What are the key features of TSM-126-02-SM-DH-A-K-TR?
- 52-position dual-row terminal strip at 0.100" (2.54mm) pitch supporting high signal-count SMT board-to-board interconnect
- Double-height (DH) profile providing additional vertical clearance for stacked mezzanine PCBs and daughterboard assemblies
- Tape-and-reel (-TR) and surface mount (SM) termination optimized for automated high-volume pick-and-place PCB production
What is TSM-126-02-SM-DH-A-K-TR used for?
The TSM-126-02-SM-DH-A-K-TR is designed for 52-pin dual-row board-to-board interconnect in embedded computing systems, industrial backplane assemblies, and telecommunications line cards. Its double-height (DH) profile allows adequate clearance for components mounted between stacked PCBs in mezzanine card configurations. This connector in tape-and-reel format supports automated SMT assembly lines for high-volume production of I/O expansion modules, data acquisition boards, and processor daughterboards.

Frequently Asked Questions
What distinguishes the TSM-126-02-SM-DH-A-K-TR from the TSM-126-02-SS-DH-A-K-TR in terms of termination?
The TSM-126-02-SM-DH-A-K-TR uses an SM (surface mount) termination style, while the TSM-126-02-SS-DH-A-K-TR uses an SS (surface mount solder) style — both are surface mount variants but differ in lead or pad geometry. Both provide 52 positions at 0.100" (2.54mm) pitch with a double-height DH profile; designers should verify PCB land pattern compatibility with the specific termination footprint before selecting between the 2 variants.
For a stacked PCB system requiring 52 signals, how does the DH profile of the TSM-126-02-SM-DH-A-K-TR help?
The double-height (DH) profile of the TSM-126-02-SM-DH-A-K-TR provides increased standoff height between mated boards in a stacked PCB assembly. This extra clearance accommodates SMT or through-hole components placed between the 2 parallel boards at 0.100" (2.54mm) pitch, preventing mechanical interference in 52-pin dual-row stacked configurations used in backplane and mezzanine designs.
How does the 52-pin count of the TSM-126 series benefit industrial I/O expansion card designs?
A 52-pin dual-row connector at 0.100" (2.54mm) pitch provides enough contacts to route 48 signal lines plus 4 power or ground pins in a single SMT connector, reducing the number of connectors needed on an I/O expansion card. The TSM-126-02-SM-DH-A-K-TR's tape-and-reel format also supports automated assembly in volume production of industrial control I/O modules and data acquisition cards.
Is the TSM-126-02-SM-DH-A-K-TR suitable as a lower-cost alternative to a 60-pin connector in designs where only 52 signals are needed?
Yes, when a design requires only 52 signals, the TSM-126-02-SM-DH-A-K-TR is a natural choice over a 60-pin connector, avoiding the extra 8 unused contacts and their associated cost. At 0.100" (2.54mm) pitch with dual-row SMT termination, it also occupies less PCB area than a 60-pin single-row connector, making it efficient for space-constrained embedded computing boards.
