<strong>Linear</strong> Positioner Environm<strong>en</strong>tal ConsiderationsL I N E A R P O S I T I O N E R SEnvironm<strong>en</strong>tal conditions are an important designconsideration wh<strong>en</strong> selecting a Kollmorg<strong>en</strong> <strong>Linear</strong> Positioner.Kollmorg<strong>en</strong> units are self-contained systems which areprotected from “direct contact” with harsh <strong>en</strong>vironm<strong>en</strong>tsby an aluminum housing with a durable anodized and epoxycoated surface finish. However, extreme conditions can havean adverse effect on cylinder operation and life. Factors suchas extreme temperature, liquids or abrasive contaminants(gaining internal access) can impede performance and causepremature wear of mechanical parts. Review the informationbelow wh<strong>en</strong> sizing your application to choose appropriateoptions or protective measures.Primary Environm<strong>en</strong>tal Factors• Temperature• Liquid contaminants• Particle contaminantsRod TypeTemperature• N2 electric cylinders are rated for use betwe<strong>en</strong> 0 and 60°C (32 to 140°F).• EC electric cylinders are rated for use betwe<strong>en</strong> -30 and 70°C (-22 to 158°F)Particle and Liquid Contaminants• N2 series electric cylinders are protected against dust but are not protected againstdirect water (or any liquid) contact. Liquid or moisture can gain access into the housing,ev<strong>en</strong>tually corroding internal compon<strong>en</strong>ts.• EC electric cylinders are sealed and gasketed and are rated to IP54. They are protectedagainst dust and light water sprays and splashing.Protective Boot OptionThe PB option is available for EC electric cylinders andincreases the positioner’s resistance to liquids. The diagramto the right shows a typical installation of an EC with the PBoption. This option protects the positioner to IP65. Note thatsome motor options are not protected to this level. The PBoption is not available with R-series Rodless positioners.Custom Environm<strong>en</strong>tal OptionsKollmorg<strong>en</strong> has over 30 years experi<strong>en</strong>ce designing customlinear positioners. We have designed fully <strong>en</strong>capsulated linearpositioners for Corrosive, Food Processing, and Washdown<strong>en</strong>vironm<strong>en</strong>ts, and have experi<strong>en</strong>ce designing for Cleanroomcompatible <strong>en</strong>vironm<strong>en</strong>ts.
