What are the key features of TSM-139-04-STL-DV-P-TR?
- 78 positions in a dual-row 0.100-inch (2.54 mm) pitch layout provides maximum signal density for board-to-board interconnects
- Surface-mount termination with tape-and-reel (TR) packaging enables automated pick-and-place assembly for high-volume production
- Terminal strip form factor with P-series (press-fit compatible) contact retention ensures reliable connections in vibration-prone environments
What is TSM-139-04-STL-DV-P-TR used for?
The TSM-139-04-STL-DV-P-TR is used in industrial control backplanes, test and measurement interfaces, and embedded computing daughter-card connections where 78 signals must be reliably routed across a standard 0.100-inch pitch interface. Its surface-mount design and tape-and-reel format support automated assembly on high-volume production boards in telecommunications, robotics, and data acquisition systems.

Frequently Asked Questions
What is the position count and pitch of the TSM-139-04-STL-DV-P-TR terminal strip?
The TSM-139-04-STL-DV-P-TR has 78 total positions arranged in 2 rows of 39 contacts on a standard 0.100-inch (2.54 mm) pitch. This configuration allows routing of up to 39 signals per row, making it suitable for high-density bus interfaces on industrial control and embedded computing boards.
How does the surface-mount design of the TSM-139 series simplify PCB assembly compared to through-hole alternatives?
The surface-mount termination eliminates the need for drilling 78 through-holes in the PCB, reducing board manufacturing cost and allowing the connector to be placed on both sides of the board. The tape-and-reel format supports pick-and-place machines running at 5000 or more placements per hour, which is critical for reducing assembly time in high-volume production.
What current rating per contact does the TSM series support, and for what signal types is it appropriate?
SAMTEC TSM series contacts are typically rated for up to 3 A per pin at 30 VAC/DC, making them suitable for power distribution alongside signal routing on the same 78-position connector. This dual-purpose capability allows system designers to eliminate separate power connectors on backplanes that carry both logic signals and low-current power rails.
In which industrial or computing board-to-board applications is the TSM-139-04-STL-DV-P-TR most commonly used?
This terminal strip is commonly found in PLC backplane bus interfaces, SBC (single-board computer) expansion slots, and test fixture motherboard sockets where 78-pin 0.100-inch pitch connectivity is a standard interface. The P-series contact press-fit option also supports insertion into plated through-holes for mixed SMT/press-fit assembly strategies used in telecom line cards and industrial I/O modules.
