What are the key features of TSM-120-04-SM-DH-P-TR?
- 40-position dual-row SMT terminal strip on 0.100 inch (2.54mm) pitch
- Short-mount (-SM) profile for low standoff height in space-constrained PCB designs
- Gold-plated contacts providing low contact resistance and long mating cycle life
- Tape-and-reel (-TR) packaging enabling automated pick-and-place SMT production
- Dual-row (DH) layout with 20 pins per row for high-density signal routing
- Compatible with SAMTEC TSW and TSM mating connector families
What is TSM-120-04-SM-DH-P-TR used for?
The TSM-120-04-SM-DH-P-TR is used in embedded computing modules, networking switch cards, and industrial I/O expansion boards where a 40-position dual-row 0.100 inch pitch short-mount SMT connector is needed for dense signal interconnect in height-constrained assemblies. Its tape-and-reel packaging streamlines automated SMT production, and the gold-plated contacts provide reliable performance across the connector's service life in temperature-cycled and vibration-exposed industrial environments.

Frequently Asked Questions
What does the -SM suffix on TSM-120-04-SM-DH-P-TR mean, and how does it affect PCB assembly height?
The -SM suffix designates a short-mount profile, which reduces the standoff height of the 40-position dual-row 0.100 inch pitch connector compared to standard-mount variants. This shorter height is important for embedded modules, compact switch cards, or stacked PCB assemblies where available vertical clearance above the board is limited to just a few millimeters.
How are the 40 positions distributed across the dual-row footprint of TSM-120-04-SM-DH-P-TR?
The 40 positions are arranged in a dual-row layout at 0.100 inch (2.54mm) pitch, placing 20 pins per row. Designers can assign signals, power, and ground across both rows in a footprint roughly half the PCB length of a single-row 40-pin connector, simplifying routing on compact industrial I/O and networking boards.
Does TSM-120-04-SM-DH-P-TR support automated pick-and-place assembly, and what packaging format is available?
Yes. The -TR designation confirms tape-and-reel packaging, which is fully compatible with automated SMT pick-and-place machines. The 40-position short-mount dual-row connector at 0.100 inch pitch can be placed accurately and reflowed using standard SMT processes, enabling high-volume assembly without manual insertion for networking and industrial controller production lines.
What contact finish does TSM-120-04-SM-DH-P-TR use, and what mating connector families are compatible?
The TSM-120-04-SM-DH-P-TR uses gold-plated contacts, which maintain low resistance and resist corrosion over hundreds to thousands of mating cycles. It mates with SAMTEC TSW-series socket strips and compatible dual-row 0.100 inch pitch headers, enabling reliable 40-position board-to-board interconnects in industrial, telecom, and embedded computing systems.
