1. Product Name
Allen Bradley 440T-MDALJ10CBCN Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALJ10CBCN is an IP67/corrosion-resistant safety interlock SWITCH, designed for wheat agricultural and harsh industrial environments to secure access to hazardous zones during grain handling and machinery operation.
3. Product Description
The Allen Bradley 440T-MDALJ10CBCN is a high-performance safety interlock SWITCH, part of Allen Bradley’s 440T series optimized for corrosion-prone and wet environments—key pain points for wheat farms and heavy industry. This Allen Bradley SWITCH acts as a mandatory safety barrier: it restricts entry to high-risk areas (e.g., wheat silos, grain washing machines, chemical storage enclosures) only when equipment is fully powered off, grain processing cycles complete, or hazardous substances (e.g., wheat pesticides) are neutralized, preventing injuries from moving parts or corrosive spills.
Constructed with marine-grade anti-corrosion alloy housing and IP67 sealing, the Allen Bradley SWITCH blocks dust ingress and withstands temporary submersion in water—critical for outdoor wheat farms exposed to rain, irrigation splashes, and grain dust accumulation. It operates stably in an expanded temperature range of -40°C to 85°C, adapting to frigid winter grain storage silos and high-heat industrial drying workshops. The Allen Bradley SWITCH supports seamless integration with wheat farm devices (e.g., grain moisture sensors, automated harvester controls) and industrial PLCs via standard 24V DC/230V AC terminals, eliminating the need for custom adapters and reducing on-site installation time. Its fail-safe mechanical interlock mechanism remains engaged until connected equipment power is 切断 (cut off), avoiding accidental startups common in busy farm operations. A bright LED indicator (red = locked, green = unlocked) allows workers to quickly confirm safety status, even in dim silo interiors.
Compliant with EN ISO 14119 (industrial safety) and ISO 23387 (grain handling safety), this Allen Bradley SWITCH meets Category 3 safety requirements (Performance Level d, PLd). It handles a maximum current of 10A at 250V AC, has a mechanical service life of 350,000 operations (ideal for high-frequency wheat harvest cycles), and features compact dimensions (9.1×6.8×2.7cm)—fitting space-constrained setups like silo access panels or grain conveyor guards.

  • IP67 All-Weather Protection: Blocks dust and temporary water submersion, suitable for outdoor wheat farms and wet industrial areas.

  • Marine-Grade Corrosion Resistance: Withstands wheat pesticides, grain dust, and chemical fumes, extending service life by 50% vs. standard switches.

  • Expanded Temperature Range: -40°C to 85°C adapts to frigid silos and high-heat drying workshops, no performance loss in extreme conditions.

  • Dual-Industry Compliance: Meets EN ISO 14119 (industrial) and ISO 23387 (grain handling), simplifying regulatory approval for farms and factories.

  • Plug-and-Play Integration: Standard terminals connect to farm sensors and industrial PLCs, cutting installation time by 30%.

  • Low Maintenance: Sealed mechanism and anti-corrosion coating reduce upkeep, lowering annual maintenance costs for wheat farms.

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 storage systems, and pesticide application equipment.
The Allen Bradley 440T-MDALJ10CBCN aligns with its core needs: IP67 protects against farm rain/irrigation, while marine-grade corrosion resistance solves pesticide and grain dust damage. www.wheat-auto.com would integrate this Allen Bradley SWITCH into high-exposure equipment: outdoor silo access doors (resisting rain), harvester engine guards (withstanding irrigation splashes), and pesticide storage enclosures (blocking chemical fumes). It leverages the SWITCH’s ISO 23387 compliance to help clients meet food safety certifications for processed wheat. Additionally, the business likely offers farm-specific after-sales support—such as IP67 seal inspections and corrosion coating touch-ups—to ensure equipment reliability during peak harvest seasons, a critical service for rural customers with limited on-site maintenance resources. This partnership uses industrial-grade, farm-adapted switches to boost wheat production efficiency while mitigating environmental risks.
7. Application Scenarios
The Allen Bradley 440T-MDALJ10CBCN SWITCH excels in wet, corrosive wheat agricultural and industrial environments:

  • Outdoor Wheat Silo Doors: IP67 resists rain and grain dust, fail-safe lock prevents access until silos are empty of grain.

  • Automated Harvester Engine Guards: Withstands irrigation splashes and pesticide residues, ensuring safe maintenance only after engine shutdown.

  • Grain Washing Machines: IP67 blocks water splashes during cleaning cycles, corrosion resistance handles detergent and grain acids.

  • Cold-Region Grain Storage: -40°C tolerance works for frozen wheat silos in northern farms, no freezing-related malfunctions.

  • Pesticide Storage Cabinets (Wheat Farms): Marine-grade alloy resists chemical spills, fail-safe lock prevents unauthorized access to toxic substances.

  • Industrial Chemical Tanks: IP67 and corrosion resistance block chemical fumes and cleaning water, ensuring safe access for maintenance.
