What are the key features of TSM-126-02-TM-DH-A-K-TR?
- 52-position dual-row surface mount terminal strip at 0.100" (2.54 mm) pitch supports high signal counts in standard pitch board-to-board and wire-to-board interconnects
- Through-mated (TM) tail design provides mechanical interlock and reliable electrical contact during mating and under vibration
- Tape-and-reel (TR) packaging enables automated pick-and-place assembly for efficient high-volume PCB manufacturing
- Double-height (DH) mating socket clearance accommodates taller mating connectors, increasing layout flexibility in dense board assemblies
What is TSM-126-02-TM-DH-A-K-TR used for?
The TSM-126-02-TM-DH-A-K-TR is used in embedded control systems, industrial automation boards, and test-and-measurement equipment where 52 signals must be routed reliably between PCB assemblies at standard 0.100" pitch. Its dual-row layout reduces connector length compared to single-row alternatives, conserving board edge space in compact controller designs. The tape-and-reel format supports high-throughput SMT manufacturing for IoT gateways and communications equipment.

Frequently Asked Questions
What is the pin count and row configuration of the TSM-126-02-TM-DH-A-K-TR?
The TSM-126-02-TM-DH-A-K-TR provides 52 total positions in a dual-row arrangement at 0.100" (2.54 mm) pitch, with 26 contacts per row. This dual-row layout halves the connector body length compared to a single-row 52-position strip, conserving PCB edge space in industrial controller and embedded computing designs.
How does the through-mated TM tail design improve connector reliability under vibration?
The through-mated (TM) tail design creates a mechanical interlock between the terminal strip and its mating receptacle, preventing axial pullout under vibration and mechanical shock. This is important in industrial automation equipment, robotics, and vehicle-mounted electronics where connectors may be subjected to acceleration loads of 5 G to 50 G across the 0.100" (2.54 mm) pitch interface.
For an industrial controller design, when would TSM-126-02-TM-DH-A-K-TR be preferred over a 0.050" pitch alternative?
The 0.100" (2.54 mm) pitch is preferred when signals carry currents above 1 A per contact, when field technicians need to manually mate connectors without precision tooling, or when the PCB cost savings from 0.050" pitch routing do not justify the tighter manufacturing tolerances. The TSM series 0.100" pitch is the standard choice for 24 V I/O, relay control, and sensor wiring in industrial controllers where robustness outweighs density.
What reflow temperature profile is compatible with the TSM-126-02-TM-DH-A-K-TR for SMT assembly?
SAMTEC TSM series surface mount terminal strips are designed for standard SMT reflow soldering with a peak temperature of 260°C for 30 seconds, compliant with IPC/JEDEC J-STD-020 MSL requirements. The tape-and-reel packaging maintains component orientation and coplanarity during handling, ensuring accurate placement on automated lines running at board throughput rates of 500 to 2000 panels per hour.
