What are the key features of TSM-127-01-L-DH-A-K-TR?
- 54-position dual-row surface mount terminal strip with 0.100 inch (2.54 mm) pitch for high-density connector applications
- Gold-plated brass contacts providing low contact resistance and excellent corrosion resistance for reliable signal integrity
- Tape-and-reel packaging (-TR suffix) enabling automated pick-and-place assembly for high-volume PCB production
What is TSM-127-01-L-DH-A-K-TR used for?
The TSM-127-01-L-DH-A-K-TR is well suited for board-to-board and board-to-wire interconnect in industrial control systems, test equipment, and embedded computing platforms. Its 54-position dual-row layout makes it ideal for high-density signal routing in server backplanes and data acquisition modules. The tape-and-reel packaging supports automated SMT assembly lines, reducing hand-placement costs in high-volume production.

Frequently Asked Questions
What is the contact pitch of the TSM-127-01-L-DH-A-K-TR and how does it affect PCB layout density?
The TSM-127-01-L-DH-A-K-TR uses a 0.100 inch (2.54 mm) pitch between contacts. With 54 positions arranged in a dual-row configuration, this connector occupies approximately 68.58 mm of board length, offering a familiar standard pitch that simplifies routing while maintaining a high pin count for signal-intensive designs.
Which assembly process is supported by the TSM-127-01-L-DH-A-K-TR tape-and-reel format?
The -TR suffix indicates tape-and-reel packaging, which supports fully automated SMT pick-and-place assembly. This reduces manual handling errors, supports production rates of hundreds of components per hour, and is compatible with standard 8 mm or 12 mm carrier tape feeders used in most surface mount production lines.
When would a designer choose the TSM-127-01-L-DH-A-K-TR over a through-hole terminal strip of similar pitch?
A designer should choose the TSM-127-01-L-DH-A-K-TR when the PCB must be soldered using a reflow oven rather than wave soldering, saving at least 1 assembly step. The SMT footprint also allows component placement on both sides of a board, reducing overall PCB area by up to 30% compared to through-hole alternatives in multi-layer designs.
