4.3.2 Antenna Connector
The 9522A provides a single 50
, TNC type antenna connector both
transmit and receive.
4.3.3 SIM Chip Reader
An integrated SIM chip reader is provided on the 9522A. This connector
allows installation of the chip form of the SIM beneath a cover plate on
the 9522A housing.
4.4 Mounting
The 9522A 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 9522A
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 9522A 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
9522A. National Aerospace Standard NASM122238 serves as a
technical reference for the recommended helical coil insert.
