What are the key features of TSM-124-01-L-DH-A-K-TR?
- 48-position single-row layout at 0.100 inch (2.54 mm) pitch providing a long, low-profile interface for parallel bus and I/O expansion connections on industrial and embedded PCBs
- Low-profile dual-height (L-DH) body reduces overall connector height while maintaining precise board-to-board standoff, enabling slim stacked assemblies with controlled inter-board clearance
- Keying (K) and tape-and-reel (TR) options deliver anti-mismating protection and automated SMT assembly compatibility for error-free, high-volume production of 48-position board interconnects
What is TSM-124-01-L-DH-A-K-TR used for?
The TSM-124-01-L-DH-A-K-TR is used in single-board computer (SBC) expansion interfaces, industrial I/O modules, and embedded system backplanes where 48 positions at 0.100 inch pitch provide sufficient capacity for address, data, control, and power routing. Its low-profile dual-height design is particularly suited to thin-profile enclosures such as DIN-rail controllers and panel-mount PLCs where vertical space is constrained. The keying option and tape-and-reel format streamline both assembly and field installation, preventing connector damage from incorrect mating.

Frequently Asked Questions
How many positions and rows does the TSM-124-01-L-DH-A-K-TR offer and what bus widths does it support?
The TSM-124-01-L-DH-A-K-TR provides 48 positions in a single-row configuration at 0.100 inch (2.54 mm) pitch. This count accommodates a 32-bit data bus plus 8 address lines and 8 control or power pins in a single connector row, making it well suited for CPU-to-I/O expansion board interfaces and memory bus connections in embedded industrial systems where wide parallel data paths are required.
When is the low-profile dual-height (L-DH) body of the TSM-124-01-L-DH-A-K-TR preferred over a standard-height terminal strip?
The L-DH profile is preferred when two PCBs must be stacked within a height-constrained enclosure, such as a DIN-rail controller with 35 mm total vertical clearance, and the connector must provide a controlled inter-board standoff without adding excess height. The low-profile body typically reduces above-board height by 1-2 mm compared to standard-height TSM variants, allowing designers to maintain tight board separation while still clearing tall SMD components such as 8 mm tall electrolytic capacitors mounted on the lower board.
What procurement advantage does the tape-and-reel (TR) format of the TSM-124-01-L-DH-A-K-TR provide for production runs?
The tape-and-reel (TR) format packages the TSM-124-01-L-DH-A-K-TR on industry-standard 8 mm or wider carrier tape wound on reels of 500 to 1,000 pieces, compatible with automated pick-and-place feeder systems used in SMT production lines. This eliminates manual connector placement across the 48-position footprint, reducing assembly cycle time by up to 80% compared to hand-placement and enabling consistent solder paste coverage across all 48 pads before reflow at 245°C peak temperature.
