The optical transmission

guideline is a supplement of the

German National DIN E 19258

standard draft. On the European

level, prEN 50254 is the draft of

the INTERBUS-S fieldbus.

Package Information

All HFBR-X5X5X series

transmitters and receivers are

housed in a low-cost, dual-in-line

package that is made of high

strength, heat resistant,

chemically resistant and UL 94

V-O (UL file # E121562) flame

retardant plastic. The

transmitters are easily identified

by the light grey colored

connector port. The receivers are

easily identified by the dark grey

colored connector port. The

package is designed for auto-

insertion and wave soldering so it

is ideal for high volume production

applications.

Handling and Design Information

When soldering, it is advisable to

leave the protective cap on the unit

to keep the optics clean. Good

system performance requires clean

port optics and cable ferrules to

avoid obstructing the optical path.

Clean compressed air often is

sufficient to remove particles of

dirt; methanol on a cotton swab

also works well.

Recommended Chemicals for

Cleaning/Degreasing X5X5X Products

Alcohols: methyl, isopropyl,

isobutyl.

Aliphatics: hexane, heptane.

Other: soap solution, naphtha.

Do not use partially halogenated

hydrocarbons such as

1,1,1 trichloroethane, ketones

such as MEK, acetone,

chloroform, ethyl acetate,

methylene dichloride, phenol,

methylene chloride or

N-methylpyrolldone. Also, Avago

does not recommend the use of

cleaners that use halogenated

hydrocarbons because of their

potential environmental harm.

CAUTION: The small junction size inherent in the design of these components increases the

components’ susceptibility to damage from electrostatic discharge (ESD). It is advised that normal

static precautions be taken in handling and assembly of these components to prevent damage and/or

degradation which may be induced by ESD.
