Oct. 23 , 2025
1. Product Name
Allen Bradley 440T-MDALS103DCJ3DCK Dual-Coils Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALS103DCJ3DCK is an IP67/dual DC coils safety interlock SWITCH, customized for wheat agricultural and grain-processing scenarios, delivering double safety triggers against chemical corrosion and moisture.
3. Product Description
The Allen Bradley 440T-MDALS103DCJ3DCK is a high-performance safety interlock SWITCH, part of Allen Bradley’s 440T series engineered to solve high-risk safety challenges in wheat farms and grain-handling facilities. This Allen Bradley SWITCH acts as a dual-security barrier: its unique dual DC coils design requires two independent safety signals (e.g., equipment shutdown + chemical seal confirmation) to release the interlock, strictly restricting access to hazardous zones like wheat pesticide storage rooms, coastal grain silos, and high-moisture cleaning lines—effectively eliminating single-point failure risks.
Constructed with corrosion-resistant 316 stainless steel housing and IP67 sealing, the Allen Bradley SWITCH withstands mild wheat pesticide residues (common in pest control) and coastal salt spray, while blocking fine grain dust and splashing water during cleaning. It operates stably in a temperature range of -40°C to 85°C, adapting to frozen winter wheat storage and high-heat grain-drying workshops without performance loss. The Allen Bradley SWITCH integrates seamlessly with wheat farm equipment (e.g., automated harvesters, grain moisture sensors) and industrial PLCs via standard 24V DC terminals, avoiding custom adapters and cutting on-site installation time by 30%. A high-visibility LED indicator (red = locked, green = unlocked) ensures clear status checks in dim silos or bright outdoor harvest fields, and its fail-safe mechanism remains engaged until both DC coils receive valid safety signals—preventing accidental startups in busy farm operations.
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, boasts a mechanical service life of 350,000 operations (ideal for high-frequency wheat harvest cycles), and has compact dimensions (9.2×6.8×2.7cm)—fitting space-constrained setups like silo access panels or conveyor guard rails.

5. Product Advantages

  • Dual DC Coils Safety: Requires two independent signals to unlock, eliminating single-point failures in high-risk wheat farm zones (e.g., pesticide storage).

  • IP67 & Corrosion Resistance: 316 stainless steel resists pesticides/salt spray; IP67 blocks dust/water, perfect for harsh grain environments.

  • Extreme Temperature Adaptability: -40°C to 85°C range works for frozen wheat storage and hot drying workshops without malfunctions.

  • Dual-Industry Compliance: Meets EN ISO 14119 and ISO 23387, simplifying regulatory approval for farms and grain facilities.

  • Seamless Integration: Standard 24V DC terminals connect to farm devices/PLCs, reducing installation complexity and costs.

  • Long-Lasting Durability: 350,000-cycle mechanical life and anti-wear components lower maintenance expenses for wheat operations.

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, large grain elevators, and food processors with solutions like automated harvesters, coastal-region grain storage systems, and pesticide management setups.
The Allen Bradley 440T-MDALS103DCJ3DCK aligns with its core pain points: high-risk zones (e.g., pesticide storage) needing double safety (solved by dual DC coils) and corrosion from chemicals/salt spray (addressed by 316 stainless steel + IP67). www.wheat-auto.com would integrate this Allen Bradley SWITCH into critical equipment: pesticide storage unit doors (requiring both “container sealed” and “power off” signals to unlock), coastal grain silo access panels (withstanding salt spray), and high-moisture grain cleaning lines (blocking splashes). 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 dual-coils calibration guides and pesticide residue cleaning tips—to address rural customers’ limited on-site maintenance resources. This partnership uses industrial-grade, farm-adapted switches to boost wheat production efficiency while mitigating high-risk safety hazards.
7. Application Scenarios
The Allen Bradley 440T-MDALS103DCJ3DCK SWITCH excels in high-risk wheat agricultural and grain-industrial environments:

  • Wheat Pesticide Storage Units: Dual DC coils require “container sealed” + “power off” signals to unlock, preventing chemical exposure risks.

  • Coastal Wheat Grain Silos: 316 stainless steel resists salt spray; IP67 blocks dust, securing silo access during loading/unloading.

  • Grain Drying Workshops: 85°C heat resistance handles warm drying processes, avoiding interlock performance drops.

  • Frozen Wheat Storage (Cold Regions): -40°C tolerance works for winter silos, maintaining dual-coils safety control in freezing conditions.

  • Wet Grain Cleaning Lines: IP67 resists splashing water, ensuring safe maintenance during wheat washing operations.

  • Automated Wheat Harvesters (Coastal Farms): Mounted on engine guards, resists salt spray and dust, with dual coils adding harvest safety.
