Frequently Asked Questions
How many pins does the TFM-126-22-SM-D provide, and how are they arranged across its dual-row layout?
The TFM-126-22-SM-D provides 52 pins total, with 26 pins per row across two parallel rows at a 0.050-inch pitch. This dual-row arrangement enables high-signal-density board-to-board and mezzanine connections in defense, aerospace, and high-reliability computing systems where large numbers of signals must be routed within a minimal PCB footprint.
How does the Tiger Eye contact system in the TFM-126-22-SM-D maintain reliable connections across demanding mating cycles?
The Tiger Eye contacts in the TFM-126-22-SM-D apply high-normal-force wiping action across all 52 pins with every mating cycle, creating gas-tight connections that resist oxidation and maintain low contact resistance over thousands of insertions. This makes it a preferred connector for avionics, radar systems, and test equipment requiring long-term 0.050-inch pitch interconnect reliability under mechanical vibration.
For which high-reliability defense and aerospace applications is the TFM-126-22-SM-D dual-row SMT design best suited?
The TFM-126-22-SM-D is well-suited for avionics flight computers, defense radar assemblies, and precision test and measurement boards requiring 52-pin dual-row mezzanine connectivity in compact SMT form. Its surface mount construction supports reflow soldering for tight placement accuracy, and the 0.050-inch pitch configuration performs reliably from -55°C to +125°C in demanding aerospace and industrial environments.
When does a designer select the TFM-126-22-SM-D over wider-pitch dual-row connectors for a mezzanine interconnect design?
A designer chooses the TFM-126-22-SM-D when routing 52 pins between two boards demands a 0.050-inch pitch footprint that is approximately half the PCB length of equivalent 0.100-inch pitch dual-row connectors. The Tiger Eye high-reliability contact system ensures this dense pitch maintains low contact resistance and signal integrity from -55°C to +125°C in defense and aerospace mezzanine applications where PCB real estate is at a premium.
