The SMC ITV2090-322L5 is an electronic vacuum regulator designed for accurate and proportional vacuum control in industrial automation systems. It belongs to the well-known SMC ITV2090/2091 series, a product family developed for applications that require vacuum pressure to be adjusted continuously in response to an electrical input signal. SMC presents the ITV series as a regulator platform for stepless control of vacuum pressure in proportion to electrical signals, which makes it especially useful in equipment where stable suction performance and repeatable process control are required.
For the ITV2090 family, the standard regulating pressure range is -1.3 to -80 kPa, and the series is designed for IP65-equivalent protection with an operating ambient and fluid temperature range of 0 to 50°C. The catalog also lists a weight of approximately 350 g for the ITV2090/2091 size class. That weight is the most reliable catalog-level figure for this product family and is appropriate for general product introduction, quotation support, and installation reference.
Based on current product listings for the exact part number ITV2090-322L5, this configuration is a 24 VDC model with 0 to 10 VDC input, NPN switch output, Rc thread, no bracket, right-angle 3 m cable, and kPa display unit selection. These suffix details are consistent with current distributor references for this specific model and align with the ITV series ordering structure.

Product Function
The SMC ITV2090-322L5 is used to regulate vacuum pressure in direct proportion to an electric command signal. This is a major advantage in automated systems because it allows the machine controller to change the vacuum level dynamically instead of relying on manual adjustment. In modern industrial equipment, that capability is important when the same production line handles different materials, different part sizes, or different operating conditions. A proportional vacuum regulator makes the system more flexible and can reduce the time required for product changeover.
This model is particularly useful in processes where vacuum must be applied with control rather than simply turned on and off. In many machines, excessive suction can damage delicate workpieces or make release difficult, while insufficient suction can cause unstable handling. By allowing precise electrical control of vacuum pressure, the ITV2090-322L5 helps engineers fine-tune the balance between holding force and safe product handling. That is one of the main reasons electronic vacuum regulators are widely used in sophisticated automation systems.
Product Structure and Configuration Value
A practical strength of the ITV2090-322L5 is its compact design. With a catalog weight of approximately 350 g, it is light enough to be mounted conveniently in machine frames, equipment panels, or modular pneumatic assemblies. A lighter regulator is easier to integrate into compact systems and can help reduce installation constraints in equipment where space is limited. In modern automation design, a compact vacuum regulator is valuable because it can be placed closer to the point of use, helping simplify pneumatic routing and overall machine layout.
The suffix configuration of this model is also important. The 0 to 10 VDC input signal is widely accepted in industrial control systems and can be driven by PLC analog output modules, industrial controllers, or other standard automation hardware. The NPN switch output version is useful when users want a digital monitoring signal instead of analog feedback. That makes this model attractive in systems where the designer wants a simpler status output for interlock, alarm, or control verification rather than a continuously varying monitor voltage.
The Rc thread connection is another practical feature because it matches many pneumatic installation standards used in industrial machinery. The right-angle 3 m cable is especially useful in real machine layouts, where cable direction and bending space can affect ease of installation. A right-angle cable can help reduce cable stress and support cleaner routing in control cabinets or enclosed equipment structures. The without bracket configuration is suitable for users who already have a standard mounting arrangement or want to integrate the regulator into a custom machine design.
Performance Characteristics
The ITV2090 series is not merely a simple pneumatic component. It is a control device designed with measurable performance characteristics. According to the series specification, the family provides 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 values indicate that the regulator is engineered for repeatable and controlled vacuum performance, which is critical in machines where suction stability directly affects productivity or product quality.
The same catalog data also 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. These series-level values help explain why the ITV2090 range is used in industrial equipment rather than only in laboratory or low-demand applications. The performance profile supports automated systems that need stable vacuum control over time and under changing ambient conditions.

Typical Applications
The SMC ITV2090-322L5 is suitable for many industrial systems that use vacuum for gripping, positioning, moving, or holding workpieces. Common application examples include robotic pick-and-place equipment, packaging lines, vacuum transfer systems, semiconductor-related handling equipment, assembly machines, feeder units, and workholding stations. In these environments, the ability to regulate vacuum electronically helps improve consistency across different products and operating conditions.
This model is especially useful where a machine must handle different surface textures, different weights, or different part geometries. For example, a packaging system may need one vacuum setting for thin film and another for cartons. A pick-and-place unit may need gentler suction for fragile parts and stronger holding force for more rigid products. The ITV2090-322L5 allows those vacuum settings to be adjusted from the electrical control system, reducing manual intervention and improving process repeatability.
The NPN switch output configuration also fits machines where discrete signal monitoring is preferred. In some systems, a digital output is easier to integrate into PLC logic than an analog feedback signal. That can simplify programming, fault detection, and equipment status confirmation. As a result, this specific variant can be a better choice for users who want practical digital monitoring along with proportional vacuum control.
Commercial and Engineering Advantages
From an engineering standpoint, the ITV2090-322L5 offers a useful combination of compact size, practical signal compatibility, and reliable series performance. The product’s 24 VDC power supply, 0 to 10 VDC input, Rc port format, and right-angle 3 m cable make it straightforward to integrate into standard industrial control systems. At the same time, the IP65-equivalent protection supports installation in real factory environments where exposure to dust and moisture is part of normal machine operation.
From a purchasing perspective, this model is more than a general pneumatic fitting. It is a functional automation component that can directly influence machine stability and handling quality. For OEM machine builders, it supports flexible recipe-based control. For maintenance teams, it provides a defined and recognized SMC solution for vacuum regulation replacement. For distributors and system integrators, it represents a commercially relevant product because it combines compact mechanical design with practical electrical and pneumatic configuration.
