The Centi Line - .075" Contact Spacing
Standard Data
The Cannon Centi connectors are especially
suitable for commercial applications such as
computers, instrumentation, communications
and audio equipment. They are available in D
subminiature size metal shell rectangular, plas-
tic shell rectangular and strip configurations.
All Centi connectors use the reliable twist pin
contact design in a 5 amp version terminated
on .075 (1.91) and .100 (2.54) centers. The
Centi contact is crimp removable, connectors
are available for customer assembly. Standard
crimp and assembly tools are available.
The twist pin contact is recessed within the
insulator housing while the rugged cylindrical
socket is exposed. When the connector halves
are mated, the chamfered sockets guide the
pins into positive alignment. The CentipinTM
contact, now under compression, forms a
multi-point contact with the CentisocketTM to
provide a high degree of reliability.
•Contact rating: 5 amps max, except BR
Series (2 amps max.)
•Minimum contact centers: 0.075 (1.91).
•Wiresizes: #22 thru #26 AWG, stranded or
solid.
•Contact termination: Multiple indent crimp.
•Contact retention: Crimp snap-in/removable.
•Contact materials and finish: Copper alloy,
gold- plated per ASTM B488, Type II, Code
C, Class 1.25.
•Mating/unmating force: 12 oz. per contact,
max.

Double Density D - .075" Contact Spacing 2D
The Double Density D is a rectangular connector in
the popular D Subminiature shell configuration
featuring double the contact density in the same
insert area. The Double Density D connector can
thus accommodate up to 100 contacts instead of 50.
This double contact density is achieved by using
field-proven, highly reliable CentipinTM/CentisocketTM
contacts on .075 (1.91) centers, in the positive con-
tact alignment design. In this design contact
positions are reversed; the flexible CentipinTM
contacts are recessed in the insulator and the more
rugged CentisocketTMcontacts are exposed. This
reversal of positions, and the chamfered-entry of the
sockets, assures positive mating even under severe
misalignment conditions. The contacts are retained
in the monobloc insulator by a resilient internal
shoulder that snaps into a locking groove in the con-
tact. The chamfered front of the contact will not
damage the internal shoulder in the insulator.
Contacts are crimp removable type.
The Double Density D connector is available in the
five popular shell and insert sizes accommodating up
to100 contacts. These connectors mate exclusively
with other Double Density D connectors. A wide
range of accessories can be used, including junction
shells, potting cups, switching shells, guide pin
plates, and dust caps.

2D/CTA CENTI-LOCTM Connectors Assembly Instructions

www.ittcannon.com
The Double Density D/CTA CENTI-LOC Connectors
are highly reliable and simple connectors to use.
There are a few helpful suggestions that will assure
complete satisfaction when followed:
1. The following instructions should be followed.
2. The proper crimp tool and locator (if required)
must be used. These tools have been designed
for use with this product. Substitutions of crimp-
ing equipment may result in connector failure at
the assembly operation.
3. After crimping a contact to a lead it is of vital
importance that the proper tool be used to assure
seating the contact in the insulator in the proper
position. Any substitution of insertion tools may
result in over or under insertion of the contact
which may damage the retention system of the
insulator.
4. The female (socket) side of the connector has
been designed with a controlled float to allow for
ease of mating. To avoid reducing this float or
causing a splaying of the contacts, any unneces-
sary strain caused by clamping the leads too
close to the rear of the connector should be
avoided.
Use of recommended tooling together with proper
assembly techniques will pay dividends in reliability
and reduced costs.
2D Assembly Instructions
Cut the wires to length required and strip .100" of
insulation from the end to be crimped. Check for
cut or broken wires and frayed insulation.
Using the proper crimp tool and locator, insert the
contact into the locator. Insert the stripped end of the
wire into the contact crimp pot, and crimp the contact to
the wire. Squeeze the handles firmly to insure a proper
crimp (tool will not release if crimping is incomplete).
NOTE: Contact stop must be changed in tool locator
when crimping pin and socket contacts.
1. Placethe properinsertion tip in the
insertion/-extraction handle and put the tip over the
wire as shown. The tool tip will butt up against the
crimppot.Connectormust be firmlysupported
duringbothinsertion andextractionoperations.
2. Using a firm, steady pressure, push the contact into
the cavity until the resilient internal shoulder in the
insulator snaps into the locking groove in the contact.
The shoulder of the tool tip bottoms against the rear
of the insulator, preventing over-insertion. Repeat for
balance of contacts.
1. For contact extraction, remove the insertion tool
tip and replace it with the proper extraction tool tip.
(The socket tip will fit into the socket, and the pin
tip will slide over the pin bundle). Insert the tool tip
into the contact cavity: (the pin tip will butt up
against the shoulder of the pin contact, and the
socket tip will bottom out in the socket contact.)
2. Apply a firm, steady pressure until the contact is
released from the internal shoulder in the insulator. The
shoulder of the tool tip bottom against the insulator
face to prevent damage to the internal shoulder.
Remove the tool tip and pull the contact from the rear
of the connector. Repeat for the balance of contacts to
be removed.

INSERTION
Guide Posts
Polarizing Posts
1. Place the connector into the slot in the assembly block
with the arrows on the insulator pointing downward. The
connector will bottom against the internal shoulder in the
groove in the assembly block. Start contact insertion by
placing the crimped contact in the cavity by hard.
3. With firm steady pressure, push the contact into the
cavity until the resilient internal shoulder snaps into the
locking groove in the contact. To prevent over insertion,
the tool tip bottoms against the rear of the insulator.
4. The guide post and polarizing posts are inserted in teh
same manner as the contacts. The guide posts are inserted
into the socket insulator, and the polarizing posts are
inserted into the pin insulartor. The corresponding contact
in the mating insulator must be removed for each.
2. Position the insertion tool tip on the rear of contact as
shown. The insulation must be pulled back from the crimp
pot approximately 1/32" to allow the tool tip to butt
against the contact crimp pot.
EXTRACTION
1. To extract the contacts, place the conector face up in
the assembly block so that the contact to be extracted is
in the end of the block that has a fully slotted opening.
2. The pin extraction tool tip is tubular, slides over the pin
bundle and butts against the front shoulder of the pin. The
socket extraction tool is a solid rod that fits into the socket
contact, the external shoulder butts against the contact
socket shoulder.
3. Insert the extraction tool into the cavity and apply firm
pressure until the contact is pushed thru the rear of the
connector.
4. Lift the insulator from the groove and pull the contact
out. Repeat for balance of contacts to be removed.
