The SMC ITV2090-312BL5 is an electronic vacuum regulator designed for proportional vacuum control in industrial automation systems. It belongs to SMC’s ITV2090/2091 series, a product family developed for applications where vacuum pressure must be adjusted continuously in proportion to an electrical signal rather than by manual setting alone. SMC describes the ITV electronic vacuum regulator series as a solution for stepless control of vacuum pressure in proportion to electrical signals, making it suitable for equipment that demands stable and repeatable vacuum management.
For the ITV2090 series, the standard regulating pressure range is -1.3 to -80 kPa, the enclosure protection is IP65 equivalent, and the standard operating temperature range is 0 to 50°C. The series documentation also lists the approximate product weight for the ITV20 size class as 350 g, which is the applicable weight class for ITV2090 models.
Based on the configuration references available for this exact model, ITV2090-312BL5 is a 24 VDC version with 0 to 10 VDC input, 1 to 5 VDC analog monitor output, Rc thread, flat bracket, right-angle 3 m cable, and kPa display unit. These item-level configuration details are consistent with the ITV coding structure and current distributor listings for this exact part number.

Product Function
The function of the SMC ITV2090-312BL5 is straightforward but technically important: it converts an electrical command signal into proportional vacuum regulation. In other words, when the input signal changes, the regulator adjusts the vacuum level accordingly. This gives machine builders and process engineers a more precise method of vacuum control than conventional manual regulators or simple on/off vacuum switching methods. SMC’s own documentation explains that the series is intended for vacuum control proportional to electrical signals, which is the key operating principle behind the ITV2090 family.
This kind of control is useful in automation environments where different products, materials, or process stages require different suction levels. In many production lines, one setting is not enough. Thin film, cartons, electronic parts, precision components, and lightweight molded items may each need a different vacuum level for stable handling. The ITV2090-312BL5 allows the machine controller to adjust vacuum automatically, which can reduce setup time and improve process repeatability. That makes it practical for modern equipment where product changeover and consistent handling performance are important.
Structural Advantages and Installation Value
One of the practical advantages of the ITV2090-312BL5 is its compact format. SMC’s ITV20 size class has an approximate weight of 350 g, which makes the regulator light enough for compact mounting inside machine frames, control panels, or modular pneumatic assemblies. A lighter proportional regulator can simplify bracket mounting and reduce the burden on support structures, especially in small equipment or systems where components need to be mounted close to the point of use.
The flat bracket included in this configuration improves installation convenience. This is especially useful for OEM machine construction, where consistent mounting layout matters. The right-angle 3 m cable also has practical value. In real machinery, cable routing can be difficult when space is limited or when panel clearances are tight. A right-angle cable helps reduce bending stress and can make the installation cleaner than a straight connector arrangement. The Rc thread connection is also a widely used pneumatic standard, which helps this version fit many existing vacuum systems without unusual adapter requirements.
The series’ IP65 equivalent rating is another relevant benefit. In factory conditions, components are often exposed to dust, moisture, and routine washdown splash conditions. IP65-equivalent protection improves confidence in daily industrial use, particularly in packaging machinery, transfer systems, and assembly equipment. Combined with the specified 0 to 50°C operating range, the ITV2090-312BL5 is positioned as a product that is suitable for practical industrial environments rather than laboratory-only conditions.
Performance Characteristics
The ITV2090 series is designed as a control device, not merely a passive pneumatic fitting. SMC publishes performance characteristics for the family, including 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 engineered for applications where predictable and repeatable vacuum behavior is required.
The same documentation lists temperature characteristics within ±0.12% full span per °C, display accuracy of ±3% full span, and current consumption of 0.12 A or less for the 24 VDC type. For equipment builders, these values are useful because they provide a clearer picture of expected behavior in real operating conditions. In applications where stable suction performance affects product quality or handling yield, those performance specifications matter.

These values come from SMC’s ITV2090/2091 series catalog and apply to the family performance level for electronic vacuum regulation.
Typical Applications
The SMC ITV2090-312BL5 is suitable for many automated systems that rely on vacuum handling or controlled suction. Typical application areas include robotic pick-and-place equipment, packaging machines, transfer systems, vacuum chucks, electronics handling stations, feeder systems, and assembly machinery. In each of these situations, the ability to regulate vacuum proportionally can improve process control compared with fixed-setting alternatives.
This regulator is especially useful where product recipes or handling conditions change regularly. For example, a packaging line may run different carton sizes, or an assembly line may move components with different surface finishes. In those cases, a 0 to 10 VDC input signal allows the PLC or controller to adjust vacuum level automatically. At the same time, the 1 to 5 VDC monitor output can send operational feedback to the control system for monitoring, alarms, or diagnostics. This improves integration quality and supports more intelligent machine control.
Commercial and Engineering Value
From a purchasing perspective, the ITV2090-312BL5 is not just another pneumatic accessory. It is a functional control component that can directly influence machine consistency and product handling stability. For OEM builders, it reduces the need for repeated manual vacuum adjustment. For maintenance teams, a standardized ITV-series part can simplify replacement planning and spare parts management. For integrators, the combination of analog command input, analog monitor output, standard pneumatic thread, bracket mounting, and cable convenience makes this configuration easy to specify in practical projects.
Its moderate size and low approximate weight of 350 g also help when compact machine design is a priority. In many modern automation systems, designers want to shorten pneumatic paths, reduce panel crowding, and simplify service access. A compact electronic vacuum regulator with defined signal interfaces is useful in that context because it supports both mechanical efficiency and control flexibility.
Conclusion
The SMC ITV2090-312BL5 is a compact and practical electronic vacuum regulator developed for industrial systems that require stable, proportional vacuum control. It combines a -1.3 to -80 kPa regulating range, 24 VDC power supply, 0 to 10 VDC input signal, 1 to 5 VDC analog monitor output, Rc thread, flat bracket, right-angle 3 m cable, IP65-equivalent protection, and an approximate 350 g unit weight. These features make it suitable for OEM equipment, system integration, maintenance replacement, and industrial automation projects where repeatable vacuum performance is required.
In practical terms, this model is a strong fit for users who need more than simple vacuum switching. It is built for controlled, repeatable vacuum management, and that makes it valuable in packaging, handling, transfer, and precision automation applications. For buyers who want a vacuum regulator that is compact, electrically controllable, and designed for real industrial use, the ITV2090-312BL5 is a technically sound choice within the SMC ITV family.
