SF-Y Series Relays

Panasonic’s SF-Y Series Relays are characterized by their small size and flat profile in a variety of contact arrangements. These Relays feature reinforced insulation according to EN 60664-1.

SF-Y Series Relays can be used in many applications, including emergency stop switches, machine tools, elevators, escalators, and safety control units.

Features of the SF-Y Series

Forcibly Guided Contact Structure That Is Mechanically Coupled So That Contact Welding Can Be Detected Easily
Flat Profile: 14.5 (H) mm
6-poles With Different Normally Open And Normally Closed Contact Configurations
Reinforced Insulation According To EN 60664-1
