Frequently Asked Questions
How many positions does the TSM-127-02-SS-DH-A-K-TR provide, and what pitch does it use?
The TSM-127-02-SS-DH-A-K-TR provides 54 positions in a dual-row layout with a 0.100 inch (2.54 mm) pitch, giving designers a standard-density SMT terminal strip for embedded boards, test fixtures, and industrial signal headers.
Does tape-and-reel packaging on the TSM-127-02-SS-DH-A-K-TR support automated PCB production?
Yes. The TR suffix confirms tape-and-reel packaging, enabling automated pick-and-place placement at high throughput. All 54 positions are surface mount, making this connector fully compatible with standard lead-free reflow solder profiles up to 260°C.
When should an engineer choose this 54-position strip over a 40-position or 64-position SAMTEC TSM header?
Choose the 54-position TSM-127-02-SS-DH-A-K-TR when the design requires exactly 54 I/O signals on a 2.54 mm pitch, balancing connector length and signal count. A 40-pin variant is shorter but reduces capacity; a 64-pin version adds 10 signals but increases board footprint.
What industries and PCB form factors benefit most from this dual-row SMT terminal strip?
Embedded development kits, automated test equipment, and industrial PLCs benefit most, since the dual-row 2.54 mm pitch layout provides 54 contacts in a footprint roughly 3.5 inches long, fitting standard Eurocard and SBC form factors for modular backplane designs.
