Keyence GS – 71N5 Safety Interlock Switch
Product Overview
The Keyence GS – 71N5 is an electromagnetic – locking safety interlock switch designed for industrial automation, ideal for securing machine guards, access panels, and safety gates in manufacturing and processing equipment. As a standard – type NPN output model with a 5 – meter 8 – core loose – wire cable, it integrates seamlessly with safety controllers and PLCs to prevent accidental machine startup when a guard is open, protecting personnel from hazardous moving parts基恩士. Its compact size (fitting within 30 mm aluminum frames), robust construction, and IP65/67/69K protection rating enable reliable operation in harsh industrial environments with water, oil, high – pressure washdowns, and mechanical impact基恩士. The integrated electromagnetic locking mechanism offers a locking tensile strength of over 2,000 N, ensuring secure guard retention during machine operation基恩士. It is widely used in automotive assembly, packaging machinery, semiconductor fabrication, and other automated processes requiring compliance with global safety standards (ISO 14119, IEC 60947 – 5 – 3), providing a critical safety layer for personnel and equipment.
Main Functions
- Electromagnetic Guard Locking and Unlocking
The electromagnetic locking system keeps the safety guard securely locked during machine operation, with a tensile strength of over 2,000 N to resist forced opening基恩士. It unlocks upon a valid safety signal (e.g., emergency stop activation, system shutdown), and the 320 ms lock – to – unlock response time and 220 ms unlock – to – lock response time ensure quick, safe transitions between machine states基恩士.
- Safety Interlock Monitoring
It provides dual – channel safety outputs (NPN) that send a signal to the safety controller when the guard is closed and locked, enabling machine operation. If the guard is opened while locked, the switch triggers an immediate safety stop, preventing accidental exposure to dangerous machinery.
- Visual Status Indication
Large front – and side – visible indicators (green for normal/locked, red for guard open/unlocked) offer clear status visibility from a distance, simplifying troubleshooting and safety checks in busy industrial settings基恩士.
- Harsh Environment Adaptability
The IP65/67/69K – rated housing resists water, oil, dust, and high – pressure, high – temperature washdowns, making it suitable for food processing, automotive, and chemical manufacturing environments基恩士. It also withstands mechanical shock and vibration, ensuring consistent performance in demanding conditions.
- Flexible Installation and System Integration
The 5 – meter 8 – core loose – wire cable allows flexible connection to safety controllers, and the ±2 mm insertion position tolerance simplifies alignment during installation基恩士. It supports cascade connection with multiple GS – series switches, and its NPN output type integrates easily with common industrial control systems for comprehensive safety interlock setups.
