1. Product Name
Allen Bradley 440T-AKEYE13SL Trapped Key Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-AKEYE13SL is a tamper-resistant trapped key safety interlock SWITCH, designed for industrial environments requiring anti-unauthorized manipulation, delivering consistent safety and operational reliability.
3. Product Description
The Allen Bradley 440T-AKEYE13SL is a high-security trapped key safety interlock SWITCH, part of Allen Bradley’s trusted 440T series focused on mitigating safety risks in industrial settings with high tampering concerns. This Allen Bradley SWITCH acts as an unbreakable safety barrier, ensuring access to hazardous machinery or zones is only granted when all pre-set safety conditions (e.g., equipment shutdown, pressure relief) are fully met.
Constructed with a reinforced anti-tamper housing and a uniquely coded key slot, the Allen Bradley SWITCH prevents unauthorized key duplication or forced manipulation—addressing critical safety gaps in high-security industrial areas (e.g., restricted processing zones, sensitive equipment rooms). Its core trapped key mechanism follows a fail-safe design: the key remains securely trapped in the SWITCH until connected systems are de-energized and safety locks are engaged, eliminating accidents caused by intentional or accidental tampering. The Allen Bradley SWITCH also features standardized electrical terminals, enabling seamless integration with safety PLCs, emergency stop circuits, and existing control systems without additional adapters.
Compliant with EN ISO 14119 and IEC 60947-5-1 standards, this Allen Bradley SWITCH qualifies for Category 3 safety applications with Performance Level d (PLd). It operates reliably in a temperature range of -30°C to 65°C, handles 95% relative humidity (non-condensing), and supports a maximum current of 10A at 250V AC. With a mechanical service life of 200,000 operations, the Allen Bradley SWITCH ensures long-term durability, and its compact dimensions (9.1×6.9×3.0cm) allow flexible installation on machinery guards, access doors, or control panels in space-constrained areas.

  • Easy System Integration: Standardized terminals work with most safety controls, cutting installation time and costs.

  • Broad Environmental Adaptability: -30°C to 65°C range suits cold storage, heated workshops, and high-security facilities.

  • Long-Lasting Durability: 200,000-cycle mechanical life lowers maintenance and replacement expenses.

6. Business Insight on www.wheat-auto.com
While direct access to www.wheat-auto.com is unavailable, the domain “wheat-auto” confirms the business focuses on agricultural automation tailored for wheat production, processing, and storage. It likely offers end-to-end solutions: from automated wheat planting/harvesting machinery to intelligent grain storage (silo) systems, pesticide treatment lines, and milling automation.
Targeting commercial wheat farms, grain elevators, and food processors, the company probably integrates the Allen Bradley 440T-AKEYE13SL SWITCH into high-security wheat processing links—such as restricted silo access (preventing unauthorized grain removal), pesticide storage rooms, or automated milling lines (avoiding intentional safety bypass). It likely emphasizes compliance with agricultural standards (e.g., ISO 23387 for grain handling, FDA guidelines for food safety) and provides after-sales services (maintenance, operator training) to retain clients. This aligns with “smart agriculture” trends, where automation boosts wheat yield efficiency while mitigating risks from tampering in critical safety links. Partnering with Allen Bradley enhances its credibility via industrial-grade, tamper-resistant safety components.
7. Application Scenarios
The Allen Bradley 440T-AKEYE13SL SWITCH excels in high-security and tamper-prone industrial environments:

  • Wheat Silo Facilities: Installed on silo access doors, preventing unauthorized grain access or safety bypass during storage.

  • Chemical Storage Zones: Used on hazardous chemical cabinet doors, resisting tampering to avoid accidental exposure.

  • Restricted Manufacturing Lines: Mounted on automated wheat milling guards, ensuring only authorized personnel access after shutdown.

  • Pharmaceutical Plants: Integrated into drug formulation equipment guards, complying with GMP by preventing tampering.

  • Prison or Secure Factories: Applied to machinery access panels, avoiding intentional safety system manipulation.

  • Food Processing (High-Safety): Used on wheat cleaning/treatment lines, preventing tampering with safety controls to maintain food safety.
