SFM-142-02-LM-D-A SAMTEC Connector (Other) In Stock
SAMTEC SFM-142-02-LM-D-A is a high-reliability 84-position dual-row surface-mount socket strip with a 0.050-inch (1.27 mm) pitch and a right-angle (low-profile) mounting orientation for space-constrained board-to-board interfaces. The dual-row contact arrangement provides 84 signal connections in a compact SMT footprint with high insertion-cycle reliability. Available in standard quantities with worldwide shipping for demanding industrial and test-equipment designs.

Key Features
- 84 contact positions in a dual-row layout at 0.050 inch (1.27 mm) pitch for high-density low-profile interconnects
- Right-angle (LM) low-profile surface-mount orientation enables horizontal mating ideal for stacked PCB assemblies
- High-reliability socket strip construction maintains consistent contact resistance and mating force over repeated insertion cycles
- Surface-mount termination supports automated SMT pick-and-place assembly without through-hole drilling operations
Applications
The SFM-142-02-LM-D-A is suited for low-profile board-to-board and edge-mount applications in FPGA evaluation platforms, rugged embedded computing, and test-and-measurement equipment that require 84 contacts in a tight 0.050-inch pitch configuration. Its right-angle SMT socket strip is commonly used in daughter-card and mezzanine module designs where vertical clearance is limited and horizontal connector mating is preferred. The high-reliability rating also makes it a strong choice for military, avionics, and industrial automation hardware operating in harsh environments.

Frequently Asked Questions
How does the SFM-142-02-LM-D-A differ from the SFM-142-02-FM-D-A in mounting orientation, and which applications benefit from each?
The SFM-142-02-LM-D-A uses a right-angle (LM) low-profile surface-mount orientation, while the SFM-142-02-FM-D-A uses a vertical (FM) mounting style. The right-angle variant is preferred when the mating connector approaches horizontally, reducing total assembly height by several millimetres in stacked-PCB enclosures; the vertical variant suits standard perpendicular board-to-board mating. Both provide 84 contacts at 0.050-inch (1.27 mm) pitch, so the footprint signal count is identical across both orientations.
What contact density does the SFM-142-02-LM-D-A provide, and how does the 0.050-inch pitch benefit space-constrained designs?
The SFM-142-02-LM-D-A provides 84 contacts in 2 rows at a 0.050-inch (1.27 mm) pitch, which is half the spacing of standard 0.1-inch (2.54 mm) pitch connectors. This tighter pitch concentrates 84 signal pins into a connector body roughly 27 mm long, approximately halving the board footprint compared to an equivalent 0.1-inch pitch dual-row connector, which is critical for small-form-factor boards in UAV flight controllers, portable test instruments, and wearable medical devices.
What does the high-reliability rating of the SFM-142-02-LM-D-A mean for connector mating cycle life?
The high-reliability designation from SAMTEC indicates the SFM-142-02-LM-D-A is constructed with materials and contact geometries that maintain stable electrical performance over an extended number of mating cycles, typically hundreds to thousands of insertions depending on the series. Contacts are engineered to hold contact resistance within milliohm-level tolerances even after repeated mating, which is essential in test fixtures, reconfigurable module bays, and field-replaceable units that undergo frequent board swaps in operating temperature ranges from -55°C to +125°C.
Which industries commonly specify SAMTEC SFM-142-02-LM-D-A, and what makes it a procurement-friendly choice?
The SFM-142-02-LM-D-A is specified in military/aerospace, industrial automation, medical imaging, and high-performance computing applications where 84-position dual-row 0.050-inch pitch connectors must meet reliability and solderability requirements over a broad temperature range. As a SAMTEC standard catalogue part, it is available through authorised distributors with short lead times, competitive per-unit pricing in quantities from 1 to thousands, and tape-and-reel or tray packaging options to accommodate both prototype and mass-production SMT assembly workflows.
