Oct. 17 , 2025
1. Product Name
Allen Bradley 440T-ASCBE14LH Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-ASCBE14LH is an IP66-rated safety interlock SWITCH with 316 stainless steel housing, optimized for low-temperature agri-industrial environments to resist corrosion, dust, and freezing conditions.
3. Product Description
The Allen Bradley 440T-ASCBE14LH is a robust safety interlock SWITCH, part of Allen Bradley’s 440T series designed to tackle extreme low-temperature and harsh operational challenges: frigid wheat farms, cold-storage grain silos, and icy industrial sites. This Allen Bradley SWITCH acts as a critical safety barrier, allowing access to hazardous zones—such as winter wheat harvesters, frozen grain storage units, or cold-region chemical facilities—only when machinery is fully powered off and safety prerequisites (e.g., motion cessation, pressure relief) are satisfied.
Crafted with 316 stainless steel housing (superior to 304 in corrosion resistance, ideal for icy salted surfaces or cold chemical exposure) and freeze-resistant industrial polymer internals, the Allen Bradley SWITCH achieves IP66 protection. This rating ensures complete dust tightness and resistance to high-pressure water jets (up to 100bar), making it suitable for winter washdowns, icy grain handling, or cold coastal harvests. Its core interlock mechanism features a anti-freeze dual-latch design, optimized to withstand intense vibration (up to 50Hz) and prevent lock seizure in sub-zero temperatures—essential for heavy-duty equipment like winter wheat combine harvesters. With broad voltage compatibility (24V DC/110V AC/230V AC), the Allen Bradley SWITCH integrates seamlessly with large agricultural machinery controls (e.g., cold-region harvester safety circuits) and industrial-grade safety PLCs, via flame-retardant terminal blocks that reduce installation time and fire risks.
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 reliably in temperatures from -40°C to 70°C, handles 95% non-condensing humidity (even in freeze-thaw cycles), and supports a maximum current of 10A at 250V AC—perfect for high-load equipment like cold-storage silo doors or icy conveyor systems. With a mechanical service life of 250,000 operations and compact dimensions (8.5×6.2×2.4cm), the Allen Bradley SWITCH balances extreme low-temperature durability, corrosion resistance, and space efficiency for tight installation spots (e.g., harvester engine guards or cold-silo access panels).

5. Product Advantages
  • Low-Temp Resilience: -40°C operational range prevents lock seizure, ideal for frigid wheat farms and cold-storage silos.

  • Superior Corrosion Resistance: 316 stainless steel housing withstands icy salted surfaces and cold chemical fumes in harsh agri-industrial zones.

  • IP66 Heavy-Duty Protection: Blocks full dust ingress and 100bar water jets, reliable for winter washdowns or icy harvests.

  • Intense Vibration Stability: Anti-freeze dual-latch design resists 50Hz vibration, avoiding false unlocks on winter machinery.

  • Multi-Voltage Compatibility: Works with 24V DC/110V AC/230V AC systems, matching cold-region agri-industrial power configurations.

  • Cost-Effective Durability: 250,000-cycle life and freeze-resistant materials reduce replacement/maintenance costs in low-temp environments.

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, specializing in solutions for low-temperature and harsh winter wheat operations—frigid farms, cold-storage grain silos, and icy coastal harvest sites. It targets commercial wheat operations facing freeze-related challenges, offering tailored systems like winterized combine harvesters, temperature-controlled silos, and icy-conveyor safety networks.
The Allen Bradley 440T-ASCBE14LH’s -40°C low-temp resilience and 316 steel corrosion resistance make it a key component in the site’s offerings: integrated into winter wheat harvester fuel tank guards (to resist icy salt spray), cold-storage silo access doors (to prevent lock seizure), and icy conveyor guards (to withstand freeze-thaw cycles). The business leverages the SWITCH’s compliance with ISO 23387 (grain handling safety) and EN 60529 (IP66) to ensure reliability in winter wheat operations. It likely provides cold-specific after-sales services, such as anti-freeze lubrication checks and low-temp performance testing, to address frigid rural needs. This aligns with “smart agriculture” trends, using industrial-grade Allen Bradley SWITCHes to maintain wheat production efficiency even in extreme winter conditions.
7. Application Scenarios
The Allen Bradley 440T-ASCBE14LH SWITCH excels in low-temperature, harsh agri-industrial environments:
  • Winter Wheat Combine Harvesters: Installed on engine guards, -40°C resilience prevents lock seizure, and 316 steel resists icy salt spray—ensuring access only after shutdown.

  • Cold-Storage Grain Silos: Mounted on silo doors, freeze-resistant internals avoid lock failure during long-term frozen grain storage.

  • Icy Coastal Wheat Farms: Used on pesticide storage guards, 316 steel resists salted icy surfaces, and IP66 blocks winter dust/rain.

  • Winter Grain Wash Zones: Applied to wheat cleaner guards, IP66 withstands high-pressure de-icing jets in cold washdown facilities.

  • Cold-Region Mining Conveyors: Integrated into ore conveyor guards, low-temp resilience avoids freeze-related malfunctions in icy mines.

  • Frozen Food Processing: Used on wheat flour storage doors in cold facilities, humidity resistance prevents moisture buildup and lock corrosion.
