1. Product Name
Allen Bradley 440T-ASCBE11EI Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-ASCBE11EI is a 24V DC-focused, IP65-rated safety interlock SWITCH with -30°C low-temperature resilience, engineered for medium-risk agricultural and industrial settings, ensuring reliable hazard control against dust, light moisture, and frigid conditions.
3. Product Description
The Allen Bradley 440T-ASCBE11EI is a specialized safety interlock SWITCH, part of Allen Bradley’s 440T series designed to address hazards in semi-harsh, low-temperature environments where 24V DC power systems are prevalent. This Allen Bradley SWITCH acts as a vital safety barrier, restricting access to high-risk zones—such as cold-region wheat silos or low-voltage industrial machines—until equipment is fully powered down and safety prerequisites are met.
Constructed with high-impact engineering plastic and reinforced zinc-alloy internal components, the Allen Bradley SWITCH achieves IP65 protection, effectively blocking dust ingress and light water splashes—ideal for covered cold agricultural facilities (e.g., winter wheat storage sheds) and indoor industrial areas with moderate debris. Its core interlock mechanism follows a fail-safe design: the SWITCH remains engaged (preventing unauthorized access) until connected systems (e.g., cold-region grain conveyors, small industrial robots) come to a complete stop, eliminating the risk of accidental contact with moving parts. Tailored for 24V DC power systems (a standard in agricultural automation and low-voltage industrial setups), the Allen Bradley SWITCH features compatible terminals that enable seamless integration with cold-farm control panels (e.g., silo frost monitors) and industrial safety PLCs, requiring no complex rewiring or voltage conversion.
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 ranging from -30°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 cold-region wheat cleaning machines or low-voltage conveyor systems. With a mechanical service life of 150,000 operations and compact dimensions (8.9×6.6×2.6cm), the Allen Bradley SWITCH balances durability, low-temperature resilience, and space efficiency for installations in tight spots, such as cold-storage wheat conveyor guard doors or industrial machine access panels.

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 cold-region grain storage, indoor processing, and semi-outdoor harvesting support. The business likely serves small to mid-sized wheat farms in temperate/cold zones, local grain elevators, and regional food processors, offering equipment such as cold-storage silos, temperature-controlled grain conveyors, and winter-resistant wheat cleaning machines.
Given the Allen Bradley 440T-ASCBE11EI’s -30°C resilience and IP65 protection, www.wheat-auto.com would integrate this SWITCH into cold-adapted wheat equipment: winter grain silo access doors (withstanding frost), covered cold-region conveyor guards (blocking snow-melt moisture), and cold-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 winter farm operations—critical for preventing accidents during frozen grain unloading or cold-equipment maintenance. Additionally, the business probably offers customized 24V DC-focused, cold-adapted automation packages (pairing this SWITCH with frost-resistant sensors and controls) to cater to farms in low-temperature zones, aligning with “smart agriculture” trends that prioritize climate-matched, reliable safety components for seamless, cost-effective cold-region farm operations.
7. Application Scenarios
The Allen Bradley 440T-ASCBE11EI SWITCH excels in 24V DC-powered, low-temperature, medium-risk environments across agriculture and industry:

  • Cold-Region Wheat Silos: Installed on silo access panels, -30°C resilience handles winter frost, while IP65 blocks snow-melt moisture—safe for frozen grain maintenance.

  • Covered Winter Grain Conveyors: Mounted on conveyor guard doors, 24V compatibility matches cold-farm power grids, and dust resistance protects against dry winter grain debris.

  • 24V DC Industrial Robot Cells (Cold Workshops): Used on small robot guard doors in low-temperature factories, compact design fits tight spaces, and IP65 blocks assembly dust.

  • Cold-Storage Wheat Cleaning Equipment: Integrated into cleaner access doors, -30°C performance adapts to refrigerated storage, and 24V DC powers the SWITCH seamlessly.

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

  • 24V DC Food Processing (Cold Dry Goods): Used on frozen flour packaging machine guards, IP65 blocks flour dust, and low-temperature resilience suits refrigerated processing areas.
