Why Choose the Pizzato NBB220HH-DN2W5 Limit Switch?
The Pizzato NBB220HH-DN2W5 is a heavy-duty modular prewired limit switch engineered for precise and reliable position detection in demanding industrial automation environments. As part of the robust Pizzato NB series, this model features a spring rod actuator with flexible “cat’s whisker” tip and 90° transmission block, enabling highly sensitive detection of irregular or low-force contact points.
Constructed with a rugged metal housing, the switch is designed to withstand harsh industrial conditions including vibration, dust and washdown environments. Its prewired PVC cable (5 metres) significantly reduces installation time and simplifies wiring across machinery and control systems.
With a 2NO + 2NC snap-action contact configuration, the NBB220HH-DN2W5 provides multiple switching outputs and redundancy, making it ideal for complex control systems and safety-critical applications.
