What are the key features of SFM-110-L2-STL-D-A-P-TR?
- 20-position dual-row configuration at 0.050" (1.27 mm) pitch for medium-density signal routing in compact SMT connector footprints
- Long-tail (STL) SMT lead style provides extended solder joints for improved mechanical retention on the PCB pad
- High-reliability gold-plated dual-beam contacts ensure consistent low-resistance mating across multiple insertion cycles
- Surface-mount termination with pick-and-place compatible carrier tape packaging for automated high-volume PCB assembly
What is SFM-110-L2-STL-D-A-P-TR used for?
The SFM-110-L2-STL-D-A-P-TR is used in medium-density board-to-board signal interconnect applications in industrial control systems, data acquisition modules, and communications hardware where 20 signals must be reliably routed at 0.050" (1.27 mm) pitch. Its long-tail SMT lead style improves solder joint strength, making it suitable for vibration-prone industrial and automotive auxiliary electronics. The connector is commonly specified in FPGA evaluation boards, motor driver modules, and sensor interface cards requiring reliable dual-row SMT socket connections.

Frequently Asked Questions
What does the STL lead style on the SFM-110-L2-STL-D-A-P-TR mean for PCB assembly?
The STL (long-tail) lead style on the SFM-110-L2-STL-D-A-P-TR means the SMT leads extend further below the connector body compared to standard lead lengths, providing a larger solder fillet area per contact. This increases solder joint mechanical strength and reduces the risk of joint fracture under vibration or thermal cycling stress in industrial and automotive auxiliary PCB applications.
How many signal positions does the SFM-110-L2-STL-D-A-P-TR provide, and how are they arranged?
The SFM-110-L2-STL-D-A-P-TR provides 20 total positions arranged in a dual-row configuration of 10 contacts per row at a 0.050" (1.27 mm) pitch. This medium-density layout suits parallel bus interfaces, multi-channel sensor connections, and control signal groupings that need between 16 and 24 pins in a compact surface-mount board-to-board connector.
For which applications is the SFM-110-L2-STL-D-A-P-TR more appropriate than the 4-position SFM-102 or 32-position SFM-116?
The SFM-110-L2-STL-D-A-P-TR at 20 positions bridges the gap between the 4-position SFM-102 and the 32-position SFM-116, both at 1.27 mm pitch. It suits applications such as FPGA-to-sensor daughterboards, motor control daughtercards, and 16-bit parallel data buses that require more than 4 contacts but do not need the full 32-position capacity, avoiding oversized footprints and unnecessary connector cost.
What packaging does the SFM-110-L2-STL-D-A-P-TR ship in, and why does this matter for automated assembly?
The SFM-110-L2-STL-D-A-P-TR is supplied in carrier tape and reel packaging (TR suffix), making it fully compatible with automated pick-and-place equipment for SMT assembly lines. Tape-and-reel packaging supports high-volume PCB production by eliminating manual placement, reducing placement error rates, and enabling uninterrupted reel feeding on standard SMT assembly machines used in industrial and electronics manufacturing.
