Reliable Exhaust Gas Measurements

Would you like to switch to the US version of our website?



The SMB4CAN is a gateway, over which up to four lambda measurement modules for the SMB bus (e.g. ETAS LA3, LA4), can be made available on the CAN bus.

Following the discontinuation of the SMB support in ETAS INCA®, users of ETAS LA3- / LA4 modules can use the SMB4CAN as a gateway from SMB to CAN. On the CAN bus, the lambda measurement modules can be easily combined with the CAN-based MiniModules from CSM.
