1. INTRODUCTION
This instruction sheet covers the assembly of the
AMPLIMITE Connector Cassette and Holder Kits
shown in Figure 1. The kits are used to construct
cassette and holder units for various applications.
Read these instructions thoroughly before starting
assembly.
NOTE
Dimensions on this instruction sheet are in
inches.
The cassette kits consist of a top cover with locking
latches, a bottom cover with locking tabs, a
write/protect switch, a 33–position receptacle contact
connector, and a face plate. These items, when
assembled, house the customer–supplied printed
circuit board memory assembly. The face plate
features three polarizing slots which provide keying.
The keying feature eliminates insertion of an incorrect
cassette into a holder. The write/protect switch is
used to select a program (write) or protect (read only)
access to a programmed memory. See Figure 1 and
Figure 3.
The holder kits consists of a main body, a
panel–mount cover, and a 33–position pin contact
connnector. The panel–mount cover features three
polarizing guides which provide keying and thereby
prevent insertion of an undesired cassette. The
panel–mount cover also has provisions for
light–emitting diodes (LEDs) which are used to
indicate a functioning mode.
Reasons for revison are contained in Section 5,
REVISION SUMMARY.
2. DESCRIPTION
These units provide an interface between
magnetic–bubble memories or semiconductor read
only memories (ROM) and computer–controlled
equipment. The cassettes are available in kits of
standard and long sizes. The kits (cassettes and
holders) are capable of continuous mating and
unmating without loss of mechanical or electrical
integrity. Significant features of the assembled
cassette and holder units include ease of assembly,
quick mating/unmating capability, program protection,
and program–mode indication.
3. ASSEMBLY PROCEDURE
The two connectors in the units are designed to be
installed on a .062–in.–thick pc boards. The size of
cassette pc board is regulated by the interior
dimensions of the cassette. The only limitation placed
on the holder pc board is in the location of the
connector relative to the edge of the pc board.

3.1. Cassette Assembly
(Figure 2 and Figure 3)
1. Determine whether a standard or long unit will
be used. Then, using the dimensions shown in
Figure 2, select a pc board for the cassette. Make
the latch and beveled corner cuts on the pc board
edges as shown.
2. Determine the pin pattern for the memory
components. Make the hole layout for the memory
components and the cassette connector.
3. Install and solder the connector and memory
components in the pc board.
4. Determine the number of polarizing slots to be
open and select the appropriate cassette and
holder kits with the desired keying configuration.
NOTE
If a write/protect device is to be installed, place
reflective tape (customer–supplied) on the switch
pad as indicated in Figure 3.

6. Place the pc board and it’s attached
components into the bottom of the cover as
indicated in Figure 3. Make sure the face plate and
bottom cover polarizing slots are properly aligned.

7. Align the top cover with the bottom cover and
insert the latches until they are engaged with the
tabs
8. If the covers require separation for repair of
internal components, obtain the Release Tool
91251–1 and refer to 408–6809 for the cover
separation procedure.
408–6662
4. With the components firmly seated on the pc
board, solder the pins in place.
5. Align the locking latches of the body with the
locking tabs on the connector and then slide the
body onto the connector until the latches snap over
the tabs.
6. Place the panel–mount cover on the body and
position the panel over the holder. Secure the
panel with four No. 4–40 screws.
This completes the assembly of the holder. It may be
disassembled by removing the four No. 4–40 screws,
removing the panel mount cover, and disengaging the
body locking latches from the locking tabs.
3.2. Holder Assembly
(Figure 4 and Figure 5)
1. Determine the location for the holder. Then
make a hole layout on the pc board using the
dimensions shown in Figure 4.
NOTE
If applicable, make holes for the sensor and the
LED.
2. Orient the pin connector so that the pins and
mounting holes are aligned with the holes in the pc
board and insert the pins into the pc board.
NOTE
The holder may be secured to the pc board with
rivets, screws, bolts and nuts, or other suitable
hardware.Rivets may be installed before
soldering, but all other types of hardware should
be installed after soldering.
4. MATING AND UNMATING
(Figure 6)
If a sensor was installed, determine whether the
cassette is to be in the write (program) or in the
protect mode, and place the sliding write/protect
switch in the appropriate position.
To insert the cassette, orient it so that the polarizing
slots align with the polarizing guides, and then insert it
straight into the holder until it bottoms.
3. If applicable, insert LED and sensor pins.
