FS 1896D024-K40 Pizzato FS series safety switch with separate actuator with lock

Why Choose the Pizzato FS1896D024-K40 Safety Interlock Switch?

The Pizzato FS1896D024-K40 is a heavy duty safety switch with separate actuator and guard locking, designed for industrial machinery where controlled access and operator safety are critical. As part of the reliable Pizzato FS series, it ensures that protective guards remain securely locked until safe operating conditions are achieved.

Built with a durable technopolymer housing and a rotating head, this safety switch is engineered for long term performance in demanding industrial environments. Its integrated solenoid locking mechanism prevents access to hazardous zones while machinery is running, helping maintain compliance with modern safety standards.

This model operates on a 24 V AC/DC supply and features a 1 NO + 1 NC contact configuration actuated by the solenoid. It uses the D working method, meaning the actuator remains locked when the solenoid is de-energised, ensuring fail safe operation. The K40 variant includes an M12 8-pole connector interface, enabling quick and reliable electrical connection in automated systems.

Key Advantages

• Guard locking safety switch for controlled access to hazardous machinery.
• M12 8-pole connector simplifies installation and maintenance.
• D working method ensures fail safe locking when power is removed.
• 1 NO + 1 NC contacts for flexible safety circuit integration.
• IP67 protection for resistance to dust and water ingress.
• Durable technopolymer housing for industrial environments.

Advanced Guard Locking for Industrial Safety

Safety interlock switches with guard locking, such as the FS1896D024-K40, are essential where hazardous motion must be fully stopped before access is permitted. The integrated solenoid ensures guards remain locked during operation, reducing the risk of injury.

The D working principle provides fail safe protection by keeping the actuator locked when power is removed. This ensures machinery cannot be accessed until it is safe, even in the event of power failure.

Typical Applications

• Machine guard doors requiring controlled access.
• Packaging and processing machinery.
• Automated production lines and robotics.
• Material handling and conveyor systems.
• Industrial safety interlock systems.
• OEM machinery and automation equipment.
