Key Features
- 52 total positions in a dual-row 0.100" (2.54 mm) pitch configuration
- High-profile mounting (H suffix) provides increased connector height for component clearance
- Polarized keying (P suffix) ensures correct insertion orientation and prevents mating errors
- Gold-plated contacts for low contact resistance below 20 milliohms and corrosion resistance
- Tape-and-reel packaging for automated high-volume pick-and-place assembly
- Surface mount termination supports standard SMT reflow profiles up to 260°C
Applications
The TSM-126-01-H-DH-A-P-TR is used in dense board-to-board interconnect designs that require 52 signal positions with a high-profile mounting height to accommodate tall components underneath the connector body. It is commonly specified in industrial backplane systems, embedded computing carrier boards, and modular communication equipment where correct mating orientation is enforced by the polarized key and tall component clearance is needed on the mating board.

Frequently Asked Questions
What does the H suffix in TSM-126-01-H-DH-A-P-TR indicate, and when should a high-profile mount be specified over a standard mount?
The H suffix designates a high-profile mounting style, which increases the connector's above-board height to provide clearance for taller components located on the mating PCB directly beneath the connector area. High-profile mounting is specified when components such as capacitors, inductors, or discrete ICs exceeding 3 mm in height are placed within the connector's footprint shadow on the opposing board.
How many signal positions does the TSM-126-01-H-DH-A-P-TR accommodate, and at what pin pitch?
The TSM-126-01-H-DH-A-P-TR provides 52 total positions arranged in 2 rows of 26 contacts each on a standard 0.100" (2.54 mm) pitch. This dual-row layout routes up to 52 independent signals through a single SMT connector, reducing board-edge space requirements compared to two separate 26-position single-row strips while maintaining 0.1" grid compatibility.
Why does the TSM-126-01-H-DH-A-P-TR include polarized keying, and how does it protect a 52-pin circuit from incorrect mating?
The P suffix polarized key is a mechanical feature that physically prevents the 52-position connector from mating in the reversed orientation. Without polarization, a reversed insertion on a 52-pin bus carrying mixed 3.3 V, 5 V, and ground lines could apply supply voltages to ground pins or data lines, immediately damaging ICs connected to those 52 signals on both boards.
Which procurement format is recommended for the TSM-126-01-H-DH-A-P-TR in a production environment, and what does the TR suffix mean?
The TR suffix specifies tape-and-reel packaging, which is the standard procurement format for production environments using automated SMT assembly. The 52-position, 0.100" pitch connector is delivered on a continuous reel, enabling direct feeder loading into pick-and-place machines and eliminating manual connector placement for quantities above 500 pieces per run.
