1. Product Name
Allen Bradley 440T-ASCBE14VD Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-ASCBE14VD is an IP66-rated safety interlock SWITCH with 316 stainless steel and wide voltage compatibility, designed for agri-industrial environments with chemical exposure and varied power supplies.
3. Product Description
The Allen Bradley 440T-ASCBE14VD is a high-performance safety interlock SWITCH, part of Allen Bradley’s 440T series tailored for agri-industrial settings—such as wheat farms (pesticide sprayers, fertilizer mixers) and grain processing plants—where both chemical resistance and flexible voltage adaptation are critical. This Allen Bradley SWITCH acts as a vital safety barrier, allowing access to hazardous zones only when machinery is fully shut down, chemical residues are cleared, or pressure systems are stabilized.
Constructed with 316 stainless steel housing (resistant to wheat pesticides, fertilizers, and industrial cleaners) and chemical-resistant internal components, the Allen Bradley SWITCH achieves IP66 protection. This rating ensures complete dust tightness and resistance to high-pressure water jets (up to 100bar), making it suitable for post-chemical washdowns or outdoor rain exposure. Its key advantage lies in wide voltage compatibility: it operates seamlessly across 12V DC to 240V AC, adapting to diverse power sources in rural farms (solar-powered equipment) and industrial facilities (standard grid power)—a critical feature for wheat farms with mixed machinery types. The Allen Bradley SWITCH integrates easily with agricultural controls (e.g., wheat harvester safety circuits) and industrial PLCs via flame-retardant terminals, reducing fire risks from chemical fumes.
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 functions reliably in temperatures from -40°C to 70°C, handles 95% non-condensing humidity (even with chemical vapors), and supports 10A current at 250V AC—ideal for high-load equipment like chemically treated grain conveyors. With a 250,000-operation mechanical life and compact dimensions (8.5×6.2×2.4cm), the Allen Bradley SWITCH balances durability, voltage flexibility, and space efficiency for tight installations (e.g., pesticide sprayer guards).

5. Product Advantages

  • Wide Voltage Compatibility: 12V DC to 240V AC operation adapts to solar-powered farm gear and industrial grid systems, reducing power mismatch issues.

  • Strong Chemical Resistance: 316 stainless steel withstands wheat pesticides/fertilizers, avoiding corrosion in agri-chemical zones.

  • IP66 Heavy-Duty Protection: Blocks dust and 100bar water jets, reliable for washdowns and outdoor rain exposure.

  • Broad Temperature Range: -40°C to 70°C suits cold wheat farms (winter storage) and heated chemical processing areas.

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

  • Long Durability: 250,000-cycle life cuts replacement costs in high-use agri-industrial 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 farms and grain processors with mixed power setups (solar, grid) and chemical exposure. It targets commercial wheat farms, offering systems like solar-powered pesticide sprayers, multi-voltage grain conveyors, and outdoor fertilizer mixing units.
The Allen Bradley 440T-ASCBE14VD’s wide voltage compatibility and IP66/chemical resistance make it a core component here: integrated into solar-powered pesticide sprayer guards (adapting to 12V DC solar systems) and multi-voltage grain conveyor gates (matching 240V AC grid power). The site likely leverages the SWITCH’s compliance with ISO 23387 (grain handling safety) to ensure reliability in rural setups. It may also provide farm-specific support—like voltage configuration guidance and corrosion inspections—to address challenges of mixed power sources in wheat operations. This aligns with “smart agriculture” trends, using the Allen Bradley SWITCH to unify safety across diverse equipment.
7. Application Scenarios
The Allen Bradley 440T-ASCBE14VD SWITCH excels in agri-industrial settings with varied power and chemical exposure:

  • Solar-Powered Wheat Pesticide Sprayers: Installed on sprayer guards, 12V DC compatibility matches solar systems—unlocks only when sprayers stop.

  • Multi-Voltage Grain Conveyors: Mounted on conveyor guards, adapts to 110V AC (farm sheds) and 240V AC (processing plants) while resisting grain dust.

  • Outdoor Fertilizer Mixers: Used on mixer access doors, IP66 resists rain and 316 steel withstands alkaline fertilizer residues.

  • Chemical-Treated Wheat Silos: Integrated into silo doors, handles post-sanitization washdowns and adapts to silo’s 24V DC control systems.

  • Industrial Chemical Tanks: Applied to tank guards, wide voltage works with factory 240V AC and resists chemical fumes.

  • Cold-Region Wheat Farms: Used on pesticide shed doors, -40°C resilience ensures safety in winter, with voltage adapting to backup generators.
