Pilz safety switches with guard locking provide secure interlocking and reliable guard locking for movable gates, covers, and flaps. Designed for applications up to PL e / SIL 3, they prevent access until hazardous movements stop and ensure productive, tamper-resistant machine operation.
Pilz safety switches with guard locking are engineered to provide robust protection for machines that use movable guards such as sliding gates, swing gates, covers, and access flaps. When hazardous overrun movements may occur, these devices ensure that the gate cannot be opened until dangerous motion has fully stopped, and the machine cannot restart until the guard is safely closed and locked. With integrated manipulation protection according to EN ISO 14119, they prevent users from defeating or bypassing the safety function.
Offering a wide and flexible portfolio, Pilz guard locking switches are suitable for both personnel and process protection and support safety levels up to PL e (EN ISO 13849) or SIL 3 (EN IEC 62061). Their modular design enables quick installation and cost-efficient wiring, including the option for safe series connection with diagnostic support. Freely selectable coding levels enhance manipulation resistance, helping minimise unwanted production interruptions.
For a complete safety gate solution, Pilz combines these switches with complementary components such as the PITgatebox pushbutton unit—with optional integrated access management—control units, wiring systems, and the configurable safe small controller PNOZmulti 2. Additional accessories like escape releases and compatible handles ensure a fully customised and reliable safety gate system. With comprehensive diagnostics via Safety Device Diagnostics (SDD), operators benefit from improved visibility into system status, high availability, and extended service life.
