SMC ZK2C15K5KWA-06 – ZK2A Series Ejector System Vacuum Unit for Manifold, Ejector + Valve + Energy Saving Function

The SMC ZK2C15K5KWA-06 is a high-performance, energy-optimized vacuum unit from the ZK2A Series, engineered for integration into manifold-based ejector systems in industrial automation and manufacturing environments. This single-unit ejector system combines a 2-stage ejector, integrated supply valve, and energy-saving control logic to deliver reliable vacuum generation with minimal compressed air consumption.

Key Features & Technical Specifications

• System Configuration: Ejector system, single unit type, designed for manifold mounting. Ideal for multi-point vacuum handling applications requiring compact, modular vacuum solutions.
• Body/Exhaust Type: A – Single unit body with silencer exhaust. Incorporates a high-noise reduction silencer to minimize operational noise while maintaining high suction flow performance.
• Nominal Nozzle Size: 15 (?1.5 mm). Optimized for efficient vacuum generation with a 2-stage ejector design, providing up to 50% higher suction flow compared to standard SMC 1-stage ejectors.
• Supply & Release Valve Configuration: K – Supply valve: Normally Closed (N.C.); Release valve: Normally Closed (N.C.). Ensures controlled vacuum build-up and release, enhancing process repeatability and safety.
• Energy-Saving Ejector Function: Integrated energy-saving mode automatically cuts off air supply once the target vacuum level is reached. Under SMC’s standard test conditions, this results in up to a 93% reduction in air consumption, significantly lowering operating costs and compressed air demand.
• Vacuum Holding Capability: Features a self-holding type supply valve (N.O. specification) that maintains vacuum even during power loss or system shutdown, provided supply pressure is maintained. Prevents sudden dropping of workpieces, improving safety and process reliability in pick-and-place, clamping, and transfer operations.
• Pressure Switch for Vacuum with Energy Saving Function: R – Digital pressure switch with PNP 1-output, pressure range: –100 to +100 kPa. Enables precise vacuum level monitoring and control with unit selection function for flexible system configuration.
• IO-Link Compatibility: Equipped with an IO-Link compatible pressure switch, allowing full ejector control via a single communication line. Supports remote reading of device information, batch parameter settings, and diagnostics, simplifying integration into Industry 4.0 and IIoT-enabled automation systems.
• Rated Voltage: 5 – 24 VDC. Compatible with standard industrial control voltages, ensuring seamless integration with PLCs and control systems.
• Connector Specification: W – 2 m lead wire with connector for the pressure switch (vacuum with energy-saving function). Pre-wired for quick and reliable connection, reducing installation time and wiring errors.
• Vacuum (V) Port: 06 – ?6 mm one-touch fitting. Facilitates fast and secure connection of vacuum tubing, ideal for pneumatic handling systems using standard vacuum accessories.
• Option a: B – Includes mounting bracket for single unit (nuts and bolts included). Simplifies mechanical installation and ensures secure mounting on panels or frames.
• Option b: – (No additional option). Standard configuration without exhaust interference prevention valve or special port modifications.

Performance & Application Benefits

The ZK2C15K5KWA-06 is engineered for high-efficiency vacuum handling in applications such as robotic end-of-arm tooling (EOAT), automated assembly, packaging, and material transfer. Its 2-stage ejector design delivers faster evacuation times and higher suction flow, improving cycle times and productivity. The integrated energy-saving function reduces compressed air usage by up to 93%, contributing to lower energy costs and improved sustainability in pneumatic systems.

The inclusion of a self-holding supply valve enhances safety by maintaining vacuum during power interruptions, preventing unexpected release of workpieces. The IO-Link interface supports advanced diagnostics, remote parameterization, and predictive maintenance strategies, making this unit suitable for smart factory environments.

Compatibility & Integration

• Compatible with both ejector-based and vacuum pump-based systems.
• Designed for use with standard manifold systems and modular vacuum handling setups.
• Mounting bracket included for secure installation in industrial enclosures or on machine frames.
