SIP SERIES REED RELAYS
DESCRIPTION
SIL4 DSS4 MVS4 MSS4
RATINGS (@ 25˚ C)
APPLICATIONSFEATURES
AGENCY APPROVALS
SRC Devices offers a large selection of molded SIP relays to meet customer applications. The DSS4 was
developed several years ago and continues to be the relay of choice for hook switch applications in modems and
general purpose applications. The SIL4 is the first of a series of new molded products ideally suited for use in high
reliability requirements. Its design centers on a new patent pending process aimed at protecting the hermetically
sealed reed switch. When properly protected, the reed switch outperforms most other electromechanical switching
devices for operating life (at low signal levels), isolation, low resistance and low operating power.
The high performance MVS4 and MSS4 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.
