1. Product Name
Allen Bradley 440T - AKEYE103ADZ Safety Key Interlock Switch
2. Product Introduction
As a critical safety - focused product under Allen Bradley—a renowned global leader in industrial automation owned by Rockwell Automation—the 440T - AKEYE103ADZ is a high - performance safety key interlock switch. It carries forward Allen Bradley’s long - standing reputation for reliability and safety, designed to mitigate operational hazards in industrial settings, protect workers and equipment, and meet international safety standards for broad industry application.
3. Product Description
The Allen Bradley 440T - AKEYE103ADZ is a premium member of the Allen Bradley SWITCH lineup, engineered to prioritize industrial safety and deliver consistent performance. Its housing features a compact yet sturdy structure, crafted from high - grade industrial thermoplastic. This material provides strong resistance to impact, abrasion, and chemical corrosion, allowing the switch to endure harsh industrial environments—whether facing accidental collisions from heavy machinery in manufacturing plants or exposure to cleaning agents in food processing facilities.
With an IP65 ingress protection rating, the switch effectively blocks dust and low - pressure water jets. This makes it ideal for metalworking workshops with excessive metal shavings and beverage bottling plants that require frequent equipment cleaning to maintain hygiene. Functionally, it operates via a precise key - interlocking mechanism: only when an authorized key is inserted and turned can the power supply or control circuits of connected industrial equipment be activated or deactivated. For instance, in a warehouse conveyor system, the switch can be mounted on the access door of the drive unit. Maintenance staff must use the key to cut off the conveyor’s power before opening the door, eliminating the risk of accidental startup and potential worker injuries.
The switch adopts a positive - opening contact design that complies with the international safety standard IEC 60947 - 5 - 1, preventing dangerous closed - state failures even if internal components wear over time. It also supports unique key coding, ensuring each key only works with its matching switch to restrict unauthorized access. Installation is flexible, supporting both horizontal and vertical mounting, and it is fully compatible with Allen Bradley control systems (such as the Logix series), enabling seamless integration without extensive system modifications. Boasting a mechanical life of up to 1,000,000 operations and the ability to withstand temperatures ranging from - 25°C to + 70°C, the switch delivers long - term reliable performance.
