Frequently Asked Questions
What position count and row configuration does the TSM-118-02-LM-DH-A-K-TR provide?
The TSM-118-02-LM-DH-A-K-TR features 36 positions in a dual-row configuration at 2.54 mm (0.100 inch) pitch. This layout efficiently routes 36 signals between PCBs while maintaining compatibility with the broad ecosystem of standard 2.54 mm pitch mating connectors commonly used in industrial and embedded board designs.
How does the long-mating contact design of the TSM-118-02-LM-DH-A-K-TR improve performance in vibration environments?
Long-mating contacts provide greater engagement depth compared to standard contacts, increasing the contact area and mechanical resistance to vibration-induced fretting or disconnection. This makes the TSM-118-02-LM-DH-A-K-TR suitable for industrial motor control panels and field instrumentation exposed to continuous vibration levels up to 10 G, where a shallow-mating connector would risk intermittent signal loss.
For a 36-channel signal board design, when would the TSM-118-02-LM-DH-A-K-TR be preferred over a 0.050-inch pitch alternative?
The 2.54 mm pitch of the TSM-118-02-LM-DH-A-K-TR is preferred when PCB trace routing requires more space between pins, when mating connectors must be hand-assembled or frequently disconnected, or when operating voltage ratings up to 250 V are required. Fine-pitch 1.27 mm alternatives offer higher density but reduce creepage distance and are harder to inspect during manual assembly.
In which procurement scenarios should engineers evaluate the TSM-118-02-LM-DH-A-K-TR tape-and-reel format?
The -TR suffix indicates tape-and-reel packaging, making the TSM-118-02-LM-DH-A-K-TR the correct choice for automated SMT pick-and-place production lines running volumes above 500 units per batch. Tape-and-reel eliminates manual kitting, reduces placement errors at 2.54 mm pitch, and is required by most contract manufacturers using standard AOI and reflow soldering equipment.
