SMC ZKJ vacuum manifold with ejector system

SMC Corporation’s ZKJ vacuum manifold with ejector system is Profinet-enabled. Other features include valve protection functionality, IP65 rating for dust and water jets and the ability to control up to 16 ejectors with a single manifold.

Since the ZKJ series supports Profinet no I/O unit is required.

The ZKJ series also reduces air consumption by up to 90% due to an energy-saving function. A built-in check valve maintains vacuum pressure to reduce the use of compressed air and an integral pressure sensor monitors vacuum pressure to automatically turn off the supply valve upon reaching the set value. In the event of leaks, the supply valve will reactivate to increase vacuum pressure.

The normally-open supply valve ensures the work piece remains in vacuum in the event of an emergency stop or power failure (assuming air pressure continues).

Available in various nozzle diameters and suction flow rates for use in sectors such as automotive, machine tool, food, beverage, medical, pharmaceutical and packaging, the ZKJ series offers a maximum vacuum pressure of -89 kPa and low noise levels down to 52 dB.
