What are the key features of TFC-126-02-L-D-A?
- 52-position dual-row layout at 0.050" (1.27 mm) pitch providing high signal density in a compact PCB footprint
- Tiger Eye contact technology generating superior normal force for consistent electrical contact across thousands of mating cycles
- Low-profile through-hole mounting design reducing connector height and supporting vibration-resistant mechanical attachment to the PCB
- Cost-effective Tiger Eye series offering reliable performance comparable to premium connector families at a lower system cost
What is TFC-126-02-L-D-A used for?
The TFC-126-02-L-D-A is designed for high-density through-hole signal routing in backplane assemblies, mezzanine card interfaces, and embedded computing modules where 52 signals must be connected reliably in a compact 1.27 mm pitch footprint. It is commonly used in telecommunications equipment, industrial PLCs, and test-and-measurement instrumentation that require a low-profile connector with consistent contact performance. Its cost-effective Tiger Eye design also makes it suitable for cost-sensitive industrial and consumer electronics applications with moderate to high production volumes.

Frequently Asked Questions
How many positions does the TFC-126-02-L-D-A provide and what is its contact pitch?
The TFC-126-02-L-D-A offers 52 positions arranged in a dual-row format at a 0.050" (1.27 mm) pitch. This configuration routes 52 independent signals through a single compact connector, which reduces the total PCB area required for interconnect compared to using multiple lower-position-count connectors. It is well suited to embedded computing and telecom boards where channel count and board density both matter.
What does the low-profile (L) designation mean for TFC-126-02-L-D-A in stack-height-constrained designs?
The L suffix indicates a low-profile variant that keeps the connector's above-board height to a minimum, typically under 3 mm, which is critical in multi-board assemblies or enclosures with tight vertical clearances. A lower connector profile allows engineers to reduce the overall height of board stacks by 1 mm to 2 mm per interface level, enabling more compact system packaging in 1U rack-mount equipment, handheld instruments, and embedded module enclosures.
How does Tiger Eye contact technology in TFC-126-02-L-D-A compare to standard stamped contacts in terms of reliability?
Tiger Eye contacts are engineered to produce a significantly higher normal force at the mating interface than standard stamped contacts, which directly improves contact resistance stability and resistance to intermittent connections caused by vibration or thermal expansion. In the TFC-126-02-L-D-A this translates to contact resistance consistently below 20 milliohms across thousands of insertion cycles, outperforming conventional stamped contacts that may degrade after a few hundred cycles in demanding industrial or telecom environments.
Can the TFC-126-02-L-D-A be used in industrial control applications exposed to vibration and temperature variation?
Yes, the TFC-126-02-L-D-A is suited to industrial control applications where vibration and temperature cycling are present. The Tiger Eye contact design maintains high normal force even as the connector materials expand and contract across a wide temperature range, preventing the micro-motion that causes intermittent electrical contact. Its through-hole mounting provides stronger mechanical attachment to the PCB than surface-mount alternatives, adding further vibration resistance critical in factory automation and motor-control equipment.
