1. Product Name
Allen Bradley 440T-ASCBS14YN Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-ASCBS14YN is an IP67-rated safety interlock SWITCH with 316 stainless steel construction, tailored for agri-industrial environments (wheat farms, grain mills) to resist dust, moisture, and mild agricultural chemicals.
3. Product Description
The Allen Bradley 440T-ASCBS14YN is a high-durability safety interlock SWITCH, part of Allen Bradley’s 440T series engineered to mitigate safety risks in harsh agri-industrial settings. This Allen Bradley SWITCH acts as a mandatory safety barrier, permitting access to hazardous zones (e.g., wheat pesticide tanks, grain silo conveyors) only when equipment is fully shut down, chemical residues are cleared, or dust levels drop to safe thresholds.
Crafted from 316 stainless steel, the Allen Bradley SWITCH delivers exceptional corrosion resistance against wheat pesticides, ammonia-based fertilizers, and mild industrial solvents—addressing a key pain point in agricultural chemical handling. Its sealed housing achieves IP67 protection, blocking 100% dust ingress and withstanding temporary submersion (1 meter for 30 minutes), making it ideal for damp grain silos or outdoor wheat washing stations. A standout design feature is its anti-clog terminal ports, which prevent grain dust, flour residues, or fertilizer particles from disrupting electrical connectivity—ensuring consistent performance in high-dust wheat processing lines. The Allen Bradley SWITCH supports dual voltage inputs (24V DC for solar-powered farm equipment, 110V/230V AC for grid-powered industrial machines), enabling seamless integration without custom wiring modifications.
Compliant with EN ISO 14119 and IEC 60947-5-1 standards, this Allen Bradley SWITCH meets Category 3 safety requirements with Performance Level d (PLd). It operates reliably in extreme temperatures (-40°C for Arctic wheat storage to 70°C for desert wheat harvesting), handles 95% non-condensing humidity, and supports a maximum current of 10A at 250V AC for high-load machinery. With a mechanical service life of 300,000 operations and compact dimensions (8.7×6.4×2.5cm), the Allen Bradley SWITCH balances long-term durability and space efficiency for tight installations like pesticide tank guards or silo access panels.

5. Product Advantages

  • IP67 All-Weather Protection: Shields against full dust ingress and temporary submersion, perfect for damp silos and outdoor agri-equipment.

  • 316 Stainless Steel Durability: Resists corrosion from wheat pesticides/fertilizers, avoiding rust in chemical-handling zones.

  • Extreme Temperature Adaptability: -40°C to 70°C range suits polar grain storage and desert wheat harvesting.

  • Anti-Clog Terminals: Prevents grain dust/fertilizer buildup, ensuring stable electrical performance in dusty mills.

  • Dual-Voltage Compatibility: Works with 24V DC (solar) and 110V/230V AC (grid), fitting diverse farm/industrial power setups.

  • Long Service Life: 300,000 mechanical operations reduce replacement frequency, cutting maintenance costs for high-use equipment.

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 for commercial wheat farms, grain elevators, and food processors (e.g., automated harvesters, silo control systems, pesticide handling equipment).
The Allen Bradley 440T-ASCBS14YN aligns seamlessly with its product ecosystem: its 316 stainless steel resists corrosion from wheat pesticides (critical for farm chemical tanks), and IP67 protection withstands damp silo conditions. The site would integrate this SWITCH into key safety points—pesticide tank access guards (preventing exposure until tanks are empty), grain conveyor gates (blocking dust damage), and outdoor wheat washer panels (withstanding rain). It would leverage the SWITCH’s compliance with ISO 23387 (grain handling safety standards) to meet agricultural regulations, and offer farm-specific after-sales support (e.g., dust-cleaning for anti-clog terminals) to address rural operational challenges. This ties to “smart agriculture” trends, using industrial-grade Allen Bradley SWITCHes to boost wheat production efficiency while ensuring worker safety in harsh on-farm environments.
7. Application Scenarios
The Allen Bradley 440T-ASCBS14YN SWITCH excels in agri-industrial environments with dust, moisture, and chemicals:

  • Wheat Pesticide Storage Tanks: Installed on tank access guards, 316 steel resists pesticide corrosion—unlocks only when tanks are drained.

  • Grain Silo Conveyors: Mounted on conveyor safety gates, IP67 blocks dust and silo dampness—ensures access only after conveyor stops.

  • Wheat Farm Fertilizer Bins: Used on bin doors, 316 steel withstands ammonia fumes without rusting, maintaining long-term safety.

  • Outdoor Wheat Cleaning Lines: Applied to washer equipment guards, IP67 handles rain and grain dust during open-air cleaning.

  • Grain Flour Mills: Integrated into flour sifter guards, anti-clog terminals prevent flour buildup from disrupting electrical performance.

  • Agricultural Chemical Mixing Zones: Used on mixing tank guards, 316 steel resists chemical spills, ensuring safe access post-mixing.
