Key Features
- 74-position dual-row 0.100" pitch SMT terminal strip for high-count signal and mixed-power distribution on a single connector
- Dual-row layout halves the connector strip length versus a single-row 74-pin alternative, conserving critical PCB board edge space
- Surface mount termination supports automated pick-and-place and standard lead-free reflow assembly up to 260°C
Applications
The TSM-137-02-LM-DV-P-TR is used in embedded computing backplanes, industrial I/O expansion modules, and evaluation boards where up to 74 signals must pass through a single compact dual-row header. Its 0.100" pitch is compatible with industry-standard IDC ribbon cable assemblies, enabling straightforward wiring to off-board peripherals and panel controls. System designers also use it in prototype rigs and test jigs requiring a large-count, low-profile SMT connector that accommodates both power and signal contacts in one footprint.

Frequently Asked Questions
How many signals can TSM-137-02-LM-DV-P-TR route, and what pitch enables standard IDC cable compatibility?
The TSM-137-02-LM-DV-P-TR provides 74 contact positions arranged in 2 rows of 37 at a 0.100" (2.54 mm) pitch. The 0.100" pitch directly matches standard 74-conductor IDC ribbon cable assemblies, allowing field wiring teams to use off-the-shelf crimp tools and flat cables without any custom cable adaptation.
For a backplane with 74 I/O lines, how does the dual-row TSM-137-02-LM-DV-P-TR reduce connector strip length compared to a single-row option?
Placing 74 positions in a dual-row 0.100" pitch configuration results in a strip length of approximately 94 mm (37 positions per row at 2.54 mm), whereas a single-row 74-pin strip at the same pitch would span about 188 mm. Halving the strip length preserves PCB edge real estate and simplifies routing on tight backplane layouts where multiple connectors share a single board edge.
What current per contact is the TSM-137-02-LM-DV-P-TR rated for when used to carry 5 V power alongside signal lines?
SAMTEC TSM series connectors at 0.100" pitch are typically rated for up to 3 A per contact. In a 74-position dual-row strip, dedicated power contacts can carry 3 A each at 5 V, 12 V, or 24 V rails, while signal contacts carry standard logic levels at milliamp-level currents, making mixed power-and-signal use in a single TSM-137-02-LM-DV-P-TR practical for backplane power distribution.
