FY 61MD1E0A Pizzato FY series safety switch with separate actuator with lock

Why Choose the Pizzato FY 61MD1E0A Safety Switch?

The Pizzato FY 61MD1E0A is a robust safety switch with separate actuator and guard locking designed for monitoring and securing movable guards on industrial machinery. As part of the Pizzato FY series, it combines mechanical guard interlocking with solenoid-controlled locking for 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 operating principle is suitable for machine safety systems where energised guard locking is required and release following removal of solenoid power is appropriate for the application.

The FY 61MD1E0A incorporates the 61M slow-action contact block, providing 3NO contacts operated by the actuator and 1NC contact operated by the solenoid. Its FY series locking mechanism provides a maximum actuator holding force of 2,800 N, while the robust technopolymer housing and metal head make it suitable for demanding industrial automation and machine safety installations.

Key Advantages

• Industrial safety switch with separate actuator and guard locking.

Energised Guard Locking for Industrial Machinery

Guard locking switches such as the Pizzato FY series combine separate-actuator guard detection with a mechanical locking mechanism, allowing machinery designers to control access to hazardous areas as part of the overall safety system. The separate actuator is mounted to the movable guard and engages with the switch head when the guard reaches its closed position.

With operating principle E, the FY 61MD1E0A retains the actuator while its solenoid is energised and releases the actuator when solenoid power is removed. Its 61M slow-action contact arrangement provides three actuator-operated contacts together with a solenoid-operated NC contact, enabling guard position and locking status information to be incorporated into the machine control and safety architecture.

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.
