What are the key features of TSM-125-01-S-DH-A-K-TR?
- 50-position single-row at 0.100-inch (2.54 mm) pitch provides a high contact count in a compact single-row SMT strip footprint
- Dual-height (DH) insulator raises the mating plane to clear tall components on the opposing board, giving several millimeters of headroom flexibility
- Keying (K suffix) physically prevents incorrect connector orientation across all 50 positions, eliminating mis-mate risk in densely populated assemblies
What is TSM-125-01-S-DH-A-K-TR used for?
The TSM-125-01-S-DH-A-K-TR is ideal for single-row 50-signal interfaces in evaluation boards, backplane-to-module connectors, and industrial I/O breakout cards where standard 0.100-inch pitch SMT termination is preferred. The dual-height insulator allows capacitors and resistors taller than 2 mm on the mating board to fit without interference, simplifying multi-board stack design. Keying and tape-and-reel packaging make it straightforward to deploy reliably in both prototype and production environments.

Frequently Asked Questions
How many positions and what row configuration does TSM-125-01-S-DH-A-K-TR use at its standard 0.100-inch pitch?
The TSM-125-01-S-DH-A-K-TR is a 50-position, single-row (S) terminal strip at 0.100-inch (2.54 mm) pitch, spanning approximately 4.9 inches of board edge. The single-row format keeps the connector narrow, which is useful in tight card-edge or parallel-bus layouts where width is constrained but 50 signals must be routed.
How does the dual-height (DH) insulator in TSM-125-01-S-DH-A-K-TR benefit a stacked board design with tall passive components?
The DH insulator of the TSM-125-01-S-DH-A-K-TR provides a raised mating surface that creates several millimeters of clearance between the two mated PCBs. This allows electrolytic capacitors, power inductors, or DC-DC modules taller than 3 mm to sit on the lower board without colliding with the upper board, removing the need to reroute those components to a non-stacked area.
When should a designer choose TSM-125-01-S-DH-A-K-TR over the dual-row TSM-123-03-T-DH-A-K-TR for a 50-signal interface?
TSM-125-01-S-DH-A-K-TR in single-row (S) format is preferable when PCB width is limited but PCB length is available, since routing 50 contacts in a single line at 0.100-inch pitch occupies roughly 4.9 inches of length but only 1 row of width. The dual-row TSM-123 fits 46 contacts across two rows in about half the length, which suits width-unconstrained designs. Choose the single-row variant when narrow-width backplane slots or card-edge constraints prevent a 2-row footprint.
