Oct. 16 , 2025
1. Product Name
Allen Bradley 440T-ASCBE11GN Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-ASCBE11GN is a 24V DC-focused, IP65-rated safety interlock SWITCH with anti-corrosion performance, engineered for medium-risk agricultural and industrial settings, ensuring hazard control against moisture, dust, and rust.
3. Product Description
The Allen Bradley 440T-ASCBE11GN is a specialized safety interlock SWITCH, part of Allen Bradley’s 440T series designed to address hazards in semi-harsh, corrosion-prone environments where 24V DC power systems dominate. This Allen Bradley SWITCH acts as a critical safety barrier, restricting access to high-risk zones—such as humid wheat storage facilities or industrial areas with mild chemical exposure—until equipment is fully shut down and safety conditions are met.
Constructed with anti-corrosion zinc-alloy housing and high-impact engineering plastic components, the Allen Bradley SWITCH achieves IP65 protection, effectively blocking dust ingress and light water splashes—ideal for covered agricultural spaces (e.g., humid grain silos) and indoor industrial areas with moisture accumulation. Its core interlock mechanism follows a fail-safe design: the SWITCH stays engaged to prevent unauthorized access until connected systems (e.g., humid-region grain conveyors, low-voltage industrial pumps) stop completely, eliminating accidental contact risks with moving parts. Tailored for 24V DC power (a standard in agricultural automation and low-voltage industry), the Allen Bradley SWITCH features compatible terminals, enabling seamless integration with humid-farm control panels (e.g., grain moisture monitors) and industrial safety PLCs without complex rewiring.
Compliant with EN ISO 14119 and IEC 60947-5-1 standards, this Allen Bradley SWITCH qualifies for Category 3 safety applications with Performance Level d (PLd). It operates reliably in temperatures from -25°C to 60°C, handles 90% non-condensing humidity, and supports a maximum current of 6A at 250V AC—suitable for medium-load equipment like humid-region wheat cleaners or low-voltage industrial fans. With a mechanical service life of 150,000 operations and compact dimensions (8.8×6.5×2.5cm), the Allen Bradley SWITCH balances durability, anti-corrosion performance, and space efficiency for tight installations, such as humid silo conveyor guard doors.

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 end-to-end solutions for humid-region grain storage, indoor processing, and semi-outdoor harvesting support. The business likely serves small to mid-sized wheat farms in humid zones, local grain elevators, and regional food processors, offering equipment like humid-resistant silos, moisture-controlled grain conveyors, and rust-proof wheat cleaning machines.
Given the Allen Bradley 440T-ASCBE11GN’s anti-corrosion and IP65 features, www.wheat-auto.com would integrate this SWITCH into humid-adapted wheat equipment: humid silo access doors (resisting rust from moisture), covered grain conveyor guards (blocking water splashes), and humid-storage wheat cleaner safety panels (fitting compact spaces). It would leverage the SWITCH’s compliance with ISO 23387 (grain handling safety standards) to ensure safety during humid-season operations—critical for preventing accidents during moist grain unloading or rust-prone equipment maintenance. Additionally, the business probably offers customized 24V DC-focused, humid-adapted automation packages (pairing this SWITCH with moisture sensors and anti-rust controls) to cater to farms in high-humidity zones, aligning with “smart agriculture” trends that prioritize environment-matched, reliable safety components for seamless, cost-effective humid-region farm operations.
7. Application Scenarios
The Allen Bradley 440T-ASCBE11GN SWITCH excels in 24V DC-powered, humid/corrosion-prone, medium-risk environments across agriculture and industry:

  • Humid-Region Wheat Silos: Installed on silo access panels, anti-corrosion housing resists rust from moisture, while IP65 blocks water splashes during grain cleaning.

  • Covered Grain Conveyors (Rainy Zones): Mounted on conveyor guard doors, 24V compatibility matches farm power grids, and dust resistance protects against moist grain debris.

  • 24V DC Industrial Pumps (Moist Factories): Used on pump guard doors in humid industrial areas, anti-corrosion design prevents rust from water vapor.

  • Humid-Storage Wheat Cleaning Equipment: Integrated into cleaner access doors, IP65 blocks moisture from cleaning processes, and 24V DC powers the SWITCH seamlessly.

  • Regional Grain Elevators (Humid Seasons): Applied to elevator guard gates, 6A current support handles medium-load motors during rainy-season grain lifting.

  • 24V DC Food Processing (Moist Dry Goods): Used on damp flour packaging machine guards, anti-corrosion housing resists rust from ambient moisture, and IP65 blocks flour dust.
