Key Features
- 72-position dual-row socket strip on 0.050" (1.27 mm) pitch for high-density interconnects
- Gold (10 micro-inch) over nickel (50 micro-inch) mating contacts for low contact resistance and corrosion resistance
- Beryllium copper contact material for superior spring force and long mating cycle life
- Polarized housing prevents incorrect mating orientation in automated or field assembly
- Surface-mount termination with matte tin-over-nickel finish for RoHS-compatible soldering
Applications
The SFM-136-02-L-D-A-P is suited for high-density board-to-board mezzanine connections in aerospace, defense, medical, and high-performance computing applications where long mating cycle life and signal integrity are critical. The 0.050 inch pitch and 72-position count allow significant pin density on compact PCBs. Polarization and gold contacts make this connector ideal for high-reliability systems subject to vibration or repeated mating cycles.

Frequently Asked Questions
What contact material and finish does SFM-136-02-L-D-A-P use, and how does it affect reliability?
The SFM-136-02-L-D-A-P uses beryllium copper contacts with gold (10 micro-inch) over nickel (50 micro-inch) mating finish. Beryllium copper provides strong spring force and long mating cycle life, while gold plating ensures low contact resistance even after repeated insertions, making it suitable for high-reliability applications.
How many positions and what pitch does SFM-136-02-L-D-A-P provide for high-density board connections?
The connector provides 72 positions in a dual-row configuration on a 0.050 inch (1.27 mm) pitch. This fine pitch makes SFM-136-02-L-D-A-P well-suited for mezzanine board stacking in space-constrained designs where high pin count must fit within a small PCB footprint.
In which industries is SFM-136-02-L-D-A-P commonly specified for mezzanine applications?
The SFM-136-02-L-D-A-P is frequently specified in aerospace, defense, and medical equipment due to its high-reliability gold contacts and polarized housing. It also sees use in high-performance computing and test systems where 72 pins at 1.27 mm pitch allow dense signal routing between stacked PCBs.
Does the polarization feature on SFM-136-02-L-D-A-P reduce the risk of mis-mating during assembly?
Yes. The polarized housing ensures correct connector orientation and prevents accidental reverse insertion, which is critical in 72-pin dual-row connectors used in automated assembly lines or field replaceable modules. This reduces the risk of bent pins or damage to the beryllium copper contacts.
