What are the key features of TSM-123-04-TM-DH-A-K-TR?
- 46-position dual-row SMT terminal strip with 0.100 inch (2.54 mm) pitch providing 46 independent signal or power channels in a standard-pitch compact footprint
- Tall profile (-04 height code) offering additional pin length for secure wire insertion and improved pull-out force retention in wire-to-board applications
- Tape-and-reel (-TR) packaging and gold-plated contacts ensuring automated placement accuracy and low contact resistance across thousands of mating cycles
What is TSM-123-04-TM-DH-A-K-TR used for?
The TSM-123-04-TM-DH-A-K-TR is well suited for board-to-board and wire-to-board interconnect in industrial control panels, embedded computing backplanes, and programmable logic controller (PLC) expansion modules requiring 46 channels at 0.100 inch pitch. Its dual-row SMT format simplifies PCB layout compared to through-hole alternatives, while the taller pin height accommodates housing clips and wire retention features in cable harness assemblies. The tape-and-reel format supports high-volume automated assembly of server management boards and networking I/O modules.

Frequently Asked Questions
How does the 46-position dual-row layout of the TSM-123-04-TM-DH-A-K-TR compare to single-row alternatives for PLC expansion module designs?
A dual-row 46-position strip at 0.100 inch pitch occupies approximately 58.4 mm of board length compared to a single-row strip of equivalent pin count that would require the same length but double the board-edge footprint width. In PLC expansion modules constrained to a 70 mm wide card edge, the dual-row layout accommodates all 46 signals while leaving more than 10 mm of clearance for edge labeling and mechanical guide features.
What does the -04 height designation in the TSM-123-04-TM-DH-A-K-TR indicate and how does it affect wire-to-board insertion depth?
The -04 height designation specifies the fourth increment in SAMTEC's TSM height series, which corresponds to a taller insulator body allowing pin tails to extend approximately 4 mm above the PCB after reflow. This additional height provides sufficient engagement length for wire crimp contacts or housing clips, supporting a mating retention force of at least 1 N per contact in wire-to-board applications with 22 AWG to 28 AWG wire gauges.
Can the TSM-123-04-TM-DH-A-K-TR be used as an alternative to through-hole dual-row headers in mixed-technology PCB designs?
Yes, when a PCB undergoes only reflow soldering and lacks a wave soldering step, the SMT TSM-123-04-TM-DH-A-K-TR is a direct functional alternative to through-hole dual-row headers at 0.100 inch pitch. The SMT version eliminates the need for drilling 46 via pairs, which at 0.8 mm drill diameter would consume approximately 230 mm2 of PCB area, and allows component placement on both sides of the board beneath the connector footprint.
