Oct. 24 , 2025
1. Product Name
Allen Bradley 440T-MDBLE130R0R Industrial Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDBLE130R0R is an IP67-rated safety interlock SWITCH, tailored for wheat agricultural and heavy industrial environments, withstanding grain dust, rain, and voltage variations for stable safety control.
3. Product Description
The Allen Bradley 440T-MDBLE130R0R is a high-performance safety interlock SWITCH, part of Allen Bradley’s 440T series engineered for high-hazard settings like wheat production and industrial processing. This Allen Bradley SWITCH features IP67 protection, a key advantage for harsh conditions: it blocks fine wheat grain dust (common in silos and harvesters) and repels high-pressure rain (typical of outdoor wheat harvests), while its anti-corrosion housing resists mild agricultural chemicals and industrial oils—extending service life in demanding use.
At its core, the Allen Bradley SWITCH adopts a fail-safe interlock mechanism: it remains locked until connected equipment (e.g., wheat harvesters, grain conveyors, industrial mixers) fully shuts down, eliminating accidental contact risks during peak wheat harvests or high-volume industrial production. Another critical feature is its multi-voltage compatibility (24V DC/110V AC/230V AC), which allows seamless integration with both agricultural PLCs and industrial control systems—no custom adapters required, significantly reducing on-site installation time. A high-visibility LED indicator (red = locked, green = unlocked) ensures clear status recognition in dim silos, bright outdoor wheat fields, or busy industrial workshops, minimizing operational errors caused by unclear safety signals.
Compliant with EN ISO 14119 (industrial safety), ISO 23387 (grain handling safety), and IEC 60947-5-1, this Allen Bradley SWITCH meets Category 3 safety requirements with Performance Level d (PLd). It operates reliably in a wide temperature range from -40°C to 80°C, adapting to cold winter wheat storage facilities and hot summer industrial processing lines. The SWITCH supports 10A current at 250V AC and has a mechanical service life of 300,000 operations—ideal for frequent use in high-activity wheat farms and factories. Its compact dimensions (8.6×6.3×2.5cm) enable flexible installation on silo access panels, harvester guard rails, and machine control doors.

5. Product Advantages
  • IP67 Robust Protection: Shields against wheat grain dust and heavy rain, fitting indoor silos and outdoor agricultural equipment.

  • Multi-Voltage Flexibility: Works with 24V DC/110V AC/230V AC, adapting to mixed power systems in wheat farms and industries.

  • Wide Temperature Adaptability: -40°C to 80°C range handles winter wheat storage and summer industrial processing without performance loss.

  • Dual Compliance: Meets EN ISO 14119 and ISO 23387, simplifying regulatory checks for wheat-related and industrial operations.

  • Long-Term Durability: 300,000 mechanical cycles reduce replacement frequency, lowering long-term operational costs.

  • Clear Status Indication: LED light ensures safety status is visible in all environments, avoiding human error.

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 solutions. The business likely serves commercial wheat farms, large grain elevators, and wheat-processing food plants, offering products like automated harvesters, intelligent silo control systems, and grain conveyor networks.
The Allen Bradley 440T-MDBLE130R0R aligns perfectly with its core offerings: www.wheat-auto.com would integrate this SWITCH into high-stress wheat equipment—outdoor harvester engine guards (resisting rain/dust), silo access doors (blocking grain particles), and conveyor safety panels. Its ISO 23387 compliance solves a key pain point for wheat clients, helping them meet grain handling safety standards, while multi-voltage compatibility adapts to farms’ mixed power setups (24V DC for sensors, 230V AC for machinery). The business may also provide farm-specific after-sales support, such as dust-cleaning guides and voltage configuration tips, to address rural operational challenges. This positioning ties to global “smart agriculture” trends, using industrial-grade, farm-optimized switches like the Allen Bradley SWITCH to boost wheat production efficiency and safety.
7. Application Scenarios
The Allen Bradley 440T-MDBLE130R0R SWITCH excels in wheat agricultural and heavy industrial environments:
  • Outdoor Wheat Harvesters: Mounted on engine guards, IP67 resists rain and grain dust, unlocking only when the engine stops to protect workers during harvest.

  • Wheat Grain Silos: Blocks fine dust from stored wheat, ensuring safe access during high-volume loading/unloading operations.

  • Wheat Flour Processing Mixers: Used on mixer guards, preventing access until the machine halts completely, complying with food safety standards.

  • Summer Wheat Drying Facilities: 80°C temperature tolerance maintains reliable safety control in heat-based wheat drying processes.

  • Winter Wheat Storage Silos: -40°C resilience works for cold-climate storage, ensuring the SWITCH functions in freezing conditions.

  • Grain Conveyors (Wheat Farms): Multi-voltage compatibility fits 24V DC sensors and 230V AC conveyors, securing access during grain transport.
