Key Features
- 22-position dual-row socket at 0.050" (1.27 mm) pitch offering compact high-density board-to-board connectivity in surface mount footprint
- Tiger Eye beryllium copper contacts with gold over nickel plating ensure reliable low-resistance mating across hundreds to thousands of insertion cycles
- Tape-and-reel (TR) format compatible with automated pick-and-place SMT lines for high-volume production of embedded and telecom modules
Applications
SFM-111-02-ZZ-D-A-K-TR is suited for 22-signal board stacking applications in compact embedded computing modules, wireless communication boards, and small industrial interface cards where 0.050" pitch minimizes connector footprint versus 0.100" alternatives. Its Tiger Eye contacts maintain reliable signal integrity in applications subject to vibration or repeated board removal, such as modular PLC systems and field-replaceable unit (FRU) boards in telecom. The tape-and-reel packaging supports automated SMT production for consumer electronics and IoT gateways requiring compact multi-signal interconnects.

Frequently Asked Questions
How compact is the SFM-111-02-ZZ-D-A-K-TR for a 22-position dual-row socket at 0.050" pitch?
SFM-111-02-ZZ-D-A-K-TR spans approximately 0.55" (14 mm) for its 11 positions per row at 0.050" pitch, making it significantly more compact than a 0.100" pitch equivalent that would require about 1.1" for the same 22-position dual-row count. This space saving is critical on small embedded modules, radio boards, and IoT devices where PCB area is limited to less than 30 mm × 30 mm.
What is the mating cycle reliability of SFM-111-02-ZZ-D-A-K-TR's Tiger Eye contacts?
SFM-111-02-ZZ-D-A-K-TR uses Tiger Eye beryllium copper contacts, which are engineered for high mating cycle durability. The beryllium copper spring maintains consistent normal force against mating pins across the rated temperature range of -55°C to +125°C, ensuring stable contact resistance below 20 milliohms through hundreds of insertion and withdrawal cycles across all 22 positions in field-replaceable module applications.
For a wireless module board needing 22 signals between boards, what makes SFM-111-02-ZZ-D-A-K-TR an appropriate choice?
SFM-111-02-ZZ-D-A-K-TR provides 22 dual-row positions at 0.050" pitch, accommodating a typical wireless module's RF control lines, power rails, UART, SPI, and GPIO signals in a single 0.55" connector. The gold over nickel contact finish maintains low contact resistance in the humid or thermally varying environments typical of IoT gateways, and the SMT footprint avoids through-hole vias that would block inner layer routing on dense 4-layer or 6-layer wireless module PCBs.
Does SFM-111-02-ZZ-D-A-K-TR support automated reflow assembly and what does the TR packaging indicate?
Yes, the TR suffix denotes tape-and-reel packaging, which feeds directly into automated pick-and-place machines for SMT reflow assembly. The 22-pin dual-row footprint at 0.050" pitch requires precise placement accuracy achievable only by automated equipment, and the tape-and-reel format maintains connector orientation and protects the Tiger Eye contacts from contamination during storage and assembly at rates of thousands of units per hour.
