Panasonic Electric Works SFS Series

Main Title

SFS series polarised relays

Mixed Media

Negligible dissipation power, slim design, high switching current – numerous industrial applications repeatedly place the same demands on a relay.

The SFS relay family with forcibly guided contacts complying with IEC 61810-3 (Type A) from Panasonic Electric Works fulfills many wishes of PC board design engineers: at just 13mm in width and 24mm in height, the relay boasts a nominal switching current of 6A at 230VAC/30VDC, and thanks to its polarised drive system, the coil dissipation power is very low.

For the 4-pin version, which is 40mm in length and available with contact arrangements of 2a2b and 3a1b, the coil dissipation power is a mere 360mW. The 55mm long, 6-pin version's coil dissipation power is just 500mW; it is available with contact arrangements of 4a2b, 5a1b and 3a3b. Each type offers an optional, integrated status LED.

An impressive, typical turn-on time of 8ms and highly functional shock resistance of at least 20g round off the technical parameters.

PC board and DIN-rail terminal sockets are available as accessories for all SFS relays.
