Hi,

Problem maybe is funny for experienced person but I struggle to figure out what the abbreviations on SICK ultrasonic sensor mean. There is L+ and Q (which i know) and M, MF and NC and those I am not sure. Can anybody told me what they mean and how to connect that sensor to make it work?

 

Check the SICK website for the type of sensor you are using. For instance, for the UM18-5111x, the data sheet gives detailed instructions as to how MF can be used to "teach-in" the switching distances for the object to be sensed.

NC is probably No Connection as in one of the variants the terminal is used for a second output. From the colours, L+ is the positive supply and M is the negative.

Hi,

In the world of Sick (and many others) the NC means Normally Closed output. The opposite is NO which stands for Normally Open output.

 

So I successfully connected my ultrasonic sensor. I email SICK and they told me that NC means no connection (bruce is right) MF multifuntcion. M is a common in this case 0V. Thank You
