ZK2A12K5RWA-08-B: Intelligent Vacuum Generator System with Integrated Energy-Saving Function

Product Positioning
The ZK2A12K5RWA-08-B is an integrated energy-saving vacuum generator system from SMC’s ZK2A series. It highly integrates a high-efficiency vacuum generator, supply valve, release valve, digital pressure switch with energy-saving function, and silencer into one compact unit. This product is specifically designed for automated handling scenarios requiring significant energy consumption reduction, increased productivity, and intelligent control. It is widely used in industrial fields such as electronic component assembly, automotive parts assembly, and packaging material handling.

Core Highlights: 93% Energy Saving, 50% Efficiency Increase, Smart Integration

• Energy-Saving Technology, Cuts Air Consumption by 93%
  • Once the set vacuum level is reached, the system automatically cuts off the air supply, stopping unnecessary compressed air consumption.
  • Compared to products without energy-saving function, air consumption can be reduced by up to 93%, significantly lowering operating costs and carbon emissions.
• Performance Improvement, Suction Flow Increased by 50%
  • Utilizes an optimized two-stage vacuum generation structure. Suction flow is increased by 50% compared to SMC’s traditional single-stage vacuum generators.
  • More air can be evacuated in the same time, improving production efficiency and shortening handling cycle times.
• Intelligent Integrated Pressure Switch, Precise Control
  • Built-in digital vacuum pressure switch with energy-saving function (indicated by “R” in model), pressure detection range -100 ~ 100 kPa.
  • Output specification is PNP 1 output with unit switching function, flexibly adaptable to different control requirements.
  • Integrated design of switch and generator reduces wiring and installation space.
• Compact & Lightweight Design, Space Saving
  • Compared to conventional products, volume is reduced by 28% (88 cm³) and weight by 59% (81 g).
  • 主体 uses resin material, compact structure, easy to install in confined spaces.
• Low Noise Operation, Improves Work Environment
  • Incorporates a high-efficiency silencer, effectively reducing exhaust noise while also contributing to increased suction flow.
  • Suitable for environments with strict noise requirements, such as laboratories and precision machining workshops.
• Dual Valve Control, Complete Functionality
  • Both supply valve and release valve are Normally Closed (N.C.), enabling dual control for vacuum generation and release.
  • Once the supply valve opens, even if power is cut off, the vacuum state is maintained as long as supply pressure is保持, preventing accidental workpiece drop and enhancing safety.
• Modular Interface, Easy Installation
  • Vacuum (V) port is Ø8mm push-in fitting, Supply (P) port is typically Ø6mm.
  • Option “-B” indicates附带 individual unit mounting bracket (bolts and nuts included) for easy direct fixing to equipment.
