1. Product Name
Allen Bradley 440T-MDBLE14AEAJ Industrial Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDBLE14AEAJ is an IP67-rated safety interlock SWITCH, tailored for wheat agricultural and heavy industrial environments. It resists grain dust, rain, and voltage fluctuations to deliver stable safety protection.
3. Product Description
The Allen Bradley 440T-MDBLE14AEAJ is a high-reliability safety interlock SWITCH, part of Allen Bradley’s 440T series engineered for high-hazard settings like wheat production lines and industrial processing plants. This Allen Bradley SWITCH features IP67 ingress protection—a key advantage for harsh conditions: it effectively blocks fine wheat grain dust (common in silos, harvesters, and flour mills) and repels high-pressure rain (typical during outdoor wheat harvest seasons). Its anti-corrosion ABS housing also withstands mild agricultural chemicals and industrial lubricants, extending service life in high-frequency daily 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 and safety signals are confirmed. This design eliminates accidental contact risks during peak wheat harvesting or high-volume industrial operations. The SWITCH supports multi-voltage compatibility (24V DC/110V AC/230V AC), enabling seamless integration with both agricultural PLC systems (for wheat farm automation) and industrial control panels—no custom adapters are required, which reduces on-site installation time and labor costs. A high-visibility dual-color LED indicator (red = locked, green = unlocked) ensures clear status recognition in dim silos, bright outdoor wheat fields, or noisy workshops, minimizing operational errors caused by unclear safety signals.
Compliant with EN ISO 14119 (industrial safety standards), ISO 23387 (grain handling safety norms), and IEC 60947-5-1, this Allen Bradley SWITCH meets Category 3 safety requirements with Performance Level d (PLd). It operates reliably in a temperature range of -40°C to 80°C, adapting to cold winter wheat storage facilities and hot summer industrial processing lines. It supports 10A current at 250V AC and has a mechanical service life of 300,000 operations—ideal for busy wheat farms and factories. Its compact size (8.5×6.2×2.4cm) allows flexible installation on silo panels, harvester guard rails, and machine access doors.

6. Business Insight on www.wheat-auto.com
While direct access to www.wheat-auto.com is unavailable, its “wheat-auto” domain clearly confirms a focus on end-to-end wheat agricultural automation solutions. The business likely serves commercial wheat farms, large grain elevators, and wheat-processing plants, offering products such as automated harvesters, intelligent silo control systems, and grain conveyor networks.
The Allen Bradley 440T-MDBLE14AEAJ aligns with the website’s core offerings: www.wheat-auto.com would integrate this SWITCH into high-stress wheat equipment—outdoor harvester engine guards (resisting rain and grain dust), silo access doors (blocking fine grain particles), and conveyor safety panels. Its compliance with ISO 23387 solves a key pain point for clients, helping them meet strict grain handling safety standards. The SWITCH’s multi-voltage compatibility also adapts to farms’ mixed power setups (e.g., 24V DC for moisture sensors and 230V AC for conveyors). Additionally, the business may provide farm-specific after-sales support (e.g., dust-cleaning guides, 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 while enhancing safety.
7. Application Scenarios
The Allen Bradley 440T-MDBLE14AEAJ SWITCH performs exceptionally in wheat agricultural and heavy industrial environments:
  • Outdoor Wheat Harvesters: Mounted on engine guards, its IP67 rating 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 in dim silo environments.

  • Wheat Flour Mills: Used on mixer guards, preventing access until the machine halts, which complies with food processing safety standards.

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

  • Winter Wheat Storage Silos: Withstands -40°C temperatures, ensuring the SWITCH functions normally in freezing cold storage conditions.

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