PRESSURE COMPENSATION DEVICE DA 284 | IP66 / IP68 In enclosures and housings with a high protection class, differential pressure happens due to internal and exter - nal temperature changes. In the event of negative pressure, dust and humidity can be drawn into the enclosure through the seals on the doors. This can cause condensation when the air in the enclosure cool down. The easy-to- fit DA 284 pressure compensation device enables pressure compensation with protection class IP66 (M12: IP66/ IP68). Additionally, the watertight membrane inside the pressure compensation device allows humidity to escape from the cabinet at overpressure, while preventing water, humidity or dirt intrusion at under pressure. > High degree of protection > Waterproof membrane > Easy to install Photo: DA 284, M12 Photo: DA 284, M40 TECHNICAL DATA Mounting thread M40 x 1.5 or M12 x 1.5 with nut Torque M40: 5 Nm, M12: 0.5 Nm Depth in enclosure M40: approx. 16mm, M12: approx. 8 mm Sealing sealing gasket NBR Filter waterproof membrane Dimensions M40: Ø 60 x 37 mm, M12: Ø 17 x 17.5 mm Fitting position variable Note Material adheres to limit values in accordance with RoHS3 Installation: Make cut-out Ø 40.5+0,5 mm in enclosure wall for size M40 or Ø 12+0,2 mm for size M12, and mount pressure compen- sation device with nut. Please make sure that the sealing gasket is put in place on the outer side panel of the enclosure. Art.
