The 605DM Series is a weather resistant, general purpose differential pressure switch with DPDT. It is modeled after the 604 Series, designed specifically for high ingress and corrosion resistant applications. It has a modified face down side port electrical connection preventing any liquids from seeping into the inner workings of the switch. The 605DM Series is easily mounted to bulkheads and ideal for extreme wet conditions, rated to NEMA 4X and IP66. Applications include nonhazardous environments such as: • Power Generation • Rail Car • Fluid Management • Manufacturing Process • Utilities, Water Treatment and Waste • Chemical Refining and Processing • Heavy Vehicles • Safety Systems Environmental Approvals IP65, IP66, NEMA 4, NEMA 4X, NEMA 13, NACE, RoHS Industry Industrial Instrumentation Pressure Switch Environment Non-Hazardous Certification Agency Approvals CE, CRN, CCC Operating Temperature Range -40° to 186 °F Process Connection Fitting Size Female 1/4" NPT Process Connection Material Aluminum Housing Enclosure Aluminum Electrical Connection Female 1/2" NPT Electrical Switch Type DPDT Voltage Electrical Rating VAC 0 to 250 VAC, 251 to 480 VAC Amperes Electrical Rating 0.5 to 5 A Fixed or Adjustable Set Point Adjustable Presetting Factory Set, Not Factory Set Tagging Mylar, Stainless Steel Accessories Manifold Increasing Pressure Range 1.4 to 18 PSID, 6 to 75 PSID Decreasing Pressure Range 0.5 to 17.1 PSID, 2 to 71 PSID Pressure Type Differential Media Oil Based, Non-Oil Based Increasing Pressure Ranges 1.16 – 2.99 PSI, 3 – 180 PSI Decreasing Pressure Ranges 0 – 1.15 PSI, 1.16 – 173 PSI Maximum System Pressure 400 Maximum Proof Pressure 750 Process Connection Seal O-Ring Sealed Diaphragm Diaphragm Polyimide O-ring Viton
