Key Features
- 54-position dual-row configuration with 0.050" (1.27 mm) pitch for high-density SMT board interconnects
- High-reliability stamped contacts rated for up to 1.0 A continuous current and 125°C operating temperature
- Surface mount termination style enabling automated PCB assembly with consistent solder joint quality
Applications
The SFM-127-02-SM-D-A-K-TR is suited for board-to-board and board-to-module signal interconnects in communications equipment, industrial control systems, and test and measurement instruments. Its 0.050" pitch and dual-row layout allow designers to route 54 signals through a compact 27-column footprint, reducing PCB area compared to 0.100" alternatives. The SMT termination style supports high-volume reflow assembly in consumer electronics and embedded computing platforms.

Frequently Asked Questions
What is the contact current rating and operating temperature range of the SFM-127-02-SM-D-A-K-TR?
The SFM-127-02-SM-D-A-K-TR is rated for 1.0 A per contact and can operate continuously up to 125°C. The 0.050" (1.27 mm) pitch dual-row design maintains these ratings across all 54 positions, making it suitable for signal-level power distribution in dense PCB layouts.
Which board-level interconnect scenarios benefit most from the 0.050" pitch dual-row layout of the SFM-127-02-SM-D-A-K-TR?
Applications requiring 54 signal paths within a tight PCB footprint benefit most from this connector. The 1.27 mm pitch reduces routing area by up to 50% compared to 2.54 mm alternatives, making it ideal for mezzanine board stacking, daughter-card interfaces, and high-density backplane connections in industrial and communications equipment.
How does the SMT termination style of the SFM-127-02-SM-D-A-K-TR affect assembly process requirements?
The surface mount termination allows standard reflow soldering at typical lead-free profiles peaking around 260°C. No through-hole drilling is required, reducing PCB fabrication cost and enabling placement by pick-and-place machines. This supports automated, high-volume assembly lines where cycle time and placement accuracy across all 54 positions are critical.
When would the SFM-127-02-SM-D-A-K-TR be a preferred alternative to a through-hole socket strip with the same pin count?
The SFM-127-02-SM-D-A-K-TR is preferred when board thickness is constrained below 1.6 mm or when both PCB sides must remain accessible. Its SMT pads occupy only one layer, while through-hole pins consume barrel space through all 54 drill holes. For automated assembly lines with high placement volumes, the SMT version also reduces handling steps.
