Oct. 14 , 2025
1. Product Name
Allen Bradley 440T - AKEYE103ABG Safety Key Interlock Switch
2. Product Introduction
As a core safety product under Allen Bradley, a leading brand in global industrial automation owned by Rockwell Automation, the 440T - AKEYE103ABG is a high - performance safety key interlock switch. It inherits Allen Bradley’s legacy of reliability and safety, designed to eliminate industrial operational hazards, protect workers and equipment, and comply with international safety standards for wide application.
3. Product Description
The Allen Bradley 440T - AKEYE103ABG is a high - quality member of the Allen Bradley SWITCH family, engineered for industrial safety and stable performance. Its housing adopts a compact and robust structure, made of premium industrial - grade thermoplastic. This material offers strong resistance to impact, abrasion, and chemical corrosion, enabling the switch to withstand harsh industrial environments—such as accidental collisions from heavy machinery in manufacturing plants or exposure to cleaning agents in food processing facilities.
Equipped with an IP65 ingress protection rating, the switch effectively blocks dust and low - pressure water jets. This makes it suitable for metalworking workshops with abundant metal shavings and beverage bottling plants that require regular equipment cleaning. Functionally, it relies on a precise key - interlocking mechanism: only when an authorized key is inserted and turned can the power supply or control circuits of connected equipment be activated or deactivated. For example, in a warehouse conveyor system, the switch can be installed 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, avoiding accidental startup and potential injuries.
The switch features a positive - opening contact design compliant with IEC 60947 - 5 - 1, preventing dangerous closed - state failures even if internal parts wear. It also supports unique key coding, ensuring each key only works with its matched switch to block unauthorized access. Installation is flexible (horizontal/vertical mounting) and compatible with Allen Bradley control systems (e.g., Logix series), enabling easy integration without extensive modifications. With a mechanical life of up to 1,000,000 operations and resistance to - 25°C to + 70°C temperatures, it delivers long - term reliable performance.
