KO4700 The housing shell has molded printed circuit board guides to save time when inserting Series printed circuit boards, prevent misconnections and to keep the boards from moving. Integral tabs on the bottom of the shell further help to hold boards in place, eliminating lateral movement. KO4700 housing shells can be potted. Printed circuit boards can be mounted in three ways: Behind the Front Cover Horizontally Vertically Depending on the enclosure type, one board can be mounted directly behind the front cover (parallel to the DIN rail).Boards can also be mounted horizontally (parallel to the DIN rail) or vertically (perpendicular to the DIN rail). (Refer to the Ordering Pages for board patterns and location of board guides.) Ideal for industrial applications.
