1. INTRODUCTION
This specification covers the requirements for application of STRATO-THERM terminals, splices, and spare
wire caps for high temperature applications. There are two types of these terminals, splices, and spare wire
caps. One type is insulated, which consist of PIDG* (pre-insulated diamond grip) ring tongue terminals, splices,
and spare wire caps insulated with polytetrafluoroethylene (PTFE), post-insulated, or pre-insulated ; and the
other type is uninsulated, which consist of DIAMOND GRIP* (insulation support) ring tongue terminals, spade
tongue terminals, and splices with SOLISTRAND* (non-insulation support). The uninsulated are available in
heat resistant and high temperature. The terminals, splices, and spare wire caps accept solid or stranded wire
for single applications.
The pre-insulated terminals, splices, and spare wire caps are designed for reliable performance at maximum
temperatures of 288°C [550°F] and at 260°C [500°F] for silver-plated post-insulated terminals and splices. The
uninsulated heat resistant terminals and splices operate at maximum temperature of 343°C [650°F], and at
649°C [1200°F] for high temperature terminals and splices.
The terminals and splices are color-coded to provide a visual reference applicable to the wire size range suitable
for the terminal or splice. In addition, terminals are marked on the tongue with the wire size range. The
serrations or dimples inside the wire barrel provide maximum contact and tensile strength after crimping. The
terminals are suitable for mounting and accept stud sizes M2.5 [4] through M8 [.375] (inside diameter range of
2.95 through 9.80 [.116 through .386]). The terminals, splices, and spare wire caps are available in loose-piece
for terminating with manual and pneumatically-powered hand-held tools, and in tape-mounted form for
terminating with semi-automatic hand-held tools and electrically-powered machines.
When corresponding with personnel, use the terminology provided in this specification to facilitate your inquiries
for information. Basic terms and features of this product are provided in Figure 1.

3. REQUIREMENTS
3.1. Special Characteristics
PIDG IR terminals prevent insulation of thin-wall insulated wire from entering the wire barrel during crimping.
3.2. Material
A. Insulated
These terminals, splices, and spare wire caps consist of precision formed metal wire barrel and support
sleeve (except spare wire caps) insulated with PTFE.
PIDG Terminals and Pre-Insulated Terminals and Splices
-- The body is made of copper and plated with
nickel or gold over nickel. The metallic sleeve is made of copper and plated with nickel.
Post-Insulated Terminals and Splices
-- The body is made of copper and plated with gold over nickel, sil-
ver, or nickel. The ring is made of aluminum or copper and plated with nickel. The bushing is made of PTFE
insulation.
B. Uninsulated
These terminals and splices consist of precision formed metal wire barrel with or without a support sleeve.
SOLISTRAND Terminals and Splices
-- The heat resistant body is made of copper and plated with nickel.
The high temperature body is made of nickel.
DIAMOND GRIP Terminals and Splices
-- The heat resistant body is made of copper and plated with
nickel. The high temperature body is made of nickel, alumel, or chromel. The metallic sleeve is made of
nickel silver.
3.3. Storage
A. Shelf Life
The product should remain in the shipping containers until ready for use to prevent deformation to the
terminals, splices, or spare wire caps. The product should be used on a first in, first out basis to avoid
storage contamination that could adversely affect signal transmissions.
B. Ultraviolet Light
Prolonged exposure to ultraviolet light may deteriorate the chemical composition used in the product insula-
tion material.
C. Reeled Product
When using tape-mounted reeled product, care must be taken to prevent stretching, sagging, or other distor-
tion that would prevent smooth feeding of the tape through automatic machine feed mechanisms. Store coil
wound reels horizontally and traverse wound reels vertically.
3.4. Wire Selection and Preparation
The terminals, splices, and spare wire caps accept copper wire sizes 26 through 1/0 AWG (238 through 119,500
circular mil area) with an insulation diameter range of 1.17 through 7.87 [.046 through .310].
PIDG terminals and splices must be used with stranded wire; and PIDG insulation restricting terminals, and
post-insulated and uninsulated terminals and splices with solid or stranded wire. The splices can accommodate
different wire combinations. Proper strip length is necessary to properly insert the wire into the terminal or splice.
The wire must be stripped to the dimensions provided in the instructional material supplied with the product or
application tooling.
CAUTION
Reasonable care must be taken not to nick, scrape, or cut any strands during the stripping operation.
!
The spare wire caps must be used with unstripped PTFE insulated stranded wire with insulation diameter range
of 0.91 through 3.50 [.036 through .138].

3.5. Wire Placement
The solid wire conductor or stranded wire conductors must be inside the terminal, splice, or spare wire cap wire
barrel. No strands can be folded back over the wire insulation. The conductor end(s) must be flush with, or
extend slightly beyond, the end of the wire barrel; or, for splices with a wire stop in the center of the splice, the
conductor end(s) must butt against the wire stop. The wire insulation must be inside the insulation of the
product, but must not enter the wire barrel, to provide strain relief for the wire.
3.6. Crimp Requirements
The terminal, splice, or spare wire cap must be crimped to the wire according to instructions packaged with
applicable tooling.
CAUTION
Wire insulation must NOT be cut or broken during the crimping operation. Reasonable care must be taken to provide
undamaged wire terminations.
!
A. Wire Barrel Crimp
The crimp applied to the wire barrel portion of the terminal, splice, or spare wire cap is the most compressed
area and is most critical in ensuring optimum electrical and mechanical performance of the crimped product.
The crimped area must be symmetrical on both sides of the wire barrel. The crimp may be off center on the
wire barrel but not off the end of the wire barrel. See Figure 2.
NOTE
The resilience of the product insulation prevents accurate direct measurement of crimp height. Tooling used to crimp
product must be dimensionally correct to ensure quality crimp configurations.
i
B. Crimp Dot and Hashmark Code
Some tools with multiple crimping chambers will emboss a crimp dot code or hashmark code onto the prod-
uct insulation when crimped. The dot or hashmark code must be fully formed on the insulation to indicate
that the correct product and tooling combination was used. The crimp dot or hashmark code must corre-
spond with the wire size marking on the tooling.
NOTE
The hashmark code should appear on the bottom (side opposite the crimp indents) for high temperature and heat-
resistant terminals and splices.
i
C. Wire Conductor and Insulation Location
The wire insulation must be inside, and in firm contact with, the insulation barrel of the product. The wire
insulation must not enter the wire barrel. The conductor end(s) must be flush with, or extend slightly beyond,
the end of the wire barrel; or, for splices with a wire stop in the center of the splice, the conductor end(s) may
butt against the wire stop. See Figure 2.
D. Product Insulation
The terminal, splice, or spare wire cap insulation must not be deformed, cut, or show uneven stress marks.
Some insulation flash or extruded insulation is normal. Holes and thin spots in the insulation provides evi-
dence of either improper crimping or defective tooling.
E. Bellmouths
The rear bellmouth length must be within 0.51 to 1.27 [.020 to .050], and the front bellmouth must not
exceed 0.51 [.020]. Refer to Figure 2.
F. Sleeve, Ring, and Bushing Position (Post-Insulated Terminal and Splice Only)
After crimping post-insulated terminals or splices, rings, bushings, and a sleeve must be assembled onto the
terminal or splice. The sleeve must be centered over the crimped terminal wire barrel or crimped splice. The
sleeve must extend from the ring and the bushing must extend from the sleeve to the dimensions shown in
Figure 2.
