Overview
The Allen-Bradley 440S-MF5D is a GuardLink enabled tap designed for use in safety-critical industrial automation applications. This M12 5-pin EMSS (Electromechanical Safety Switch) connection tap serves as a quick-disconnect interface for safety input devices within a GuardLink system. GuardLink is a safety-based communications protocol that connects safety devices to Rockwell Automation’s Connected Enterprise architecture, enabling real-time visibility and diagnostics at the individual guard or e-stop level.
Key Features
- GuardLink Smart Technology: GuardLink taps connect safety input devices to a GuardLink system, a safety-based communications protocol that links safety to The Connected Enterprise.
- Advanced Diagnostics: Real time, contextual diagnostics and sensor health data significantly improve troubleshooting and enable predictive maintenance planning.
- M12 5-Pin Female Connector: Micro-style M12 receptacle for EMSS (Electromechanical Safety Switch) contact devices.
- Quick-Disconnect Design: Part of the Guardmaster quick-disconnect safety connection system for simplified installation and maintenance.
- Industrial-Grade Construction: Red RAL 3020 unfilled ABS MG47C plastic case material for durability in harsh environments.
- Standards Compliance: Certified to CCC, CE, CUL, KC, RCM, and UL standards for global deployment.
