SMC NIS1000E-3N03Y-X20 Pneumatic Pressure Switch

The SMC NIS1000E-3N03Y-X20 Pneumatic Pressure Switch is a compact device in SMC's NIS1000E family that converts pneumatic pressure into an electrical switch signal when the preset pressure is reached. The model code confirms a 3/8 in NPT port connection, a common size for industrial pneumatic lines, and the -X20 suffix identifies a specific body variant within the NIS1000E lineup. A closely related configuration, NIS1000E-3N03YT-X201, is described as having a fixed SI unit display and bracket mounting, with the body ported, which demonstrates some of the mounting and display options available across this family. In typical use, pressure switches in this series monitor pneumatic pressure in control loops and provide a discrete switch output to drive valves, actuators, or logic controllers when the set pressure is reached. Because exact electrical characteristics (such as contact configuration and load rating) can vary by variant, confirm the NIS1000E-3N03Y-X20 documentation or retailer listing for your application to verify the switch type and electrical compatibility before integration.
