DIP 14 SERIES REED RELAYS
MSS2 s MSS7 s PRMA s DSS7 s PRME s MVS2 s MVS7
DESCRIPTION
CP Clare’s epoxy molded DIP 14 Series offers a variety of contacts and schematics to meet the needs of a wide range of applications. It features the MVS2/MVS7 models designed for high reliability. The MSS2/7 DIPs are 1 form A relays 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.
FEATURES
s All position mercury contacts on some models s Stable contact resistance over life s 4000 Vac input-output isolation s Bounce free operation s High insulation resistance s Switching speed of 300 Hz s Long life > 1 billion operations s Epoxy molded for automatic board processing
APPLICATIONS
s Automatic test equipment s Process control s Industrial s Telecom s Datacom s High-end security systems s Signaling s Metering
APPROVALS
s UL approval (DSS7 & PRMA) s BSI approval (DSS7 & MSS7) s BS EN 60950 approval (MVS7) s CSA approval (PRMA) s FCC68 approval (MSS2 & MSS7)
