Oct. 24 , 2025
1. Product Name
Allen Bradley 440T-MDBLE15ACAF Industrial Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDBLE15ACAF is an IP65-rated, durable safety interlock SWITCH, optimized for wheat agricultural and industrial environments. It resists grain dust, light moisture, and mild corrosion for stable safety performance.
3. Product Description
The Allen Bradley 440T-MDBLE15ACAF is a high-performance safety interlock SWITCH, part of Allen Bradley’s 440T series tailored for hazard-prone settings like wheat harvest lines, grain storage facilities, and mid-scale industrial plants. This Allen Bradley SWITCH boasts IP65 ingress protection—a key fit for wheat-related scenarios: it blocks fine grain dust (common in silo loading and wheat sorting) and repels light rain or washdown splashes (typical of outdoor farm operations or industrial cleaning). Its housing, made of anti-corrosion composite material, withstands mild agricultural chemicals (e.g., wheat pesticides) and industrial oils, avoiding premature degradation.
At its core, the Allen Bradley SWITCH adopts a fail-safe interlock design: it stays locked until connected equipment (such as wheat conveyors, small grain mills, or industrial pumps) fully shuts down and safety signals are verified. This eliminates accidental contact risks during busy wheat harvesting seasons or daily industrial shifts. The SWITCH supports multi-voltage compatibility (24V DC/110V AC), enabling seamless integration with wheat farms’ low-voltage sensor systems and industrial control panels—no custom adapters needed, cutting on-site installation time. A bright LED indicator (red = locked, green = unlocked) ensures clear status recognition in dim silos, sunny farm fields, or noisy workshops, reducing errors from unclear safety cues.
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 temperature range of -30°C to 70°C, adapts to 90% non-condensing humidity, supports 8A current at 250V AC, and has a mechanical service life of 250,000 operations. Its compact size (8.5×6.2×2.5cm) allows flexible installation on silo access panels, wheat harvester auxiliary guards, and small industrial machine doors.

5. Product Advantages
  • IP65 Protection: Blocks grain dust and light moisture, ideal for wheat farms and mid-scale industrial sites with non-intense washdowns.

  • Wide Temperature Range: -30°C to 70°C suits winter wheat storage and summer outdoor harvesting, adapting to seasonal farm changes.

  • Dual Standard Compliance: Meets industrial (EN ISO 14119) and grain handling (ISO 23387) norms, simplifying safety audits for farms/industries.

  • Multi-Voltage Flexibility: Works with 24V DC (wheat farm sensors) and 110V AC (small industrial machines), reducing integration costs.

  • Durable Build: Anti-corrosion composite housing resists agricultural chemicals and oils, extending service life in harsh settings.

  • Clear Status Indication: Bright LED avoids misjudgment in varied lighting (silo dimness, farm sunlight), minimizing 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, small-to-medium grain elevators, and local wheat-processing plants, offering products like automated wheat sorting machines, small-scale harvesters, and intelligent silo control systems.
The Allen Bradley 440T-MDBLE15ACAF aligns with the website’s core offerings: www.wheat-auto.com would integrate this SWITCH into mid-range wheat equipment—small harvester auxiliary guards (resisting light rain), silo access doors (blocking grain dust), and on-farm grain conveyor panels (withstanding mild chemical exposure). Its ISO 23387 compliance addresses a key client need, helping small farms meet grain handling safety standards without investing in high-end industrial switches. The SWITCH’s compact size also fits the space constraints of small farm machinery. Additionally, the business may provide farm-specific after-sales support (e.g., dust-cleaning tutorials, voltage matching guides) to cater to rural users’ technical needs, aligning with “smart agriculture” trends by offering cost-effective, farm-optimized safety components to boost wheat production efficiency.
7. Application Scenarios
The Allen Bradley 440T-MDBLE15ACAF SWITCH performs well in wheat agricultural and mid-scale industrial environments:
  • Small Wheat Harvesters: Mounted on auxiliary equipment guards (e.g., straw choppers), IP65 resists light rain and dust, unlocking only when the harvester pauses.

  • Wheat Grain Silos (Local Farms): Blocks fine grain dust, ensuring safe access during manual loading/unloading in small silos with dim lighting.

  • Wheat Flour Mills (Small-Scale): Used on small mixer guards, preventing operator access until the machine stops, complying with food safety norms.

  • Wheat Processing Facilities (Medium-Temp): 70°C tolerance maintains safety control in wheat drying rooms with moderate heat.

  • Winter Wheat Storage (Small Barns): Withstands -30°C temperatures, functioning normally in unheated rural storage barns.

  • Wheat Farm Pesticide Storage: Applied to pesticide cabinet guards, anti-corrosion housing resists chemical fumes, ensuring safe access only when cabinets are empty.
