FR 1193-E3M2 Pizzato Safety switch with separate actuator

Why Choose the Pizzato FR 1193-E3M2 Safety Switch?

The Pizzato FR 1193-E3M2 is an industrial safety switch with separate actuator designed for monitoring movable machine guards, doors and access points. Part of the Pizzato FR series, it uses a separate actuator arrangement so that opening the protected guard withdraws the actuator from the switch head and changes the state of the safety contacts.

This configuration incorporates a B11 snap-action contact block with 2 NC contacts and positive-opening operation for dependable interruption of safety circuits. The E3 version provides an increased actuator extraction force of approximately 30 N, helping the guard remain securely engaged against vibration or unintended movement while still allowing normal opening when required.

The FR 1193-E3M2 uses a durable technopolymer housing with one M20 × 1.5 threaded cable entry. With protection ratings of IP67 according to EN 60529 and IP69K according to ISO 20653, it provides a robust solution for machine-safety applications in demanding industrial environments.

Reliable Guard Monitoring for Industrial Machine Safety

Separate-actuator safety switches are used to monitor the position of movable guards protecting hazardous machinery. With the Pizzato FR 1193-E3M2, the actuator enters the switch head when the guard is closed. Opening the guard withdraws the actuator and operates the 2 NC positive-opening safety contacts, allowing a correctly designed safety control system to initiate the required machine stop function.

The E3 increased extraction-force configuration is particularly useful where vibration, guard movement or mechanical conditions could otherwise cause unwanted actuator withdrawal. Combined with the robust FR-series technopolymer housing and high environmental protection ratings, this makes the FR 1193-E3M2 suitable for dependable guard-position monitoring across a wide range of industrial machinery.

Typical Applications

• Industrial machine guard monitoring.
• Safety doors and access gates.
• Automated production and assembly machinery.
• Packaging and processing equipment.
• Conveyor safety systems.
• Robotic cells and automated manufacturing equipment.
• Machine-tool guarding.
• Applications requiring increased resistance to unintended actuator extraction.
