Key Features
- 44-position dual-row layout at 0.050" (1.27 mm) pitch providing 22 contacts per row in a compact SMT footprint
- Polarization post (P suffix) preventing mis-mating in field-replaceable module designs with 44-pin dual-row interfaces
- High-reliability gold-plated contacts engineered for low insertion force and extended mating cycle durability
- Tape-and-reel format enabling automated SMT pick-and-place assembly for high-volume production efficiency
Applications
The SFM-122-02-L-D-A-P-TR is suited for board-to-board socket applications in medical devices, industrial automation, and compact computing modules that need 44 signal contacts at 0.050" pitch with positional keying. Its polarization post ensures correct module orientation during both automated assembly and manual field insertion, minimizing risk of damage to the 44-pin dual-row interface. The high-reliability contact design supports applications requiring reliable electrical connections across wide temperature ranges and repeated mating cycles.

Frequently Asked Questions
How many contacts per row does the SFM-122-02-L-D-A-P-TR provide and how does this benefit compact PCB designs?
The SFM-122-02-L-D-A-P-TR provides 22 contacts per row across 2 rows for a total of 44 positions at 0.050" (1.27 mm) pitch, fitting all 44 contacts within a connector body approximately 28 mm long. This compact form factor allows designers to route 44 digital or analog signals between two stacked PCBs in a smaller footprint than a 0.100" pitch connector with the same pin count, which would require roughly 56 mm of board length for the same 44 contacts.
In what failure scenario does the polarization post on the SFM-122-02-L-D-A-P-TR prevent hardware damage?
Without a polarization post, a technician could insert the 44-position mating header rotated 180 degrees, connecting all 44 signals to incorrect pins and potentially shorting power to signal lines or applying reverse polarity to sensitive components. The polarization post on the SFM-122-02-L-D-A-P-TR physically blocks this incorrect insertion at 0.050" (1.27 mm) pitch, which is especially critical because the fine-pitch contacts are too small for visual pin-1 confirmation under typical field lighting conditions.
How does the SFM-122-02-L-D-A-P-TR compare to a through-hole socket strip of the same pin count for medical device assembly?
The SFM-122-02-L-D-A-P-TR uses surface-mount termination at 0.050" (1.27 mm) pitch, which eliminates the need for through-hole drilling and wave-soldering steps required for equivalent 44-position through-hole socket strips. In medical device PCB assembly, the SMT format reduces board layers needed for via routing, enables 2-sided component placement, and lowers assembly cost per board. The tape-and-reel packaging also allows the SFM-122-02-L-D-A-P-TR to be placed by automated equipment alongside other SMT components in a single reflow pass.
