Why Choose the Pizzato NAB020AC-DN2 Limit Switch?
The Pizzato NAB020AC-DN2 is a compact and durable modular prewired limit switch, engineered for reliable position detection and safety switching in industrial automation systems. As part of the proven Pizzato NA series, it offers long service life, robust metal construction and dependable performance in demanding environments.
This model features a 2 NC snap-action contact configuration with positive opening, making it ideal for fail-safe safety circuits. It is equipped with a long plunger actuator (AC variant) and a 2 metre PVC cable (DN2), providing both extended actuation tolerance and flexible installation.
With its rugged housing and integrated cable, the NAB020AC-DN2 is well suited for applications requiring reliable safety monitoring and straightforward installation without connectors.
Key Features
- Pizzato NA series modular prewired limit switch.
- 2 NC snap-action contacts (B02 configuration).
- Positive opening operation for safety circuits.
- Long plunger actuator (AC) for extended actuation travel.
- 2 m PVC cable (DN2) for flexible installation.
- Metal housing with high resistance to wear and impact.
- IP67 protection rating for industrial environments.
- 20 mm fixing centres for standard mounting.
Extended Actuation with Long Plunger
The AC long plunger design provides increased actuation travel, improving tolerance to mechanical misalignment and variation. This enhances reliability in real-world installations where precise positioning cannot always be guaranteed.
Combined with snap-action switching and positive opening contacts, the switch ensures rapid response and safe disconnection even under fault conditions such as contact welding.
Typical Applications
- Machine guarding and safety interlock systems.
- Industrial conveyors and material handling equipment.
- Packaging and automated production lines.
- Applications requiring extended actuation travel.
- OEM automation systems with fixed cable installations.
