Why Choose the Pizzato FP33R2-L20 Safety Switch?
The Pizzato FP33R2-L20 is a heavy-duty safety switch with manual mechanical delay, designed to ensure controlled machine stopping and safe operator access in industrial automation systems. As part of the robust Pizzato FP33R2 series, it delivers high reliability, strong actuator retention and long service life in demanding industrial environments.
This model features a manual mechanical delay of approximately 20 seconds, ensuring that safety contacts remain engaged after actuation. This extended delay allows hazardous machine motion to fully stop before access is permitted, significantly improving operator safety and helping ensure compliance with machinery safety standards.
Designed for use with a separate actuator, the FP33R2-L20 enables flexible installation across machine guards, safety doors and access points. Its rugged construction and dependable switching behaviour make it ideal for safety-critical industrial applications requiring controlled access.
Key Advantages
- Manual mechanical delay (approx. 20 s) ensures safe machine run-down.
- Flexible installation with separate actuator systems.
- Positive opening NC contacts for safety-critical circuits.
- High actuator locking force for secure guard retention.
- Reliable performance in machine guarding and interlock systems.
- High durability for harsh industrial environments.
Key Features
- Pizzato FP33R2 series safety switch.
- Model: FP33R2-L20
- Function: Manual mechanical delay (approx. 20 s).
- Actuation: Separate actuator required.
- Contact configuration: Typically 1 NO + 2 NC.
- Positive opening NC contacts.
- Key-operated safety mechanism.
- Heavy-duty industrial construction.
Controlled Access and Enhanced Machine Safety
The FP33R2-L20 is designed for machinery where immediate access could present a hazard. Its extended delay mechanism ensures that moving parts have fully stopped before unlocking or disengagement occurs, significantly improving operator safety.
With a longer delay compared to L10 variants, it is particularly suited to high-inertia machinery and applications requiring extended stopping times, ensuring full risk mitigation before access is allowed.
Typical Applications
- Machine guarding and safety interlock systems.
- Industrial automation with extended stopping times.
- Conveyor systems and heavy machinery.
- Packaging and processing equipment.
- Safety doors and access panels.
- Hazardous motion zones requiring controlled shutdown.
