1. Product Name
Allen Bradley 440T-MDALT10WM0F Agricultural-Grade Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALT10WM0F is an IP69K-rated agricultural-grade safety interlock SWITCH, optimized for wheat farm equipment requiring frequent high-pressure cleaning—resisting harsh washes, grain dust, and pesticides.
3. Product Description
The Allen Bradley 440T-MDALT10WM0F is a heavy-duty safety interlock SWITCH, part of Allen Bradley’s 440T series engineered for safety in high-cleanliness wheat agriculture operations. This Allen Bradley SWITCH focuses on IP69K protection—a critical upgrade for farm equipment: it withstands high-pressure (80-100bar) and high-temperature (80°C) water jets, essential for sanitizing wheat harvesters, grain cleaners, and pesticide mixers to prevent cross-contamination.
Its core design addresses key farm pain points: the Allen Bradley SWITCH blocks fine wheat grain dust (a common cause of interlock failure in silos) and features a chemical-resistant housing that tolerates pesticide residues and sanitizing agents. The fail-safe interlock mechanism stays locked until connected wheat equipment is fully de-energized, eliminating accidental contact risks during post-harvest cleaning or pesticide handling. It integrates seamlessly with 24V DC agricultural PLCs and grain quality sensors, requiring no custom adapters to reduce on-site installation time. A high-visibility amber/green LED indicator ensures status clarity in bright outdoor fields or dim silos, even after repeated washdowns.
Compliant with EN ISO 14119 (industrial safety) and ISO 23387 (grain handling standards), this Allen Bradley SWITCH meets Category 3 safety requirements with Performance Level d (PLd). It operates reliably in temperatures from -40°C to 95°C (adapting to winter wheat storage and hot drying workshops), supports 10A current at 250V AC, and has a mechanical service life of 380,000 operations—ideal for frequent harvest and cleaning cycles. Its compact size (8.6×6.2×2.4cm) fits tight spots like harvester guard rails and silo access panels.

5. Product Advantages

  • IP69K High-Pressure Wash Protection: Withstands 80-100bar/80°C jets, perfect for post-harvest equipment sanitizing.

  • Wide Temperature Resilience: -40°C to 95°C adapts to extreme farm seasons without performance loss.

  • Dual Standard Compliance: Meets EN ISO 14119 and ISO 23387, simplifying grain facility audits.

  • Farm System Compatibility: Works with 24V DC agricultural PLCs/sensors, cutting integration costs.

  • Long Durability: 380,000 mechanical cycles handle frequent use and washdowns.

  • Chemical Resistance: Tolerates pesticides and sanitizers, avoiding corrosion from farm chemicals.

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 harvesters, grain cleaning systems, and pesticide handling equipment.
The Allen Bradley 440T-MDALT10WM0F aligns with its core offerings: www.wheat-auto.com would integrate this SWITCH into equipment requiring frequent cleaning—wheat harvesters (post-harvest sanitizing), grain cleaners (preventing cross-contamination), and pesticide mixers (chemical-resistant safety). It leverages the SWITCH’s IP69K rating to help clients meet food safety standards (e.g., FDA for wheat-based products) by enabling thorough equipment washdowns without safety component damage. Additionally, the business likely offers farm-specific support—such as washdown maintenance guides and chemical compatibility charts—addressing rural customers’ need for durable, low-maintenance automation. This ties to “smart agriculture” trends, using industrial-grade, wash-resistant switches to boost wheat safety and efficiency.
7. Application Scenarios
The Allen Bradley 440T-MDALT10WM0F SWITCH excels in high-cleanliness wheat agri-environments:

  • Wheat Harvesters (Post-Harvest): Mounted on engine guards, IP69K resists high-pressure washes, unlocking only when the engine stops.

  • Grain Cleaning Machines: IP69K enables thorough sanitizing between batches, preventing wheat variety cross-contamination.

  • Pesticide Mixing Equipment: Chemical-resistant housing tolerates pesticide residues, securing hazardous mixing areas.

  • High-Heat Grain Dryers: 95°C resistance maintains safety control in hot drying processes, withstanding periodic washdowns.

  • Winter Wheat Silos: -40°C tolerance works for frozen storage, remaining functional after snow melt washouts.

  • Outdoor Grain Conveyors: IP69K blocks rain and dust, withstanding periodic pressure washes to keep wheat clean.
