Package Information
The transmitter and receiver are housed in a dual-in-line
package made of high strength, heat resistant, chem-
ically resistant, and UL V-0 ame retardant plastic. The
package is auto-insertable and wave solderable for high
volume production applications.
Note: The “T” in the product numbers indicates a Threaded
ST connector (panel mountable), for both transmitter
and receiver.
Handling and Design Information
When soldering, it is advisable to leave the protective cap
on the unit to keep the optics clean. Good system per-
formance requires clean port optics and cable ferrules
to avoid obstructing the optical path. Clean com pressed
air is often sucient to remove particles of dirt; methanol
on a cotton swab also works well.
Recommended Chemicals for Cleaning/Degreasing
Alcohols (methyl, isopropyl, isobutyl)
Aliphatics (hexane, heptane)
Other (soap solution, naphtha)
Do not use partially halogenated hydrocarbons (such as
1.1.1 tri chloroethane), 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 halo-
genated hydrocarbons because of their potential envi-
ronmental harm.

Panel Mounting Hardware
The HFBR-4411Z kit consists of 100 nuts and 100 washers
with dimensions as shown in Figure 1. These kits are
available from Avago or any authorized distrib utor. Any
standard size nut and washer will work, provided the
total thickness of the wall, nut, and washer does not
exceed 0.2 inch (5.1 mm).
When preparing the chassis wall for panel mounting, use
the mounting template in Figure 2. When tightening the
nut, torque should not exceed 0.8 N-m (8.0 in-lb).
