Keyence GS – 71N5 Safety Interlock Switch
Product Overview
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.
