Key Features
- 8-position dual-row 0.050" (1.27 mm) pitch socket strip enables high-density mating at 4 contacts per row in a space-saving surface-mount footprint
- Latch-mount (LM) retention mechanism provides positive mechanical lock during mating, preventing unintended disconnection in vibration-prone environments
- High-reliability construction rated for 1000+ mating cycles with beryllium copper contacts maintaining contact resistance below 20 mΩ from -55°C to +125°C
Applications
The SFM-104-L2-LM-D-A is used for high-density board-to-board and board-to-flex signal interconnect in compact embedded systems, portable medical devices, and aerospace instrumentation where positive locking retention prevents signal loss from vibration or shock. Its 8-position dual-row layout at 1.27 mm pitch saves up to 40% board space compared to 2.00 mm pitch equivalents while supporting 1 A per contact current handling. The low-profile latch-mount termination style simplifies automated assembly and ensures repeatable mating engagement across high-cycle production test fixtures.

Frequently Asked Questions
How does the latch-mount feature of the SFM-104-L2-LM-D-A improve connector reliability?
The latch-mount (LM) mechanism on the SFM-104-L2-LM-D-A provides a positive mechanical lock when fully mated, requiring deliberate lateral actuation to release. This prevents accidental unmating under vibration levels common in industrial machinery or airborne equipment, maintaining contact resistance below 20 mΩ throughout the rated 1000+ mating cycle life.
What is the pin count, row configuration, and pitch of the SFM-104-L2-LM-D-A?
The SFM-104-L2-LM-D-A has 8 total positions in a dual-row configuration with 4 contacts per row, spaced at the industry-standard fine-pitch 0.050" (1.27 mm) centerline. This configuration is optimized for routing 4 differential pairs or 8 single-ended signals in the smallest possible footprint for surface-mount board-to-board applications.
For which space-constrained applications is the SFM-104-L2-LM-D-A a better choice than a 2.00 mm pitch socket strip?
The SFM-104-L2-LM-D-A at 1.27 mm pitch is preferred in wearable medical sensors, miniature avionics modules, and SSD mezzanine cards where board area is critically limited. Moving from 2.00 mm to 1.27 mm pitch reduces the connector footprint by approximately 40%, freeing space for additional signal routing or power components on the same PCB layer.
What current capacity does each contact in the SFM-104-L2-LM-D-A support?
Each contact in the SFM-104-L2-LM-D-A is rated for approximately 1 A continuous current. With 8 contacts available, multiple pins can be paralleled to supply power rails at several amperes alongside signal channels, making the connector versatile for mixed power and data interfaces in compact embedded designs operating between -55°C and +125°C.
