At the Hannover Messe - Safety switches with guard locking
Safety switches with guard locking
Work safely and productively - with safety switches from Pilz
Movable guards such as swing gates and sliding gates, flaps or covers, can be found in almost every application. If there are dangerous overrun movements, a safety locking device with appropriate manipulation protection in accordance with EN ISO 14119 is required.
The safety gate cannot be opened until all hazardous machine movements are stopped. A restart is not possible until the safety gate is closed and locked. It must not be possible to either defeat or manipulate the safeguards.
Pilz safety switches with guard locking offer the right solution for both process and personnel protection - for safe, productive working.
Safe guard locking. Efficient production.
- Comprehensive portfolio of switches offers a high level of flexibility during the machine design
- Designed for all applications up to PL e of EN ISO 13849 or SIL 3 of EN IEC 62061
- Saves time and costs thanks to simple installation and the option for safe series connection with diagnostics
- Protection against hazardous machine movements due to monitoring of safe interlocking and safe guard locking
- High level of safety and productivity: manipulation protection prevents unwanted production interruptions; coding freely selectable
- Individual safety gate solution tailored to the application
- High availability and long service life of the sensors
Get the information you need at the Hannover Messe!
Discover everything you need to know about the new safety locking devices at the Hannover Messe. Of course we will also be showcasing the two new sensors: The new PSENmlock mini for space-critical applications, such as flaps or covers, and the new generation PSENslock 2 with a new design for robust applications.
Why not arrange a consultation with our experts directly at the exhibition to discuss your specific project.
Protect human and machine
Are you looking for the right safeguard for your movable guard? The question regarding the type of safeguard, the required locking device and the performance level are the basis for selecting the right safety locking device:
Type of safeguard
Is it an accessible or a non-accessible safeguard? Accessible safeguards are generally larger swing and sliding gates; non-accessible safeguards are covers or flaps, for example.
Process guarding or safe guard locking
The question regarding the type of guard locking depends on the stopping time. If the time to reach the danger zone is longer than the stopping time, process guarding is sufficient. If the intervention time is shorter than the stopping time, however, safe guard locking (personnel protection) is required.
Performance Level
The level of protection is defined in accordance with EN ISO 13849-1 or EN 62061. The key factors for this calculation, for example, are the severity of the potential injuries, frequency of exposure to the risk and ability to avoid the risks.
