Auxiliary Contacts Front and Side Mounted
A total of six auxiliary contacts are available to be used with
the mini control line.
Front mounted auxiliary contacts are available in three
contact configurations (1NO-1NC, 2NO and 2NC) and can be
screw mounted to non-reversing and reversing contactors
with screw pressure plate terminals only.
Side mounted auxiliary contacts are available for the
miniature control product line in three terminal versions:
screw pressure plate, quick connect and solder pin. The
side mounted auxiliary is mounted to the left side of nonreversing contactors without tools. Only one side mounted
auxiliary can be mounted on these products.
