In this paper we characterize a class of normal (isometric, coisometric, unitary, hyponormal) singular Cauchy integral operators with operator-valued (or matrix-valued) symbols on vector-valued (or class="mathmlsrc">class="formulatext stixSupport mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0022247X16305893&_mathId=si1.gif&_user=111111111&_pii=S0022247X16305893&_rdoc=1&_issn=0022247X&md5=05eabc58ea9409ed3ed331d401e1d464" title="Click to view the MathML source">Cnclass="mathContainer hidden">class="mathCode">-valued) class="mathmlsrc">class="formulatext stixSupport mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0022247X16305893&_mathId=si2.gif&_user=111111111&_pii=S0022247X16305893&_rdoc=1&_issn=0022247X&md5=ef1ee893f186b1a4be91930118757a0f" title="Click to view the MathML source">L2class="mathContainer hidden">class="mathCode"> spaces.
