Why Choose the Pizzato FR2131-W3M2 Safety Limit Switch?
The Pizzato FR2131-W3M2 is a heavy-duty safety limit switch with manual reset, engineered for precise position detection and controlled restart in industrial automation systems. As part of the reliable Pizzato FR series, it is designed for safety-critical applications where preventing automatic restart is essential.
This model features a roller lever actuator, ensuring smooth and repeatable actuation when interacting with moving machine components. It is equipped with three normally closed (3 NC) contacts with positive opening operation, providing high redundancy and safe circuit interruption even under fault conditions.
The integrated manual reset (simultaneous reset) mechanism ensures that the switch must be deliberately reset after activation, preventing unintended machine restart. With a durable technopolymer housing and M20 x 1.5 conduit entry, the FR2131-W3M2 offers excellent resistance to mechanical stress, dust and moisture in harsh industrial environments.
