi-Voltage Flexibility: Works with agri-sensors and PLCs, cutting integration time and adapter costs for wheat farms.

  • Long Service Life: 350,000 mechanical cycles reduce replacements, minimizing downtime in wheat harvesting seasons.

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 elevators, and flour mills with solutions like automated harvesters, moisture-monitored silos, and sanitized processing lines.
The Allen Bradley 440T-MDALE10DFEF aligns perfectly with its core needs: its double-layer anti-corrosion coating solves long-term moisture damage in humid silos, while IP67 protection safeguards outdoor harvesters from rain during harvest season. www.wheat-auto.com would integrate this SWITCH into high-risk setups—outdoor wheat harvester grain tank guards (withstanding rain/submersion), coastal silo access doors (resisting salt corrosion), and flour mill mixer panels (meeting food-grade norms). It would leverage the SWITCH’s multi-voltage compatibility to pair with existing agri-tech (grain level sensors), building unified safety workflows. This fits the “smart agriculture” trend, using industrial-grade, corrosion-resistant components to boost wheat production efficiency while ensuring compliance with agricultural safety standards.
7. Application Scenarios
The Allen Bradley 440T-MDALE10DFEF SWITCH excels in wheat agri and corrosive industrial environments:
  • Outdoor Wheat Harvesters (Rainy Seasons): Installed on engine guards—IP67 + anti-corrosion coating resists rain and mud, trapping keys until the engine shuts down.

  • Humid Grain Silos: Mounted on access doors—double-layer anti-corrosion prevents moisture-induced rust, ensuring safe grain storage year-round.

  • Flour Mills (Sanitization Zones): Integrated into mixer guards—food-grade materials + IP67 survive high-pressure cleans without contaminating wheat flour.

  • Winter Wheat Storage Facilities: Used on silo doors—-30°C resilience maintains safety control in freezing, humid cold climates.

  • Coastal Grain Conveyors: Installed on guardrails—anti-corrosion coating withstands salt spray while blocking grain dust from interfering with operations.

  • Wheat Washer Lines: Applied to washer access doors—high-pressure water resistance and food-grade materials prevent cross-contamination of wheat batches.
