Applications
The TSM-143-02-SS-DV-P-TR is used in industrial automation, embedded computing, and test and measurement equipment where high-pin-count 2.54 mm pitch SMT terminal strips with stainless steel contacts are required for reliability. Its 86-position dual-row configuration supports dense multi-signal board interconnects on backplane and mezzanine assemblies. Tape-and-reel packaging makes it well-suited for automated high-volume PCB assembly environments.

Frequently Asked Questions
What stainless steel contact advantage does TSM-143-02-SS-DV-P-TR offer over tin-plated TSM variants in humid environments?
Stainless steel contacts in the TSM-143-02-SS-DV-P-TR resist oxidation and corrosion far better than standard tin-plated contacts when exposed to humidity or mild chemical environments. This makes the SS variant preferable for outdoor industrial enclosures, marine electronics, and factory floor equipment where tin contacts might develop oxide layers that increase contact resistance over time. The connector still provides 0.50 A per pin capacity and operates within the standard 2.54 mm pitch 86-position SMT platform.
For an 86-signal industrial backplane, how does the dual-row TSM-143-02-SS-DV-P-TR reduce board area versus two single-row connectors?
The 86-position dual-row TSM-143-02-SS-DV-P-TR consolidates 43 signal pairs into a single SMT footprint at 2.54 mm pitch, which requires approximately half the board edge length compared to using two separate 43-position single-row connectors. Reducing connector count from 2 to 1 also simplifies PCB routing, decreases bill of materials line items, and cuts assembly placement time in automated SMT production by eliminating a second pick-and-place step.
Is TSM-143-02-SS-DV-P-TR compatible with standard 2.54 mm pitch footprints and PCB libraries?
Yes. The TSM-143-02-SS-DV-P-TR uses the industry-standard 2.54 mm (0.100 inch) pitch in a dual-row SMT configuration that matches common PCB CAD library footprints for 0.100 inch SMT terminal strips. This means engineers can drop the part directly into existing board layouts without custom footprint creation. The 86-position count sets the total connector body length, and the tape-and-reel format ensures pick-and-place compatibility with standard SMT assembly programs.
What current and temperature ratings govern the TSM-143-02-SS-DV-P-TR in a continuous industrial duty application?
Each of the 86 positions in the TSM-143-02-SS-DV-P-TR is rated for 0.50 A continuous current, and the connector is specified for an operating temperature range up to 125°C. These ratings are consistent with SAMTEC TSM series specifications and make the connector appropriate for digital signal lines and low-power supply connections in industrial control panels, embedded system boards, and test equipment operating in elevated-temperature environments.
