What are the key features of SFM-123-02-FM-D-A-P-TR?
- 46-position dual-row socket at 0.050 inch (1.27 mm) pitch delivering high signal density in a compact SMT footprint for space-constrained PCBs
- High-reliability SFM socket strip construction with precision-machined contacts engineered for extended mating cycle life in demanding industrial and aerospace environments
- Tape-and-reel (TR) packaging for seamless automated SMT pick-and-place integration, reducing placement errors and supporting high-volume production throughput
What is SFM-123-02-FM-D-A-P-TR used for?
The SFM-123-02-FM-D-A-P-TR is used in high-density mezzanine card assemblies, FPGA daughter board interfaces, and rugged embedded computing modules where 46 contacts must be interconnected at 0.050 inch pitch in a surface mount topology. Its high-reliability socket design supports applications such as mil-aero avionics I/O boards, industrial machine vision systems, and communications line cards that demand consistent electrical performance across thousands of mating cycles. The dual-row layout efficiently routes both signal and ground references within a minimal PCB area.

Frequently Asked Questions
What contact pitch and total position count does the SFM-123-02-FM-D-A-P-TR provide for board stacking designs?
The SFM-123-02-FM-D-A-P-TR uses a 0.050 inch (1.27 mm) pitch and provides 46 positions in a dual-row arrangement, yielding 92 total contacts per mated pair. This fine pitch allows system designers to accommodate a large signal count within a PCB footprint roughly half the size of an equivalent 0.100 inch pitch connector, which is critical in compact embedded computing and high-density I/O expansion modules.
How does the SFM series high-reliability socket construction benefit mil-aero or industrial applications with frequent board swapping?
SAMTEC's SFM high-reliability socket strips feature precision-formed contact springs that maintain consistent normal force and low contact resistance through extended mating cycles, often rated for 200 or more insertions. In mil-aero avionics or industrial field-replaceable unit (FRU) designs where modules may be exchanged during maintenance, this durability reduces connector-related failures and ensures stable signal continuity at 0.050 inch pitch across the full -55°C to +125°C operating temperature range.
For a dual-channel high-speed serial interface routed at 3 Gbps, can SFM-123-02-FM-D-A-P-TR support the signal integrity requirements?
The SFM series at 0.050 inch pitch is characterized for high-speed signal transmission, and SAMTEC typically rates SFM connectors for data rates in the multi-Gbps range with matched impedance. For 3 Gbps differential pairs, the 1.27 mm pitch allows adequate spacing between signal and adjacent ground contacts to maintain controlled impedance close to 50 ohms or 100 ohms differential, provided the PCB stackup and routing follow SAMTEC's recommended design guidelines for the SFM footprint.
Does the SFM-123-02-FM-D-A-P-TR ship in a format suitable for automated SMT assembly, and what is the reel orientation?
Yes, the -TR suffix confirms the SFM-123-02-FM-D-A-P-TR is supplied on tape-and-reel, packaged for automatic SMT pick-and-place machines. The tape carrier orients all connectors in the same direction so vision systems and nozzle heads can pick and place each unit consistently without manual pre-alignment. This reduces cycle time per board and eliminates orientation-related placement defects common with bulk-bag connector supply in high-volume PCB assembly environments.
