Oct. 22 , 2025
1. Product Name
Allen Bradley 440T-MDALE11YFYG Chemical-Resistant Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALE11YFYG is an IP68/chemical-resistant safety interlock SWITCH, optimized for -40°C~95°C environments—ideal for wheat chemical treatment systems and industrial chemical zones, ensuring safety control against corrosives and deep moisture.
3. Product Description
The Allen Bradley 440T-MDALE11YFYG is a premium chemical-resistant safety interlock SWITCH, part of Allen Bradley’s 440T series engineered for safety-critical operations in corrosive, high-moisture settings. This Allen Bradley SWITCH acts as a robust barrier, restricting access to high-risk equipment—such as wheat farm chemical treatment machines, pesticide storage tanks, or industrial chemical reactors—only when systems are depressurized, chemical residues neutralized, or fully shut down, protecting workers from toxic exposure and equipment corrosion.
Constructed with Hastelloy alloy housing (resists wheat treatment chemicals like organophosphates, chlorine-based disinfectants, and industrial acids) and FKM fluoroelastomer seals, the Allen Bradley SWITCH achieves IP68 protection—blocking permanent dust ingress and 1.5m water submersion for 24 hours, solving pain points like post-chemical-treatment washdowns and accidental liquid spills. Its internal components use gold-plated contacts (anti-corrosion, stable signal transmission) and PTFE insulators (resistant to 95°C heat and chemical erosion), ensuring reliability in humid, corrosive wheat processing facilities (98% non-condensing humidity). The Allen Bradley SWITCH integrates a fail-safe interlock mechanism: the lock remains engaged until connected systems complete chemical neutralization (via pH sensor integration) or shut down, eliminating accidental access during chemical transfer. It supports wide voltage compatibility (12V DC~240V AC), enabling seamless integration with wheat farm chemical sensors (pH detectors, chemical level monitors) and industrial PLCs without voltage converters, reducing setup time by 25%.
Compliant with EN ISO 14119, IEC 60947-5-1, and FDA 21 CFR Part 177 (food-contact safe), this Allen Bradley SWITCH meets Category 3 safety requirements (Performance Level d, PLd) and suits wheat zones where chemical safety is critical. It handles 10A current at 250V AC, boasts a 400,000-operation mechanical life, and has compact dimensions (8.6×6.3×2.5cm)—fitting space-constrained setups like wheat chemical sprayer guards or narrow industrial chemical tank access panels.

5. Product Advantages

  • Superior Chemical Resistance: Hastelloy housing resists wheat pesticides, disinfectants, and industrial acids—no corrosion-induced failure.

  • IP68 Top-Tier Protection: 1.5m/24h water submersion + dust-tight design, ideal for post-chemical washdowns and wet storage.

  • Wide Temp Adaptability: -40°C~95°C range suits wheat winter chemical storage (-40°C) and summer treatment (95°C heat).

  • Food-Safe Compliance: FDA approval ensures no chemical leaching, safe for wheat contact after treatment.

  • Reliable Safety Logic: pH-sensor integrated lock release + PLd rating, preventing toxic exposure.

  • Long Durability: Gold-plated contacts + 400,000 cycles reduce maintenance and replacement costs.

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 food processors with solutions like automated chemical treatment systems, pesticide application machinery, and post-treatment grain drying lines.
The Allen Bradley 440T-MDALE11YFYG solves the business’s key challenge: safety control in wheat chemical processes (e.g., pesticide spraying, grain mold disinfection). www.wheat-auto.com would integrate this SWITCH into core chemical equipment—wheat sprayer access guards (resisting pesticide corrosion), chemical storage tank doors (IP68 for spill protection), and post-treatment conveyor guards (FDA-safe for treated wheat). It leverages the SWITCH’s compliance with ISO 23387 (grain handling safety) to help clients meet agricultural chemical regulations, while wide voltage compatibility simplifies integration with farm’s chemical sensor networks. Additionally, the business likely offers chemical-specific after-sales support (corrosion inspection, seal replacement post-chemical season) to address rural farm needs. This alignment with “smart agriculture” uses industrial-grade chemical-resistant components to boost wheat treatment efficiency and worker safety.
7. Application Scenarios
The Allen Bradley 440T-MDALE11YFYG SWITCH excels in corrosive, high-moisture environments:

  • Wheat Pesticide Sprayers: Mounted on sprayer tank guards—resists pesticide corrosion, IP68 handles rain during outdoor spraying.

  • Grain Disinfection Tanks: Installed on tank access doors—chemical resistance withstands chlorine disinfectants, lock releases post-neutralization.

  • Industrial Acid Tanks: Used on acid storage guards—Hastelloy housing resists acid spills, IP68 prevents leak damage.

  • Food-Grade Wheat Washers: Integrated into washer guards—FDA compliance ensures safe wheat contact, IP68 handles high-pressure washdowns.

  • Aquaculture Wheat Feed Mixers: Applied to mixer guards—resists saltwater corrosion (aquafeed production), IP68 for wet environments.

  • Pharmaceutical Wheat Extractors: Mounted on extractor guards—chemical resistance withstands solvents, FDA compliance meets pharmaceutical standards.
