FY 61MD6D0A Pizzato FY series safety switch with separate actuator with lock

Why Choose the Pizzato FY 61MD6D0A Safety Switch?

The Pizzato FY 61MD6D0A is a robust FY series safety switch with separate actuator and solenoid guard locking, designed for monitoring and locking movable guards on industrial machinery. Its technopolymer housing, monitored locking system and four-contact configuration make it suitable for machinery where access must remain restricted until hazardous movement or operating conditions have ceased.

This version uses operating principle D, meaning the actuator remains locked when the solenoid is de-energised. The switch incorporates 1NC contact operated by the actuator and 3NO contacts operated by the solenoid, providing electrical monitoring of guard position and locking status. A 24 V AC/DC solenoid supply and two green status LEDs support straightforward integration into industrial machine safety systems.

The FY 61MD6D0A features an orientable head incorporating both a key-operated auxiliary release and anti-panic escape release pushbutton. The locking mechanism provides a maximum holding force of 2800 N, while the technopolymer enclosure provides IP67 and IP69K protection and incorporates three M20 × 1.5 threaded cable entries. The actuator is selected separately, allowing a compatible Pizzato actuator to be matched to the machine guard arrangement.

Key Advantages

• Industrial safety switch with separate actuator and solenoid guard locking.
• Operating principle D keeps the actuator locked when the solenoid is de-energised.

Fail-Safe Guard Locking for Industrial Machinery

Safety switches with separate actuators and solenoid locking are used on machine doors, gates and protective covers where opening a guard while hazardous conditions remain could expose personnel to risk. When a compatible actuator enters the FY 61MD6D0A switch head, the safety system can monitor the position of the guard and the state of the locking mechanism.

The FY 61MD6D0A uses a de-energise-to-lock operating principle, helping maintain mechanical guard locking if power to the solenoid is removed. Its key-operated auxiliary release provides controlled manual unlocking when required, while the anti-panic escape release allows the locking mechanism to be released from within a protected area when correctly incorporated into the machine safety design.

Typical Applications

• Industrial machine guards and interlocked access doors.
• Automated production and assembly machinery.
• Packaging and processing equipment.
• Robotic cells and automated manufacturing systems.
• Machinery with hazardous residual movement or run-down time.
• Guarded areas requiring auxiliary and anti-panic release functionality.
