Why Choose the Pizzato NAG220AB-DN2W5 Limit Switch?
The Pizzato NAG220AB-DN2W5 is a heavy-duty modular prewired limit switch, engineered for precise position detection and advanced safety switching in industrial automation systems. As part of the robust Pizzato NA series, it delivers long service life, high mechanical strength and consistent performance in demanding environments.
This version features a 2 NO + 2 NC slow-action contact configuration with positive opening, providing maximum redundancy for safety-critical applications. It is equipped with a plunger actuator and a 2 metre PVC cable with W5 configuration, enabling flexible installation and optimised cable routing for complex machinery layouts.
With its rugged metal housing and multi-contact design, the NAG220AB-DN2W5 is particularly suited to industrial systems requiring high reliability, redundant safety circuits and multiple switching outputs.
Key Advantages
- 2 NO + 2 NC contacts for maximum control flexibility and redundancy.
- Positive opening contacts for safe disconnection under fault conditions.
- DN2W5 prewired cable for flexible installation and routing.
- Slow-action switching for stable and controlled performance.
- Compact design with plunger actuator.
- Heavy-duty metal housing for industrial durability.
Key Features

Advanced Safety with 2NO + 2NC Configuration
The NAG220AB-DN2W5 provides four independent contacts, enabling advanced safety logic, redundancy and multi-channel monitoring. This makes it ideal for applications requiring dual-channel safety circuits or higher safety integrity levels.
Combined with positive opening technology, the switch ensures reliable mechanical separation of contacts even in the event of welding or internal failure, improving machine safety and operational reliability.
Typical Applications
- Machine guarding and safety interlock systems.
- Industrial conveyors and material handling equipment.
- Packaging and automated production lines.
- High-risk machinery requiring redundant contacts.
- OEM automation systems and control panels.
- Applications requiring multiple switching outputs and flexible cable routing.
