What are the key features of TSM-131-01-SM-DH-A-K-TR?
- 62 positions on 2.54 mm (0.100 inch) pitch dual-row SMT layout for maximum signal density
- Friction-lock keying (K option) prevents mis-mating and secures connector engagement in multi-connector assemblies
- Tape-and-reel (TR) packaging enables automated pick-and-place in high-volume SMT production lines
What is TSM-131-01-SM-DH-A-K-TR used for?
The TSM-131-01-SM-DH-A-K-TR is used in high-pin-count backplane interconnects, industrial computer expansion cards, and modular embedded systems requiring a 62-pin, 2.54 mm pitch surface-mount interface. Its dual-row configuration accommodates mixed signal, power, and ground contacts within a compact footprint suitable for rack-mount and compact PCB designs. The tape-and-reel format supports efficient automated assembly in volume manufacturing.

Frequently Asked Questions
How many contacts does the TSM-131-01-SM-DH-A-K-TR provide and at what pitch?
The TSM-131-01-SM-DH-A-K-TR provides 62 contacts arranged in a dual-row layout on a 2.54 mm (0.100 inch) pitch, with 31 positions per row. Each contact supports up to 3 A, accommodating both signal and moderate power distribution on a single connector.
How does the friction-lock keying on TSM-131-01-SM-DH-A-K-TR improve assembly reliability?
The K keying option includes a physical polarization feature that blocks mating with incorrectly oriented or non-keyed connectors. In boards with multiple 62-pin connectors close together, this prevents costly mis-mating errors that could damage 3.3 V or 5 V power circuits during field installation or maintenance.
For a 62-pin expansion bus, how does TSM-131-01-SM-DH-A-K-TR compare to a through-hole equivalent?
Compared to a through-hole 62-pin header, the TSM-131-01-SM-DH-A-K-TR eliminates the need for drilled vias, saving board layers and reducing PCB fabrication cost. Its SMT pads also allow placement on either board side, and the reflow-compatible design handles peak soldering temperatures of 260°C without special tooling.
What mating connectors are compatible with TSM-131-01-SM-DH-A-K-TR?
SAMTEC TSW-131 and SSW-131 series 62-pin dual-row through-hole or SMT headers on 2.54 mm pitch are standard mating partners. Board-stacking height can be adjusted from approximately 8.5 mm to 20 mm by selecting different mating header stack heights, providing design flexibility for compact embedded modules and larger backplane systems.
