Miniature PCB Process Sealed Rotaries Series MRB .. Distinctive Characteristics Double flatted bushing prevents rotation in panel and increases stability. Totally sealed construction, achieved with bination of an interior o-ring, a seal between the frame and base, plus insert molded terminals, prevents contact contamination and allows automated soldering and cleaning. Positive detent mechanism for distinct feel and audible feedback. Break-before-make contact timing with sliding contact mechanism. Metal bushing and frame/bracket provide durability. Panel seal, achieved with use of optional exterior o-ring, conforms to IP67 of IEC60529 Standards. High contact reliability achieved by the self-cleaning contact mechanism. .100” x .100” (2.54mm x 2.54mm) terminal spacing conforms to standard PC board grid spacing for straight and right angle mounting. Actual Size Insert molded terminals lock out flux and other contaminants.
