Usage Precautions
1. Plugs( 1) Mating/ Unmating① To disconnect the connector, insert the extraction tool ( E. FL- LP- N) under the connector flange.
Pull in a perpendicular direction in line with the connector' s mating axis.
When removing the connector directly, hold the connector lid and pull out vertically in relation to the connector matingaxis. Do not unmate the plug by pulling on the cable, this can damage the connector performance.
② When mating, align the mating axes between the receptacle and cable assembly, and insert the cable assembly
downward and perpendicular into the receptacle. Do not insert the cable assembly at a slanted angle.
( 2) Tolerable Load to a Cable After Mating

3N Max.
E. FL-LP-040
5N Max.
E. FL-R-SMT

3N Max.

( 3) Precautions
Do not use excessive prying to mate or un- mate the connectors as it may lead to damage.

3. Operating Environment and Storage Conditions( 1) Operation Environment
This product was designed for use in a normal environment.
Please be advised that using this product in the environments described below may result in discoloration and othertypes of degradation.
・Exposure to excessive amounts of fine particles and dust.
・Regions/ areas with a high concentration of gases like sulfur dioxide, hydrogen sulfide and nitrogen dioxide.
・Areas with drastic temperature changes, such as locations near a heater.
( 2) Storage Conditions
Store this product in Hirose' s packaging or similar conditions.
Temperature : - 10 to + 40℃ Humidity : 85% or less ( recommended storage conditions)
We recommend the product be used within six months from delivery.
Products that have been stored beyond the recommended storage period need to be tested for mounting andsolderability before use.
( 3) Silver Plating Discoloration
Discoloration occurs only on the plating surface. Since the contact portion is wiped, there is no effect on the electricalcontact.

While Taking into Consideration
Specifications mentioned in this catalog are reference values.
When considering to order or use this product, please confirm the Drawing and Product Specifications sheets.
Use an appropriate cable when using the connector in combination with cables.
If considering usage of a non- specified cable, please contact your sales representative.
If assembly process is done by jigs & tools which are not identified by Hirose, assurance will not be given.
If considering usage for below mentioned applications, please contact your sales representative.
In cases where the application will demand a high level of reliability, such as automotive, medical instruments, publicinfrastructure, aerospace/ defense etc. Hirose must review before assurance of reliability can be given.
