What are the key features of TSM-124-01-FM-DH-A-K-TR?
- 48-position dual-row terminal strip at 0.100 inch (2.54 mm) pitch for standard density SMT board interconnects
- Flush-mount (FM) low-profile design minimizes connector height above PCB for space-constrained enclosure fits
- Tape-and-reel (TR) packaging supports automated pick-and-place SMT assembly for high-volume production
What is TSM-124-01-FM-DH-A-K-TR used for?
The TSM-124-01-FM-DH-A-K-TR is suited for embedded control boards, industrial automation modules, and consumer electronics that require a 48-position dual-row SMT terminal strip at the standard 0.100 inch pitch. The flush-mount low-profile format is particularly useful in slim enclosures where PCB-to-enclosure clearance is below 5 mm. Its dual-header (DH) configuration enables flexible signal and power assignment across 48 pins without requiring two separate connectors, simplifying PCB layout and Bill of Materials.

Frequently Asked Questions
How many positions and rows does TSM-124-01-FM-DH-A-K-TR provide, and what pitch connects the signals?
The TSM-124-01-FM-DH-A-K-TR provides 48 positions arranged in 2 rows of 24 pins at 0.100 inch (2.54 mm) pitch — the industry-standard spacing compatible with a broad range of mating socket strips and wire-to-board connectors. This configuration supports 48 independent signal or power assignments, making it suitable for GPIO expansion, sensor interfacing, or address/data bus routing in embedded systems.
For a slim industrial controller with limited PCB-to-panel clearance, why is the flush-mount (FM) profile of TSM-124-01-FM-DH-A-K-TR beneficial?
The flush-mount (FM) profile of TSM-124-01-FM-DH-A-K-TR keeps the connector body at a minimal height above the PCB surface, typically under 3 mm, compared to standard-height terminal strips that may exceed 5 mm. In industrial controllers mounted inside DIN-rail enclosures or thin wall-mount housings where PCB-to-panel clearance is 4 mm or less, the FM profile avoids mechanical interference while still providing all 48 positions at 0.100 inch pitch.
Can TSM-124-01-FM-DH-A-K-TR be used as a lower-cost alternative to fine-pitch connectors in applications where signal density is not critical?
Yes, for designs where 48 signals or fewer must cross a board boundary and the PCB area budget allows 0.100 inch pitch spacing, TSM-124-01-FM-DH-A-K-TR offers a cost advantage over 0.050 inch pitch high-density connectors, which require tighter PCB tolerances and more expensive controlled-impedance fabrication. Standard 0.100 inch pitch connectors are also available from multiple vendors, providing better supply chain flexibility and lower component cost for non-high-speed signal applications.
