Package and Handling
Information
Package Information
All HFBR-0400 Series
transmitters and receivers are
housed in a low-cost, dual-inline
package that is made of high
strength, heat resistant, chem-
ically resistant, and UL 94V-O
flame retardant ULTEM
(plastic
(UL File #E121562). The
transmitters are easily identified
by the light grey color connector
port. The receivers are easily
identified by the dark grey color
connector port. (Black color for
conductive port.) The package is
designed for auto-insertion and
wave soldering so it is ideal for
high volume production
applications.
Handling and Design
Information
Each part comes with a protective
port cap or plug covering the
optics. These caps/plugs will vary
by port style. When soldering, it
is advisable to leave the protec-
tive 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
HFBR-0400 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, HP
does not recommend the use of
cleaners that use halogenated
hydrocarbons because of their
potential environmental harm.
