What are the key features of TSM-114-04-L-DH-A-K-TR?
- 28-position dual-row .100" (2.54 mm) pitch SMT terminal strip with shrouded housing for mechanical keying and contact protection
- Low-profile horizontal (L) lead style enables automated surface mount reflow assembly with compatibility to standard SMT paste-and-reflow processes at up to 260°C
- Tape-and-reel (-TR) packaging supports high-speed automated pick-and-place for production volumes exceeding 1,000 units per run
What is TSM-114-04-L-DH-A-K-TR used for?
The TSM-114-04-L-DH-A-K-TR is suited for dual-row 28-pin board-to-board and wire-to-board interconnects in industrial automation, embedded computing, and communication modules that require a shrouded SMT terminal strip at 2.54 mm pitch. Its horizontal lead profile keeps the connector height low, making it compatible with enclosures and PCB stacks where vertical clearance is limited to a few millimeters. The shrouded dual-row housing prevents mis-mating in environments with multiple adjacent connectors on the same PCB.

Frequently Asked Questions
What is the position count and row arrangement of the TSM-114-04-L-DH-A-K-TR?
The TSM-114-04-L-DH-A-K-TR has 28 positions arranged in a dual-row format with 14 positions per row at a .100 inch (2.54 mm) pitch. This dual-row layout allows 28 signals or power connections to be routed through a single connector body with a smaller PCB footprint than two separate 14-position single-row strips.
What does the shrouded housing (DH) add to the TSM-114-04-L-DH-A-K-TR compared to an unshrouded version?
The DH (dual-row shrouded housing) surrounds all 28 contacts with a plastic shell that provides mechanical keying to prevent reverse or offset mating errors during assembly and field servicing. The shroud also physically protects the contact pins from damage during PCB handling and shipping, and helps align the mating connector for repeatable low-insertion-force engagement.
Can the TSM-114-04-L-DH-A-K-TR be assembled using automated surface mount equipment?
Yes, the -TR suffix indicates tape-and-reel packaging compatible with standard pick-and-place machines, and the L (horizontal) lead style is designed for surface mount reflow soldering at peak temperatures up to 260°C. Together, these features allow fully automated PCB assembly without manual connector placement, reducing labor cost and placement error rates in production runs of thousands of units.
When is the TSM-114-04-L-DH-A-K-TR a better choice than a through-hole terminal strip of equivalent pin count?
An SMT terminal strip is preferred over through-hole when the PCB design uses single-sided component assembly or when board thickness is less than 1.6 mm, making plated through-holes impractical. The TSM-114-04-L-DH-A-K-TR eliminates drilling for 28 through-holes, saving PCB manufacturing time and allowing routing of traces in the via-cleared area beneath the connector footprint.
