MTA Terminating Head 58082-1
01 SEP 11 Rev A
The MTA system uses the Insulation Displacement
Technique which is a method of inserting unstripped
wire into a slotted contact beam to form a reliable
electrical connection between the conductor and
contact.
Index Pawl
Wire Inserter
Feed Slide
After the head is inserted into the pistol grip handle
assembly, it serves as a guide and support for the
connector during termination. Features of the head
(see Figure 1) and their functions are as follows:
Wire Inserter - forces wire into the two slotted beams
of the contact. (Note that it provides support for the
contact beams when applying insertion force on the
wire.)
Head
Adjuster - is a piston for - and regulates travel of - the
wire inserter.
Feed Slide - automatically positions the connector
after each termination.

POSTED CONNECTORS (MTA-156)
Index Pawl - aligns connector for insertion, and retains
it during termination

The adjuster (insertion rod) of the wire inserter is
present for wire sizes 18 through 26 AWG. If the wire
is being inserted too deep or not deep enough inside
the contact, it may be necessary to adjust the depth of
the wire inserter; or, if the pneumatic handle assembly
is being used, it may be necessary to adjust either the
air pressure or the depth of the wire inserter.

according to the wire sizes they accommodate.)
1. INTRODUCTION
This instruction sheet covers the operation and
maintenance of TE Connectivity MTA Terminating
Head 58082-1 for use in Pistol Grip Manual Handle
Assembly 58074-1, or Pistol Grip Pneumatic Handle
Assembly 58075-1. Read these instructions
thoroughly before using the heads. Refer to the
instructions packaged with the pistol grip handle
assembly for head installation and removal.
2. Using a small knife, cut off the wire retainers
(strain relief). This will provide a clear view for
inspecting the connector for a properly terminated
wire in the contact. See Figure 2.
Wire retainers are removed to provide a connector
for testing only. Do NOT use such connectors for

4. Push connector out of right side of head.
5. Inspect termination in accordance with Section 5,
INSPECTION, Steps 1 through 6.
2. DESCRIPTION
This head is designed to terminate wires in MTA
(Mass Termination Assembly) posted connectors with
contacts on 3.96 mm [.156] centers (MTA-156). See
table in Figure 1.
If you determine that the wire insertion depth is
incorrect, proceed to Paragraph 3.3, Wire Insertion
Depth Adjustment.

3.2. For Pistol Grip Pneumatic Handle Assembly
1. Perform the procedure outlined in Paragraph 3.1,
for Pistol Grip Manual Handle Assembly, Steps 1
through 4.
Turn Clockwise to
Reduce Wire
Insertion Depth
2. Inspect termination to ensure that conductor is
terminated past the lead-in transition and is
positioned about halfway into the contact slot. See
Figure 2.
3. Inspect termination to ensure that insulation is
2.03 to 2.54 mm [.080-.100 in.] beyond the front
contact beam.
4. If, upon inspection, it is determined that the wire
is not inserted deep enough, increase the air
pressure by 68.95 kPa [10 psi], and repeat the
termination and inspection procedure. Continue in
this manner until either the proper insertion depth is
obtained, or the air pressure is set to 482.6 kPa
[70 psi]. If the proper insertion depth is not reached
at 482.6 kPa [70 psi], return the air pressure to
275.8 kPa [40 psi] and follow the procedure in
Paragraph 3.3, Wire Insertion Depth Adjustment.

6. TOOL CERTIFICATION
The procedures described in the following text have
been established to ensure quality and reliability of TE
terminating tools. A brief check should be made daily,
and a more detailed inspection should be scheduled
by your quality control group.
6. Release trigger (or cam handle). The inserter will
retract and the feed slide will automatically advance
connector to next contact position.

desirable, the index pawl can be depressed and the
connector moved manually out the RIGHT side of
the head.
i
1. Remove dust, moisture, and other contaminants
with a clean brush, or soft, lint-free cloth. Do NOT
use objects that could damage the tool.
7. Repeat Steps 2 through 6 until all contacts have
been terminated.
2. Make sure all components are in place and
properly secured. (If NOT, return the tool to your
supervisor.)
8. Inspect each termination according to the
procedures in Section 5, INSPECTION.
3. Actuate handle assembly to ensure mechanisms
inside head move smoothly.
5. INSPECTION (Figure 2)
Inspect each termination to ensure the following:
6.2. Quality Control Maintenance
1. Conductor is terminated past the lead-in
Regular inspections should be performed by your
quality control personnel with a record of quality
control inspections remaining with the personnel
responsible for the tool. TE recommends one
inspection a month; however, operation training and
skill, amount of use, ambient working conditions, and
your company’s established standards are all factors
in establishing frequency of inspections.
transition and about halfway in the contact slot.
2. Insulation is 2.03 to 2.54 mm [.080 to .100 in.]
beyond the front contact beam.
3. Wire is NOT bottomed in contact slot.
4. Contact beams are NOT deformed. If damage is
apparent, replace contacts in accordance with the
instructions packaged with the connector.
These inspections should be done in the following
sequence:
5. Insulation of wire is NOT nicked or cut in any area
other than the two wire slots.
1. Remove any accumulated film with a suitable
cleaning agent that will NOT affect plastic material.
6. Wire extends below the strain-relief features of
connector.
