Why Choose the Pizzato NAB110AC-DMK Limit Switch?
The Pizzato NAB110AC-DMK is a robust modular limit switch designed for precise position detection and reliable switching in industrial automation systems. Part of the proven Pizzato NA series, it offers long mechanical life, durable construction and dependable operation in demanding environments.
This model features a 1 NO + 1 NC snap-action contact configuration with positive opening, ensuring safe disconnection in safety-related circuits. It is equipped with a long plunger actuator (AC variant) and an M12 connector interface (DMK), providing both extended actuation tolerance and fast, modular installation.
With its rugged metal housing and connector-based wiring, the NAB110AC-DMK is ideal for applications requiring both mechanical flexibility and efficient maintenance.
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 increased actuation travel.
- M12 connector (DMK) for fast plug-and-play installation.
- Metal housing with high resistance to wear and impact.
- IP67 protection rating for industrial environments.
- 20 mm fixing centres for standard mounting.
Extended Actuation with Long Plunger
The AC long plunger design provides increased actuation travel, making the switch more tolerant to mechanical misalignment and variation. This improves reliability in real-world installations where precise positioning cannot always be guaranteed.
Combined with snap-action switching and positive opening contacts, the switch ensures fast response and safe operation even under fault conditions.
Typical Applications
- Machine guarding and safety interlock systems.
- Industrial conveyors and material handling equipment.
- Packaging and automated production lines.
- Applications requiring extended actuation travel.
- OEM automation systems using M12 connectivity.
