Frequently Asked Questions
What makes the Tiger Eye contact design in TFM-135-22-L-D superior to standard socket strips?
The Tiger Eye contact in TFM-135-22-L-D generates higher normal force than standard contacts, resulting in lower and more stable contact resistance across the 0.050-inch (1.27 mm) pitch dual-row interface. This design is engineered to maintain reliable electrical connection even after many hundreds of mating cycles in vibration-prone environments.
What contact finish does the TFM-135-22-L-D use, and how does it affect long-term reliability?
The TFM-135-22-L-D uses 15 microinches of gold over 50 microinches of nickel on its mating contacts, and tin with a nickel barrier on the termination side. This gold-over-nickel finish provides low contact resistance, excellent corrosion resistance, and reliable performance over extended operational life in telecom and industrial applications.
Which board-to-board mating scenarios benefit most from the shrouded ELP feature of the TFM-135-22-L-D?
The shrouded ELP (Extended Latch Post) feature on the TFM-135-22-L-D prevents accidental mis-mating across the dual-row 0.050-inch pitch interface by providing mechanical polarization. This is particularly valuable in field-replaceable mezzanine card designs, defense electronics, and industrial modules where incorrect insertion could damage a 70-position array of phosphor bronze contacts.
How does the TFM-135-22-L-D compare with non-Tiger Eye SAMTEC terminal strips for procurement and lifecycle planning?
The TFM-135-22-L-D is an active RoHS-compliant product in SAMTEC's TFM Tiger Eye series, featuring lead-free (Pb-free) terminations. Compared to standard SFM or TSM series strips without the Tiger Eye feature, TFM parts command a slightly higher price but offer a significantly longer mechanical life cycle suited for applications requiring 1,000 or more mating cycles at 1.27 mm pitch.
