1. Product Name
Allen Bradley 440T-ASCBS14LK Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-ASCBS14LK is an IP67-rated safety interlock SWITCH with 316 stainless steel construction, engineered for agri-industrial environments with dust, moisture, and mild chemicals—ideal for wheat farms and grain-processing facilities.
3. Product Description
The Allen Bradley 440T-ASCBS14LK is a robust safety interlock SWITCH, part of Allen Bradley’s 440T series designed to address safety risks in high-challenge agri-industrial settings. This Allen Bradley SWITCH acts as a mandatory safety barrier, allowing access to hazardous zones (e.g., wheat pesticide storage, grain silo conveyors) only when equipment is fully shut down, chemicals are neutralized, or dust concentrations reach safe levels.
Crafted with 316 stainless steel, the Allen Bradley SWITCH resists corrosion from wheat pesticides, ammonia-based fertilizers, and mild industrial solvents—solving a common pain point in agricultural chemical handling. Its sealed housing achieves IP67 protection, blocking 100% dust ingress and withstanding temporary submersion (up to 1 meter for 30 minutes), making it suitable for damp grain silos or outdoor wheat washing stations. A key design upgrade is its anti-clog terminal ports, which prevent grain dust or fertilizer residues from disrupting electrical connectivity—critical for consistent performance in dusty wheat processing lines. The Allen Bradley SWITCH supports 24V DC (for solar-powered farm equipment) and 110V/230V AC (for grid-powered industrial machines), enabling seamless integration without custom wiring.
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 temperatures ranging from -40°C (Arctic wheat storage) to 70°C (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: Blocks full dust ingress and temporary submersion, ideal for damp silos and outdoor agri-equipment.

  • 316 Stainless Steel Corrosion Resistance: Withstands wheat pesticides, fertilizers, and mild solvents—avoids rust in chemical-handling zones.

  • Wide Temperature Adaptability: -40°C to 70°C range suits extreme climates, from Arctic grain storage to desert wheat farms.

  • Anti-Clog Terminals: Prevents grain dust/fertilizer buildup, ensuring stable electrical connectivity in dusty processing environments.

  • 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—specializing in end-to-end solutions for commercial wheat farms, grain elevators, and food processors. Its core offerings likely include automated wheat harvesters, grain silo control systems, pesticide handling equipment, and conveyor safety setups.
The Allen Bradley 440T-ASCBS14LK aligns perfectly 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 maintenance for 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-ASCBS14LK SWITCH excels in agri-industrial environments with dust, moisture, and chemicals:

  • Wheat Pesticide Storage Tanks: Installed on tank access guards, 316 stainless 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.

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

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

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

  • Wheat Flour Mills: Used on flour sifter guards, anti-clog terminals prevent flour buildup from disrupting electrical performance.
