• Our
HM and HM-L series immersion resistant shield terminators provide a rugged and
environmentally sealed soldered connection which is completely insulated, encapsulated and
strain-relieved. They are normally supplied with either pre-installed ground leads (HM-L
Series) or no leads (HM Series). Both series of parts offer installation which is rapid,
convenient and easy.
• In addition to meeting
MIL-Spec performance requirements of MIL-S-83519, the H-M and H-ML series shield
terminators provide the added benefits of increased operating temperatures, choice of
color coded ground leads and different ground lead types, including metal braid.
• These Special
Termination Sleeve (STS) devices are offered with a choice of pre-installed lead wire
insulations. They are available with either irradiated fluoropolymer jacketed leads
(MIL-W-22759/32) or *Kapton jacketed leads (MIL-W-81381/21). |
• The outer
heat-shrinkable jacket is a precision engineered polyvinylidene fluoride sleeve containing
exactly the right amount of pre-fluxed solder to provide reliable connections time after
time. Thermoplastic sealing rings ate each end of the sleeve melt and flow during the
shrinking process to strain-relieve and form an environmental seal that meets MIL-Spec
criteria. The solder preform is coated with a special thermochromic indicator which
changes color when the proper amount of heat has been applied. This serves to assist the
operator during installation and inspection. All parts also have a permanent
identification number marked on the exterior of the *Kynar sleeves.
The use of HM-L series parts with pre-installed ground leads means there is only one part
to handle eliminating the need to spend time on positioning components. this ease of
handling can reduce labor costs, give higher production yields, and eliminate the need to
inventory wire or braid.

SIZE SELECTION (to determine which size terminator best meets your
requirements:)
1. Determine cable dimensions, either "center strip" or "end
strip", using the diagrams at the left of the table.
2. Refer to the cable dimension table below.

INSTALLATION INSTRUCTIONS
• Preparation of ground lead (if
required)
Strip insulation as shown
• Preparation of shielded cable
Strip insulation as shown
TERMINATION ASSEMBLY
• Assemble components as shown.
• Make sure no loose strands are present.
• Ground lead may be front or rear entry.
HEATING OF ASSEMBLY
1.) Use one of your preferred heating tools
with appropriate reflector.
2.)Direct heat, either infrared or convection, at solder preform until substrates have wet
and a proper fillet is obtained.
3.)If necessary, apply heat to remainder of device to assure proper installation. |
