MSS4/MVS4
SIP Series Reed Relays
DESCRIPTION
The high performance MSS4 and MVS4 models provide bounce free operation and offer a more durable contact when
switching capacitive or inductive loads. Both are capable of switching loads up to 50 watts.
FEATURES
•High reliability switching
•3V operate option available
•Long operating life at low levels (>1 billion operations)
•High isolation between input and output (2500V)
•Optional internal diode & N.C. option
APPLICATIONS
•ATE
•Telecom
•Matrix requirements
•Instrumentation
•Data acquisition
