1. Product Name
Allen Bradley 440T-ASCBE11SR Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-ASCBE11SR is an IP67-rated safety interlock SWITCH with 316 stainless steel housing, engineered for extreme harsh environments (salt spray, moisture, dust) in agriculture and industry to ensure reliable hazard control.
3. Product Description
The Allen Bradley 440T-ASCBE11SR is a rugged safety interlock SWITCH, part of Allen Bradley’s 440T series designed for high-stress operational scenarios where standard safety components fail. This Allen Bradley SWITCH acts as a critical safety barrier, restricting access to high-risk zones—such as coastal wheat farm machinery, industrial chemical tanks, or flood-prone grain elevators—only when equipment is fully shut down and safety prerequisites (e.g., pressure release, motor stop) are satisfied.
Constructed with marine-grade 316 stainless steel (offering superior corrosion resistance vs. 304 stainless steel) and impact-resistant glass-reinforced polymer, the Allen Bradley SWITCH achieves IP67 protection. This rating enables it to block heavy dust ingress, withstand high-pressure water jets (up to 100bar), and endure short-term submersion (1m depth for 30 minutes)—essential for coastal agricultural sites (salt spray exposure) or industrial areas prone to spills. 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., salt-resistant moisture sensors, coastal elevator controllers) and industrial safety PLCs without requiring additional 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 -30°C to 70°C, handles 95% non-condensing humidity, and supports a maximum current of 10A at 250V AC—suitable for heavy-load equipment like coastal wheat harvesters or industrial mixers. With a mechanical service life of 200,000 operations and compact dimensions (8.8×6.6×2.6cm), the Allen Bradley SWITCH balances extreme durability and space efficiency, fitting into narrow installation spots such as tight conveyor guards or small machinery panels.

5. Product Advantages

  • IP67 Extreme Protection: Resists dust, high-pressure water, and short submersion—ideal for flood-prone/coastal agri/industrial sites.

  • 316 Stainless Steel Housing: Marine-grade corrosion resistance withstands salt spray (coastal wheat farms) and chemical exposure (industrial tanks).

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

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

  • Broad Temperature Adaptability: -30°C to 70°C operation suits frigid grain silos and hot industrial workshops.

  • Easy Integration: Universal terminals reduce 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: outdoor harvest machinery, coastal grain storage systems, dust-resistant processing lines, and flood-adapted silo setups. It targets coastal wheat farms, regional grain mills, and flood-prone rural operations, providing customized equipment like salt-resistant conveyors and submersion-ready silo doors.
The Allen Bradley 440T-ASCBE11SR’s IP67 protection and 316 stainless steel make it a core component of www.wheat-auto.com’s offerings: integrated into coastal wheat harvester engine guards (resisting salt spray), flood-prone silo access doors (withstanding short submersion), and outdoor elevator controls (blocking heavy rain). The business leverages the SWITCH’s compliance with ISO 23387 (grain handling safety standards) to ensure reliability during coastal harvests or rainy seasons. Additionally, it likely offers farm-specific after-sales services—316 stainless steel corrosion inspections, IP67 seal maintenance—to address rural coastal challenges, aligning with “smart agriculture” trends that demand environment-adapted safety components for consistent wheat production.
7. Application Scenarios
The Allen Bradley 440T-ASCBE11SR SWITCH excels in extreme harsh environments across agriculture and industry:

  • Coastal Wheat Harvesters: Installed on engine guards, 316 steel resists salt spray, while IP67 handles ocean mist and heavy rain during harvest.

  • Flood-Prone Grain Silos: Mounted on access doors, short submersion protection safeguards against seasonal floods that risk silo access accidents.

  • Industrial Chemical Tanks: Used on tank guards, 316 steel resists chemical spills, and IP67 blocks water from cleaning processes.

  • Wet Mining Conveyors: Integrated into guard doors, IP67 resists underground moisture, and 316 steel prevents rust in damp mining conditions.

  • Rainy-Region Wheat Elevators: Applied to elevator access panels, IP67 handles heavy rainfall, and multi-voltage compatibility matches 230V AC elevator motors.

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