VF PC12A9 Pizzato Coded protective screw covers for the NG series (actuator

Why Choose the Pizzato VF PC12A9 Coded Protective Screw Covers?

The Pizzato VF PC12A9 is a set of coded protective screw covers specifically designed for the actuator of Pizzato NG series safety switches. These tamper-protection accessories snap into the openings of the actuator fixing screws, preventing normal access to the screws once installed and helping protect the actuator against unauthorised removal or adjustment.

Each protective cover carries a unique three-character alphanumeric code. With 32 possible values for each character, an individual cover provides 32,768 possible code combinations. When two coded covers are fitted to the actuator fixing screws, the combined identification provides more than one billion possible combinations, creating a highly distinctive visual record of the installed protection.

The covers can only be removed by breaking them, making interference readily detectable. Recording the installed codes during machine commissioning, for example by photographing them, allows subsequent replacement or tampering to be identified. The VF PC12A9 is supplied in a pack of 10 and can also replace standard screw covers while maintaining tamper-protection functionality.

Key Advantages

• Purpose-designed coded screw covers for Pizzato NG series actuators.
• Snap-on installation prevents normal access to actuator fixing screws.
• Covers must be broken for removal, making tampering evident.
• Individual three-character alphanumeric marking enables installation records to be checked later.
• Two installed covers provide more than one billion possible combined code combinations.
• Supplied in a convenient pack of 10 protective covers.

Key Features

• Pizzato Elettrica tamper-protection accessory.
• Model VF PC12A9.
• Designed specifically for NG series actuators.
• Snap-on fitting into the actuator fixing screw openings.
• Removal requires destruction of the protective cover.
• Each cover carries a three-character coded alphanumeric marking.
• 32,768 possible combinations for each individual cover.
• Laser marking provides durable and resistant code identification.

Coded Tamper Protection for NG Series Actuators

Machine safety devices must be protected against reasonably foreseeable attempts to bypass or alter their intended operation. The VF PC12A9 covers snap over the fixing screws of a compatible NG series actuator, making the screws inaccessible without first destroying the protective covers. This provides a straightforward visual indication when access to the actuator fixing points has occurred.

The individual alphanumeric markings add another layer of traceability. By recording the codes during final machine installation or commissioning, maintenance personnel can later verify whether the original covers remain installed. Because a replacement cover will carry a different code, unauthorised replacement can be identified even when a new protective cover has been fitted.

Typical Applications

• Pizzato NG series safety switch actuator installations.
• Industrial machine guard doors.
• Robotic and automated production cells.
• Packaging and processing machinery.
• Machine safety installations requiring visible tamper evidence.
• Replacement of standard NG actuator screw covers where coded tamper protection is required.
