Why Choose the Pizzato NAL120AB-DN2 Limit Switch?
The Pizzato NAL120AB-DN2 is a robust modular prewired limit switch, engineered for precise position detection and enhanced safety switching in industrial automation systems. As part of the reliable Pizzato NA series, it delivers consistent performance, long mechanical life and high resistance to harsh industrial conditions.
This model features a 1 NO + 2 NC slow-action contact configuration with positive opening, providing increased redundancy for safety-critical circuits. It is equipped with a plunger actuator and a 2 metre PVC cable (DN2), offering a practical balance between installation flexibility and simplified wiring.
With its durable metal housing and expanded contact configuration, the NAL120AB-DN2 is particularly suited to safety systems and industrial control applications where reliability and redundancy are essential.
Key Advantages
- 1 NO + 2 NC contacts for enhanced safety redundancy.
- Positive opening contacts for reliable fault disconnection.
- 2 m prewired cable (DN2) for flexible installation.
- Slow-action switching for stable and controlled operation.
- Compact form factor with plunger actuator.
- Heavy-duty metal housing for industrial durability.

Enhanced Safety with 1NO + 2NC Configuration
The NAL120AB-DN2 is designed for applications requiring redundant safety monitoring. The two normally closed contacts allow continuous circuit supervision, while the additional normally open contact provides flexible control or signalling functions.
Combined with positive opening technology, the switch ensures reliable disconnection even in the event of contact welding or mechanical failure, improving overall system safety and compliance with industrial standards.
Typical Applications
- Machine guarding and safety interlock systems.
- Industrial conveyors and material handling equipment.
- Packaging and automated production lines.
- Safety monitoring in industrial machinery.
- OEM automation systems requiring redundant contacts.
- General industrial position detection.
