FSN-11A-12 is a flexible jumper wire assembly manufactured by TE Connectivity/Buchanan Brand, designed for custom interconnect applications with multiple configuration options. The product features selectable conductor pitches ranging from 1.00 mm (0.039 in) to 5.08 mm (0.200 in), with wire gauges from AWG 28 to AWG 24 depending on pitch selection. Available insulation materials include Nomex, Polyester, Teflon, and Kapton, with standard jumper lengths from 11.92 mm to 152.40 mm (0.500 to 6.000 in) in 2.50 mm (0.10 in) increments, plus 6.35 mm (0.25 in) and 19.05 mm (0.75 in) options. Pin configurations support straight, right-angle, and staggered arrangements with multiple bend options (E through L bends available depending on pitch), and special pin lengths are available via suffix codes (V1 through V11). The minimum bend radius is 3.18 mm (0.125 in) for all conductor pitches, and the product is suitable for automotive and general interconnect applications requiring flexible, customizable wiring solutions.
