What are the key features of SFM-134-L2-S-D-A-K?
- 68-position dual-row socket strip at 0.050-inch (1.27 mm) pitch providing 34 contacts per row for very high signal density interconnection
- Extended L2 tail length improving solder joint pull strength and resistance to mechanical stress in vibration-prone industrial environments
- High-reliability female contact design rated for repeated mating cycles with consistent contact resistance below 20 milliohms per contact
- Surface mount configuration enabling automated pick-and-place and reflow soldering in high-volume PCB manufacturing workflows
What is SFM-134-L2-S-D-A-K used for?
The SFM-134-L2-S-D-A-K is designed for high-density board-to-board connections in FPGA development platforms, embedded processor carrier boards, and multi-channel signal conditioning modules where 68 positions at 0.050-inch pitch maximize interconnect within a compact footprint. The extended L2 tail variant provides added mechanical security in portable instruments, robotics controllers, and industrial automation boards subject to vibration and thermal cycling. This socket strip enables reliable dual-row mating for parallel data buses, mixed-signal interfaces, and multi-power-rail distribution in systems requiring high pin-count surface mount connectivity.

Frequently Asked Questions
What advantage does the L2 extended tail length provide on SFM-134-L2-S-D-A-K over standard tail variants?
The L2 extended tail on SFM-134-L2-S-D-A-K increases the solder joint length from the standard dimension to approximately 2 mm below the PCB surface, significantly improving solder pull-out strength. This is particularly valuable for 68-position connectors in applications subject to vibration or mechanical shock, where longer solder tails distribute stress across a greater solder fillet area and reduce the risk of joint fatigue failure over time.
How many signal lines can SFM-134-L2-S-D-A-K carry in a dual-row 0.050-inch pitch configuration?
The SFM-134-L2-S-D-A-K accommodates 68 signal positions arranged in 2 rows of 34 contacts each at 0.050-inch (1.27 mm) pitch. This enables routing of 64 data signals plus 4 dedicated power or ground pins — or any combination totaling 68 positions — within a connector body of approximately 43.2 mm in length, achieving roughly 1.58 positions per millimeter of connector length.
Which SAMTEC plug strip series mates with SFM-134-L2-S-D-A-K for an FPGA board-to-board stack?
SFM-134-L2-S-D-A-K mates with SAMTEC's TSM and SSM series terminal strips at 0.050-inch pitch, engaging all 68 positions in a dual-row configuration. The TSM mating plug is available in stack heights from 5 mm to over 20 mm, making the SFM-134-L2-S-D-A-K compatible with a wide range of board-to-board spacing requirements in FPGA carrier-to-mezzanine and processor-to-memory module stacking designs.
For a robotics controller requiring over 60 sensor and actuator signals on one connector, why is SFM-134-L2-S-D-A-K a practical choice?
SFM-134-L2-S-D-A-K provides 68 positions in a single compact connector body at 0.050-inch pitch, enough to carry 60 or more sensor/actuator signal lines plus power and ground in a footprint under 44 mm long. In robotics controllers subject to mechanical vibration, the extended L2 tail increases solder joint strength, while the dual-row 0.050-inch layout reduces wiring harness complexity compared to using multiple standard 0.100-inch pitch connectors across the same signal count.
