What are the key features of TSM-131-04-LM-DH-P-TR?
- 62-position dual-row SMT terminal strip at 0.100" (2.54 mm) pitch supporting standard-density high pin-count PCB interconnects
- LM low-mount profile minimizing board separation distance to enable compact mezzanine stack heights down to 8 mm
- P (press-fit) retention ensuring secure mechanical hold-down to the PCB prior to reflow soldering
- Tape-and-reel (TR) format and DH dual-height options supporting automated SMT assembly for high-volume production
What is TSM-131-04-LM-DH-P-TR used for?
The TSM-131-04-LM-DH-P-TR is deployed in compact mezzanine and daughter card interfaces for industrial embedded computing, networking equipment, and FPGA evaluation boards. Its low-mount 62-position dual-row configuration at 0.100" pitch achieves minimal board-to-board clearance while maintaining reliable electrical connections across 62 signal channels. The press-fit retention feature provides mechanical stability during reflow soldering, making it particularly suitable for vertical PCB assemblies and vibration-prone environments.

Frequently Asked Questions
What does the LM (low-mount) designation mean for the board separation in TSM-131-04-LM-DH-P-TR assemblies?
LM indicates a low-mount connector body height, which reduces the standoff between mated PCBs. In the TSM-131 series, low-mount variants allow board-to-board separation starting at approximately 8 mm, compared to 12 mm or more for standard-height options, making them suitable for 1U rack and compact embedded modules with limited vertical clearance across all 62 positions.
How does the P (press-fit) retention feature benefit PCB assembly for this 62-pin connector?
The P suffix indicates mechanical press-fit or snap-in retention posts that hold the connector firmly to the PCB surface before and during reflow soldering. On a 62-pin SMT connector at 0.100" pitch, without retention the connector can shift during solder paste reflow, causing pad misalignment across multiple contacts. Press-fit posts ensure positional accuracy within 0.1 mm tolerance during the reflow profile up to 260°C.
How does TSM-131-04-LM-DH-P-TR differ from TSM-131-04-TL-DH-A-K-TR in terms of design application fit?
The LM-P variant uses a low-mount profile with press-fit retention and no keying, whereas the TL-K variant uses top-load mating with keying for polarization protection. Engineers targeting the lowest possible board separation under 10 mm where polarity control is maintained through PCB layout should choose the LM-P version; designers who need assembly-proof keying to prevent reversed insertion across all 62 channels at standard stack heights should prefer the TL-K variant.
