o
F).
c. Hold the cable assembly approximately 50 mm (2 in.) away from the
heat exhaust area of the heat gun while shrinking the tubing.
d. Continuously rotate the cable assembly around the heat exhaust area
of the heat gun. The entire process should take about four minutes.
e. Inspect the heat-shrink tubing to ensure that there are no voids
where the glue has incompletely melted, noting that voids could
cause a loss of the IP67 rating.
The tubing uses a heat-activated glue to help seal around the cable
and connector body. Some glue may be visible after the heating
process. Caution as this glue is hot.
