1. Product Name
Allen Bradley 440T-ASCBE14BR Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-ASCBE14BR is an IP66-rated safety interlock SWITCH with 304 stainless steel housing, designed to resist dust, moderate moisture, and mild corrosion for agricultural and industrial harsh settings.
3. Product Description
The Allen Bradley 440T-ASCBE14BR is a durable safety interlock SWITCH, part of Allen Bradley’s 440T series engineered to address common challenges in semi-harsh operations: heavy dust, occasional moisture, and light chemical exposure. This Allen Bradley SWITCH serves as a mandatory safety barrier, permitting access to hazardous zones—such as dry-region wheat harvesters, inland grain silos, or light-industry processing equipment—only when machinery is fully shut down and safety conditions (e.g., motion stop, pressure release) are met.
Constructed with 304 stainless steel housing (excellent for mild corrosion resistance) and impact-resistant industrial plastic components, the Allen Bradley SWITCH achieves IP66 protection. This rating enables it to block 100% dust penetration and withstand medium-pressure water jets (up to 50bar)—ideal for dry wheat harvests, dusty grain storage, or sites with occasional cleaning sprays. Its core interlock mechanism features a reliable single-latch design, optimized to resist loosening under moderate vibration (up to 30Hz), avoiding accidental unlocks that could lead to safety incidents. With broad voltage compatibility (24V DC/110V AC), the Allen Bradley SWITCH integrates seamlessly with agricultural machinery controls (e.g., wheat conveyor safety circuits) and small-to-medium industrial safety PLCs, via secure terminal blocks that minimize reconfiguration needs.
Compliant with EN ISO 14119 and IEC 60947-5-1 standards, the Allen Bradley SWITCH meets Category 3 safety requirements with Performance Level d (PLd). It operates stably in a temperature range of -25°C to 70°C, handles 90% non-condensing humidity, and supports a maximum current of 8A at 250V AC—suitable for light-to-medium-load equipment like small wheat silo doors or industrial packaging machines. With a mechanical service life of 200,000 operations and compact dimensions (8.2×6.0×2.2cm), the Allen Bradley SWITCH balances durability, environmental resistance, and space efficiency for tight installations (e.g., conveyor side guards or small harvester control panels).

5. Product Advantages

  • Reliable Corrosion Resistance: 304 stainless steel housing withstands light chemicals and inland humidity, extending service life in agri-industrial settings.

  • IP66 Protection: Blocks full dust ingress and medium-pressure water, reliable for dry/dusty or occasionally wet workplaces.

  • Moderate Vibration Resistance: Single-latch design resists 30Hz vibration, preventing false unlocks in conveyors or small harvesters.

  • Flexible Voltage Compatibility: Works with 24V DC/110V AC systems, matching most small-to-medium agri-industrial power setups.

  • Global Safety Compliance: PLd/Category 3 rating meets EN/IEC standards, reducing medium-risk accident risks in semi-harsh conditions.

  • Low-Upkeep Design: Corrosion-resistant materials and secure terminals minimize maintenance, cutting long-term operational costs.

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: from dry-region wheat harvesters and inland grain silos to small-scale flour processing lines. It targets wheat operations in semi-harsh environments—dry farming areas, inland grain storage facilities, and light-industry flour mills—where dust and occasional moisture are primary challenges.
The Allen Bradley 440T-ASCBE14BR’s IP66 dust resistance, 304 steel mild corrosion protection, and voltage flexibility make it a key component of www.wheat-auto.com’s offerings: integrated into dry-region harvester accessory guards (to handle harvest dust), inland silo access doors (to resist indoor humidity), and small wheat cleaner panels (to block flour particles). The business leverages the SWITCH’s compliance with ISO 23387 (grain handling safety standards) to ensure reliability during peak dry harvests or occasional cleaning. It likely provides tailored after-sales services, such as dust removal checks and terminal maintenance, to address rural operational needs. This aligns with “smart agriculture” trends, using cost-effective Allen Bradley SWITCHes to boost wheat production efficiency while mitigating semi-harsh environment risks.
7. Application Scenarios
The Allen Bradley 440T-ASCBE14BR SWITCH excels in dust-prone, semi-harsh agri-industrial environments:

  • Dry-Region Wheat Harvesters: Installed on harvester accessory guards, IP66 blocks harvest dust while ensuring access only after the machine stops.

  • Inland Grain Silos: Mounted on small silo access doors, 304 steel resists indoor humidity, maintaining safety during grain storage.

  • Small Flour Mills: Used on compact cleaner guards, IP66 blocks flour dust, and the switch’s small size fits tight equipment spaces.

  • Agricultural Machinery Repair Stations: Integrated into wheat tractor maintenance panels, moderate vibration resistance handles workshop tool operation.

  • Food Processing (Dry Zones): Applied to wheat-based cereal packaging machine guards, IP66 prevents product dust ingress into the switch.

  • Small-Scale Mining Conveyors: Used on light-load ore conveyor guards, dust resistance and 304 steel suit semi-harsh mining auxiliary areas.
