SMC Vacuum Generator for Use With ZK2 Series Vacuum Ejectors ZK2A12K5CLA-08, Pneumatic, 12-24V DC

SMC ZK2A12K5CLA-08 Vacuum Generator is designed for industrial automation, enabling precise vacuum generation inline with pneumatic systems. It integrates a two-stage ejector with pilot-operated supply and release valves, a digital vacuum pressure switch with selectable output functions, and a silencer exhaust configuration.

This vacuum generator achieves a maximum vacuum performance of -91 kPa, ensuring reliable suction for operations such as pick-and-place grippers, vacuum handling of electronic components, pneumatic conveyors, and vacuum clamping during machining or inspection tasks.

The device operates within a supply pressure range of 0.3 to 0.6 MPa, optimising air consumption at 58 l/min to balance performance and energy efficiency. Noise emission is limited to 75 dB, contributing to a safer working environment compliant with workplace acoustic standards.

It runs from a 12 to 24 V DC electrical supply, featuring reverse-polarity protection and a power consumption of up to 40 mA for the switch, plus 0.4 W for the valve. The integrated digital vacuum pressure switch offers a resolution of 0.1 kPa and PNP signalling outputs capable of 80 mA max load.

The filtration system includes a 30 μm element rating and 510 mm² filtration area at the suction inlet, supporting clean compressed air requirements for reliable operation. The switch response time is 2.5 milliseconds or less, with adjustable anti-chatter timings from 20 to 2000 milliseconds, allowing cycle stability tuning.

Maximum vacuum performance of -91 kPa ensures strong and reliable suction. Supply pressure operating range is 0.3 to 0.6 MPa for stable and efficient input. Air consumption is calibrated at 58 l/min, balancing efficiency and power.

Low noise level of 75 dB meets workplace acoustic safety standards. Digital vacuum pressure switch features 0.1 kPa increments for precision control. Switch output with PNP 2 outputs supports signalling with 80 mA load capacity.

Runs on 12-24 V DC with reverse-polarity protection consuming up to 40 mA. Includes 30 μm filtration element ensuring clean air intake. Fast switch response time of 2.5 ms with adjustable anti-chatter timings.

This Vacuum Generator is ideal for industrial, manufacturing, and laboratory pneumatic applications requiring precise vacuum control. It is especially suited for automated assembly lines, pneumatic conveyors, and vacuum clamping in machining processes.
