RF Coaxial Switches (DC to 15 GHz)
HCS2 Series
sFeatures
1.High Performance and High Reliability
These switches are of the SPDT fail-safe type and
have been designed for wide frequency bandwidth,
contact voltage strength, power saving, and vibration
resistance.
2.SMA Connections
SMA type coupling (Hirose Electric HRM Series) has
been used.
3.Environmentally Rugged
A wide variety of tests including temperature and
humidity cycles, high temperature power, low
temperature power, humidity,vibration, and shock have
been conducted and good results were obtained for all.

The temperature resistance cycle, humidity resistance, and shock resistance tests are verification tests of part deterioration and
looseness, not tests to be conducted at time of switching or when conducting.

Precautions
q
The HCS2 Series is of the fail safe type and designed to make contact by spring force when the drive voltage is not applied. The
application of vibrations or shocks in excess of the spring limit may cause resonance of the spring which results in a loss of contact
stability and intermittent contact.
q
The construction does not prevent the effects of humidity, pressure, or the atmosphere (i.e., gases, oils, and liquids). (Gases, depending
on type, may penetrate the spring material inside. The penetration of gases, oils, or liquids that form a film on the contacts may causes
changes of the insulation or may cause the contacts to cease to conduct.)
q
This product is not magnetically shielded and as such the attention must be paid to the following points.
(1) The plate used to mount this product should be made of non-magnetic material. (Aluminum plate is preferable.)
(2) Avoid the use of magnetic material and anything that may produce a magnetic field such as a magnet in the proximity of the switches
(roughly a 15 mm square).
