Optional selective electroless nickel
plating on shield termination area and
polysulfide dielectric barrier prevents
galvanic mismatch between nickel-
coated braid shield and backshell.
SHRINK BOOT
Optional heatshrink boot provides cable
strain relief and environmental protection.
Code T, T1: Type 1 high-performance
semi-rigid elastomer resists fuels and
oils. Operating temperature range -75
to +150 °C. Code T1 adds W1 hot melt
adhesive precoat (-55 to +125 °C).
Code H, H1: Type 2 halogen-free
polyolefin meets low smoke and toxicity
requirements of shipboard, transit and
aircraft systems. Operating temperature
range -40 to +130 °C. Code H1 adds W1 hot
melt adhesive precoat (-55 to +125 °C).
