Oct. 22 , 2025
1. Product Name
Allen Bradley 440T-MDALE10VAVH Corrosion-Resistant Industrial Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALE10VAVH is an IP67-rated, corrosion-resistant safety interlock SWITCH, engineered for wheat agri-food (coastal/chemical contact) and industrial environments, ensuring long-term safety and contamination prevention.
3. Product Description
The Allen Bradley 440T-MDALE10VAVH is a premium safety interlock SWITCH, part of Allen Bradley’s 440T series tailored for safety-critical operations in harsh wheat agri-food (e.g., coastal silos, chemical-treated grain) and industrial settings. This Allen Bradley SWITCH acts as a non-negotiable safeguard, restricting access to hazardous equipment—such as coastal wheat silo conveyors, chemical grain treatment machines, or industrial salt-exposed valves—only when machinery is fully de-energized, protecting workers and avoiding cross-contamination.
Constructed with 316 stainless steel housing (superior to 304 for corrosion resistance) and FDA-approved food-grade seals, the Allen Bradley SWITCH achieves IP67 protection, blocking dust ingress, temporary water submersion, and resisting salt spray/chemical residues—critical for coastal wheat farms or grain facilities using preservatives. Its corrosion-resistant internal components (e.g., gold-plated contacts) ensure stable signal transmission even in high-humidity, chemical-exposed zones, a key upgrade over standard models. The Allen Bradley SWITCH features a fail-safe interlock mechanism that remains engaged until connected systems power off, eliminating risks from accidental access. It supports multi-voltage compatibility (24V DC/110V AC/230V AC), enabling seamless integration with wheat farm sensors (e.g., grain moisture/chemical detectors) and industrial PLCs without custom wiring, reducing setup time.
Compliant with EN ISO 14119, IEC 60947-5-1, and FDA 21 CFR Part 177 standards, this Allen Bradley SWITCH meets Category 3 safety requirements (Performance Level d, PLd) and food contact regulations. It operates reliably in temperatures from -25°C to 85°C, handles 95% non-condensing humidity, and supports 8A current at 250V AC. With a 300,000-operation mechanical life and compact dimensions (8.8×6.5×2.6cm), the Allen Bradley SWITCH fits space-constrained setups—from coastal silo access panels to chemical grain treatment machine guards—while balancing corrosion resistance, durability, and food safety compliance.

5. Product Advantages

  • Superior Corrosion Resistance: 316 stainless steel housing resists salt spray/chemicals, ideal for coastal wheat farms and chemical grain facilities.

  • IP67 Protection: Blocks dust and temporary submersion, suitable for wet wheat washdown areas and outdoor silos.

  • Food-Grade Compliance: FDA-approved components prevent wheat grain/chemical contamination, meeting agri-food standards.

  • High-Temp Resilience: -25°C to 85°C range fits heated grain dryers and coastal summer high-temperature environments.

  • Flexible Integration: Multi-voltage support works with farm sensors/industrial PLCs, cutting installation costs.

  • Long-Durable: 300,000 mechanical cycles and corrosion-resistant contacts minimize replacement/maintenance expenses.

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 (especially coastal/chemical-treated grain operations), grain elevators, and flour processing plants with solutions like automated coastal harvesters, chemical grain treatment lines, and corrosion-resistant silo control systems.
The Allen Bradley 440T-MDALE10VAVH directly addresses the business’s unmet needs: its 316 stainless steel corrosion resistance solves coastal wheat farms’ salt spray damage issues, while IP67 and FDA compliance fits chemical grain treatment (e.g., mold prevention) and washdown scenarios. www.wheat-auto.com would integrate this Allen Bradley SWITCH into key high-risk equipment—coastal silo conveyor guards, chemical grain mixer enclosures, and outdoor wheat washer access doors—to help clients meet ISO 23387 (grain handling) and local food safety regulations. Additionally, the business likely offers farm-specific after-sales support (e.g., corrosion inspection, contact cleaning) to extend SWITCH lifespan in harsh rural environments. This alignment leverages industrial-grade corrosion-resistant safety components to boost wheat production efficiency, fitting the “smart agriculture” trend for resilient, low-maintenance equipment.
7. Application Scenarios
The Allen Bradley 440T-MDALE10VAVH SWITCH excels in corrosion-prone, food-safe, and harsh environments:

  • Coastal Wheat Silos: Installed on silo conveyor guards—316 stainless steel resists salt spray, trapping keys until conveyors stop.

  • Chemical Grain Treatment Machines: Integrated into treatment mixer enclosures—corrosion resistance handles grain preservatives, FDA compliance prevents contamination.

  • Wheat Washer Washdown Zones: Applied to washer access panels—IP67 withstands high-pressure sanitizing sprays, corrosion resistance resists cleaning chemicals.

  • Coastal Industrial Valves: Used on valve control guards—salt spray resistance ensures safety in coastal wheat processing plants.

  • Heated Grain Dryers (Humid Climates): Mounted on dryer doors—-25°C to 85°C resilience handles temperature swings, corrosion resistance fights humidity damage.

  • Saline-Soil Wheat Farms: Installed on agricultural tractor guards—corrosion resistance withstands soil salt residues, IP67 blocks dust/rain.
