What are the key features of TSM-109-03-TM-DH-P-TR?
- 18 positions in dual-row 0.100" (2.54 mm) pitch layout supporting industry-standard mating with IDC cables and 2.54 mm dual-row receptacles
- Polarized (P) housing keying prevents reverse mating of the 18-position connector to eliminate wiring errors in production and field service
- Gold-plated contacts rated 350V AC and 3A per pin with 30 µin finish ensuring long-term reliable connectivity from -55°C to +125°C
- Tape-and-reel (TR) format enables fully automated SMT pick-and-place assembly for high-volume production runs
What is TSM-109-03-TM-DH-P-TR used for?
TSM-109-03-TM-DH-P-TR is designed for industrial automation, embedded control modules, and communication hardware requiring an 18-pin, 2.54 mm pitch polarized surface mount connector with mechanical anchorage. The polarized DH (dual through-hole) tail design ensures correct installation and provides robust pull-out retention in panel-mounted industrial controllers and PLC expansion boards. It is also used in test and measurement docking stations and industrial I/O breakout boards where field-replaceable sub-assemblies demand consistent and error-free connector orientation.

Frequently Asked Questions
How many positions and what pitch does the TSM-109-03-TM-DH-P-TR provide, and what connectors does it mate with?
The TSM-109-03-TM-DH-P-TR has 18 positions arranged in a dual-row configuration at 0.100" (2.54 mm) pitch. It mates with standard 2.54 mm dual-row receptacles such as SAMTEC's TLW and TSW series, as well as industry-standard IDC ribbon cable connectors, making it compatible with a wide range of existing cable assemblies and daughter board sockets used in embedded systems and industrial controllers.
What do the DH tails contribute to the mechanical robustness of the TSM-109-03-TM-DH-P-TR?
The DH (dual through-hole) tail configuration adds 4 solder anchor points to the 18-position connector body, achieving pull-out retention typically exceeding 10 lb when fully soldered. Compared to surface-only pads, the through-hole tails penetrate the PCB and form fillets on both sides, providing critical mechanical strength in industrial panels subject to vibration between 10 Hz and 2000 Hz and thermal cycling from -55°C to 125°C.
Why would a hardware designer specify the polarized (P) variant TSM-109-03-TM-DH-P-TR instead of the non-polarized version?
The P (polarized) version incorporates a molded keying feature in the 18-position, 2.54 mm pitch housing that physically blocks reverse mating. In industrial and medical equipment boards where incorrect orientation could cause short circuits across the 3A rated contacts or reverse-bias sensitive ICs on the mating cable assembly, the polarized design adds a zero-cost safeguard against assembly errors, reducing field failure risk significantly.
What soldering process is recommended for the TSM-109-03-TM-DH-P-TR given its SM-DH hybrid construction?
The TSM-109-03-TM-DH-P-TR is compatible with standard SMT reflow soldering at peak temperatures up to 260°C per JEDEC J-STD-020 standards. The dual through-hole tails can be simultaneously reflowed with the surface mount pads in a single pass, or selectively wave-soldered after SMT reflow if the board design calls for two-step assembly. The 0.100" pitch through-hole tail spacing facilitates inspection and rework with standard soldering equipment.
Can TSM-109-03-TM-DH-P-TR be used in a stackthrough connector configuration with another PCB?
The TSM-109-03-TM-DH-P-TR functions as a terminal strip designed for vertical mating with a receptacle on a daughter board, making it suitable for stacked PCB architectures where 18 signals must be passed between two boards at 2.54 mm pitch. Board-to-board stacking heights from 8 mm to 20 mm can be achieved by selecting complementary mating receptacle stack heights, supporting modular designs in industrial controllers, development kits, and expansion backplanes.
