- Cost-effective Tiger Buy pricing tier enabling budget-conscious BOM optimization without sacrificing reliability
- Through-hole body style (0.881 inch length, 0.25 inch depth) compatible with wave and selective soldering processes
What is SQT-111-01-L-D used for?
The SQT-111-01-L-D is designed for rugged board-to-board socketing in industrial automation, test-and-measurement instruments, and embedded control systems where vibration resistance and repeated module swap are required. The 2.00 mm pitch dual-row layout carries 22 signals in a compact 0.881 inch body, suitable for removable peripheral modules, mezzanine cards, and plugin sensor boards. FlexYZ contact geometry maintains reliable electrical contact through thermal cycling between -55 degrees C and +125 degrees C, making it suitable for harsh industrial and automotive-adjacent environments.

Frequently Asked Questions
What is the FlexYZ Tiger Buy contact technology in SQT-111-01-L-D and why does it matter?
FlexYZ is a SAMTEC contact beam geometry that deflects in both the Y and Z axes, providing a normal force of approximately 100 grams per contact at the 2.00 mm pitch. This dual-axis compliance compensates for PCB warpage and thermal expansion mismatches, maintaining contact resistance below 20 milliohms across 100 or more mating cycles. The Tiger Buy designation identifies a cost-optimized product tier that retains the FlexYZ contact performance at a reduced price point.
For a removable sensor module at 2.00 mm pitch with 22 I/O connections, how does SQT-111-01-L-D handle repeated insertion?
The gold (10 µin) over nickel (50 µin) contact finish on each of the 22 positions provides a hard, low-oxidation mating surface rated for at least 50 insertion cycles without significant contact resistance increase. The FlexYZ beam self-wipes during each insertion, clearing minor oxidation or particulate contamination, which is important for field-replaceable sensor modules in dusty industrial environments operating between -40 degrees C and +85 degrees C.
How does the 2.00 mm pitch of SQT-111-01-L-D compare to 2.54 mm pitch alternatives for a compact PCB layout?
At 2.00 mm pitch the 22-position SQT-111-01-L-D body measures 0.881 inch in length, versus approximately 1.08 inch for an equivalent 22-position 2.54 mm pitch socket. This 18 percent length reduction saves over 5 mm of PCB edge space, allowing a narrower module form factor or additional routing channels adjacent to the socket in compact industrial instruments.
What soldering method is compatible with SQT-111-01-L-D for production assembly?
The SQT-111-01-L-D through-hole body is compatible with both wave soldering and selective soldering processes. Wave soldering at 260 degrees C for a contact time under 5 seconds achieves reliable fillet formation across all 22 through-hole positions. Selective soldering is preferred when adjacent SMT components on the same board cannot tolerate full wave immersion, providing flux and solder only to the 2.00 mm pitch through-hole footprint.
