Oct. 17 , 2025
1. Product Name
Allen Bradley 440T-ASCBE14XH Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-ASCBE14XH is an IP67-rated safety interlock SWITCH with 316 stainless steel, built for harsh outdoor/agri-industrial environments with extreme weather (heavy rain, temporary submersion).
3. Product Description
The Allen Bradley 440T-ASCBE14XH is a rugged safety interlock SWITCH, part of Allen Bradley’s 440T series engineered for high-risk agri-industrial scenarios—such as flood-prone wheat farms, coastal grain silos, and outdoor chemical mixing zones—where enhanced water resistance and corrosion protection are non-negotiable. This Allen Bradley SWITCH acts as a critical safety barrier, permitting access to hazardous zones only when machinery is fully de-energized, chemical spills are contained, or water exposure risks are eliminated.
Constructed with thick-gauge 316 stainless steel housing (resistant to salt spray, wheat pesticides, and industrial solvents) and sealed internal components, the Allen Bradley SWITCH achieves IP67 protection—surpassing standard IP66 by withstanding temporary submersion (up to 1m for 30 minutes), making it ideal for flood-prone farm fields or washdown zones with accidental water pooling. Its core advantage lies in wide voltage adaptability (12V DC to 240V AC), seamlessly matching solar-powered wheat harvesters (rural farms) and grid-powered grain processors (industrial sites)—a key solution for mixed-equipment operations. The Allen Bradley SWITCH integrates with agricultural control systems (e.g., wheat irrigation safety circuits) and industrial PLCs via flame-retardant terminals, reducing fire risks from chemical vapors common in fertilizer storage.
Compliant with EN ISO 14119 and IEC 60947-5-1 standards, the Allen Bradley SWITCH meets Category 3 safety requirements with Performance Level d (PLd). It operates reliably in temperatures from -40°C to 75°C (wider than standard models, suiting polar wheat storage and desert farms), handles 95% non-condensing humidity (even with chemical vapors), and supports 10A current at 250V AC for high-load equipment like water-subjected grain conveyors. With a 300,000-operation mechanical life (longer than series averages) and compact dimensions (8.6×6.3×2.5cm), the Allen Bradley SWITCH balances durability, extreme weather resilience, and space efficiency for tight installations (e.g., outdoor irrigation pump guards).

5. Product Advantages

  • IP67 Enhanced Protection: Withstands 1m submersion for 30 minutes, ideal for flood-prone farms and water-pooling washdowns.

  • Superior Corrosion Resistance: Thick 316 stainless steel resists coastal salt spray and wheat pesticide/fertilizer damage.

  • Wide Voltage Compatibility: 12V DC-240V AC adapts to solar farms and industrial grids, eliminating power mismatch issues.

  • Extreme Temperature Range: -40°C to 75°C suits cold wheat storage (winter) and desert farm (summer) operations.

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

  • Longer Service Life: 300,000 mechanical cycles reduce replacement costs in high-use outdoor environments.

6. Business Insight on www.wheat-auto.com
While direct site access is unavailable, the domain “wheat-auto” confirms a focus on wheat-centric agricultural automation, specializing in solutions for extreme-environment operations (flood-prone fields, coastal farms, desert wheat plantations). It targets commercial wheat farms and grain processors, offering systems like flood-resistant grain conveyors, solar-powered irrigation pumps, and coastal silo safety networks.
The Allen Bradley 440T-ASCBE14XH’s IP67 submersion resistance and 316 steel corrosion protection make it a core component here: integrated into flood-prone wheat harvester guards (withstanding temporary water coverage) and coastal silo access doors (resisting salt spray). The site likely leverages the SWITCH’s compliance with ISO 23387 (grain handling safety) and wide voltage support to unify safety across mixed-power setups (solar irrigation + grid silos). It may also provide farm-specific services—like flood-resistance testing and salt-corrosion maintenance—to address rural environmental challenges. This aligns with “smart agriculture” trends, using the Allen Bradley SWITCH to ensure safety in conditions where standard interlocks fail.
7. Application Scenarios
The Allen Bradley 440T-ASCBE14XH SWITCH excels in extreme weather/chemical agri-industrial settings:

  • Flood-Prone Wheat Harvesters: Installed on harvester engine guards, IP67 withstands temporary submersion—unlocks only when engines stop.

  • Coastal Grain Silos: Mounted on silo doors, 316 steel resists salt spray and IP67 blocks rain, ensuring safe grain unloading.

  • Solar-Powered Irrigation Pumps: Used on pump guards, 12V DC compatibility matches solar systems, withstanding rainwater pooling.

  • Desert Wheat Farms: Integrated into fertilizer mixer doors, 75°C heat resistance and IP67 dust/water protection ensure reliability.

  • Outdoor Chemical Storage (Wheat Pesticides): Applied to tank guards, IP67 prevents water damage and 316 steel resists chemical 腐蚀.

  • Cold-Region Silage Yards: Used on silage pit doors, -40°C resilience works with backup generators (240V AC) for winter safety.
