Key Features
- 52-position dual-row SMT terminal strip on 0.100" (2.54 mm) pitch for standard PCB grid compatibility
- High-profile (H) standoff variant provides clearance for underlying PCB components beneath the connector
- Keying (K) option prevents connector mis-insertion in multi-row board assemblies
- Tape-and-reel (TR) packaging enables high-speed automated pick-and-place SMT assembly
Applications
The TSM-126-03-H-DH-A-K-TR suits applications requiring 52-position high-density interconnects on standard 0.100" pitch grids, such as industrial backplanes, test and measurement equipment, and embedded controller boards. The high-profile standoff variant allows routing of other components beneath the connector body, maximizing PCB real estate. Keying prevents assembly errors in systems with multiple adjacent headers during automated or manual board build.

Frequently Asked Questions
What does the high-profile (H) standoff option mean for the TSM-126-03-H-DH-A-K-TR in PCB layout?
The H suffix indicates an elevated standoff height above the PCB surface, typically providing several millimeters of clearance beneath the 52-position connector body. This allows passive components or traces to be routed underneath the connector, making it valuable in dense PCB layouts where every square millimeter counts.
How does the keying feature on the TSM-126-03-H-DH-A-K-TR reduce assembly errors?
The K (keying) suffix adds a mechanical polarization key that physically prevents mating with an unkeyed or differently keyed connector, avoiding costly mis-insertion on 52-pin, 0.100" pitch dual-row boards where pin 1 orientation can be ambiguous during manual or automated assembly.
Which production processes are supported by the TSM-126-03-H-DH-A-K-TR tape-and-reel format?
Packaged in tape-and-reel (TR), the TSM-126-03-H-DH-A-K-TR is compatible with standard SMT pick-and-place machines and reflow ovens used in high-volume electronics manufacturing, supporting throughput rates of hundreds of placements per minute at lead-free reflow temperatures up to approximately 260°C.
