Coval presents the Lemax IO series, mini vacuum pumps with IO-Link communication that integrate all the necessary functions for optimizing vacuum management in a smaller size. The pumps combine performance, energy savings and communication to adapt to multiple applications.

The IO-Link communication interface of the mini vacuum pumps provide fast and cost-effective installation, continuous diagnostics, centralized configuration and efficient communication with higher level protocols such as Ethernet/IP, Profinet and EtherCAT. The Lemax IO vacuum pump is designed to permanently communicate with its environment, ready to play its part to the fullest in Industry 4.0. The ASC (Air Saving Control) technology also offers up to 90% of energy savings, providing intelligent vacuum regulation by stopping air consumption when the set vacuum level is reached.

The pumps are easy to use and integrate all the main functions in a single module: pressure control, pilot solenoid valves, non-clogging through-type silencer, electronic vacuum switch, M8 connector (Plug & Play direct connection), and adjustable blow-off. The reduced size and weight (130 grams) of the series enables it to be connected as close as possible to the suction cups for reduced gripping time without drop in pressure.

The modularity of the Lemax IO fit the needs of integrators and users. It is available in three standard nozzle diameters (1; 1,2; 1,4 mm) allowing an intake flow of 29 up to 70 Nl/mn (85% maximum vacuum). It can be provided with a normally closed (NC) or normally open (NO) solenoid valve. This alternative is recommended for applications where safety of the gripped piece must imperatively be ensured during an unexpected power failure, this even in the case of leakage (fail-safe). It is finally possible to combine several Lemax IO on island assemblies with a single pressure supply.
