Why Choose the Pizzato NAB120AC-DN2 Limit Switch?
The Pizzato NAB120AC-DN2 is a high-reliability modular prewired limit switch designed for precise position detection and enhanced safety switching in industrial automation systems. As part of the robust Pizzato NA series, it provides durable construction, long service life and consistent performance in demanding environments.
This model features a 1 NO + 2 NC snap-action contact configuration with positive opening, offering increased redundancy for safety-critical circuits. It includes a long plunger actuator (AC variant) and a 2 metre PVC cable (DN2), providing extended actuation tolerance and flexible installation.
With its rugged metal housing and integrated cable, the NAB120AC-DN2 is ideal for machine builders and engineers requiring reliable safety monitoring and straightforward wiring.
Key Features
- Pizzato NA series modular prewired limit switch.
- 1 NO + 2 NC snap-action contacts (B12 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 / IP69K protection rating for harsh environments.
- 20 mm fixing centres for standard mounting.
Enhanced Safety with 1NO + 2NC Configuration
The 1 NO + 2 NC configuration provides increased redundancy for safety circuits. The dual normally closed contacts enable continuous monitoring of circuit integrity, while the normally open contact supports signalling or control functions.
Combined with positive opening technology, the switch ensures reliable mechanical separation of contacts even in the event of contact welding, improving overall machine safety.
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.
