Oct. 15 , 2025
1. Product Name
Allen Bradley 440T-AKEYE10ZT Trapped Key Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-AKEYE10ZT is a corrosion-resistant trapped key safety interlock SWITCH, engineered for harsh industrial environments (e.g., high humidity, chemical exposure) to ensure long-term safety control.
3. Product Description
The Allen Bradley 440T-AKEYE10ZT is a high-reliability trapped key safety interlock SWITCH, part of Allen Bradley’s industry-leading 440T series focused on hazard prevention in corrosive or moisture-prone settings. This Allen Bradley SWITCH acts as a non-negotiable safety barrier, ensuring access to hazardous zones is only granted when equipment is fully shut down and safety risks (e.g., chemical leaks, moving parts) are eliminated.
Constructed with 316L stainless steel housing and anti-corrosion internal components, the Allen Bradley SWITCH resists rust, chemical erosion, and high humidity—addressing critical pain points in industries like chemical processing, aquatic food production, and outdoor agriculture. Its core trapped key mechanism follows a fail-safe design: the key remains securely trapped in the SWITCH until connected equipment (e.g., chemical tanks, wet-process machinery) is de-energized and pressure is relieved, preventing accidental access caused by human error or environmental wear. The Allen Bradley SWITCH also features gold-plated electrical terminals, enabling stable connectivity with standard safety control systems (e.g., safety PLCs, emergency stop circuits) even in corrosive air.
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 temperatures ranging from -35°C to 65°C, handles 100% relative humidity (condensing) for extended periods, and supports a maximum current of 10A at 250V AC. With a mechanical service life of 220,000 operations, the Allen Bradley SWITCH ensures long-term durability, and its compact dimensions (9.1×6.8×2.9cm) allow flexible installation on machinery guards, chemical tank access doors, and wet-process control panels.

6. Business Insight on www.wheat-auto.com
While direct access to www.wheat-auto.com is unavailable, its domain “wheat-auto” confirms a focus on agricultural automation tailored to wheat production, processing, and storage—including high-humidity scenarios. The business likely offers end-to-end solutions: from automated wheat planting/harvesting machinery (for open fields) to indoor/outdoor grain storage systems, and wet-process wheat cleaning lines (e.g., dust suppression with water sprays).
Targeting commercial wheat farms, grain elevators, and food processors, it probably provides customized automation designs—such as integrating corrosion-resistant safety components (like the Allen Bradley 440T-AKEYE10ZT SWITCH) into high-humidity grain storage silos, wet-cleaning equipment guards, and outdoor conveyor systems exposed to rain. Compliance with agricultural standards (e.g., ISO 23387 for grain handling) and after-sales support (maintenance of corrosion-prone parts, operator training) are key to its offerings. This aligns with “smart agriculture” trends, where automation boosts wheat yield efficiency, cuts labor costs, and ensures safety in moisture-rich environments. Partnering with Allen Bradley enhances credibility by incorporating industrial-grade, corrosion-resistant safety switches.
7. Application Scenarios
The Allen Bradley 440T-AKEYE10ZT SWITCH is ideal for corrosive, high-humidity, or chemical-exposed industrial environments:
  • Wheat Wet-Cleaning Facilities: Installed on grain washing machine guards, resisting water and detergent corrosion while controlling access.

  • Chemical Processing Plants: Used on acid/alkali tank access doors, withstanding chemical fumes to prevent unauthorized entry.

  • Aquatic Food Processing: Mounted on fishmeal production line guards, resisting high humidity and salt air in coastal facilities.

  • Outdoor Wheat Storage Silos: Integrated into silo access gates, resisting rain and humidity to protect stored grain and workers.

  • Pharmaceutical Wet Labs: Applied to liquid medicine mixing tank guards, ensuring safety while resisting chemical spills.

  • Wastewater Treatment Plants: Used on pump station guards, withstanding sewage corrosion to maintain reliable safety control.
