What are the key features of TSM-126-02-S-DH-A-K-TR?
- 52-position dual-row SMT terminal strip at 0.100" pitch providing 104 total contacts for medium-to-high pin-count board interfaces
- Keyed (K) polarization prevents incorrect connector orientation during mating, reducing assembly errors in multi-connector boards
- Dual-height (DH) body accommodates varied board-to-board stacking clearances in modular PCB system designs
- Tape-and-reel (TR) packaging supports automated SMT pick-and-place assembly for consistent high-volume production
What is TSM-126-02-S-DH-A-K-TR used for?
The TSM-126-02-S-DH-A-K-TR is well suited for medium-to-high pin-count board-to-board and module interconnects in embedded computing, industrial I/O systems, and data acquisition platforms where 104 contacts at 0.100" pitch provide sufficient signal routing bandwidth. Its keyed design prevents misorientation during PCB assembly or field servicing, making it especially valuable in multi-connector systems where incorrect mating could cause damage. The dual-height body and tape-and-reel packaging further support modular system integration and automated SMT manufacturing workflows.

Frequently Asked Questions
What is the total contact count and pitch of the TSM-126-02-S-DH-A-K-TR?
The TSM-126-02-S-DH-A-K-TR is a 52-position dual-row connector providing 104 total contacts at 0.100" (2.54 mm) pitch, suitable for medium-to-high density board interconnects in industrial and embedded computing applications.
How does the K (keyed) feature of the TSM-126-02-S-DH-A-K-TR prevent assembly errors?
The K suffix designates a keyed polarization feature that physically prevents incorrect connector mating orientation; in multi-connector PCB assemblies where adjacent connectors share the same pitch and row count, keying ensures each connector mates only with its designated counterpart, preventing 104-contact mating accidents that could damage components or PCB traces.
Which board-to-board stacking configurations benefit most from the dual-height body of the TSM-126-02-S-DH-A-K-TR?
The DH (dual-height) body is most beneficial in stacked PCB assemblies where components or thermal hardware between boards require several additional millimeters of inter-board clearance beyond what a standard-height 0.100" connector provides, such as in backplane systems with heatsinks or cable harnesses routed between layers.
Can the TSM-126-02-S-DH-A-K-TR be used in automated SMT production, and what packaging does it come in?
Yes, the TR suffix confirms tape-and-reel packaging compatible with standard automated SMT pick-and-place machines; the surface mount termination is designed for reflow soldering at lead-free profiles up to 260°C peak, and the 52-position dual-row footprint is supported by standard PCB CAD libraries for rapid design integration.
