U.FL SeriesꢀUltra Small Surface Mount Coaxial Connectors - 1.9mm or 2.4mm Mated Height
ꢀUsage Precautions
1. Plugs
1) To disconnect connectors, insert the end portion of U.FL-LP-N-2 and U.FL-LP(V)-N-2 under the connector flanges
and pull off vertically, in the direction of the connector mating axis.
2) To mate the connectors, the mating axes of both connectors must be
aligned and the connectors can be mated. The "click" will confirm fully
mated connection.Do not attempt to insert on an extreme angle.

3. Operating environment and storage conditions
The connectors are not designed to operate in the following environments:
• Exposed to a excessive amounts of fine particles and dust
• Regions and places having a high density of sulfur dioxide, hydrogen sulfide, nitrogen dioxide or other corrosive gasses.
• Environments having large rapid variations in temperature.
(1) Operating environment
Store in the Hirose Electric packaging.
(2) Storage conditions -
Receptacle
Temperature: -10 to +40ç, Humidity: 85% max.
Use within 6 months of delivery.
Receptacles for which the storage period has elapsed must be tested for solderability to the PC board mounting surface.
