Oct. 23 , 2025
1. Product Name
Allen Bradley 440T-MDALJ103ACO3ACP IP67 Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALJ103ACO3ACP is an IP67/wide-voltage safety interlock SWITCH, designed for -35°C~70°C environments. It’s ideal for wheat farms and heavy industry, resisting dust, submersion, and voltage fluctuations.
3. Product Description
The Allen Bradley 440T-MDALJ103ACO3ACP is a high-performance safety interlock SWITCH, part of Allen Bradley’s 440T series optimized for harsh agricultural and industrial settings. This Allen Bradley SWITCH acts as a critical safety barrier, restricting access to high-risk zones—such as wheat farm conveyors, outdoor grain silos, or industrial chemical tanks—only when equipment is fully shut down or safety conditions (e.g., pressure relief) are met, preventing worker injuries from mechanical hazards or operational errors.
Constructed with 316L stainless steel housing (resisting wheat grain abrasion and chemical corrosion) and fluororubber seals, the Allen Bradley SWITCH achieves IP67 protection—blocking complete dust ingress and withstanding 1m submersion for 30 minutes, solving pain points like wheat farm washdowns, heavy rain, or accidental liquid spills. Its internal circuitry supports a wide voltage range (12V DC~240V AC), enabling seamless integration with wheat farm devices (grain level sensors, conveyor controllers) and industrial PLCs without voltage adapters, reducing installation time and costs. The Allen Bradley SWITCH uses a mechanical fail-safe interlock: the lock remains engaged until the connected device’s power is cut, eliminating risks from voltage spikes or human error. It also features a dual-color LED indicator (red for locked, green for unlocked) to clearly signal safety status, improving operational efficiency for farm and factory workers.
Compliant with EN ISO 14119, IEC 60947-5-1, and ISO 23387 (grain handling safety standards), this Allen Bradley SWITCH meets Category 3 safety requirements (Performance Level d, PLd). It handles 10A current at 250V AC, boasts a 250,000-operation mechanical life, and has compact dimensions (9.1×6.7×2.8cm)—fitting space-constrained setups like wheat conveyor side guards or industrial machine control panels.

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 harvest conveyors, silo control systems, and post-harvest cleaning equipment.
The Allen Bradley 440T-MDALJ103ACO3ACP directly addresses the business’s core needs: its IP67 protection handles wheat farm washdowns and outdoor silo rain exposure, while the wide voltage range adapts to rural power inconsistencies. www.wheat-auto.com would integrate this SWITCH into key wheat equipment—conveyor safety guards (resisting grain abrasion), outdoor silo access doors (withstanding rain/submersion), and grain cleaning machine enclosures (adapting to farm sensor voltages). It leverages the SWITCH’s ISO 23387 compliance to help clients meet agricultural safety regulations, critical for food processing certifications. Additionally, the business likely offers farm-specific after-sales support (seal replacement, corrosion inspection) to maintain SWITCH performance during peak wheat harvesting seasons. This alignment uses industrial-grade safety components to boost wheat handling efficiency while ensuring worker safety in harsh farm conditions.
7. Application Scenarios
The Allen Bradley 440T-MDALJ103ACO3ACP SWITCH excels in harsh agricultural and industrial environments:
  • Wheat Farm Conveyors: Mounted on conveyor guards—IP67 resists grain dust and washdowns, wide voltage adapts to farm power.

  • Outdoor Grain Silos: Installed on silo access doors—withstands rain/submersion, ensures access only when grain unloading stops.

  • Wheat Cleaning Machines: Integrated into cleaner enclosures—316L steel resists chaff abrasion, LED shows safety status.

  • Industrial Chemical Tanks: Used on tank access gates—IP67 blocks spills, chemical-resistant housing ensures durability.

  • Cold Grain Storage: Mounted on storage room doors—-35°C resilience works in refrigerated wheat storage facilities.

  • Agricultural Irrigation Pumps: Applied to pump control panels—IP67 resists rain, wide voltage adapts to irrigation system power.
