The 1617748-5 is a polarized single-side stable design, where the flux from a permanent magnet provides the armature holding force in the deactivated state and its flux path is switched and combined with the coil flux in the operated state. This results in appreciably increased contact pressure in both states over that of a spring return non-polar design.Hermetically sealedAll welded constructionBalanced forcePermanent magnet driveSilver cadmium oxide with gold plating contactsApplicationsIndustrial, Defence, Military & Aerospace, Avionics
