PRMA/MSS2/MVS2
DIP 14 Series Reed Relays
DESCRIPTION
SRC Devices’ epoxy molded DIP 14 Series offers a variety of contacts and schematics to meet the needs of a wide range
of applications. The MSS2 is a 1 form A relay equipped with the MYAD all-position mounting switch. With switching up to
50 Watts and a 4000V isolation option, the DIP 14 Series is a relay package that allows for automatic insertion directly on
PCBs as well as insertion into standard 14 pin DIP sockets.
