What are the key features of SFM-144-L2-H-D-A-K?
- 88 positions at 0.050" (1.27 mm) pitch in a dual-row right-angle SMT layout, providing high-density horizontal mating for low-profile board-edge interconnects
- High-reliability gold-plated contacts support extended mating cycles and low insertion force, maintaining reliable electrical contact across 44 signal pairs per row
- Right-angle (L) termination style allows horizontal daughter board mating parallel to the PCB plane, saving vertical clearance in compact enclosures
What is SFM-144-L2-H-D-A-K used for?
SFM-144-L2-H-D-A-K is designed for high-density board-edge and horizontal mezzanine interconnects in communications infrastructure, test equipment, and embedded computing platforms. The right-angle orientation supports designs where daughter cards must mate horizontally to a main board due to chassis height restrictions below 15 mm. Its 88-position, 0.050" pitch layout accommodates high pin-count FPGA and DSP expansion modules in rack-mount and panel-mount system architectures.

Frequently Asked Questions
How does the right-angle termination of SFM-144-L2-H-D-A-K differ from vertical SMT socket strips?
SFM-144-L2-H-D-A-K uses a right-angle (L) SMT termination, causing the 88-position, 0.050" pitch socket to mate horizontally rather than vertically. This orientation reduces the assembled height of a mated daughter-card pair to under 10 mm, compared to 20 mm or more for vertical mating styles, benefiting enclosures with tight height clearance.
What signal density does SFM-144-L2-H-D-A-K support for high-speed differential interfaces?
The dual-row, 88-position, 0.050" (1.27 mm) pitch layout of SFM-144-L2-H-D-A-K accommodates up to 44 differential pairs, supporting high-speed interfaces such as LVDS, MIPI, or SERDES running at several Gbps per lane. The 1.27 mm pitch maintains controlled impedance and crosstalk performance needed for multi-gigabit signal routing on compact PCBs.
When should a designer choose SFM-144-L2-H-D-A-K over the vertical-mount SFM-144-T2-FM-D-A-K variant?
SFM-144-L2-H-D-A-K (right-angle, L termination) is preferred when the mated daughter board must lie parallel to the main PCB surface within an enclosure limited to less than 15 mm internal height. The vertical T2 variant suits open-frame or deeper chassis where upright daughter boards are acceptable, whereas the L2 right-angle style trades 5–8 mm of vertical clearance for horizontal board-to-board stacking across 88 positions at 0.050" pitch.
