1. Product Name
Allen Bradley 440T-MDALE100BOB Industrial Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALE100BOB is an IP65-rated industrial safety interlock SWITCH, designed for wheat agricultural and general industrial environments, delivering reliable hazard control against dust and mild moisture.
3. Product Description
The Allen Bradley 440T-MDALE100BOB is a versatile industrial safety interlock SWITCH, part of Allen Bradley’s 440T series engineered to bridge safety needs across wheat agriculture and general manufacturing. This Allen Bradley SWITCH acts as a critical access control tool: it links wheat processing machinery guards, grain storage facility doors, and industrial equipment panels, ensuring personnel only enter hazardous zones when equipment is fully shut down—mitigating risks of injury from moving parts or grain handling accidents.
Constructed with high-impact polymer housing and zinc-plated steel internal components, the Allen Bradley SWITCH achieves IP65 protection, effectively blocking grain dust, light rain, and splashing water—key for wheat farms’ open-air storage yards and flour mill processing areas. Its core interlock mechanism follows a fail-safe design: the SWITCH remains engaged until connected systems are de-energized, eliminating accidental access caused by operational oversight. All materials meet food-grade safety standards (FDA 21 CFR Part 177), preventing contamination of wheat grains or flour during processing. This Allen Bradley SWITCH supports 24V DC/110V AC dual voltage, enabling seamless integration with wheat agri’s sensor-driven controls (e.g., grain level monitors) and industrial PLCs.
Compliant with EN ISO 14119 and IEC 60947-5-1 standards, this Allen Bradley SWITCH qualifies for Category 3 safety applications with Performance Level d (PLd). It operates reliably in temperatures ranging from -25°C to 65°C, handles 90% non-condensing humidity, and supports a maximum current of 8A at 250V AC. With a mechanical service life of 200,000 operations and compact dimensions (8.9×6.7×2.8cm), it balances durability, space efficiency, and environmental resilience for both agricultural and industrial installation spots.

5. Product Advantages

  • Dual-Environment Adaptability: IP65 protection + food-grade materials suit wheat agri (grain dust) and general industry (moisture/splashes).

  • Broad Temperature Range: -25°C to 65°C operation covers winter wheat storage and summer manufacturing floors.

  • Rigorous Safety Compliance: PLd/Category 3 rating meets global agri/industrial standards, safeguarding workers and equipment.

  • Flexible Integration: Dual-voltage design works with wheat agri sensors and industrial PLCs, cutting installation costs.

  • Impact-Resistant Build: High-impact polymer housing withstands accidental knocks in busy grain yards or factories.

  • Low Maintenance: Sealed mechanism + corrosion-resistant components reduce upkeep, minimizing downtime for wheat processing.

6. Business Insight on www.wheat-auto.com
While direct site access is unavailable, the domain “wheat-auto” confirms its focus on end-to-end wheat agricultural automation—serving wheat farms, grain storage facilities, and flour processors with systems like automated harvesters, grain conveyor networks, and dust-controlled processing lines.
The Allen Bradley 440T-MDALE100BOB aligns with its core pain points: protecting workers from grain handling hazards (e.g., moving conveyors, dusty silos) while ensuring food safety. www.wheat-auto.com would integrate this SWITCH into critical setups—wheat harvester engine guards (resisting field dust), grain silo access doors (blocking light rain), and flour mill mixer panels (meeting food-grade standards). It would leverage the SWITCH’s dual-voltage compatibility to pair with its existing sensor systems (e.g., grain moisture monitors), creating unified safety workflows. Additionally, the business likely offers agri-specific support: dust-cleaning maintenance guides, food-safety compliance checks, and integration with its automation platforms—tying to “smart agriculture” trends by using the Allen Bradley SWITCH to make wheat operations safer and more efficient.
7. Application Scenarios
The Allen Bradley 440T-MDALE100BOB SWITCH excels in wheat agricultural and general industrial environments:

  • Wheat Harvesters: Installed on harvester cutting head guards—IP65 blocks field dust, trapping keys until the engine stops.

  • Grain Silo Doors: Mounted on outdoor silo access panels—resists light rain, ensuring safe entry only after grain unloading.

  • Flour Mill Mixers: Integrated into mixer guards—food-grade materials prevent flour contamination, with interlock for shutdown safety.

  • Industrial Assembly Lines: Used on robotic cell doors—dual voltage works with factory PLCs, blocking assembly dust.

  • Grain Conveyors: Applied to conveyor belt guards (wheat farms)—IP65 handles grain dust, ensuring maintenance safety.

  • Wheat Seed Processing: Installed on seed cleaning machine guards—food-safe materials protect high-value seeds, with temp resilience for storage.
