SMC ZK2 Series Vacuum Generator, 72L/min Maximum Suction Flow, -91kPa Maximum Vacuum Pressure - ZK2G12K5CLA-08

This vacuum generator is a Compact pneumatic ejector unit designed for automated handling and pick-and-place operations in industrial environments. It draws a vacuum from compressed Air to provide reliable suction for components and tooling, operating across common factory temperatures and compatible with standard pneumatic supplies.

Features & Benefits

• Maximum suction flow 72 L/min providing Rapid pick-and-place cycle times
• Peak vacuum capability -91 kPa enabling a secure grip on varied parts
• Nozzle diameter 1.2mm offering focused suction for small components
• Supply pressure tolerance 0.6 MPa supporting typical shop Air systems
• Exhaust port 6mm with noise-reducing silencer for quieter operation
• Vacuum port 8mm one-touch fitting for fast installation

Applications

• Suitable for automated PCB component pick-and-place stations
• Ideal for machine tending in electronics assembly lines
• Used with end-of-arm tooling for lightweight part transfer
• Can be used for material handling of delicate substrates
• Suitable for vacuum pick systems in mechanical assembly cells

What electrical supply is required for sensor and valve functions?

The unit accepts a 12 to 24V DC supply with reverse-connection protection and low ripple, and the valve coils operate at 24V DC.

How does the control output communicate vacuum status?

Two PNP open-collector outputs provide switching signals with a maximum load current of 80 mA and a residual voltage of 2V or less.

What filtration and protection are provided for the suction side?

A built-in suction filter with a nominal filtration rating of 30 μm and a filtration area of 510mm² protects internal passages from particulate ingress.

How does the pressure switch display and resolution perform?

The digital display is a 3½-digit red LED with 0.1 kPa smallest increment and display accuracy of ±2% FS ±1 digit at 25 ±3 °C.

What mechanical robustness can be expected in industrial use?

The unit withstands vibration up to 20 m/s² and impact up to 100 m/s², with a proof pressure of 500 kPa and an IP40 enclosure.
