Why Choose the Pizzato NAG220AB-DN2 Limit Switch?
The Pizzato NAG220AB-DN2 is a high-performance modular prewired limit switch, designed for precise position detection and advanced safety switching in industrial automation systems. As part of the robust Pizzato NA series, it offers excellent durability, modular flexibility and consistent switching performance in demanding 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 2 metre PVC cable (DN2), making it ideal for installations requiring multiple signal outputs and reliable long-term operation.
With its rugged housing and multi-contact design, the NAG220AB-DN2 is particularly suited to complex control 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.
- 2 m prewired cable (DN2) for practical installation.
- Slow-action switching for stable and controlled operation.
- Compact, robust design with plunger actuator.
- Durable housing for industrial environments.
