What are the key features of TSM-124-04-TL-DH-A-K-TR?
- 48-position dual-row SMT terminal strip at 0.100" (2.54 mm) pitch providing high signal count for backplane and module interfaces
- Dual-height (DH) through-hole locating posts ensuring precise PCB alignment and preventing movement during reflow at up to 260°C
- TL (tall) body with 04 stacking height option enabling specific board separation distance in multi-board assemblies
- Tape-and-reel (TR) packaging supporting automated pick-and-place SMT assembly for high-volume production
What is TSM-124-04-TL-DH-A-K-TR used for?
The TSM-124-04-TL-DH-A-K-TR addresses 48-position dual-row board-to-board and module-to-backplane connectivity in industrial PLC racks, embedded computing carriers, and power-control interface boards requiring standard 0.100" pitch with defined stacking height. The tall body and dual-height locating posts improve mechanical stability and placement accuracy on large SMT panels processed in high-volume lines. Tape-and-reel delivery integrates directly with automated SMT assembly systems.

Frequently Asked Questions
What stacking height does the 04 designation provide on the TSM-124-04-TL-DH-A-K-TR for multi-board assemblies?
In SAMTEC's TSM series, the numeric mating height code 04 indicates a mating height of approximately 4 mm above the PCB surface at 0.100" (2.54 mm) pitch. This defined 4 mm board separation is appropriate for single-board-computer carrier designs, industrial I/O module stacks, and compact embedded assemblies where controlled inter-board clearance is needed for component height management and airflow.
How does the 48-position dual-row layout of TSM-124-04-TL-DH-A-K-TR compare to a single-row 48-pin alternative in terms of PCB length?
A dual-row 48-position connector at 0.100" (2.54 mm) pitch occupies approximately 31 mm of board length (24 positions per row x 1.27 mm between rows x 2 rows), while a single-row 48-pin strip would require 120 mm (48 x 2.54 mm). The dual-row TSM-124-04-TL-DH-A-K-TR therefore saves roughly 89 mm of board-edge length, critical for compact embedded modules and PLC backplanes with limited edge space.
In which industrial systems is the TSM-124-04-TL-DH-A-K-TR most commonly specified as a board-to-backplane connector?
The TSM-124-04-TL-DH-A-K-TR is commonly specified in industrial PLC backplane modules, motor-drive interface cards, and embedded computing carrier boards requiring 48-position dual-row connectivity at 0.100" (2.54 mm) pitch. Its rated operating temperature from -55°C to +125°C and the stability provided by dual-height locating posts make it suitable for harsh industrial environments including factory floors, CNC machine controllers, and power electronics enclosures.
What is the advantage of ordering TSM-124-04-TL-DH-A-K-TR in tape-and-reel format compared to tube or bulk packaging for a production run of 5,000 boards?
Tape-and-reel format for the TSM-124-04-TL-DH-A-K-TR enables direct feeder loading on pick-and-place machines, eliminating manual singulation and reducing placement cycle time by up to 30% versus tube-loaded components. For a 5,000-board production run, each reel typically holds 500 to 1,000 connectors, reducing operator changeover events and minimizing the risk of connector damage or contamination that can increase solder defect rates on 48-position 0.100" pitch pads.
