Interface Coaxial Switches
MS-145 Series
■Features
01. Space saving
External dimensions are 7mm x 4.6mm.
Saves installation space.
02. Low profile
Low protrusion of only 6mm above the mounting surface
(receptacle).
03. Light weight
Weight is only 0.18g.
04. Durability
High durability(mating/unmating) of 10 000 cycles.
05. Automatic mounting
Receptacle designed for placement on board with automated
equipment.
06. Frequency range
Can be used from DC to 2.5 GHz and with GSM, PCS, cdma-
One,W-CDMA, etc.
07. Plugs
Wide variety of mating heights are available.
08. Solder wicking
Receptacle terminations are designed to prevent solder wicking
into the critical contact areas.
09. Self alignment of mating parts
Inducement to floating is ±0.5mm.
■Overview and applications
Designed primarily as interface coaxial switch for
a mobile phones, they are also used in variety of
other applications requiring redirecting of signals
when mating with corresponding plug.
The mating action redirects the signals from the
receptacle side to the plug side.

BPrecautions
1. Please select plugs according to the following applications.
2. Applicable cable for plugs: 1.5D-HQEW or 1.5D-QEW (manufactured by Fujikura Ltd.).
3. No cleaning is needed after soldering or cable termination.
4. Please design avoiding holes so that force is not applied to this product from the case
when dropped in the board mounted condition.
5. When mounted as the RF interface of a Mobile Phone, please consider using a rubber
cap when the plug is not engaged to prevent dust from entering.
