3.4 Mounting

The 9522B LBT incorporates (6) mounting holes on its bottom surface that can aid in its mounting. See
Figure 3 for locations of these features. It is recommended that a thread-forming screw be used to mount
the 9522B LBT via these features. Particularly, a Textron Camcar® Taptite® II Thread-Rolling Fastener of
M3.5x0.6 thread type is recommended. This fastener has a 15IP Torx Plus® pan head and is available in
lengths of 6, 8, 12, 16, and 20 mm as part number 3BE-P802-00, 3BE-P803-00, 3BE-P8185-00, 3BE-
P804-00, 3BEP8186-00, and 3BE-P8187-00 respectively. Length should be chosen to ensure that
penetration into the 9522B LBT housing does not exceed 11 mm. If a 6-32 thread type is desired, a
Textron Camcar® Taptite® II Thread-Rolling Fastener with a 15IP Torx Plus® pan head is available in
lengths of 1/4, 5/16, 3/8, 1/2, 5/8, 3/4, and 1 inch as part number 3BE-P814-00, 3BE-P8123-00, 3BE-
P815-00, 3BE-P816-00, 3BE-P8124-00, 3BE-P817-00, and 3BE-P818-00 respectively. A 10IP Torx Plus®
flat head version is also available in a single length of 1/2 inch as part number 3BE-P801-00. Another 6-32
thread type option is to insert a helical coil insert with a 6-32 internal thread into these features thus
accommodating 6-32 threaded fasteners as mounting hardware for the 9522B LBT. National Aerospace
Standard NASM122238 serves as a technical reference for the recommended helical coil insert.

3.5 Mounting in Harsh Environments

If the 9522B LBT is to be used in a harsh environment with exposure to high humidity, water or dust, the
LBT must be installed in the correct orientation, with all connectors facing downwards.
