Frequently Asked Questions
How many contact positions does the SFM-127-02-L-D-K-TR provide and at what pitch?
The SFM-127-02-L-D-K-TR provides 54 positions arranged in 2 rows at a 0.050" (1.27 mm) pitch, giving 27 contacts per row. This high-density dual-row layout supports routing of numerous signals between stacked PCBs within a footprint that is significantly smaller than 2.54 mm pitch alternatives, making it well-suited for compact industrial and medical board designs.
Which mating connectors are compatible with the SFM-127-02-L-D-K-TR socket strip in a stacked PCB design?
The SFM-127-02-L-D-K-TR is designed to mate with SAMTEC TSM and SFM series header connectors sharing the 0.050" (1.27 mm) pitch dual-row footprint. This family compatibility allows designers to select different stack heights and termination styles while keeping the 54-pin dual-row interface, enabling modular PCB-stacking architectures in test and measurement or industrial control equipment.
What assembly process is required to solder the SFM-127-02-L-D-K-TR onto a PCB?
The SFM-127-02-L-D-K-TR uses surface-mount termination compatible with standard lead-free reflow soldering profiles, and its tape-and-reel packaging format supports automated pick-and-place assembly. The 0.050" (1.27 mm) pitch pads require a precision solder paste stencil with apertures sized for fine-pitch SMT, and the connector body is rated for standard reflow temperatures used in high-volume PCB production.
