No. The CAE tries to make the encoder (i.e. mapping from input to hidden layer) have the property of locality, i.e. small changes in input lead to small changes at hidden layer. This is a nice property because it means the mapping is not too sensitive, which should help it generalise beyond the training data.
(There is an extra complication: the CAE tries in particular to enforce locality along the direction of the low-dimensional manifold which all autoencoders assume is present in the input data. I find this part a bit harder to explain.)
