FSK-11.1A-20 is a flexible jumper wire assembly manufactured by TE Connectivity (Buchanan brand) designed for electronic interconnection and signal routing in automotive and general applications. The product features multiple conductor pitch options 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, and supports insulation lengths from 0.50 to 30.0 inches in 0.10-inch increments plus 0.25 and 0.75-inch options. Available insulation materials include Nomex, Polyester, Teflon, and Kapton, with standard bends (E, F, G, H, J, K, L) and configurable pin arrangements for both straight and staggered pin orientations. The jumper assembly maintains a minimum bend radius of 3.18 mm across all conductor pitches and operates over a temperature range suitable for soldering and field applications, making it ideal for automotive wiring harnesses, circuit board interconnections, and flexible routing in space-constrained environments.
