The SMC ITV2090-31F2N5 is an electronic vacuum regulator designed for applications that need stable, proportional vacuum control through an electrical signal. It belongs to SMC’s ITV2090/2091 series, which is intended for stepless vacuum regulation in automated systems. In the official series specification, SMC states that the ITV2090 range provides a regulating pressure range of -1.3 to -80 kPa, supports 0 to 50°C ambient and fluid temperature, offers IP65 equivalent protection, and has a unit weight of 350 g for this size class.
From the model code structure published in the SMC catalog, the suffix for ITV2090-31F2N5 indicates a 0 to 10 VDC input signal, 1 to 5 VDC analog monitor output, G thread specification, 1/4 port size, and a 5 kPa display unit selection. The same catalog also shows that the N option corresponds to without cable connector. RS Singapore separately lists this exact model as an SMC 1/4 in G port vacuum regulator in the ITV2090 series.

Product Function and Working Role
The SMC ITV2090-31F2N5 is engineered to control vacuum pressure continuously in proportion to an electric signal. This is one of the defining functions of the ITV2090 family. Instead of adjusting vacuum manually or using fixed-step regulation, the regulator changes vacuum level dynamically according to the input command. That makes it well suited for production equipment where vacuum force has to match different workpieces, materials, or process requirements.
In practical machine design, this means the regulator can help stabilize suction performance in handling, transfer, gripping, and positioning processes. A packaging machine, electronic assembly station, or robotic pick-and-place system may process parts with different surface conditions or weights. In such cases, proportional vacuum control improves consistency because the vacuum level can be tuned from the control system instead of through repeated manual adjustment. This family also provides monitor output options, and in this exact configuration the output is 1 to 5 VDC analog, which is useful for machine-side monitoring and control feedback.
Why the ITV2090-31F2N5 Is Useful in Automation
A major advantage of this model is its compatibility with standard industrial control architectures. The 0 to 10 VDC input signal is widely used in PLC and controller environments, making the regulator straightforward to integrate into new equipment or retrofit projects. The 1 to 5 VDC analog monitor output provides a way to observe regulator behavior from the machine side, which is valuable in systems that require process verification or diagnostics.
Another important benefit is environmental durability. The official SMC specification lists the ITV2090 series as IP65 equivalent, which supports use in typical factory conditions where dust and incidental water exposure can be present. The operating temperature range of 0 to 50°C also matches many industrial automation environments, including packaging lines, assembly stations, feeder systems, and material handling equipment.
The relatively low product weight is also relevant. At approximately 350 g, the ITV2090 is light enough for compact machine layouts and modular installations. This matters in modern equipment where designers often want to reduce panel congestion, shorten pneumatic paths, and keep assemblies manageable for service work. A compact regulator with low mass can be easier to mount close to the point of use, which may simplify piping layout and improve overall machine organization.
Performance Characteristics
The ITV2090 series is not just a convenience component; it is a control component with measurable performance characteristics. In the official SMC data, the family is specified with linearity within ±1% full span, hysteresis within 0.5% full span, repeatability within ±0.5% full span, and sensitivity within 0.2% full span. These figures indicate that the regulator is intended for applications where stable and repeatable vacuum control is important rather than optional.
The same series specification lists temperature characteristics within ±0.12% full span per °C and display accuracy of ±3% full span. These values are useful when selecting a vacuum regulator for processes that need better predictability over time. For machine builders, this means the regulator is suitable for systems where process windows are relatively tight and the vacuum setting cannot drift excessively without affecting production results.

Application Areas
The SMC ITV2090-31F2N5 is suitable for a wide range of automated systems that rely on controllable vacuum rather than simple on/off suction. Typical examples include robotic handling, vacuum pads for delicate parts, packaging transfer systems, semiconductor-related auxiliary handling, feeder mechanisms, and assembly equipment. Because vacuum strength can be adjusted proportionally through the electrical input, this regulator is especially useful when one line must process more than one product type.
It is also a practical choice for OEMs and maintenance departments that prefer flexible specification matching. The exact code combination of this model already defines a useful configuration: 0 to 10 VDC input, 1 to 5 VDC feedback, 1/4 G ports, and no cable connector. That last point can matter in projects where the user wants to select wiring hardware separately, standardize cable assemblies across a machine family, or integrate the regulator into a custom harness design.
Installation and Selection Considerations
For buyers and engineers, one of the strengths of the ITV2090-31F2N5 is that it sits in a mature, widely recognized SMC family. The ITV range is specifically presented by SMC as an electronic vacuum regulator capable of stepless control in proportion to electrical signals. RS also describes this exact model family as a lightweight, compact vacuum regulator with monitor output capability and IP65-equivalent protection. That combination makes it suitable for installations where both control quality and compact form factor matter.
When selecting this model, users should pay attention to the intended control signal standard, port standard, and wiring strategy. In this case, the exact model code is best suited to systems using 0 to 10 VDC analog command, 1/4 G pneumatic connection, and a configuration where the installer does not require an included cable connector. For equipment builders that already have standardized electrical interfaces, that can be an advantage rather than a limitation.
Conclusion
The SMC ITV2090-31F2N5 is a compact and practical electronic vacuum regulator for automation systems that require proportional, repeatable vacuum control. It combines a -1.3 to -80 kPa regulating range, 0 to 10 VDC input, 1 to 5 VDC analog monitor output, 1/4 G port specification, IP65 equivalent protection, and an approximate 350 g unit weight. These characteristics make it suitable for machine builders, system integrators, and maintenance teams that need dependable vacuum control in a clean and compact format.
From a commercial and technical standpoint, this model is a strong option for vacuum-based automation equipment where stable control, easy electrical integration, and consistent series-level performance are important. It is not just a pneumatic accessory; it is a functional control device that can improve process consistency, simplify machine setup, and support more precise vacuum management across a broad range of industrial applications.
