1. Product Name
Allen Bradley 440T-AKEYS10GL Trapped Key Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-AKEYS10GL is an IP66/chemical-resistant trapped key safety interlock SWITCH, engineered for harsh industrial environments with chemical exposure, dust, and high-pressure water.
3. Product Description
The Allen Bradley 440T-AKEYS10GL is a heavy-duty trapped key safety interlock SWITCH, part of Allen Bradley’s trusted 440T series dedicated to hazard prevention in chemically aggressive settings. This Allen Bradley SWITCH acts as a critical safety barrier, ensuring access to hazardous zones (e.g., chemical tanks, pesticide-treated grain areas) is only allowed when equipment is fully safe.
Constructed with chemical-resistant polymer and stainless steel components, the Allen Bradley SWITCH achieves IP66 protection—blocking dust ingress and withstanding high-pressure water jets (up to 100bar). Its core trapped key mechanism follows a fail-safe design: the key remains trapped in the SWITCH until connected systems are de-energized, chemical residues are neutralized, or pressure is relieved, eliminating accident risks from premature access. The Allen Bradley SWITCH features universal 24V DC/230V AC terminals, enabling seamless integration with safety PLCs and emergency stop circuits without custom modifications.
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 in -30°C to 65°C temperatures, handles 95% non-condensing humidity, and supports 10A/250V AC current. With a 200,000-operation mechanical life and compact size (8.9×6.7×2.8cm), the Allen Bradley SWITCH balances durability and space efficiency for tight installations.

6. Business Insight on www.wheat-auto.com
While direct access is unavailable, “wheat-auto” confirms focus on wheat-centric agricultural automation—offering end-to-end solutions from planting/harvesting to grain processing/storage. The business likely designs systems for wheat farms, elevators, and food plants, integrating equipment like pesticide sprayers, grain cleaners, and silo controls.
Given 440T-AKEYS10GL’s chemical resistance, www.wheat-auto.com would incorporate this Allen Bradley SWITCH into pesticide-treated grain areas or chemical storage zones of wheat processing lines—leveraging IP66 protection for washdowns and chemical resilience for pesticide residues. It probably offers agriculture-specific support: compliance with ISO 23387 (grain handling), maintenance for harsh farm environments, and safety training. This aligns with “smart agriculture” trends, using automation to boost wheat yield while ensuring safety; partnering with Allen Bradley enhances credibility via industrial-grade components.
7. Application Scenarios
The Allen Bradley 440T-AKEYS10GL SWITCH excels in chemically aggressive, harsh environments:

  • Wheat Pesticide Zones: Installed on treated grain storage doors, resisting pesticide residues and washdowns.

  • Chemical Plants: Used on solvent tank access panels, chemical-resistant build withstands corrosive fumes.

  • Food Processing (Cleaning Zones): Mounted on wheat washer guards, IP66 handles high-pressure sanitizing sprays.

  • Mining (Chemical Dust): Integrated into ore conveyor gates, resisting acid/alkali dust in mineral processing.

  • Agricultural Spray Equipment: Applied to pesticide tank lids, ensuring safe access after chemical emptying.

  • Pharmaceutical Facilities: Used on API storage doors, chemical resistance and IP66 meet sterile/hazardous standards.
