Sensors & Switches
Industrial sensors and switches, sometimes referred to as transducers, installed in the factory automation space can provide essential machine feedback. They can monitor On/Off status, confirm operation within an optimal range, or measure real time operation e.g. pressure or flow.
Industrial sensors and switches can connect to a PLC or other central controller via fieldbus or IO link to enhance troubleshooting by decreasing diagnostic time. Sensors can also become the data source for providing better predictive analytics integral to Industrial Internet of Things (IIoT) or Industry 4.0, all while potentially increasing worker safety.
SMC’s pressure sensors (ISE/ZSE) will provide a setpoint-trip signal if a minimum or maximum pressure threshold is broken. The ITV Series electro-pneumatic (E/P) regulator will control air/vacuum pressure steplessly in proportion to an electric signal. PF Series flow sensors will monitor flow rate of air, cooling or cleaning water.

Within the collection you will find IP ratings as high as IP67, IO-Link capability, and pneumatic or liquid compatibility. Multi-line, multi-color displays offer more information with better visibility. Digital and analog outputs characterize operational conditions in useful ways. Categories are clearly defined to assist product selection.
Vacuum/Compound Pressure Sensors
SMC offers a range of vacuum monitoring devices to meet the diverse application requirements of our customer base. Within the collection you will find IP ratings as high as IP67, IO-Link capability, and pneumatic or liquid compatibility. Multi-line, multi-color displays offer more information with better visibility. Digital and analog outputs characterize operational conditions in useful ways. Categories are clearly defined to assist product selection.
Air Flow Sensors
Air flow sensors provide instantaneous flow information for the compressed air supply of your applications. Sensors may have integrated displays, or remote units with separate ouput monitors. Displays may be mult-line and multi-color, offering more information with better visibility. Digital and analog outputs characterize operational conditions in useful ways. Features include multiple flow ranges, enclosure ratings up to IP65, and IO-Link capability.
Air Management System
The Air Management System automatically regulates and isolates the compressed air provided to a machine to improve efficiencies during periods of inactivity. The unit generates pressure, flow, and temperature data to characterize normal operating conditions and identify trends to both compare with similar machines and enable preventative action to maintain optimal system performance. The unit does not require reprogramming of the user's PLC to operate, making integration both simple and cost effective. The high-resolution data is accessed by the PLC via fieldbus and SCADA packages via OPC UA. Using OPC UA and wireless systems, the Air Management System can be added without connector to the PLC or changes to PLC programming.
Liquid Flow Devices
Liquid flow devices include instantaneous flow sensors, mechanical flow switches giving an ouput signal at a set point, and a flow controller for supply stability. Sensors within the collection are optimized for a variety of conditions, including compatibility with water, coolant, or chemicals; detection method; space constraints; and manifold configuration. Outputs range from simle ON/OFF confirmation signals, mA or V analog, or digital IO-Link. Review the categories to select a product best suited for your application.
SMC offers a variety of auto switches for actuators and air grippers. Reed and solid state switches are available in a general purpose type or with 2-color indication, which allows the optimum operating position to be determined by the color of the light. Solid state switches are also available in 2-color indication with diagnostic output, water resistant 2-color indication, built-in OFF-delay timer (200 ms), magnetic field resistant, heat resistant and wide range detection configurations. Various lead wire lengths are available.
Electro pneumatic air regulators control air/vacuum pressure steplessly in proportion to an electric signal. They are light weight in design with a bright and easy to read LED display. The monitor output is available either as analog output or switch output.
