Key Features
- 18 contact positions in a dual-row layout at 0.100 inch (2.54 mm) standard pitch for high signal density per connector unit
- Dual-height (DH) vertical configuration accommodates taller mating connectors and increases clearance for cable routing above the PCB surface
- Polarised (P) housing prevents incorrect connector insertion across all 18 positions, reducing assembly errors in production
- Tape-and-reel (TR) packaging enables automated pick-and-place SMT assembly at high production volumes without manual loading
Applications
The TSM-109-03-FM-DH-A-P-TR is designed for multi-signal board-to-board and module interconnect applications in embedded computing, industrial automation, and test-and-measurement platforms that require 18 contacts at the standard 0.100-inch pitch. The dual-height polarised SMT design suits applications where cable harness assemblies must clear adjacent components by more than a few millimetres, such as in power-distribution boards and backplane interfaces. The tape-and-reel packaging also makes it an efficient choice for high-throughput SMT production lines in consumer electronics and telecommunications hardware.

Frequently Asked Questions
What does the dual-height (DH) designation in the TSM-109-03-FM-DH-A-P-TR mean for physical connector clearance on a PCB?
The dual-height (DH) designation indicates that the TSM-109-03-FM-DH-A-P-TR has a taller insulator body than a standard-height terminal strip at the same 0.100-inch (2.54 mm) pitch, providing additional vertical clearance between the mating connector and the PCB surface. This extra height — typically several millimetres above the standard profile — allows cable bundles, ribbon cables, or adjacent tall components to route over the connector body without interference, which is critical in densely populated boards where component height budgets are tightly managed.
How many contact positions does the TSM-109-03-FM-DH-A-P-TR provide, and what is the dual-row arrangement?
The TSM-109-03-FM-DH-A-P-TR provides 18 contact positions arranged in 2 rows of 9 contacts each at a 0.100-inch (2.54 mm) pitch. This dual-row layout fits 18 signal lines into a connector body approximately 20.3 mm long, which is significantly more compact than a single-row 18-position strip that would require roughly 43.2 mm of board edge length at the same pitch. The dual-row configuration is well-matched to standard 18-conductor ribbon cable assemblies and IDC socket housings.
Why is polarisation important in the TSM-109-03-FM-DH-A-P-TR for automated assembly lines?
The polarised (P) housing on the TSM-109-03-FM-DH-A-P-TR includes a mechanical key that allows the mating connector to engage in only one orientation across all 18 contact positions. On automated cable assembly lines and in the field where technicians may handle dozens of identical connectors, the polarisation feature eliminates the risk of inserting the cable 180 degrees rotated, which at 18 pins could apply signals to the wrong rails and damage sensitive ICs. Polarisation is especially valuable when working with power and ground pins interleaved among signal lines in the dual-row 0.100-inch pattern.
What tape-and-reel format does the TSM-109-03-FM-DH-A-P-TR use, and how many units does a standard reel hold?
The TSM-109-03-FM-DH-A-P-TR is packaged in tape-and-reel (TR) format on a standard reel compliant with EIA-481 carrier tape specifications, typically holding 500 to 1,000 units per reel depending on the connector body size and the 0.100-inch (2.54 mm) pitch component pocket spacing. The tape-and-reel format feeds directly into standard pick-and-place machine feeders, enabling continuous automated SMT placement of the 18-position strip at line speeds matching other SMT components and eliminating the per-board manual placement labour cost at volumes above a few hundred units.
