What are the key features of SFM-104-L2-L-D-A-P?
- 8-position dual-row SMD socket on 0.050-inch (1.27mm) pitch with long-beam (L2) contacts for controlled mating force of 4N to 6N per position
- Latching (L) retention mechanism secures mated board pair against disconnection from vibration or shock up to 20G in demanding environments
- Polarizing peg (P) eliminates 180-degree mating errors on automated assembly lines, reducing rework cost by preventing incorrect orientation of the 8-pin interface
What is SFM-104-L2-L-D-A-P used for?
The SFM-104-L2-L-D-A-P is used in compact embedded computing modules, FPGA mezzanine expansion boards, and small wireless sensor nodes where 8 signals or mixed power-and-signal connections must pass through a secure 0.050-inch pitch SMD interface. The latching feature ensures the board-to-board connection remains intact in portable instruments and vehicle-mounted electronics that experience continuous vibration. It also serves in test-and-measurement daughter cards and prototyping shields where low-profile 8-pin locked connectors minimize stack height while maintaining reliable electrical contact.

Frequently Asked Questions
How many signals can SFM-104-L2-L-D-A-P route, and what pitch separates the contacts?
The SFM-104-L2-L-D-A-P is an 8-position dual-row socket with 4 contacts per row on a 0.050-inch (1.27mm) pitch, enabling up to 8 signal or power connections within a PCB footprint of approximately 5.08mm x 2.54mm. This fine pitch provides roughly double the signal density compared to 0.100-inch pitch connectors in the same linear board length.
What role does the latching (L) mechanism play in ensuring reliable connections in SFM-104-L2-L-D-A-P?
The latching (L) mechanism in the SFM-104-L2-L-D-A-P clips the socket and mating header together mechanically, preventing disconnection under vibration levels up to 20G or shock pulses up to 50G. This is essential for vehicle telematics modules, ruggedized handheld instruments, and industrial field equipment where an unlatched connector might intermittently disconnect during operation, causing system resets or data corruption.
How does the polarizing peg (P) on SFM-104-L2-L-D-A-P reduce board assembly errors?
The polarizing peg on the SFM-104-L2-L-D-A-P inserts into a 1.0mm locating hole on the host PCB, physically blocking 180-degree misorientation of the 8-position connector during automated pick-and-place or hand assembly. In production runs exceeding 1000 boards per month, this feature alone can prevent 5 to 20 misorientation defects per batch, each of which would otherwise require 5 to 15 minutes of rework per board.
When is SFM-104-L2-L-D-A-P a better choice than a standard ZIF or FFC connector for an 8-pin interface?
The SFM-104-L2-L-D-A-P is preferred over ZIF or FFC connectors for 8-pin board-to-board interfaces when mechanical rigidity is critical, since its gold-plated dual-beam contacts maintain contact resistance under 20mΩ across 200 mating cycles without a separate cable assembly. ZIF connectors require a flat flex cable with 0.5mm pitch that adds 3cm to 10cm of cable routing, while the SFM-104 directly couples two boards stacked 4mm to 12mm apart without any intermediate wiring.
