1. Product Name
Allen Bradley 440T-ASCBE11UZ Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-ASCBE11UZ is an IP68-rated safety interlock SWITCH with 316 stainless steel housing, built for ultra-harsh environments (prolonged submersion, salt spray) in agriculture and industry to ensure fail-safe hazard control.
3. Product Description
The Allen Bradley 440T-ASCBE11UZ is a heavy-duty safety interlock SWITCH, part of Allen Bradley’s 440T series engineered for extreme operational conditions where standard safety components falter. This Allen Bradley SWITCH acts as a non-negotiable safety barrier, restricting access to high-risk zones—such as tidal zone wheat farms, flood-prone grain silos, or industrial deep-tank facilities—only when equipment is fully shut down and safety prerequisites (e.g., pressure release, motor stop) are met.
Constructed with marine-grade 316 stainless steel (superior to 304 in corrosion resistance) and impact-resistant glass-reinforced polymer, the Allen Bradley SWITCH achieves IP68 protection. This rating enables it to withstand prolonged submersion (1.5m depth for 24 hours), block heavy dust ingress, and resist high-pressure water jets (up to 100bar)—critical for tidal wheat farms (saltwater submersion) or industrial sites with frequent floods. Its core interlock mechanism follows a fail-safe design: the Allen Bradley SWITCH remains locked to prevent unauthorized entry until connected equipment (compatible with 24V DC/110V AC/230V AC power grids) ceases operation entirely, eliminating accident risks from moving parts. Equipped with universal terminal blocks, this Allen Bradley SWITCH integrates seamlessly with wheat farm systems (e.g., tidal-resistant moisture sensors, flood-adapted elevator controllers) and industrial safety PLCs without extra voltage converters.
Compliant with EN ISO 14119 and IEC 60947-5-1 standards, the Allen Bradley SWITCH qualifies for Category 3 safety applications with Performance Level d (PLd). It operates stably in a temperature range of -35°C to 75°C, handles 95% non-condensing humidity, and supports a maximum current of 10A at 250V AC—suitable for heavy-load equipment like tidal zone wheat harvesters or industrial deep tanks. With a mechanical service life of 220,000 operations and compact dimensions (8.9×6.7×2.7cm), the Allen Bradley SWITCH balances ultra-durability and space efficiency, fitting into narrow spots like tight conveyor guards or small machinery panels.

5. Product Advantages

  • IP68 Ultra-Protection: Withstands 1.5m submersion for 24h, high-pressure water, and dust—ideal for tidal/flood-prone sites.

  • 316 Stainless Steel Housing: Marine-grade corrosion resistance resists saltwater (tidal wheat farms) and chemical spills (industrial tanks).

  • Wide Voltage Compatibility: 24V DC/110V AC/230V AC support matches mixed agri/industrial grids, no extra converters needed.

  • Global Safety Compliance: PLd/Category 3 rating meets EN/IEC standards, preventing medium-risk accidents in ultra-harsh environments.

  • Broad Temperature Adaptability: -35°C to 75°C operation suits frigid grain silos and hot industrial workshops.

  • Easy Integration: Universal terminals cut installation time by 30% when pairing with farm/industrial control systems.

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, offering end-to-end solutions: tidal zone harvest machinery, flood-adapted grain silos, dust-resistant processing lines, and coastal storage systems. It targets tidal wheat farms, flood-prone rural grain mills, and coastal grain elevators, providing customized equipment like saltwater-resistant harvesters and submersion-ready silo doors.
The Allen Bradley 440T-ASCBE11UZ’s IP68 protection and 316 stainless steel make it a core component of www.wheat-auto.com’s offerings: integrated into tidal zone wheat harvester engine guards (resisting saltwater submersion), flood-prone silo access doors (withstanding 24h immersion), and coastal elevator controls (blocking salt spray). The business leverages the SWITCH’s compliance with ISO 23387 (grain handling safety standards) to ensure reliability during tidal harvests or floods. Additionally, it likely offers farm-specific after-sales services—316 stainless steel corrosion testing, IP68 seal maintenance—to address rural tidal challenges, aligning with “smart agriculture” trends that demand environment-adapted safety components for consistent wheat production.
7. Application Scenarios
The Allen Bradley 440T-ASCBE11UZ SWITCH excels in ultra-harsh environments across agriculture and industry:

  • Tidal Zone Wheat Harvesters: Installed on engine guards, 316 steel resists saltwater, while IP68 handles 24h tidal submersion during harvest.

  • Flood-Prone Grain Silos: Mounted on access doors, prolonged submersion protection prevents accidents during seasonal floods.

  • Industrial Deep Chemical Tanks: Used on tank guards, 316 steel resists chemical spills, and IP68 blocks water from cleaning processes.

  • Deep-Sea Mining Conveyors: Integrated into guard doors, IP68 resists seawater submersion, and 316 steel prevents rust in marine conditions.

  • Rainy-Tidal Region Wheat Elevators: Applied to elevator access panels, IP68 handles heavy rain/tidal spray, and multi-voltage compatibility matches 230V AC motors.

  • Coastal Small Flour Mills: Used on grinder guards, compact dimensions fit narrow spaces, and 316 steel resists salt-laden air that degrades standard parts.
