What are the key features of TSM-126-01-TM-DH-A-K-TR?
- 52-position 0.100" pitch SMT terminal strip with dual-height (DH) body for enhanced mechanical stability on PCB
- Polarization keying (K option) prevents incorrect connector mating, reducing assembly errors in production
- Tape-and-reel (-TR) packaging enables automated SMT pick-and-place assembly in high-volume manufacturing
What is TSM-126-01-TM-DH-A-K-TR used for?
The TSM-126-01-TM-DH-A-K-TR is designed for surface mount interconnect in embedded computing boards, test and measurement instruments, and industrial automation systems where 52-position signal routing with keyed mating is essential. Its dual-height body provides a larger contact area and improved retention force compared to standard height variants. The keying option ensures correct polarity during field servicing and board-level replacement operations.

Frequently Asked Questions
What does the keying (K) option on TSM-126-01-TM-DH-A-K-TR accomplish during assembly?
The K (keying) option on the TSM-126-01-TM-DH-A-K-TR adds a mechanical polarization feature that physically prevents the mating connector from being inserted in the wrong orientation. In a 52-position 2.54 mm pitch connector, an incorrect insertion could damage up to 52 signal lines simultaneously, so keying is critical in production environments where connectors are installed by operators under time pressure.
How does the dual-height (DH) body of TSM-126-01-TM-DH-A-K-TR improve PCB retention compared to standard height versions?
The dual-height (DH) body design of the TSM-126-01-TM-DH-A-K-TR increases the connector body height above the PCB surface, providing a larger bearing area for the mating connector and improving pull-out force resistance. This is beneficial in applications subject to mechanical vibration, such as industrial motor drives or transportation electronics, where a standard 0.100" SMT strip might disengage under repeated shock loads.
For which board-to-board or board-to-cable use cases is TSM-126-01-TM-DH-A-K-TR a preferred choice over through-hole terminal strips?
The TSM-126-01-TM-DH-A-K-TR is preferred over through-hole variants in automated SMT-only production lines where drilling and wave-soldering steps are eliminated, reducing manufacturing cost per board. With 52 positions at 2.54 mm pitch, it supports dense signal buses on embedded single-board computers, FPGA breakout cards, and data acquisition modules while the -TR tape-and-reel format supports throughput of thousands of units per reel.
