TSM-120-02-H-DH-P-TR SAMTEC Connector (Other) In Stock
SAMTEC TSM-120-02-H-DH-P-TR is a 40-position, dual-row, 0.100 inch pitch surface mount terminal strip with high-profile (H) contact posts for clearance over board components. The dual-row (DH) layout places 20 contacts per row in a compact SMT footprint ideal for embedded systems and I/O interface boards. Tape-and-reel packaging enables high-volume automated SMT placement in industrial and consumer applications.

What are the key features of TSM-120-02-H-DH-P-TR?
- 40-position dual-row SMT terminal strip at standard 0.100 inch (2.54 mm) pitch
- High-profile (H) contact posts provide additional clearance above board-mounted components
- Dual-row (DH) configuration with 20 contacts per row for flexible signal and power assignment
- Tape-and-reel (TR) packaging supports automated high-volume SMT pick-and-place production
- Compatible with a wide range of 0.100 inch pitch mating connectors and IDC cable assemblies
What is TSM-120-02-H-DH-P-TR used for?
The TSM-120-02-H-DH-P-TR is suited for embedded microcontroller expansion headers, PLC digital I/O modules, and test jig interfaces where a 40-pin dual-row SMT connector with extra post height is needed to clear adjacent components. Its standard 0.100 inch pitch provides broad compatibility with off-the-shelf mating housings, flat cables, and IDC crimp assemblies used across industrial, medical, and communication equipment.

Frequently Asked Questions
What is the significance of the high-profile (H) designation in the TSM-120-02-H-DH-P-TR?
The high-profile (H) designation means the contact posts of the TSM-120-02-H-DH-P-TR extend taller above the PCB surface than standard-profile variants, providing additional clearance for mating connectors over nearby board components. This is useful when tall capacitors, inductors, or ICs are populated within 5 mm of the header and a standard-height connector would prevent full cable seating.
How are the 40 positions arranged in the TSM-120-02-H-DH-P-TR and what pin assignments are typical?
The TSM-120-02-H-DH-P-TR is a dual-row (DH) connector with 20 positions per row at 0.100 inch (2.54 mm) pitch, providing 40 total pins. Engineers typically assign the two rows to separate functional groups such as digital I/O and power/ground, or to parallel bus signals and control lines, making efficient use of all 40 pins in microcontroller expansion and FPGA prototype headers.
Does the TSM-120-02-H-DH-P-TR accept standard IDC flat ribbon cable assemblies for prototype builds?
Yes, the TSM-120-02-H-DH-P-TR uses the industry-standard 0.100 inch pitch, which is compatible with 40-conductor flat ribbon cables and standard IDC connectors widely available from distributors. This allows rapid prototype cabling without custom harnesses and makes the connector interchangeable with equivalent 40-pin 0.100 inch headers from Molex, TE Connectivity, and other manufacturers.
What tape-and-reel quantity options exist for TSM-120-02-H-DH-P-TR in production sourcing?
Tape-and-reel (TR) packaging for the TSM-120-02-H-DH-P-TR is typically available in reels of 500 to 1000 pieces, depending on the distributor and SAMTEC factory run. For production programs assembling more than 500 boards per week, ordering full reels reduces feeder change frequency on pick-and-place machines and lowers per-unit connector handling costs compared to cut-tape quantities.
