Safety Switches with Guard Locking from Pilz
March 3, 2026
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.

Protect human and machine with gate guard locking
Are you looking for the right safeguard for your movable guard? Questions regarding the type of safeguard, the required guard locking and the Performance Level are fundamental in selecting the right gate guard 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 gate 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.
