What are the key features of TSM-111-02-SM-DH-A-P-TR?
- 22-position dual-row 0.100 inch pitch layout providing 44 contact points for high-density signal routing on a single SMT connector footprint
- Polarization (P suffix) and dual-header (DH) features preventing mis-mating and ensuring correct board-to-board orientation during assembly
- Tape-and-reel (TR) packaging enabling automated pick-and-place SMT assembly for high-volume production efficiency
What is TSM-111-02-SM-DH-A-P-TR used for?
The TSM-111-02-SM-DH-A-P-TR is designed for high-density board-to-board signal interconnection in embedded computing modules, industrial automation controllers, and test equipment backplane systems. The 22-position dual-row configuration accommodates mixed signal, power, and ground routing in a compact 2.54 mm pitch footprint, reducing PCB area compared to multiple single-row connectors. Its polarized dual-header design eliminates incorrect mating risk in field-installed assemblies and automated manufacturing lines.

Frequently Asked Questions
How many contact positions does the TSM-111-02-SM-DH-A-P-TR provide and what is its contact pitch?
The TSM-111-02-SM-DH-A-P-TR provides 22 positions in a dual-row configuration on a 0.100 inch (2.54 mm) pitch, yielding 44 individual contact points per connector. This pin count supports comprehensive signal, power, and ground assignments in embedded module interfaces, SBC expansion headers, and industrial fieldbus connections without requiring multiple adjacent connectors sharing a PCB footprint.
What does the polarization feature on the TSM-111-02-SM-DH-A-P-TR prevent during PCB assembly and field installation?
The P (polarization) suffix on the TSM-111-02-SM-DH-A-P-TR adds a mechanical keying feature that prevents 180-degree reverse insertion into the mating header, protecting circuits from reversed power and signal connections. This is especially valuable when 44-pin dual-row assemblies are installed in dimly lit rack enclosures or by field technicians who may not reference polarity markings on PCBs with 2.54 mm pitch connectors.
How does selecting the TSM-111-02-SM-DH-A-P-TR over a through-hole terminal strip reduce PCB manufacturing cost?
The surface-mount construction of the TSM-111-02-SM-DH-A-P-TR eliminates the 44 drilled through-holes required by equivalent through-hole terminal strips, reducing PCB fabrication cost by approximately 5-15% per board in high-volume runs above 5,000 units. Combined with tape-and-reel (TR) packaging that supports automated placement at rates above 3,000 components per hour, the SMT approach significantly lowers total assembly cost versus manual through-hole insertion.
