What are the key features of SFM-148-T2-LM-D-LC?
- 96-position dual-row layout at 0.050" (1.27 mm) pitch enabling maximum signal density in compact board-to-board interconnects
- Low-clearance (LC) mating profile reduces the inter-board stack height to a few millimeters for space-constrained layered assemblies
- Metal retention (LM) contacts provide enhanced mechanical pull strength and improved EMI shielding versus standard plastic-retained contacts
- Tiger Eye contact geometry delivers high normal force for reliable gas-tight electrical connections over thousands of mating cycles
- Surface mount design compatible with standard SMT reflow assembly, eliminating through-hole drilling on 96-pin interfaces
What is SFM-148-T2-LM-D-LC used for?
The SFM-148-T2-LM-D-LC is suited for high-density board-to-board interconnects in FPGA mezzanine cards, ruggedized computing modules, and defense avionics boards where 96 signal paths must pass through a single 0.050" pitch socket in a low-profile stack. Its low-clearance design is critical for multi-board assemblies where inter-board spacing must be minimized to a few millimeters. The metal retention contacts also make it a reliable choice for vibration-resistant industrial and aerospace equipment requiring stable electrical connections across a wide temperature range.

Frequently Asked Questions
How many contact positions does the SFM-148-T2-LM-D-LC provide, and at what pitch are they spaced?
The SFM-148-T2-LM-D-LC provides 96 positions in a dual-row configuration at 0.050" (1.27 mm) pitch, with 48 contacts per row. This 96-position count makes it one of the higher-density variants in the SAMTEC SFM series, supporting applications such as FPGA daughter board interfaces, high-channel-count data acquisition systems, and embedded processor mezzanine cards that need to route dozens of parallel signals through a single compact connector footprint.
What does the LC suffix mean in SFM-148-T2-LM-D-LC, and how does it affect PCB stack height?
The LC suffix designates a low-clearance variant, meaning the mated board-to-board stack height achieved with a compatible SAMTEC plug header is reduced compared to standard SFM connectors. This low-profile mating configuration is designed for layered PCB assemblies where inter-board spacing must be kept to approximately 4 mm to 8 mm, making the SFM-148-T2-LM-D-LC well-suited for compact embedded computing enclosures, stacked module designs, and portable instruments with tight mechanical envelopes.
What is the LM contact variant in SFM-148-T2-LM-D-LC, and how does it benefit high-reliability applications?
The LM suffix denotes a metal (low-profile metal) retention contact design that integrates a metallic retention tab into the contact structure. This metal retention provides significantly higher mechanical pullout force compared to standard plastic-retained contacts, improving connector retention under vibration and shock loads. For defense electronics, aerospace avionics, and industrial equipment operating at temperatures from -55°C to +125°C, the LM design also contributes to better EMI containment across the 96-position interface.
Which mating connector families are compatible with the SFM-148-T2-LM-D-LC socket strip?
The SFM-148-T2-LM-D-LC mates with SAMTEC's dual-row board-to-board plug headers in the TSM, FLE, and THM series at 0.050" (1.27 mm) pitch. The D (dual-row) coding and low-clearance (LC) height requirement mean designers must select a compatible low-profile mating plug to achieve the intended stack height. SAMTEC's online connector configurator can match 96-position LC plugs to this socket, ensuring correct mating depth and contact engagement across all 96 pins.
For which industries and system designs is the SFM-148-T2-LM-D-LC most commonly specified?
The SFM-148-T2-LM-D-LC is most commonly specified in defense radar and signal processing boards, aerospace avionics line-replaceable units (LRUs), medical imaging systems, and high-performance industrial controllers where 96 reliable signal connections at 0.050" pitch are required within a low-profile stack. The combination of Tiger Eye contacts, metal retention, and low-clearance mating ensures the connector meets MIL-spec vibration, shock, and temperature requirements for -55°C to +125°C operational environments.
