1. INTRODUCTION
Terminating Head 58246--1 (shown in Figure 1) is
designed to terminate discrete wire in MTA--100 IDC
closed--end receptacle connectors with lock (ramp)
and with lock and polarizing tabs. Slotted contacts for
insulation displacement termination are pre--

inserter and regulates wire inserter travel.
assembled on 2.54--mm [.100--in.] centerlines in each
color--coded housing for a specific wire size.
Feed Slide — automatically positions the connector
after each termination.
The head must be installed in Pistol Grip Manual
Handle Assembly 58074--1 or Pistol Grip Pneumatic
Handle Assembly 58075--1. For head installation and
removal, refer to Instruction Sheet 408--6790 for the
manual handle assembly and 408--6789 for the
pneumatic handle assembly.
Locating Pawl (or Anti--Backup Pawl) — aligns the
connector for insertion, and retains it during
termination.
3. SETUP AND TEST INSPECTION
The adjuster (insertion rod) is preset for wire sizes 28
through 22 AWG. If the wire is being inserted too
deeply or not deeply enough inside the contact, it may
be necessary to adjust the depth of the wire inserter
or, in addition, if the pneumatic handle assembly is
being used, it may be necessary to adjust the air
pressure. Proceed as follows:
For detailed connector description and application
requirements, refer to Application Specification
114--1019.
Read these and all referenced instructions thoroughly
before using the head.
All numerical values in this instruction sheet are
in metric units [with U.S. customary units in
brackets]. Dimensions are in millimeters [and
inches]. Figures are not drawn to scale.
NOTE
3.1. Setup
1. Determine the wire size, and select the
appropriate color--coded connector from Figure 2.

2. Using a small knife, cut off the wire retainers
(strain relief) of the connector. This will provide a
clear view for inspecting the connector for a
properly terminated wire in the contact. See
Figure 3.
For the pneumatic handle assembly, if the wire is
inserted too deeply (more than the required wire
insertion depth), refer to Section 4, WIRE
INSERTION DEPTH ADJUSTMENT. If the wire is
not inserted deeply enough (less than the required
wire insertion depth), increase the air pressure by
69 kPa [10 psi]. Repeat the termination procedure
and check the insertion depth. Continue in this
manner until either the proper insertion depth is
obtained or the air pressure is set to 483 kPa
[70 psi]. If the proper insertion depth is NOT
reached at 483 kPa [70 psi], return the air pressure
to 276 kPa [40 psi], and refer to Section 4.
Wire retainers are removed in a connector for
testing only. DO NOT use such connectors for
production application.
CAUTION
!
3. Make a test termination according to Steps 1
through 5 of Section 5, TERMINATING
PROCEDURE.
6. Inspect the termination according to
Paragraph 3.2.
4. Push the connector out of the right side of the
head.
5. Check that the wire insertion depth is within the
dimension given in Figure 3.
3.2. Termination Inspection (Refer to Figure 3)
Refer to 114 -1019 for detailed explanation of the
termination inspection requirements.
NOTE
To obtain the wire insertion depth, measure from
the front of the contact beam to the center of the
wire as shown in Figure 3 - or - measure from
the front of the contact beam to the back of the
wire and subtract the wire diameter divided by 2.
NOTE
i
i
1 — The required wire insertion depth is within the
dimension given in Figure 3 (refer to Step 5 of
Paragraph 3.1 for measurement).
If it is not, proceed as follows:
For the manual handle assembly, refer to
Section 4, WIRE INSERTION DEPTH
ADJUSTMENT.
2 — The end of the wire extends past the contact
beam by at least 1.52 mm [.060 in.].

5. TERMINATING PROCEDURE (Refer to Figure 5)
3 — The contact beams are NOT deformed. If
damage is apparent, replace the contacts in
accordance with the instructions packaged with the
connector.
There is no wire preparation required.
NOTE
i
4 — The wire insulation is NOT nicked or cut in
any area other than the two contact slots.
1. Insert the connector into the left side of the
head.
5 — The wire extends past the wire retainer (strain
relief) of the connector.
2. Align the contact to be terminated with the wire
inserter of the head (shown in Figure 1). Make sure
that the locating pawl rests between the connector
index ribs.
4. WIRE INSERTION DEPTH ADJUSTMENT (See Figure 4)
1. Remove the head from the handle assembly.
3. Insert an unstripped wire into the funnel area
between the contact and the wire inserter until it
bottoms on the tool base.
2. If the wire is inserted too deeply (more than the
required wire insertion depth), reduce the wire
insertion depth by turning the adjuster 1/6 of a
revolution clockwise. The wire insertion depth will
be reduced by approximately 0.20 mm [.008 in.].
4. Squeeze the cam handle (manual) or depress
the trigger (pneumatic) of the handle assembly,
and hold it until the ratchet releases (manual) or
the wire inserter bottoms (pneumatic).
If the wire is bottomed in the contact slot, this
indicates that the adjuster is set to the maximum
wire insertion depth — DO NOT turn the adjuster
counterclockwise; otherwise damage to the head
may occur.
CAUTION
5. Release the cam handle or trigger. The wire
inserter will retract and the feed slide will
automatically advance the connector to the next
contact position.
!
The locating pawl will move up and down as the
connector is automatically advanced through the
head. However, if movement is obstructed, or if
desired, the locating pawl can be depressed and
the connector moved manually out of the RIGHT
side of the head.
If the wire is not inserted deeply enough (less than
the required wire insertion depth), increase the wire
insertion depth by turning the adjuster 1/6 of a
revolution counterclockwise. The wire insertion
depth will be increased by approximately 0.20 mm
[.008 in.].
NOTE
i
6. Repeat Steps 2 through 5 until all contacts have
been terminated.
When turning the adjuster counterclockwise,
make sure to check the wire insertion depth after
EACH 1/6 revolution. If the adjuster is set past the
maximum setting, damage to the head may
occur.
CAUTION
7. Inspect each termination according to
Paragraph 3.2.

6.3. Inspection
Regular inspections should be performed by quality
control personnel with a record of quality control
inspections remaining with the personnel responsible
for the head. One inspection per month is the
recommended frequency; however, operator training
and skill, amount of use, working conditions, and
established company standards are all factors to be
considered in establishing inspection frequency.
