Why Choose the Pizzato NBB120BB-DN2 Modular Pre-Wired Position Switch?
The Pizzato NBB120BB-DN2, manufacturer designation NB B120BB-DN2, is a robust modular pre-wired position switch with roller plunger designed for reliable detection of machine position, movement and mechanical end-of-travel conditions. As part of the versatile Pizzato NB series, it combines a compact metal housing, snap-action switching and factory-fitted cable for efficient integration into industrial machinery and automation systems.
The roller plunger actuator provides smooth mechanical engagement with moving cams, slides and machine components, reducing friction during repeated operation. The B12 snap-action contact block provides 1 normally open (NO) + 2 normally closed (NC) contacts, giving control systems multiple switching signals for monitoring, interlocking and machine sequencing.
The NBB120BB-DN2 is supplied pre-wired with a 2 m, 7-core PVC cable with 0.5 mm² conductors. Its NB series metal housing uses 25 mm mounting-hole spacing and provides high environmental protection up to IP67 and IP69K, making it suitable for demanding industrial applications exposed to dust, moisture and frequent mechanical operation.

Reliable Position Detection for Industrial Machinery
Electromechanical position switches provide industrial control systems with reliable feedback when a moving machine component reaches a predetermined position. On the NBB120BB-DN2, movement against the roller plunger operates the internal snap-action mechanism, changing the state of the contacts so that a PLC, relay or other control device can respond immediately.
The Pizzato NB series is designed around modularity, robust construction and efficient installation. The roller plunger of the NBB120BB-DN2 is particularly suitable for direct linear actuation by cams and moving machine components, while its pre-wired construction and multiple contacts make it a practical choice for machine monitoring, interlocking and automated sequencing.
Typical Applications
- Industrial machinery position detection.
- Machine end-of-travel monitoring.
- Conveyor and material handling systems.
- Packaging and production machinery.
- Automated assembly and manufacturing equipment.
- Mechanical interlocking and sequencing systems.
