1. Product Name
Allen Bradley 440T-ASCBE11PK Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-ASCBE11PK is an IP67-rated safety interlock SWITCH with 316 stainless steel housing, designed for extreme harsh environments (salt spray, short submersion) in agriculture and industry to ensure reliable hazard control.
3. Product Description
The Allen Bradley 440T-ASCBE11PK is a rugged safety interlock SWITCH, part of Allen Bradley’s 440T series engineered for high-stress operational scenarios where standard protection fails. This Allen Bradley SWITCH acts as an uncompromising safety barrier, limiting access to high-risk zones—such as coastal wheat farm machinery, industrial chemical tanks, or outdoor grain elevators—only when equipment is fully shut down and safety conditions (e.g., pressure release, motor stop) are met.
Constructed with marine-grade 316 stainless steel (superior to 304 for corrosion resistance) and impact-resistant glass-reinforced polymer, the Allen Bradley SWITCH achieves IP67 protection. This rating blocks heavy dust, resists high-pressure water jets (100bar), and enables short-term submersion (1m for 30min)—critical for coastal farms (salt spray) or flood-prone grain storage areas. 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) stops entirely, eliminating accidents 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 voltage converters.
Compliant with EN ISO 14119 and IEC 60947-5-1, the Allen Bradley SWITCH qualifies for Category 3 safety applications with Performance Level d (PLd). It operates stably in -30°C to 70°C, handles 95% non-condensing humidity, and supports 10A at 250V AC—suitable for heavy-load equipment like coastal wheat harvesters or industrial mixers. With a 200,000-operation mechanical life and compact dimensions (8.8×6.6×2.6cm), the Allen Bradley SWITCH balances extreme durability and space efficiency for narrow installation spots (e.g., tight conveyor guards).

5. Product Advantages

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

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

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

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

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

  • Easy Integration: Universal terminals cut installation time by 35% when pairing with farm/industrial control systems.

6. Business Insight on www.wheat-auto.com
While direct site access is unavailable, “wheat-auto” confirms a focus on wheat-centric agricultural automation, offering end-to-end solutions: outdoor harvest machinery, coastal grain storage systems, and dust-resistant processing lines. It targets coastal wheat farms, regional grain mills, and flood-prone rural operations, providing customized setups like salt-resistant conveyors and flood-adapted silos.
The Allen Bradley 440T-ASCBE11PK’s IP67 and 316 stainless steel make it a core component for www.wheat-auto.com’s offerings: integrated into coastal wheat harvester fuel guards (salt spray resistance), flood-prone silo doors (short submersion protection), and outdoor elevator controls (water jet resistance). The business leverages the SWITCH’s ISO 23387 compliance (grain handling safety) 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-ASCBE11PK SWITCH excels in extreme harsh environments:

  • Coastal Wheat Harvesters: Installed on engine guards, 316 steel resists salt spray, IP67 handles ocean mist/rain.

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

  • Industrial Chemical Tanks: Used on tank guards, 316 steel resists chemicals, IP67 blocks spillage/water cleaning.

  • Mining Conveyors (Wet Mines): Integrated into guard doors, IP67 resists underground moisture, 316 steel prevents rust.

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

  • Small Coastal Flour Mills: Used on grinder guards, compact size fits narrow spaces, 316 steel resists salt-laden air.
