TSM-144-01-STL-DV-P-TR SAMTEC Connector (Other) In Stock
TSM-144-01-STL-DV-P-TR is an 88-position dual-row surface-mount terminal strip from Samtec with a 2.54 mm (0.100") pitch, gold-plated contacts rated at 3 A per pin and 125 V AC/DC, and a shrouded low-profile STL body with tape-and-reel packaging for automated assembly. The shroud prevents mismating with incompatible connectors, making it suited for backplane and industrial daughter-card designs. Available from authorized global distributors with worldwide shipping.

What are the key features of TSM-144-01-STL-DV-P-TR?
- 88-position dual-row SMT layout at 2.54 mm (0.100") pitch with STL shrouded body for polarized, mismating-protected board-to-board connections
- Gold-plated contacts rated 3 A per pin and 125 V AC/DC provide reliable low-resistance signal and power routing in a single connector body
- Tape-and-reel (TR) packaging enables high-throughput automated SMT assembly compatible with lead-free SAC305 reflow profiles up to 260°C
What is TSM-144-01-STL-DV-P-TR used for?
The TSM-144-01-STL-DV-P-TR is well-suited for industrial control backplanes, embedded computing expansion cards, and modular test-and-measurement systems where mismating prevention is essential during field assembly or maintenance. The shrouded body guides the mating socket into the correct orientation, eliminating reversed-insertion failures in multi-board rack systems with limited visibility. Its 88 pins at 2.54 mm pitch handle combined power-and-signal routing across a single 112 mm strip, reducing connector count and assembly complexity.

Frequently Asked Questions
What is the physical layout of the 88 contacts in the TSM-144-01-STL-DV-P-TR and how long is the connector body?
The 88 contacts are arranged as 2 rows of 44 positions each at a 2.54 mm (0.100") pitch, forming a total strip length of approximately 44 × 2.54 mm = 112 mm. The dual-row vertical SMT (DV) termination style means both rows share a single SMT solder-tail pass through a lead-free reflow oven, eliminating the need for wave-soldering or selective soldering that through-hole equivalents would require.
What does the STL shroud designation add compared to a standard unshrouded TSM-144 connector?
The STL suffix adds a polarizing shroud that physically encloses the pin field and incorporates a keying wall, reducing the risk of off-by-one mating errors when a 44-position row is adjacent to another connector on the same backplane. The shroud holds the mating socket aligned during blind-mate insertion, which is important in rack-mount systems where an assembler cannot directly see the connector pair. This feature comes at the cost of a slightly taller above-board body height compared to the unshrouded TM variant.
How much current can each contact in the TSM-144-01-STL-DV-P-TR carry, and can the connector handle both supply and signal pins simultaneously?
Each contact is rated for 3 A continuous current and 125 V AC/DC working voltage, with gold-plated contact resistance below 20 mΩ. In a mixed-use configuration, designers commonly assign 4 pins for a 3.3 V supply rail carrying up to 12 A aggregate, 4 pins for a 5 V rail, and use the remaining 80 pins for digital signals. This approach consolidates power and signal distribution in one 112 mm connector instead of using separate power headers.
Which Samtec socket series mate correctly with the TSM-144-01-STL-DV-P-TR?
The TSM-144 shrouded pin strip mates with Samtec SSW-144, ESW-144, and BCS-144 dual-row socket strips, with the mating socket requiring a housing compatible with the STL shroud geometry. The 44-position-per-row count and 2.54 mm pitch are also dimensionally compatible with many standard 0.100" dual-row female header families from other manufacturers, provided their housings clear the shroud wall. Samtec's online ECAD library provides 3D STEP models to verify clearance before ordering prototype quantities.
For a modular industrial I/O card system that requires hot-swap-safe insertion, how does the TSM-144-01-STL-DV-P-TR address this need?
The STL shroud provides guided insertion with controlled engagement that prevents pin skew damage during blind-mate hot-swap scenarios. Coupling the TSM-144-01-STL-DV-P-TR with power-first mating sockets that have staggered pin lengths ensures ground and power pins engage 1 mm to 2 mm before signal pins, satisfying hot-swap sequencing requirements common in IEC 61131-based modular PLC backplane standards. The 3 A per pin rating and low contact resistance ensure that power-rail bounce during card insertion stays below 50 mV in a well-decoupled design.
