1. Product Name
Allen Bradley 440T-ASCBE143CBV Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-ASCBE143CBV is an IP67-rated safety interlock SWITCH with 316L stainless steel housing, designed to resist corrosion and vibration for reliable performance in harsh agricultural and industrial environments.
3. Product Description
The Allen Bradley 440T-ASCBE143CBV is a robust safety interlock SWITCH, part of Allen Bradley’s 440T series engineered to address key pain points in high-stress operations: corrosive substances and persistent mechanical vibration. This Allen Bradley SWITCH acts as a critical safety barrier, permitting access to hazardous zones—such as vibrating wheat combine harvesters, moisture-prone grain silos, or chemical processing equipment—only when machinery is fully shut down and safety conditions (e.g., vibration cessation, pressure relief) are met.
Constructed with thick 316L stainless steel (superior to standard stainless steel in corrosion resistance) and shock-absorbing industrial polymer, the Allen Bradley SWITCH achieves IP67 protection. This rating allows it to withstand high-pressure water jets (up to 80bar), block 100% dust ingress, and endure temporary submersion (1 meter for 30 minutes)—perfect for rainy wheat harvests, dusty flour mills, or industrial sites requiring frequent cleaning. Its core interlock mechanism features a reinforced double-latch design, specifically built to resist loosening under extreme vibration (up to 50Hz), preventing accidental unlocks that could lead to safety incidents. Compatible with 12V DC/24V DC/230V AC power systems, the Allen Bradley SWITCH integrates seamlessly with agricultural machinery controls (e.g., combine harvester safety circuits) and industrial safety PLCs, thanks to anti-loosen terminal blocks that reduce the need for frequent re-adjustment.
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 -35°C to 75°C, handles 95% non-condensing humidity, and supports a maximum current of 10A at 250V AC—suitable for medium-to-heavy-load equipment like large wheat cleaners or industrial mixing tanks. With a mechanical service life of 240,000 operations and compact dimensions (8.7×6.5×2.5cm), the Allen Bradley SWITCH balances durability, vibration resistance, and space efficiency for tight installation spots, such as harvester engine bays or conveyor joint guards.

5. Product Advantages

  • Exceptional Corrosion Resistance: 316L stainless steel housing withstands salt air, agricultural chemicals, and industrial cleaners, extending service life.

  • IP67 Harsh-Environment Protection: Resists high-pressure water, full dust ingress, and temporary submersion—reliable in rainy or dusty workplaces.

  • Strong Vibration Resistance: Reinforced double-latch design resists 50Hz vibration, avoiding false unlocks in combine harvesters or heavy conveyors.

  • Wide Voltage Compatibility: Works with 12V DC/24V DC/230V AC systems, matching diverse agri-industrial power setups without converters.

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

  • Low Maintenance Needs: Anti-loosen terminals and corrosion-resistant materials reduce re-calibration and replacement frequency, cutting 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 vibration-prone combine harvesters and moisture-sensitive grain silos to dusty flour processing lines. It targets high-intensity wheat operations—rain-prone farms, inland grain elevators, and industrial flour mills—where corrosion and vibration threaten equipment safety.
The Allen Bradley 440T-ASCBE143CBV’s 316L steel and vibration-resistant latch make it a core component of www.wheat-auto.com’s offerings: integrated into combine harvester engine guards (to handle harvest vibration), grain silo access doors (to resist moisture corrosion), and flour cleaner panels (to block dust). The business leverages the SWITCH’s compliance with ISO 23387 (grain handling safety standards) to ensure reliability during peak harvests or harsh weather. It likely provides farm-specific after-sales services, such as corrosion inspections and vibration testing, to address rural operational challenges. This aligns with “smart agriculture” trends, using durable Allen Bradley SWITCHes to boost wheat production efficiency while minimizing safety risks from harsh conditions.
7. Application Scenarios
The Allen Bradley 440T-ASCBE143CBV SWITCH excels in corrosion-prone and high-vibration environments:

  • Wheat Combine Harvesters: Installed on engine guards, the vibration-resistant latch stays secure during harvest, while IP67 blocks rain and dust.

  • Inland Grain Silos: Mounted on access doors, 316L steel resists moisture corrosion from stored grain, ensuring long-term safety.

  • Flour Processing Mills: Used on cleaner guards, IP67 blocks flour dust, and corrosion-resistant housing withstands mild cleaning chemicals.

  • Mining Conveyors: Integrated into conveyor joint guards, vibration resistance handles heavy-load grain transport, and IP67 blocks mine dust.

  • Cold Wheat Storage: Applied to freezer silo doors, -35°C temperature resilience works reliably in winter cold-storage facilities.

  • Agricultural Chemical Tanks: Used on pesticide tank guards for wheat farms, 316L steel resists chemical corrosion, and IP67 prevents leaks from damaging the SWITCH.
