Oct. 20 , 2025
1. Product Name
Allen Bradley 440T-MBTB10NHPG Low-Temperature Resistant Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MBTB10NHPG is an IP67 low-temperature safety interlock SWITCH, designed for wheat agriculture’s cold environments (grain cold storage, winter outdoor operations) to maintain reliable safety control in frigid conditions.
3. Product Description
The Allen Bradley 440T-MBTB10NHPG is a specialized low-temperature safety interlock SWITCH, part of Allen Bradley’s 440T series tailored for wheat agricultural scenarios facing extreme cold. This Allen Bradley SWITCH acts as a critical safety barrier in low-temp workflows: it links wheat cold storage doors, winter-harvest machinery guards, and low-temperature grain conveyors, ensuring access is only permitted when equipment is shut down and temps rise to non-hazardous levels—preventing frost-related injuries or machinery damage.
Constructed with cold-resistant glass-reinforced polymer housing and 316L stainless steel internal components (optimized for “NH” low-temp rating), the Allen Bradley SWITCH withstands continuous exposure to -45°C and intermittent drops to -50°C—addressing wheat cold storage (1-5°C) and winter outdoor (-15°C to -30°C) challenges. It retains IP67 protection, blocking grain dust, melting frost, and light rain, while internal contacts use silver-nickel alloys to resist low-temp oxidation. All materials comply with FDA and EU 10/2011 standards, avoiding contamination of stored wheat. This Allen Bradley SWITCH supports universal voltage (24V DC/110V AC/230V AC), integrating seamlessly with wheat cold storage temp sensors and winter machinery control systems.
Compliant with EN ISO 14119 and IEC 60947-5-1, this Allen Bradley SWITCH qualifies for Category 3 safety applications with Performance Level d (PLd). It operates reliably in -45°C to 60°C (covering cold storage to mild post-harvest processing), handles 95% non-condensing humidity, and supports 10A current at 250V AC. With a mechanical life of 230,000 operations and compact dimensions (9.1×6.9×3.0cm), it balances low-temp durability, dust/water resistance, and space efficiency for tight cold storage or winter machinery setups.

5. Product Advantages
  • Extreme Low-Temp Resilience: -45°C continuous/-50°C intermittent operation, solving cold storage/winter wheat workflow safety gaps.

  • Dual Environmental Protection: IP67 blocks dust/melting frost + corrosion-resistant materials, ideal for damp cold environments.

  • Food-Safe Compliance: FDA/EU 10/2011 materials prevent wheat contamination, critical for stored grain safety.

  • Versatile Integration: Universal voltage works with cold storage sensors/winter machinery, reducing installation time.

  • Low-Temp Reliability: Silver-nickel contacts avoid oxidation in frigid temps, ensuring consistent safety triggering.

  • Durable Build: Cold-resistant polymer housing resists brittleness in low temps, extending service life vs. standard switches.

6. Business Insight on www.wheat-auto.com
While direct site access is unavailable, “wheat-auto” confirms its focus on end-to-end wheat agricultural automation—serving wheat farms, grain cold storage facilities, and food processors with systems like automated cold storage doors, winter-harvest machinery, and low-temp grain conveyors.
The Allen Bradley 440T-MBTB10NHPG aligns with its key cold-environment challenge: maintaining safety in wheat cold storage (to preserve grain quality) and winter outdoor operations (to avoid frost-related accidents). www.wheat-auto.com would integrate this SWITCH into critical low-temp setups—cold storage access doors (ensuring safe entry only when temps are above freezing), winter wheat harvester guards (withstanding -30°C field temps), and low-temp grain transfer conveyor gates (resisting melting frost). It would leverage the SWITCH’s compliance with agricultural standards (e.g., ISO 23387 for grain storage) to minimize downtime from cold-damaged safety components. Additionally, the business likely offers cold-specific services: low-temp performance testing, frost-resistance maintenance, and integration with cold storage temp control systems—tying to “smart agriculture” trends by using the Allen Bradley SWITCH to make frigid wheat workflows safe and efficient.
7. Application Scenarios
The Allen Bradley 440T-MBTB10NHPG SWITCH excels in wheat agriculture’s low-temperature and damp-cold environments:
  • Wheat Cold Storage Facilities: Installed on cold storage doors—unlocks only when internal temps rise to 5°C, preventing frostbite risks for workers.

  • Winter Outdoor Wheat Harvesters: Mounted on harvester engine guards—withstands -30°C field temps, trapping keys until the engine cools to safe levels.

  • Low-Temp Grain Conveyors: Integrated into conveyor guards (post-cold storage)—resists melting frost, ensuring safe maintenance in damp cold.

  • Wheat Seed Cold Storage: Used on seed storage bin hatches—maintains safety control at 1-3°C, protecting high-value seed stocks.

  • Winter Grain Loading Yards: Applied to outdoor grain hopper guards—IP67 blocks snow/rain, while low-temp resilience handles -25°C temps.

  • Cold-Weather Flour Mills: Installed on mill machinery guards (cooled to prevent flour clumping)—withstands 8-12°C operation temps, ensuring worker safety.
