What are the key features of TSM-127-03-TL-DH-A-P-TR?
- 54 total contacts in dual-row configuration on 0.100 inch (2.54 mm) pitch
- Polarizing post (P option) for keyed, fool-proof mating connector orientation
- Through-hole locating pins for accurate PCB registration during reflow soldering
- Surface mount termination compatible with lead-free reflow soldering processes
- Tape-and-reel (TR) packaging enabling automated SMT pick-and-place assembly
What is TSM-127-03-TL-DH-A-P-TR used for?
The TSM-127-03-TL-DH-A-P-TR is designed for industrial control boards, embedded processor modules, and backplane interface PCBs that require a 54-pin keyed dual-row terminal strip at 0.100 inch pitch. The polarizing post prevents reverse-insertion errors in field-assembled systems, while the tape-and-reel packaging enables seamless integration into automated high-throughput SMT production lines.

Frequently Asked Questions
How many contacts does the TSM-127-03-TL-DH-A-P-TR provide, and what does the polarizing post prevent?
The TSM-127-03-TL-DH-A-P-TR carries 54 contacts across a dual-row 0.100 inch pitch layout; the polarizing post (P option) physically prevents insertion of the mating connector in the wrong orientation, eliminating reverse-polarity damage during field assembly or board bring-up.
Does the tape-and-reel format of this 54-position connector support high-volume automated assembly?
Yes. The TR suffix confirms tape-and-reel packaging, which loads directly into standard SMT pick-and-place feeders; this allows the 54-pin dual-row surface mount strip to be placed at 0.100 inch pitch with machine precision across thousands of boards per shift without manual handling.
What advantage do the through-hole locating pins provide during surface mount reflow of this connector?
Through-hole locating pins anchor the 54-position connector body mechanically to the PCB before and during reflow, preventing the part from floating or tilting on 0.100 inch pitch SMT pads when solder melts; this is critical for maintaining coplanarity on long dual-row strips in production environments.
In what procurement scenario does a designer switch from the TSM-127-03-TL-DH-A-P-TR to a non-polarized variant?
A non-polarized 54-pin variant is chosen when board space precludes the additional polarizing-post clearance zone, or when a system design uses separate mechanical keying via connector housings rather than relying on the 0.100 inch pitch header itself to enforce orientation; the trade-off is that assembly personnel must verify polarity manually.
