Electromechanical and semiconductor relays

SFY series: low profile

These high power, low profile devices suit safety and control applications. Broad line-up of contact types includes 2a2b, 3a1b, 4a2b and 5a1b styles.
SFY relay

Power and safety under tough conditions

A strong magnetic circuit, robust and thick copper contacts combined with an elaborate production process are the ingredients for SFY relay‘s high power capability. Up to 6A and high AC15 / DC13 values on both NO and NC side allow direct switching of high loads. On the other side, gold clad contacts on request and a high contact reliability serve the requirements of low level loads. The rotating armature system as well as energy efficient polarized technology render SFY an appropriate choice for particularly harsh and demanding conditions.
