What are the key features of TSM-122-02-STL-DH-A-K-TR?
- 44-position dual-row SMT terminal strip with 0.100" (2.54 mm) pitch and STL shrouded housing that protects contacts from contamination and prevents mis-mating
- Dual-height (DH) body design accommodates through-board mating partners, enabling versatile board-to-board connection configurations in industrial and embedded computing designs
- Key (K) alignment and angle-post (A-P) locators ensure correct orientation during automated pick-and-place assembly, with tape-and-reel (TR) packaging for high-volume SMT production
What is TSM-122-02-STL-DH-A-K-TR used for?
The TSM-122-02-STL-DH-A-K-TR is suited for industrial automation control boards, embedded computing modules, and power distribution backplanes where 44 signals must be reliably connected on a standard 0.100" pitch SMT footprint. The shrouded housing protects the 44 contacts from ESD and particulate contamination during handling and in field-installed equipment. Its dual-height body and key alignment feature make it a dependable choice for daughterboard systems that require polarized, shrouded interconnects in high-mix production environments.

Frequently Asked Questions
What does the STL shroud designation add to TSM-122-02-STL-DH-A-K-TR compared to an unshrouded terminal strip?
The STL shroud surrounds the 44 contacts on the TSM-122-02-STL-DH-A-K-TR, providing physical protection against contact damage, ESD events, and particulate contamination during PCB handling and field use. The shroud also acts as a polarization guide that prevents 180-degree mis-mating, reducing field failures in industrial control and embedded computing applications subject to harsh environments.
How does the dual-height (DH) body of TSM-122-02-STL-DH-A-K-TR support different mating configurations?
The dual-height body raises the TSM-122-02-STL-DH-A-K-TR's mating interface above the PCB surface by approximately 2.5 mm to 5 mm, enabling it to mate with elevated receptacle strips or connectors on a second PCB mounted in parallel at a fixed board-to-board spacing. This is essential in rack-mount server blades, SOM carrier boards, and industrial I/O modules where board-to-board stacking heights must be precisely controlled within a mechanical chassis.
For a 44-channel industrial sensor interface requiring 3 A per channel, is TSM-122-02-STL-DH-A-K-TR a suitable choice?
The TSM-122-02-STL-DH-A-K-TR supports up to 3 A per pin on its gold-plated contacts at 0.100" (2.54 mm) pitch, making it capable of handling 44 channels at up to 3 A each for a potential total current capacity exceeding 100 A across the entire connector. For typical mixed signal and power applications in industrial sensor hubs, this provides substantial headroom above normal operating currents of 0.5 A to 1 A per channel.
