Available in three pitches — 0.80 mm, 1.27 mm and 2.00 mm – Samtec’s Tiger Eye™ interconnect systems are designed for micro rugged, high-reliability, high-cycle applications. Tiger Eye is a multi-finger, heat-treated, Beryllium Copper (BeCu) contact designed for rugged environments. The superior spring properties of Beryllium Copper make it ideal for high mating cycle applications. Once formed and hardened, BeCu will retain its shape under a wide variety of conditions.
The contact mating surface is on the flat, smooth side of each finger. Smooth surfaces allow more mating cycles because it does not stress the plating. This provides lower contact resistance and longer plating life. A micro slot on the tail allows solder paste to penetrate the slot, wetting a larger surface area on the lead, providing greater solder joint strength. Connectors with micro tail slots tend to adhere to the wet solder paste prior to reflow better than flat leads.
Tiger Eye is available in a variety of connector interfaces, including two-piece board-to-board, discrete wire systems, and IDC cable assemblies. The popular SFM, TFM are a 1.27 mm pitch mated socket and terminal set available in vertical, right angle, and horizontal orientations. SFM, TFM are polarized to ensure proper mating, they are available with optional friction locks to increase unmating force, in a variety of stack heights, and in both through-hole and SMT terminations.
The FFSD Series is a 1.27 mm pitch Tiger Eye IDC cable assembly. FFSD is low profile (.200”), available with ejector or shrouded headers, polarization notches, and numerous wiring and termination options. IDC assemblies are also available on 2.00 mm pitch.
Tiger Eye is also available in rugged discrete wire cable assemblies; most are shrouded, polarized, and keyed; they are available with metal latch and screw down options; as components or complete assemblies; and they are available with PVC or Teflon® cable, in 28 and 30 AWG.
