What are the key features of TSM-139-01-S-DV-P-TR?
- 78-position dual-row surface mount layout at 2.54 mm (0.100 inch) pitch enables high I/O density in a compact SMT footprint compatible with standard reflow soldering
- Single-ended (S) contact style with dual-row vertical (DV) orientation provides a low-profile mating interface suitable for ribbon cable and direct-wire harness applications
- Tape-and-reel (TR) packaging with polarization (P) feature supports automated pick-and-place assembly and prevents mis-orientation during high-volume PCB production
What is TSM-139-01-S-DV-P-TR used for?
The TSM-139-01-S-DV-P-TR is ideal for dense wire-to-board and cable-to-board connections in industrial control panels, embedded computing backplanes, and data acquisition front-ends requiring 78 simultaneous I/O channels. Its 2.54 mm pitch is compatible with standard 0.100 inch IDC ribbon cable housings, simplifying harness design. The tape-and-reel delivery format and polarization feature make it well suited for automated SMT lines producing large volumes of sensor interface or motor controller PCBs.

Frequently Asked Questions
How does the single-ended (S) contact style of TSM-139-01-S-DV-P-TR differ from dual-beam contacts in the same pitch family?
Single-ended contacts in the TSM series use a single wiping beam per position, providing a lower insertion force compared to dual-beam alternatives — typically under 0.5 N per pin. For a 78-position connector this keeps total mating force below 39 N, allowing hand mating without specialized tooling.
Why is the tape-and-reel (TR) format preferred over bulk packaging for the TSM-139-01-S-DV-P-TR in automated SMT assembly?
Tape-and-reel format provides consistent part orientation for pick-and-place machines, enabling placement rates exceeding 500 parts per hour without manual loading. For a 78-position connector measuring approximately 100 mm in length, consistent tape-reel orientation is critical to avoid 5 mm to 10 mm placement offsets that would misalign the dual-row contact array.
What ribbon cable pitch is compatible with the TSM-139-01-S-DV-P-TR mating interface?
The 2.54 mm (0.100 inch) contact pitch matches standard 26 AWG flat ribbon cables and IDC housings at the same pitch, which are the most widely available cable types for 78-conductor parallel interfaces. This compatibility eliminates the need for custom cable or pitch-conversion adapters.
When would a designer choose TSM-139-01-S-DV-P-TR over TSM-139-03-F-DV-P-TR for a 78-position SMT harness application?
The '01' variant uses single-ended (S) contacts optimized for low-force cable mating at under 0.5 N per pin, while the '03' variant uses a female (F) contact style. The S contact is preferred when mating a rigid pin header at 2.54 mm pitch, whereas the F style targets receptacle-to-receptacle or floating-wire termination, making the '01' the correct choice for standard IDC ribbon harnesses.
