What are the key features of TFM-127-01-FM-D-A-P-TR?
- 54-position dual-row surface-mount Tiger Eye terminal strip at 0.050" (1.27 mm) pitch providing high-density right-angle board-to-board mating in compact electronic assemblies
- Tiger Eye contact technology delivering high normal force and extended contact wipe for reliable electrical performance across many mating cycles in vibration and shock environments
- Tape-and-reel (TR) packaging enabling seamless integration with high-speed pick-and-place SMT assembly equipment for efficient high-volume PCB production
What is TFM-127-01-FM-D-A-P-TR used for?
The TFM-127-01-FM-D-A-P-TR is designed for high-density right-angle board-to-board connections in telecommunications line cards, defense electronics, and industrial control modules where 54 signals must be routed between perpendicular PCBs at a compact 0.050" pitch. Its Tiger Eye contacts ensure reliable mating across the extended temperature range of -55°C to +125°C. Tape-and-reel packaging supports automated assembly in high-volume production environments, reducing placement time and component handling costs.

Frequently Asked Questions
How many positions does the TFM-127-01-FM-D-A-P-TR offer and in what orientation is it configured?
The TFM-127-01-FM-D-A-P-TR provides 54 positions in a dual-row (27 per row) right-angle surface-mount configuration at 0.050" (1.27 mm) pitch. The right-angle orientation allows two PCBs to mate perpendicularly, which is useful in compact enclosures and stacked board assemblies where vertical space is limited to under 10 mm.
What contact technology is used in the TFM-127-01-FM-D-A-P-TR and why is it preferred for high-reliability applications?
The TFM-127-01-FM-D-A-P-TR uses Tiger Eye contacts, which provide a longer wipe distance and higher normal force compared to standard bifurcated or tuning-fork contacts. This results in contact resistance maintained below 20 milliohms across a minimum of 30 mating cycles, even under mechanical shock above 50 G or thermal cycling between -55°C and +125°C in aerospace and defense equipment.
Is the TFM-127-01-FM-D-A-P-TR available in tape-and-reel format and what assembly process does it support?
Yes, the TFM-127-01-FM-D-A-P-TR is supplied in tape-and-reel (TR) format compatible with standard 12 mm or 16 mm carrier tape used by automated pick-and-place equipment. It supports standard SMT reflow profiles with peak temperatures up to 260°C per IPC/JEDEC J-STD-020, enabling high-volume production integration without manual handling of individual connectors.
When should an engineer choose the TFM-127-01-FM-D-A-P-TR over a lower-pitch alternative for a new board design?
At 0.050" (1.27 mm) pitch, the TFM-127-01-FM-D-A-P-TR occupies roughly half the board length of a 0.100" pitch 54-pin alternative, making it the preferred choice when PCB real estate is constrained to under 35 mm in the connector axis. It is particularly beneficial in multi-board system designs where reducing connector footprint by 50% frees routing channels for high-speed differential pairs operating at 1 Gbps or higher.
