What are the key features of TSM-126-01-SM-DH-A-K-TR?
- 52-position dual-row layout at 0.100-inch (2.54 mm) pitch covering broad I/O and power distribution needs
- Shorting (SM) bar option enables jumper-selectable circuit configuration directly at the connector
- 3 A per pin current rating supporting mixed signal and power rails across all 52 positions
- Tape-and-reel (TR) delivery for automated high-volume SMT pick-and-place manufacturing lines
What is TSM-126-01-SM-DH-A-K-TR used for?
The TSM-126-01-SM-DH-A-K-TR is suited for backplane interconnect, industrial control boards, and embedded computing platforms needing 52-position dual-row connectivity at the universal 2.54 mm pitch. The shorting bar capability allows hardware-selectable configuration options on the PCB, making it valuable in programmable logic controllers and development kits where multiple operating modes must be user-selectable without firmware changes. Its surface-mount design and tape-and-reel packaging integrate smoothly into modern automated SMT production environments.

Frequently Asked Questions
What is the purpose of the shorting (SM) bar designation in TSM-126-01-SM-DH-A-K-TR?
The SM designation indicates the connector includes a shorting bar that bridges adjacent pins to create a closed circuit by default. This allows 52-position boards to implement jumper-selectable configuration options such as boot mode selection, voltage level selection, or address setting without additional discrete jumper components, simplifying PCB design for systems offering multiple operating modes.
How many positions and at what pitch is the TSM-126-01-SM-DH-A-K-TR, and what current does each pin support?
The TSM-126-01-SM-DH-A-K-TR has 52 positions arranged in a dual-row configuration at 0.100-inch (2.54 mm) pitch. Each pin supports up to 3 A of continuous current, giving a total capacity of 156 A across all pins, suitable for both high-density signal routing and auxiliary power distribution in industrial or embedded systems.
When would a designer choose the 52-position TSM-126 over a 30-position TSM-115 for a backplane application?
Designers select the 52-position TSM-126-01-SM-DH-A-K-TR over the 30-position TSM-115 when the application requires more than 30 signal or power lines on a single connector, such as in backplane designs integrating CPU buses, power rails at 3.3 V and 5 V, and control signals simultaneously. The additional 22 positions at the same 2.54 mm pitch accommodate expanded I/O without switching to a non-standard pitch.
Is the TSM-126-01-SM-DH-A-K-TR suitable for tape-and-reel SMT assembly in high-volume production?
Yes, the -TR suffix confirms tape-and-reel packaging fully compatible with automated pick-and-place equipment. The 2.54 mm pitch surface-mount pads follow IPC-7351 land pattern standards, and the connector withstands reflow solder peak temperatures of 260°C, making it suitable for lead-free SAC305 reflow processes in high-volume PCB manufacturing.
