Description
The E34 Series 30.5 mm pushbutton linefeatures the same rugged die castconstruction of our 10250T line with anadditional two layer 100% solid thermosettingcathodic epoxy coating. This coating providesa flat black smooth, consistent, corrosionresistant surface that has passeda demanding 600 hour salt spray test. (Theindustry standard for this 4X test requiresonly 200 hours.) E34 cathodic coating is notrecommended for use in applications where exposure to ultraviolet light exists—useNEMA 4X 10250T operators.
The contact blocks feature enclosed silvercontacts with pointed "reliability nibs" forreliable performance from logic level up to600V. To ensure reliable switching, nibs bitethrough oxide which can form on silvercontacts, eliminating the need for expensivelogic level blocks for most applications.The E34 Series pushbutton operators offer front of panel drainage viaholes in the operator bushing. Hidden fromview by the mounting nut, these holesprevent buildup of liquid inside theoperator, which can prevent operationin freezing environments. The holes alsoprovide a route for escaping liquid in highpressure washdowns, effectively relievingpressure from the internal diaphragm seal,ensuring reliable sealing in applicationseven beyond NEMA 4.
