What are the key features of SMH-121-02-TM-S-TR?
- 21-position single-row layout on 0.100 inch (2.54 mm) pitch for standard through-hole and SMT compatibility
- Horizontal orientation enables low-profile mating perpendicular to PCB surface for space-constrained designs
- Gold-plated socket contacts provide reliable, low-resistance connections over repeated mating cycles
- Tape-and-reel packaging (TR) supports high-volume automated SMT pick-and-place assembly
- Compatible with SAMTEC TSW and SHF series header strips for verified mating pairs
What is SMH-121-02-TM-S-TR used for?
The SMH-121-02-TM-S-TR is used in consumer electronics, industrial control boards, and embedded computing systems requiring compact horizontal socket connections at 0.100 inch pitch. Its 21-position single-row format suits backplane edge connections, daughtercard interfaces, and cable-to-board assemblies where a low-profile horizontal mating angle saves vertical clearance. The tape-and-reel packaging enables seamless integration into high-volume automated SMT production lines.

Frequently Asked Questions
What pitch and position count does the SMH-121-02-TM-S-TR provide for board interconnects?
The SMH-121-02-TM-S-TR offers 21 single-row positions on a 0.100 inch (2.54 mm) pitch, yielding 21 total contacts in a horizontal surface-mount socket configuration suitable for standard PCB interconnect applications.
How does the horizontal mating orientation of SMH-121-02-TM-S-TR benefit low-profile PCB designs?
The horizontal surface-mount orientation allows mating headers to connect parallel to the PCB plane, reducing the required vertical clearance to under 5 mm, which is critical in enclosures with tight height restrictions such as handheld devices or shallow rackmount equipment.
Which SAMTEC header series mates with the SMH-121-02-TM-S-TR socket strip?
The SMH-121-02-TM-S-TR mates with SAMTEC TSW and SHF series header strips on the same 0.100 inch (2.54 mm) pitch, providing a verified mating pair rated for dozens of insertion and extraction cycles without significant contact wear.
Is SMH-121-02-TM-S-TR suitable for automated high-volume PCB assembly lines?
Yes, the TR (tape-and-reel) packaging of the SMH-121-02-TM-S-TR supports automated SMT pick-and-place equipment at standard reel dimensions, enabling throughput of thousands of parts per hour in high-volume electronics manufacturing environments operating at up to 260°C reflow temperatures.
