Excel Specialty typically produces wire leads and harnesses from #24 through #10 wire. We have done as small as #28. We also process cordage and single conductor wire as large as 500MCM.

Though we process all types of wire, we are proud of our capability and expertise in processing the more difficult high temperature insulated wires such as 200C SRML’(SF), 250C TGGT’s, 450C MGT’s and Teflon insulated wires.

We produce jumpers and leads from 1/2 inch long stripped both ends (depending on wire type) to over hundreds of feet long. Leads can be stripped both ends, terminated both ends or terminated single end. Insulation plugs can be retained (depending on wire and strip length) to help protect wires in shipping.

We typically use TE (Amp) terminals but are also tooled on Molex, Panduit, Hirose, JST and  Arkless. The terminals we are tooled on include spades, spring spades, locking spades, rings, fastons, flag fastons, tabs (male push ons), pins and sockets. Terminals can be preinsulated, uninsulated, post insulated with heat shrink or heat shrink markers, or inserted into housings.

Our harnesses are made and labeled UL and CSA depending upon your needs. We can produce from R&D quantities through runs of 100,000’s.
