Why Choose the Pizzato NAH220AB-DN1 Limit Switch?
The Pizzato NAH220AB-DN1 is a heavy-duty modular prewired limit switch, engineered for precise position detection and high-reliability safety switching in industrial automation systems. As part of the robust Pizzato NA series, it delivers long service life, strong mechanical durability and consistent switching performance in demanding industrial environments.
This model 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 1 metre PVC cable (DN1), making it ideal for compact installations requiring multiple switching signals.
With its rugged metal housing and multi-contact capability, the NAH220AB-DN1 is particularly suited to complex automation systems where safety, redundancy and reliability are essential.
Key Advantages
- 2 NO + 2 NC contacts for maximum control flexibility and redundancy.
- Positive opening contacts for enhanced safety compliance.
- 1 m prewired cable (DN1) for compact installations.
- Slow-action switching for stable and controlled operation.
- Compact and robust design with plunger actuator.
- Heavy-duty metal housing for industrial durability.
Key Features
