Key Features
- 72-position dual-row layout on 0.050" (1.27 mm) pitch delivering 36 contacts per row in a compact high-density footprint
- High-reliability socket strip construction rated for multiple insertion cycles in demanding aerospace and industrial environments
- Surface-mount low-profile horizontal orientation minimizing stack height for thin board-to-board assemblies
- Tape-and-reel (TR) packaging supporting automated SMT pick-and-place for high-volume production
Applications
The SFM-136-02-L-D-A-K-TR is engineered for high-density board-to-board interconnect in applications such as aerospace avionics modules, defense electronics, and high-performance computing daughtercard sockets where 72 signals must be routed on a 0.050" pitch footprint. Its high-reliability construction withstands vibration and thermal cycling, making it suitable for industrial automation controllers and ruggedized test equipment. The surface-mount form factor integrates directly with automated SMT assembly lines, reducing assembly cost in volume production of embedded computing and communications hardware.

Frequently Asked Questions
How many contacts does the SFM-136-02-L-D-A-K-TR carry, and how does the 0.050" pitch affect board layout density?
The SFM-136-02-L-D-A-K-TR has 72 total contacts arranged in a 2×36 dual-row configuration on a 0.050" (1.27 mm) pitch. Compared to a 0.100" pitch connector with the same contact count, this part occupies roughly half the PCB length, enabling high-density signal routing on constrained daughtercard designs in aerospace and defense modules.
For which high-reliability application scenarios is the SFM-136-02-L-D-A-K-TR specified instead of a standard 0.100" socket strip?
This connector is specified in aerospace avionics, military electronics, and ruggedized industrial systems where the combination of 72 contacts, 0.050" pitch, and high-reliability construction is needed to survive vibration levels above 10 g and temperature cycling from -55 °C to +125 °C. Standard 0.100" strips cannot achieve the same contact density in the available board area, and their lower-grade plating is not rated for the insertion-cycle or environmental requirements of these applications.
Does the SFM-136-02-L-D-A-K-TR support automated SMT assembly, and what reel quantity is typically available?
Yes. The TR suffix designates tape-and-reel packaging, which is compatible with automated SMT pick-and-place machines and standard 260 °C peak lead-free reflow profiles. SAMTEC typically packages SFM series connectors in reels of 100 to 500 pieces, making this part suitable for medium-to-high volume production runs of embedded computing boards, communications hardware, and test instrumentation without manual insertion labor.
What mating connectors are compatible with the SFM-136-02-L-D-A-K-TR for a board-to-board stack?
The SFM series is designed to mate with SAMTEC TSM or TFM series 0.050" pitch header strips in a 2×36 dual-row configuration. The mated stack height is typically 2 mm to 8 mm depending on the selected header height variant, allowing system designers to choose a board separation that fits their enclosure constraints while maintaining the full 72-pin signal capacity required for mixed data and power routing.
