What are the key features of SFM-120-02-LM-D-LC?
- 40 positions in dual-row layout at 0.050" (1.27 mm) pitch for compact high-density interconnect
- Low-clearance (LC) contact design minimizes mated stack height for slim PCB assemblies
- High reliability socket construction rated for many mating cycles in modular board designs
- Surface-mount (LM) termination supporting automated reflow soldering on standard SMT lines
- Dual-row configuration provides sufficient contacts for combined power and high-speed signal routing
What is SFM-120-02-LM-D-LC used for?
The SFM-120-02-LM-D-LC is used in modular sensor interfaces, compact FPGA daughter cards, and embedded communication modules where 40 contacts at 0.050-inch pitch must fit in a constrained PCB area. Its low-clearance design keeps the board-to-board stack height minimal, ideal for slim portable devices and space-restricted industrial enclosures. The high-reliability socket withstands repeated mating cycles in field-replaceable module systems and development platforms.

Frequently Asked Questions
How many signal paths does SFM-120-02-LM-D-LC support and at what pitch?
The SFM-120-02-LM-D-LC provides 40 contact positions in a dual-row layout at 0.050-inch (1.27 mm) pitch, enabling routing of multiple SPI, UART, or I2C buses plus power rails in a connector footprint roughly half the length of equivalent 0.100-inch pitch options.
Why is the low-clearance (LC) feature of SFM-120-02-LM-D-LC important for slim portable devices?
The LC designation indicates a contact geometry that reduces the physical gap between mated PCBs after soldering. In slim portable instruments, wearable boards, or tightly packed IoT modules, keeping the inter-board clearance to a few millimeters enables thinner enclosures and more compact mechanical designs without sacrificing electrical connectivity.
For a field-replaceable sensor module, how does the high-reliability socket in SFM-120-02-LM-D-LC perform over repeated mating?
SAMTEC's high-reliability SFM series socket contacts maintain consistent electrical performance across many insertion and removal cycles. In field-replaceable sensor modules and diagnostic boards, this durability ensures that 40 contacts remain within specified contact resistance limits after repeated swapping, reducing maintenance costs and connector-related field failures.
Does SFM-120-02-LM-D-LC require tape-and-reel packaging for automated SMT assembly?
The SFM-120-02-LM-D-LC model number does not include a TR suffix, indicating it is not supplied in tape-and-reel format by default and is typically sold in tray or strip packaging. Designers planning high-volume automated SMT assembly should verify packaging availability with the distributor, as bulk tray packaging still works with semi-automated or manual placement for lower-volume runs of a few hundred units.
