Why Choose the Pizzato NAB110AC-SMK Limit Switch?

The Pizzato NAB110AC-SMK is a rugged modular limit switch with connector interface, designed for precise position detection and reliable safety switching in industrial automation systems. As part of the proven Pizzato NA series, it offers durable metal construction, long mechanical life and dependable performance in demanding environments.

This model features a 1 NO + 1 NC snap-action contact configuration with positive opening, ensuring safe disconnection in safety circuits. It includes a long plunger actuator (AC variant) and an M12 5-pin connector (SMK), enabling fast, secure and modular wiring without fixed cables.

With its compact design and connector-based interface, the NAB110AC-SMK is ideal for machinery requiring quick installation, easy replacement and reduced downtime.

Key Features

  • Pizzato NA series modular limit switch.
  • 1 NO + 1 NC snap-action contacts (B11 configuration).
  • Positive opening operation for safety circuits.
  • Long plunger actuator (AC) for extended actuation travel.
  • M12 5-pin connector (SMK) for plug-and-play wiring.
  • Metal housing with high resistance to impact and wear.
  • IP67 protection rating for industrial environments.
