■Applications
Portable terminals, ETC, notebook computers (Bluetooth),
wireless LAN, POS terminals, GPS terminals, PDA, and any
small devices requiring verification of antenna/circuit
performance.
■Overview
Developed for inspection of high frequency
circuits used in portable terminals.Verification of
the circuit performance is
accomplished by simply
inserting the external plug
in the board mounted
receptacle.This action re-directs the circuit from
normal condition to the plug side. Removing the
plug restores circuit to its normal condition.

BPrecautions
1. Care should be taken to avoid accumulation of moisture inside the mounted receptacle after the washing
process.
2. This product is intended to be used for circuit inspection only. Consult factory if any other application is
considered.
3. The corresponding plug should be inserted in direction perpendicular to the switch mounting surface,
within an angle of 2°. The push-in force should be kept within 6-10 N.
4. Do not use hand soldering for mounting on the board. Doing so could result in solder and flux wicking to
the contact portion.
5. When using a heat gun, hotplate, or similar methods, limit the temperature to 260ç applied for 10
seconds max.
6. Consult Hirose if your application, installation methods or end-user environment are different than the
recommended.
