The SMC ITV2090-212L5 is an electronic vacuum regulator designed for proportional vacuum control in industrial automation systems. It belongs to the SMC ITV2090/2091 series, a product family developed for stepless control of vacuum pressure in response to electrical signals. In SMC’s official catalog, the ITV2090/2091 series is presented as an electronic vacuum regulator line intended for vacuum pressure control in proportion to electrical input, making it suitable for machines that require adjustable and repeatable vacuum performance rather than simple manual setting.
According to SMC’s official order-code table, the model code ITV2090-212L5 decodes as follows: 24 VDC power supply, 0 to 5 VDC input signal, switch output / NPN output, 1/4 port size, Rc thread, right-angle 3 m cable, no bracket, and kPa display unit. The same official documentation states that the ITV2090 pressure range is -1.3 to -80 kPa.
For practical reference, Motion’s product listing for this exact part number also identifies ITV2090-212L5 as an SMC electronic vacuum regulator with 1/4 in inlet port, Rc inlet thread, Rc outlet thread, and a vacuum range of about -0.19 to -12 psi, which is consistent with the official -1.3 to -80 kPa series range.

Product Function
The core function of the SMC ITV2090-212L5 is to regulate vacuum pressure in direct proportion to an electrical control signal. In practical terms, this means the regulator allows a PLC, controller, or automation system to change vacuum level electronically without manual readjustment. That is especially useful in machines where different products, materials, or operating steps require different suction levels during the same production cycle.
Because this model uses a 0 to 5 VDC input signal, it is particularly suitable for equipment designed around voltage-based analog control. In many automation systems, a 0 to 5 VDC command signal is used when the designer wants simple low-voltage proportional control. The regulator then converts that signal into controlled vacuum output inside the published range of -1.3 to -80 kPa.
Unlike a fixed vacuum valve or manually adjusted regulator, the ITV2090-212L5 can help equipment respond more flexibly to changing process conditions. If a production line handles light film, cartons, plastic parts, or fragile components with different surface characteristics, the required vacuum holding force may vary. An electronic vacuum regulator makes that adjustment faster and more repeatable, which can reduce handling errors and improve machine consistency. This operating concept is exactly what SMC positions the ITV2090/2091 family to do.
Structural and Installation Advantages
One practical advantage of the ITV2090-212L5 is its compact format and moderate weight. SMC lists the ITV20 class at approximately 350 g without brackets, which makes it suitable for compact machine frames, pneumatic panels, and modular automation assemblies. In actual equipment design, a lighter regulator is easier to mount and can help reduce mechanical congestion in areas where multiple control components have to share limited installation space.
This exact model also includes a right-angle 3 m cable, which is useful when space around the mounting area is restricted. A right-angle cable can simplify wiring routes and reduce bending stress compared with a straight cable exit. SMC’s accessories table confirms the right-angle 3 m cable option for this family.
The Rc thread and 1/4 port size are also practical installation features. These are widely recognized connection standards in industrial pneumatic systems, so this regulator can often be integrated without unusual conversion hardware. The fact that the model is specified without bracket is also meaningful. For OEM machine builders or retrofit users who already have their own mounting method, a no-bracket version can be more convenient than buying a bracketed version and removing unused hardware.
Environmental and Operating Characteristics
SMC’s standard specification for the ITV2090/2091 series lists an operating temperature range of 0 to 50°C and IP65-equivalent enclosure protection. These are important values because they show that the regulator is intended for real industrial use, not only for clean laboratory conditions. In packaging, transfer, and assembly systems, exposure to dust, incidental moisture, and daily machine vibration is common. IP65-equivalent protection gives users more confidence in long-term installation within working equipment.
The series also uses a digital pressure display with kPa unit selection in this model. For users and maintenance personnel, this makes setup and observation easier during commissioning, adjustment, and troubleshooting. The exact “5” code in the part number corresponds to kPa display unit, according to the official SMC ordering chart.
Performance Characteristics
The ITV2090/2091 family is designed as a control component, not merely a passive pneumatic device. The official SMC specification lists the following control characteristics for the series: 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 series is engineered for stable and predictable vacuum regulation.
For many automation applications, that matters directly. In robotic vacuum picking or transfer handling, unstable vacuum behavior can lead to dropped parts, inconsistent gripping force, or poor release timing. A regulator with defined linearity and repeatability helps reduce those risks. The SMC data also lists temperature characteristics within ±0.12% full span per °C and an IP65-equivalent enclosure, reinforcing that the product is intended for controlled performance in normal industrial conditions.

Typical Applications
The SMC ITV2090-212L5 is suitable for a wide range of industrial applications that use controllable vacuum. Typical examples include robotic pick-and-place systems, packaging machinery, electronics handling equipment, feeder units, transfer systems, vacuum workholding stations, and light assembly automation. In all of these applications, the ability to adjust vacuum through an electrical input signal provides more process flexibility than a manually adjusted regulator.
This particular model is especially appropriate where the control system is based on 0 to 5 VDC analog command and where a switch output / NPN output is preferred instead of analog monitor voltage. That output style can be useful for machine interlocks, simple status monitoring, or PLC-based discrete signal handling. In some systems, a discrete NPN output is easier to integrate into ladder logic than an analog feedback signal, especially where the machine designer primarily needs threshold or status confirmation.
Because the unit is compact, uses common port standards, and includes a right-angle cable, it can also be a practical choice for retrofit work. If an older machine requires improved vacuum adjustability but has limited installation space, this configuration offers a workable balance of compact size, controlled performance, and standard industrial connections.
Commercial and Engineering Value
From a commercial standpoint, the ITV2090-212L5 is more than a general-purpose pneumatic accessory. It is a functional automation component that can improve machine consistency, support product changeovers, and reduce manual adjustment time. For OEM machine builders, that can translate into better process control and easier integration with existing PLC architecture. For maintenance teams, it provides a defined SMC solution with clear part-number structure, standard port size, and known electrical interface.
From an engineering standpoint, this model combines several practical features in one package: 24 VDC supply, 0 to 5 VDC input, NPN switch output, 1/4 Rc ports, right-angle 3 m cable, IP65-equivalent protection, and approximately 350 g body weight. That combination makes it suitable for modern automation equipment where compactness, reliability, and straightforward integration all matter.
Conclusion
The SMC ITV2090-212L5 is a compact and practical electronic vacuum regulator built for proportional vacuum control in industrial automation systems. It offers a -1.3 to -80 kPa regulating range, 24 VDC power supply, 0 to 5 VDC input signal, switch output / NPN output, 1/4 Rc port specification, right-angle 3 m cable, kPa display unit, IP65-equivalent protection, and an approximate 350 g product weight.
For users who need stable, electrically controlled vacuum management rather than manual adjustment, this model is a strong choice within the SMC ITV2090 family. It is well suited to packaging, material handling, pick-and-place, transfer, and general-purpose automation applications where reliable vacuum regulation improves process performance and operational consistency.
