1. Product Name
Allen Bradley 440T-ASCBE11CA Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-ASCBE11CA is a 24V DC-focused, IP65-rated safety interlock SWITCH, engineered for medium-risk agricultural and industrial settings, ensuring reliable hazard control against dust and light moisture.
3. Product Description
The Allen Bradley 440T-ASCBE11CA is a specialized safety interlock SWITCH, part of Allen Bradley’s 440T series designed to address hazards in semi-harsh environments where 24V DC power systems are commonly used. This Allen Bradley SWITCH acts as a vital safety barrier, restricting access to high-risk zones—such as wheat farm silos or small-scale 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 agricultural facilities (e.g., 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., 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 wheat farm control panels (e.g., silo temperature 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 -20°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 wheat cleaning machines or small 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, voltage compatibility, and space efficiency for installations in tight spots, such as 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 covered grain storage, indoor processing, and semi-outdoor harvesting support. The business likely serves small to mid-sized wheat farms, local grain elevators, and regional food processors, offering equipment such as automated grain conveyors, silo monitoring systems, and wheat cleaning machines.
Given the Allen Bradley 440T-ASCBE11CA’s 24V DC specialization and IP65 protection, www.wheat-auto.com would integrate this SWITCH into 24V-powered wheat equipment: covered grain conveyor guards (resisting wheat dust), indoor silo access doors (withstanding mild moisture), and 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 daily farm operations—critical for preventing accidents during grain loading/unloading or equipment maintenance. Additionally, the business probably offers customized 24V DC-focused automation packages (pairing this SWITCH with compatible sensors and controls) to cater to small farms using low-voltage systems, aligning with “smart agriculture” trends that prioritize voltage-matched, reliable safety components for seamless, cost-effective farm operations.
7. Application Scenarios
The Allen Bradley 440T-ASCBE11CA SWITCH excels in 24V DC-powered, medium-risk environments across agriculture and industry:

  • Covered Wheat Conveyors (24V Grids): Installed on conveyor guard doors, 24V compatibility matches farm automation power, while IP65 blocks grain dust—safe for daily grain transport.

  • Indoor Wheat Silos: Mounted on silo access panels, mild moisture resistance suits damp storage conditions, and fail-safe interlock ensures safe maintenance checks.

  • 24V DC Industrial Robot Cells: Used on small robot guard doors, compact design fits tight machine spaces, and IP65 blocks assembly debris.

  • Wheat Cleaning Equipment: Integrated into cleaner access doors, 24V DC 适配 (compatibility) powers the SWITCH seamlessly, and dust resistance protects internal components.

  • Local Grain Elevators: Applied to elevator guard gates, 6A current support adapts to medium-load elevator motors, handling seasonal grain lifting demands.

  • 24V DC Food Processing (Dry Goods): Used on flour packaging machine guards, IP65 blocks flour dust, and safety interlock prevents access during high-speed packaging.
