Key Features
- 14-position SMT terminal strip with 0.100" (2.54 mm) pitch and dual-row horizontal (DH) mating orientation for low-profile cable-to-board connections
- Alignment key (K suffix) provides polarization to prevent incorrect mating orientation across all 14 positions in field assembly
- Tape-and-reel (TR) format enabling high-speed automated pick-and-place and reflow soldering in volume PCB production
Applications
The TSM-107-03-SM-DH-A-K-TR is ideal for low-profile cable-to-board and board-to-board connections in embedded control systems, consumer electronics, and industrial sensing modules that require 14 signal lines at 0.100" pitch. The horizontal dual-row mating profile keeps the connected cable running parallel to the PCB, which is beneficial in flat, thin-profile enclosure designs where vertical cable exit would cause assembly interference. The alignment key and tape-and-reel packaging ensure reliable mating orientation and efficient automated assembly in volume manufacturing.

Frequently Asked Questions
What does dual-row horizontal (DH) mating mean for TSM-107-03-SM-DH-A-K-TR in a low-profile PCB enclosure?
The dual-row horizontal (DH) mating style of TSM-107-03-SM-DH-A-K-TR means the mating connector approaches from the side rather than from above, keeping the connected cable or wire harness running parallel to the PCB surface. With 14 positions at 0.100" (2.54 mm) pitch, this low-profile mating is particularly useful in shallow enclosures or panel-mount designs where a vertical cable exit would exceed the internal clearance height available.
How does the alignment key on TSM-107-03-SM-DH-A-K-TR prevent field wiring mistakes on a 14-position connector?
The alignment key (K suffix) on TSM-107-03-SM-DH-A-K-TR physically restricts insertion to the correct mating orientation, preventing an off-by-one or reversed mating that could mis-connect 14 signal lines. This is especially important in field-wired equipment where technicians may service the PCB without the original wiring diagram, ensuring the horizontal cable harness cannot be inserted backward and protecting downstream circuit components from incorrect signal routing.
For a 14-signal interface requiring SMT processing, what advantage does TSM-107-03-SM-DH-A-K-TR offer over a through-hole dual-row strip?
Choosing TSM-107-03-SM-DH-A-K-TR allows the 14-position, 0.100" pitch connector to be processed through the same reflow soldering step as other SMT components on the board, eliminating the need for a separate through-hole wave solder or hand-solder operation. This reduces total assembly time and cost per board, which becomes significant in volume production runs where adding a single through-hole soldering step adds measurable cycle time and labor cost per unit.
