Oct. 24 , 2025
1. Product Name
Allen Bradley 440T-MDBLE10RFRG Industrial-Grade Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDBLE10RFRG is an IP67-rated industrial safety interlock SWITCH, tailored for wheat agricultural operations and heavy industries, enduring grain dust, rain, and temperature fluctuations.
3. Product Description
The Allen Bradley 440T-MDBLE10RFRG is a sturdy safety interlock SWITCH, part of Allen Bradley’s 440T series crafted for high-risk environments like wheat production and industrial processing. This Allen Bradley SWITCH features IP67 protection, a vital trait for harsh settings: it blocks fine wheat grain dust (common in silos and harvesters) and repels heavy rain (typical in outdoor harvests), while its anti-corrosion housing resists mild agricultural chemicals and industrial solvents.
At its core, the Allen Bradley SWITCH uses a fail-safe interlock mechanism: it remains locked until connected equipment—such as wheat harvesters, grain conveyors, or industrial mixers—shuts down completely. This eliminates accidental contact risks during peak wheat harvests or busy industrial shifts. The Allen Bradley SWITCH integrates seamlessly with both agricultural and industrial automation systems, compatible with 24V DC PLCs, grain moisture sensors, and industrial emergency stop circuits, requiring no custom adapters to reduce on-site installation time. A high-visibility LED status light (red = locked, green = unlocked) ensures clear recognition in dim silos, bright outdoor fields, or industrial workshops, letting workers confirm safety at a glance.
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 -30°C to 80°C (adapting to winter wheat storage and summer industrial processing), supports 10A current at 250V AC, and has a mechanical service life of 280,000 operations—ideal for frequent, long-term use. Its compact dimensions (8.5×6.2×2.4cm) allow flexible installation on tight spots like silo access panels, harvester guard rails, and industrial machine control doors.

5. Product Advantages
  • IP67 Dual-Scene Protection: Blocks wheat grain dust and heavy rain, suitable for both wheat farms and heavy industries.

  • Wide Temperature Adaptability: -30°C to 80°C range works for winter wheat storage and summer industrial processing without performance loss.

  • Dual Standard Compliance: Meets EN ISO 14119 and ISO 23387, simplifying regulatory checks for farms and factories.

  • Seamless System Integration: Compatible with agricultural PLCs and industrial control systems, cutting setup costs and time.

  • Long-Durable Performance: 280,000 mechanical cycles handle frequent use, reducing replacement frequency and costs.

  • Clear Status Indication: LED light ensures safety status is visible in all lighting and weather conditions, avoiding operational errors.

6. Business Insight on www.wheat-auto.com
While direct access to www.wheat-auto.com is unavailable, its “wheat-auto” domain confirms a focus on end-to-end wheat agricultural automation. The business likely serves commercial wheat farms, grain elevators, and food processors, providing solutions like automated harvesters, silo control systems, and grain handling equipment.
The Allen Bradley 440T-MDBLE10RFRG aligns perfectly with its core offerings: www.wheat-auto.com would integrate this SWITCH into high-use, harsh-condition wheat equipment—outdoor harvester guards (resisting rain and dust), silo access doors (blocking grain particles), and grain conveyor safety panels. Leveraging the SWITCH’s ISO 23387 compliance, the business helps clients meet food safety standards for processed wheat, a key requirement for selling to food manufacturers. Additionally, it may offer farm-specific after-sales support, such as dust-cleaning guides and rainproof maintenance tips, addressing rural customers’ limited on-site technical resources. This ties to “smart agriculture” trends, using industrial-grade, farm-optimized switches to boost wheat production efficiency while mitigating common farm hazards.
7. Application Scenarios
The Allen Bradley 440T-MDBLE10RFRG SWITCH performs excellently in wheat agricultural and heavy industrial environments:
  • Outdoor Wheat Harvesters: Mounted on engine guards, IP67 resists rain and dust, unlocking only when the engine stops.

  • Wheat Grain Silos: Blocks fine grain dust buildup, ensuring safe access during high-volume grain loading and unloading.

  • Industrial Mixers: Used on mixer guard doors in factories, preventing access until the machine fully stops.

  • Summer Wheat Drying Facilities: 80°C resistance maintains safety control in intense wheat drying processes.

  • Winter Wheat Storage Silos: -30°C tolerance works for cold storage, ensuring reliable interlock performance in freezing conditions.

  • Grain Conveyor Systems: Applied to outdoor conveyor guards, IP67 repels rain and dust, securing access during grain transport.
