SMC ZL6HN04-K15LOZ-VBW Multistage Vacuum Ejector with Energy-Saving Pressure Switch

High-Performance Vacuum Generation for Industrial Automation

The SMC ZL6HN04-K15LOZ-VBW is a premium multistage ejector from the ZL3/ZL6 series, engineered for demanding industrial automation and material handling applications requiring reliable, energy-efficient vacuum generation. This model delivers a maximum suction flow rate of 600 L/min (ANR) while incorporating advanced energy-saving technology to reduce operational costs and compressed air consumption.

Technical Specifications

Vacuum Performance: Achieves vacuum pressures down to ?93 kPa with a maximum suction flow rate of 600 L/min (ANR). The multistage ejector design ensures consistent vacuum generation across varying operating conditions, making it ideal for high-speed pick-and-place systems, material transfer applications, and automated packaging equipment.

Energy Efficiency: Features an integrated pressure switch with energy-saving functionality that reduces air consumption by up to 91% compared to conventional ejector designs. This intelligent control mechanism actively monitors vacuum levels and modulates ejector operation, minimizing waste while maintaining peak performance. Supply pressure operates in the range of 0.2 to 0.6 MPa (0.35 MPa standard specification).

Port Configuration: Equipped with standardized one-touch fitting connections (N04 / NPT 1/2 thread size) for the vacuum (V) and exhaust (E) ports, facilitating rapid installation and reconfiguration in production environments. Port block design accommodates both top and side mounting orientations for flexible system integration.

Advanced Control & Monitoring

Pressure Switch with Remote Sensing: Integrated vacuum pressure switch provides PNP open collector output with configurable response time (2.5 ms or less with anti-chattering function: 20, 100, 500, 1000, 2000 ms options). Optional remote sensor unit enables vacuum monitoring at the point of application, with output voltage ranging from 1 to 5 V (±2.5% F.S.) or 4 to 20 mA output current.

IO-Link Compatibility (New): This model supports IO-Link protocol for single-line communication with control systems, enabling real-time device information retrieval and batch parameter settings without additional wiring. This feature streamlines system commissioning and diagnostics while reducing installation complexity.

Compact Design: Weighs approximately 275–320 grams (base unit with valve and pressure switch), representing a 60% weight reduction versus previous generation models. The minimal footprint allows for space-constrained installations while maintaining full functionality and accessibility for maintenance.

Operational Reliability

Durability & Environmental Rating: Operating temperature range of 5–50°C (no condensation) with humidity tolerance of 35–85% RH. Vibration resistance rated to 20 m/s² (with pressure switch). Short-circuit protection and repeatability of ±0.2% F.S. ±1 digit ensure stable, repeatable vacuum performance across production cycles.

Installation & Compatibility: Features pilot-operated valve technology with adjustable cracking pressure and integrated pressure gauge option for system diagnostics. Lead wire assemblies available with 2-meter standard length and connector options to simplify panel integration.

Ideal Applications

Recommended for robotics automation, semiconductor wafer handling, electronics assembly, food and beverage processing, pharmaceutical packaging, and logistics automation where energy efficiency, compact form factor, and intelligent control are critical parameters.

Standards Compliance

CE/UKCA-compliant design meets international pneumatic safety and electromagnetic compatibility requirements. RoHS compliant materials and construction ensure environmental responsibility and regulatory compliance across global markets.
