SMC ZK2A10J5ALA-06 ZK2A Series Ejector System Vacuum Unit – Single Unit Ejector with Valve, No Energy Saving Function

The SMC ZK2A10J5ALA-06 is a high-performance ZK2A Series ejector system vacuum unit designed for industrial automation and material handling applications requiring reliable vacuum generation and controlled workpiece holding. This single-unit vacuum ejector integrates a supply valve and is configured without the energy-saving function, making it ideal for continuous-duty applications where uninterrupted vacuum is critical.

Supply Valve with N.O. Specification – Enhanced Safety and Process Reliability

This unit features an integrated normally open (N.O.) supply valve, a key enhancement for fail-safe operation. In the event of a power loss or system shutdown, the valve maintains vacuum hold as long as supply pressure is present, preventing sudden dropping of workpieces. This feature is particularly valuable in pick-and-place, robotic handling, and transfer systems where workpiece integrity and operator safety are paramount. The N.O. configuration ensures process continuity and reduces risk of damage during unexpected power interruptions.

IO-Link Compatible Pressure Switch – Simplified Integration and Diagnostics

The ZK2A10J5ALA-06 includes an IO-Link compatible pressure switch, enabling advanced diagnostics and control via a single communication line. IO-Link support allows for real-time monitoring of vacuum status, device information retrieval, and batch parameter configuration from the control system. This simplifies wiring, reduces cabinet space requirements, and supports predictive maintenance strategies in Industry 4.0 and smart factory environments.

System Compatibility – Flexible Integration with Ejector and Vacuum Pump Systems

Engineered for broad compatibility, this vacuum unit can be seamlessly integrated into both ejector-based and vacuum pump-based systems. Its modular design supports flexible deployment across a range of automation platforms, including assembly lines, packaging machines, and CNC loading systems, where vacuum performance and system interoperability are critical.

Performance Specifications – Optimized for Industrial Applications

• Operating Pressure Range: 0.3 to 0.6 MPa (3 to 6 bar)
• Operating Temperature Range: -5°C to +50°C
• Suction Flow: 44 l/min (at 0.6 MPa supply pressure)
• Exhaust Type: Silencer-equipped exhaust port for reduced noise emissions
• Port Size: G1/8" (standard for ZK2A series)
• Weight: 49.44 g (unit only; excludes mounting hardware)

High-Efficiency Ejector Design – Increased Suction Flow

The ZK2A series ejector core delivers a 50% increase in suction flow compared to standard SMC single-stage ejectors, enabling faster evacuation times and improved handling of porous or leaky workpieces. This enhanced performance supports higher cycle rates and improved throughput in high-speed automation applications.

Noise Reduction and Operational Environment

The unit incorporates a high-efficiency silencer to minimize exhaust noise, contributing to a quieter working environment. This is especially beneficial in enclosed work cells, cleanrooms, and operator-intensive areas where noise control is a design consideration.

Application Suitability – Where This Unit Excels

The SMC ZK2A10J5ALA-06 is well-suited for:

• Robotic end-of-arm tooling (EOAT) for part handling
• Conveyor-based pick-and-place systems
• Automated assembly and insertion equipment
• Machine tending and CNC part loading/unloading
• Applications requiring vacuum hold during power loss

Technical Notes and Installation Guidance

For optimal performance, ensure supply air is clean, dry, and within the specified pressure range. Use appropriate filtration (e.g., 5 µm filter) and lubrication (if required by system design). Mount the unit securely using the provided mounting features to minimize vibration and ensure long-term reliability. Refer to the SMC ZK2A series technical datasheet and installation manual for detailed porting, wiring, and IO-Link configuration instructions.
