1. Product Name
Allen Bradley 440T-ASCBS14GA Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-ASCBS14GA is an IP67-rated safety interlock SWITCH with 316 stainless steel, built for agri-industrial settings with chemicals, dust, and moisture—ideal for wheat farms and chemical-processing zones.
3. Product Description
The Allen Bradley 440T-ASCBS14GA is a rugged safety interlock SWITCH, part of Allen Bradley’s 440T series tailored for high-risk agri-industrial environments where standard switches fail. This Allen Bradley SWITCH acts as a critical safety barrier, permitting access to hazardous zones (e.g., wheat pesticide tanks, grain dust chambers) only when machinery halts, chemicals are drained, or dust levels drop to safe limits.
Crafted with 316 stainless steel (resistant to wheat pesticides, ammonia fertilizers, and mild industrial solvents) and a sealed housing, the Allen Bradley SWITCH achieves IP67 protection—blocking dust ingress and withstanding temporary submersion (up to 1m for 30 minutes), solving pain points in damp grain silos or chemical spill-prone areas. Its key design feature is dust-tight terminal chambers, which prevent grain dust accumulation from disrupting electrical connectivity—a common issue in wheat processing. The Allen Bradley SWITCH supports 24V DC/110V AC/230V AC voltages, seamlessly integrating with solar-powered wheat farm equipment and grid-powered chemical mixers.
Compliant with EN ISO 14119 and IEC 60947-5-1, this Allen Bradley SWITCH meets Category 3 safety standards with Performance Level d (PLd). It operates reliably in temperatures from -40°C to 70°C (suiting Arctic wheat storage and desert harvesting), handles 95% non-condensing humidity, and supports 10A current at 250V AC for high-load machinery. With a 300,000-operation mechanical life and compact dimensions (8.8×6.5×2.6cm), the Allen Bradley SWITCH balances durability and space efficiency for tight installations like pesticide tank guards.

5. Product Advantages

  • IP67 Dust & Water Resistance: Blocks full dust ingress and temporary submersion, perfect for damp silos and chemical spill zones.

  • 316 Stainless Steel Durability: Resists wheat pesticides and fertilizers, avoiding corrosion that shortens switch life in agri-settings.

  • Wide Temperature Range: -40°C to 70°C adapts to Arctic wheat storage (cold) and desert harvesting (heat) without performance loss.

  • Dust-Tight Terminals: Prevents grain dust buildup, ensuring stable connectivity in dusty wheat processing lines.

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

  • Long Mechanical Life: 300,000 operations reduce replacement frequency, cutting maintenance costs for high-use agri-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—specializing in solutions like automated harvesters, grain silo controls, and pesticide handling systems for commercial wheat farms.
The Allen Bradley 440T-ASCBS14GA aligns perfectly with its offerings: its 316 stainless steel resists pesticide corrosion (critical for wheat farm chemical tanks), and IP67 protects against damp silo conditions. The site likely integrates this SWITCH into key equipment—pesticide mixing tank guards (preventing access until empty), grain conveyor safety gates (blocking dust damage), and silo access panels (withstanding occasional moisture). It would leverage the SWITCH’s compliance with ISO 23387 (grain handling safety) to meet agricultural standards, and offer farm-specific support (e.g., dust-cleaning maintenance) to address rural operational challenges. This ties to “smart agriculture” trends, using the Allen Bradley SWITCH to enable safe, efficient wheat production in harsh on-farm environments.
7. Application Scenarios
The Allen Bradley 440T-ASCBS14GA SWITCH excels in agri-industrial settings with chemicals, dust, and moisture:

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

  • Grain Silo Conveyors: Mounted on conveyor gates, IP67 blocks dust and dampness—ensures safety during grain loading/unloading.

  • Chemical Fertilizer Zones (Wheat Farms): Used on fertilizer storage doors, 316 steel withstands ammonia fumes without rusting.

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

  • Mining Grain Transport: Integrated into mineral-grain mixer guards, 316 steel resists mine dust and mild chemicals.

  • Food Processing (Wheat Flour): Used on flour mill guards, dust-tight terminals prevent flour buildup from disrupting operation.
