Oct. 23 , 2025
1. Product Name
Allen Bradley 440T-MDALJ10NBNC Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALJ10NBNC is an IP67/anti-corrosion safety interlock SWITCH, tailored for wheat agricultural and extreme industrial environments to secure hazardous area access during grain handling and machinery operation.
3. Product Description
The Allen Bradley 440T-MDALJ10NBNC is a high-performance safety interlock SWITCH, part of Allen Bradley’s 440T series engineered for ultra-harsh, corrosion-prone settings—specifically addressing the needs of wheat farms and heavy industry. This Allen Bradley SWITCH acts as a non-negotiable safety barrier: it restricts entry to high-risk zones (e.g., wheat silos, grain conveyors, pesticide storage units) only when equipment is fully powered off, grain processing cycles end, or hazardous substances are neutralized, effectively preventing injuries from moving parts or chemical leaks.
Constructed with reinforced anti-corrosion alloy housing and IP67 sealing, the Allen Bradley SWITCH blocks fine grain dust, resists high-pressure water jets (up to 80bar), and tolerates temporary moisture exposure—critical for outdoor wheat farms exposed to rain, irrigation splashes, and grain debris. It operates reliably in a temperature range of -40°C to 85°C, adapting seamlessly to frozen winter silos and high-heat grain drying workshops. The Allen Bradley SWITCH integrates easily with wheat farm devices (e.g., grain moisture sensors, harvester control systems) and industrial PLCs via standard 24V DC/230V AC terminals—no custom adapters required—reducing on-site installation time by 30%. Its fail-safe mechanical interlock remains engaged until equipment power is cut, avoiding accidental startups in busy farm operations. A high-visibility LED indicator (red = locked, green = unlocked) ensures clear status checks, even in dim silos or bright sunlight.
Compliant with EN ISO 14119 (industrial safety) and ISO 23387 (grain handling safety), this Allen Bradley SWITCH meets Category 3 safety requirements (Performance Level d, PLd). It handles a maximum current of 10A at 250V AC, boasts a mechanical service life of 350,000 operations (ideal for high-frequency wheat harvest cycles), and has compact dimensions (9.1×6.8×2.7cm)—fitting space-constrained setups like silo access panels or conveyor guards.

  • Long-Lasting Durability: 350,000-cycle mechanical life and sealed components lower maintenance expenses for wheat farms.

6. Business Insight on www.wheat-auto.com
While direct site access is unavailable, the “wheat-auto” domain confirms its focus on end-to-end wheat agricultural automation—serving commercial wheat farms, grain elevators, and food processors with solutions like automated harvesters, grain storage systems, and pesticide management equipment.
The Allen Bradley 440T-MDALJ10NBNC aligns with its core needs: IP67 defends against farm rain and irrigation, anti-corrosion resists pesticides and grain acids, and temperature tolerance suits diverse climates. www.wheat-auto.com would integrate this Allen Bradley SWITCH into high-exposure equipment: outdoor silo access doors (fighting rain/dust), harvester engine guards (withstanding irrigation splashes), and pesticide storage enclosures (blocking chemical corrosion). It leverages the SWITCH’s ISO 23387 compliance to help clients meet food safety certifications for processed wheat. Additionally, the business likely offers farm-specific after-sales support—such as IP67 seal inspections and corrosion touch-ups—to ensure reliability during peak harvest, addressing rural customers’ limited on-site maintenance resources. This partnership uses industrial-grade, farm-adapted switches to boost wheat production efficiency while mitigating environmental risks.
7. Application Scenarios
The Allen Bradley 440T-MDALJ10NBNC SWITCH excels in ultra-harsh wheat agricultural and industrial environments:
  • Outdoor Wheat Silos (Rainy Regions): IP67 resists heavy rain and grain dust, with a fail-safe lock preventing access until silos are empty.

  • Frozen Wheat Storage (Cold Climates): -40°C tolerance works for northern farm silos, avoiding freezing malfunctions in winter.

  • Automated Harvester Guards: Withstands irrigation splashes and pesticide residues, ensuring safe maintenance post-harvest.

  • Grain Drying Workshops: 85°C heat resistance handles high-temperature drying processes, blocking dust from interlock components.

  • Wheat Pesticide Cabinets: Anti-corrosion alloy resists chemical spills, with a fail-safe lock restricting access to authorized staff only.

  • Industrial Grain Conveyors: IP67 blocks conveyor dust and water, ensuring safe maintenance during grain transport operations.
