£32.46
The Pizzato FP 21R2-L05M2 is a robust safety switch with manual mechanical delay and separate actuator designed for guarding industrial machinery, access doors and protective enclosures. As part of the Pizzato FP safety switch series, it combines positive machine guarding with a manually operated mechanical delay that helps prevent access to hazardous areas before machinery has reached a safe condition.
This safety switch uses a durable technopolymer housing and a 3NC slow-action contact block for dependable safety circuit monitoring. The manual mechanical delay mechanism incorporates a long operating knob with an approximately 5 s delay, providing a simple mechanical means of delaying guard release without requiring an electrically powered locking system.
With IP67 protection and a threaded M20 × 1.5 cable entry, the FP 21R2-L05M2 is suitable for demanding industrial environments where machinery guards and access points require reliable position monitoring. Its separate-actuator design makes it particularly suitable for hinged, sliding and removable machine guards.
Safety switches with separate actuators are commonly fitted to movable machine guards so that opening the guard changes the state of the safety contacts. This allows the machine safety control system to detect guard movement and stop or inhibit hazardous machine operation where required.
The FP 21R2-L05M2 adds a manually operated mechanical delay to this guarding principle. The approximately 5 s delay provides additional time before guard release, making the switch suitable for machinery where hazardous movement may continue briefly after a stop command. Its mechanical operating principle also allows the delay function to work without requiring a powered solenoid locking mechanism.
