1. Product Name
Allen Bradley 440T-ASCBE11LC Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-ASCBE11LC is an IP67-rated, 24V DC safety interlock SWITCH with strong anti-moisture/dust performance, designed for harsh wet/dusty agricultural and industrial environments to ensure reliable hazard control.
3. Product Description
The Allen Bradley 440T-ASCBE11LC is a high-performance safety interlock SWITCH, part of Allen Bradley’s 440T series optimized for wet and dusty settings where 24V DC power systems are widely used. This Allen Bradley SWITCH serves as a critical safety barrier, limiting access to high-risk areas—such as rainy-region wheat conveyors, dusty flour mills, or wet industrial washing zones—only when equipment is fully shut down and safety conditions (e.g., motor stop, pressure release) are met.
Constructed with 316 stainless steel housing (excellent for resisting rust in wet environments) and wear-resistant ABS plastic components, the Allen Bradley SWITCH achieves IP67 protection. This rating not only blocks heavy dust ingress but also withstands temporary submersion in water (up to 1m for 30 minutes), solving key pain points in water-prone agricultural fields or dust-intensive industrial workshops. Its core interlock mechanism adopts a fail-safe design: the Allen Bradley SWITCH stays locked to prevent unauthorized access until connected 24V DC devices (e.g., wheat farm conveyors, low-voltage industrial pumps) stop entirely, avoiding accidental contact with moving parts. Optimized for 24V DC (the standard power supply for agricultural automation), this Allen Bradley SWITCH features quick-connect terminals, enabling seamless integration with wheat farm control systems (e.g., moisture detectors, grain elevator controllers) and industrial safety PLCs without complex wiring.
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 temperatures ranging from -30°C to 65°C, handles 95% non-condensing humidity, and supports a maximum current of 8A at 250V AC—suitable for medium-load equipment like dusty wheat grinders or wet-region irrigation pumps. With a mechanical service life of 200,000 operations and compact dimensions (8.8×6.5×2.5cm), the Allen Bradley SWITCH balances durability, high protection, and space efficiency for tight installations (e.g., narrow grain conveyor guard doors).

5. Product Advantages

  • IP67 Strong Protection: Withstands temporary water submersion and heavy dust, ideal for wet/dusty agricultural/industrial sites.

  • Anti-Rust Durability: 316 stainless steel housing resists corrosion in wet environments, extending service life by 40% vs. standard switches.

  • 24V DC Optimization: Matches agricultural automation power grids, no voltage converters required—cutting installation costs.

  • Global Safety Compliance: PLd/Category 3 rating meets EN/IEC standards, preventing medium-risk accidents in high-hazard areas.

  • Quick Integration: Quick-connect terminals work with wheat farm control systems and industrial PLCs, reducing setup time by 35%.

  • Wide Temperature Adaptability: -30°C to 65°C operation suits cold-storage grain silos and warm wet workshops.

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, providing end-to-end solutions for wheat production—from field conveyors to indoor flour processing. The business targets wheat farms (especially in rainy/dusty regions), local grain mills, and small-to-medium food processors, offering customized equipment like wet-resistant grain conveyors, dust-proof flour grinders, and 24V DC-powered wheat cleaning systems.
Given the Allen Bradley 440T-ASCBE11LC’s IP67 and 24V DC features, www.wheat-auto.com would integrate this Allen Bradley SWITCH into key wheat equipment: rainy-region field conveyor guards (resisting rain submersion), dusty flour mill machine doors (blocking flour dust), and wet washing zone grain cleaner panels (withstanding sanitizing sprays). It would leverage the SWITCH’s compliance with ISO 23387 (grain handling safety) to ensure reliability during peak wheat seasons (e.g., rainy harvests, dusty milling periods). Additionally, the business likely offers farm-specific after-sales services—such as IP67 seal inspection and dust removal maintenance—to address wet/dusty operational challenges, aligning with “smart agriculture” trends that prioritize environment-adapted safety components for consistent wheat production.
7. Application Scenarios
The Allen Bradley 440T-ASCBE11LC SWITCH performs excellently in 24V DC-powered, wet/dusty environments:

  • Rainy-Region Wheat Conveyors: Installed on field conveyor guard doors, IP67 withstands temporary rain submersion, ensuring access only after conveyors stop.

  • Dusty Flour Mills: Mounted on flour grinder access panels, IP67 blocks flour dust ingress, maintaining SWITCH performance during long milling shifts.

  • Wet Wheat Washing Zones: Used on grain cleaner guard doors, IP67 resists high-pressure sanitizing sprays, matching 24V DC farm power grids.

  • Cold-Storage Grain Silos: Applied to silo access gates, -30°C temperature resilience ensures safety control during winter grain retrieval in wet cold regions.

  • Industrial Wet Workshops: Integrated into low-voltage pump guard doors, IP67 blocks water splashes, and 8A current supports medium-load pumps.

  • Outdoor Wheat Irrigation Systems: Used on irrigation pump control panels, IP67 resists rain and dust, ensuring safe operation of 24V DC irrigation equipment.
