FY 61SD1E0A Pizzato FY series safety switch with separate actuator with lock

Why Choose the Pizzato FY 61SD1E0A Safety Switch?

The Pizzato FY 61SD1E0A is a robust safety switch with separate actuator and guard locking designed for securing movable guards on industrial machinery. As part of the Pizzato FY series, it combines separate-actuator guard detection with solenoid-controlled locking for industrial applications requiring controlled access to hazardous machine areas.

This safety switch uses operating principle E, meaning the actuator is locked when the solenoid is energised and released when power to the solenoid is removed. This configuration is suitable for safety systems where energised guard locking is appropriate and where the risk assessment permits release of the guard following loss of solenoid power.

The FY 61SD1E0A incorporates the 61S slow-action contact block, providing 3NO+1NC contacts operated by the solenoid. It operates from a 24 V AC/DC solenoid supply and features two green LEDs, a durable glass-fibre reinforced technopolymer housing and a metal operating head for reliable service in demanding industrial environments.

Key Advantages

• Industrial safety switch with separate actuator and guard locking.
• Actuator locked with the solenoid energised for operating principle E applications.
• 2,800 N maximum actuator holding force for secure machine guard retention.
• 3NO+1NC solenoid-operated contacts for monitoring the locking mechanism.
• 24 V AC/DC solenoid supply for integration with common industrial control systems.
• Two green LEDs provide visual status indication.
• High environmental protection with IP67 and IP69K ratings.

Key Features

• Pizzato FY series safety switch with separate actuator and locking function.
• Operating principle E with actuator locked by an energised solenoid.
• 61S slow-action contact block.
• 3NO+1NC contacts operated by the solenoid.
• 24 V AC/DC solenoid power supply.
• Two green signalling LEDs.
• Glass-fibre reinforced, self-extinguishing and shock-resistant technopolymer housing.
• Powder-coated metal operating head and release device.
• Three M20 × 1.5 threaded conduit entries.
• Separate actuator design allows a compatible FY series actuator to be selected for the application.

Energised Guard Locking for Industrial Machinery

Guard locking switches such as the Pizzato FY series combine a separate actuator with a mechanical locking mechanism to control access to guarded areas. The actuator is mounted on the movable guard and enters the switch head when the guard closes, allowing the locking mechanism and associated contacts to form part of the machine safety and control architecture.

With operating principle E, the FY 61SD1E0A retains the actuator while its solenoid is energised and releases the actuator when solenoid power is removed. Its 61S contact block provides four solenoid-operated contacts, making the switch particularly suited to applications requiring multiple electrical signals associated with the locking mechanism.

Typical Applications

• Machine guard doors and access gates.
• Industrial robots and automated production cells.
• Packaging and processing machinery.
• Conveyors and material handling systems.
• Machining centres and manufacturing equipment.
• Industrial machinery requiring energised-solenoid guard locking.
