FL10010S015L040E21M (item number 1172321) is a Flying Probe for flexible PCB testing without a fixed bed-of-nails fixture. As a Flying Probe, FL10010S015L040E21M can access individual test points without a fixed bed-of-nails fixture, making it suitable for prototypes, small batches and frequently changing layouts. Flying-probe systems move to individual test points and are therefore well suited to prototypes, small production runs and frequently changing layouts. The design combines a pitch of 2.54 mm / 100 mil with tip style 10 (Flexible needle) and a tip diameter of 0.15 mm. Spring force is 40 cN at a nominal travel of 4.3 mm. The continuous-current rating of FL10010S015L040E21M is 5 A.
