Why Choose the Pizzato NAB220AB-DN5 Limit Switch?
The Pizzato NAB220AB-DN5 is a heavy-duty modular prewired limit switch, designed for precise position detection and high-reliability safety switching in industrial automation systems. As part of the robust Pizzato NA series, it offers durable construction, flexible installation and consistent performance in demanding industrial environments.
This model features a 2 NO + 2 NC snap-action contact configuration with positive opening, providing maximum redundancy for safety-critical circuits. It is equipped with a plunger actuator and a 5 metre PVC cable (DN5), making it ideal for extended installations without the need for additional junction boxes.
With its rugged metal housing and multi-contact capability, the NAB220AB-DN5 is particularly suited to complex automation systems requiring advanced safety monitoring and multiple control signals.
Key Advantages
- 2 NO + 2 NC contacts for maximum control flexibility and redundancy.
- Positive opening contacts for enhanced safety compliance.
- 5 m prewired cable (DN5) for extended installation reach.
- Snap-action switching for fast and reliable operation.
- Compact, robust design with plunger actuator.
- Heavy-duty metal housing for industrial durability.
Key Features
- Pizzato NA series modular prewired limit switch.
- 2 NO + 2 NC snap-action contacts (B22 configuration).
- Positive opening operation for safety circuits.
- Plunger actuator for direct mechanical actuation.
- PVC cable (5 m length) compliant with IEC 60332-1.
- Metal housing with high resistance to impact and wear.
- IP67 / IP69K protection rating for harsh environments.
- 20 mm fixing centres for standard mounting.
Advanced Safety with 2NO + 2NC Configuration
The NAB220AB-DN5 provides four independent contacts, enabling complex safety logic and redundant monitoring in critical applications. This makes it suitable for systems requiring dual-channel safety or higher safety integrity levels.
Combined with positive opening technology, it ensures reliable disconnection even in the event of contact welding, significantly improving machine safety and operational reliability.
