2 1 For Oil . Possible to use this for air and water. Note that the maximum operating pressure differential and flow-rate characteristics should be within the specifications of the fluid used. Series VXD The kinematic viscosity must not exceed 50 mm2/s. The special construction of the armature adopted in the built-in full-wave rectifier type gives an improvement in OFF response by providing clearance on the absorbed surface when it is switched ON. When the fluid is oil.

Add 10 g for conduit type, 30 g for DIN terminal type, 60 g for conduit terminal type respectively. �� Refer to “Glossary of Terms” on page 139 for details on minimum operating pressure differential, the maximum operating pressure differential, maximum system pressure.
