What are the key features of TSM-127-04-T-DH-P-TR?
- 54-position dual-row terminal strip with 0.100" (2.54 mm) pitch standard spacing
- Top-entry (T) contact orientation for vertical mating connections
- Through-hole board lock (P) pins provide additional PCB retention strength
- Tape-and-reel (TR) packaging for automated SMT pick-and-place compatibility
- Dual-row (DH) housing for maximum contact density in minimal board area
What is TSM-127-04-T-DH-P-TR used for?
The TSM-127-04-T-DH-P-TR serves as a high-density vertical-mating interconnect in industrial automation, data acquisition systems, and embedded computing platforms. The through-hole board lock pins add mechanical retention to hold the surface-mount connector secure under mating loads or vibration. Tape-and-reel packaging enables seamless integration into automated SMT manufacturing for high-volume production programs.

Frequently Asked Questions
How does the through-hole board lock on TSM-127-04-T-DH-P-TR improve connector retention on the PCB?
The through-hole board lock (P) pins press into PCB drilled holes, anchoring the surface-mount connector body and resisting the pull-off forces that occur during 54-pin mating and unmating cycles. This significantly improves mechanical retention compared to solder-only SMT attachment, which is especially useful in designs subject to vibration or repeated connector insertions.
What is the pin count and pitch of TSM-127-04-T-DH-P-TR, and is it compatible with standard mating connectors?
TSM-127-04-T-DH-P-TR provides 54 contact positions at a 0.100 inch (2.54 mm) pitch in a dual-row layout. This is a widely used standard pitch, and the connector mates with compatible Samtec TSW or SSW series receptacles or other 0.100 inch pitch 54-pin dual-row socket strips available in the market.
Why would a design engineer choose TSM-127-04-T-DH-P-TR over a version without board lock pins?
Engineers select the board lock version when the connector faces repeated mating cycles or mechanical stress in industrial or handheld equipment. For applications with 54 mated pins, the peel and shear forces on SMT pads can lift pads over time without mechanical anchoring. The through-hole board lock pins distribute these forces to the PCB substrate instead of the solder joints.
What procurement packaging option does TSM-127-04-T-DH-P-TR offer for automated assembly?
TSM-127-04-T-DH-P-TR is supplied in tape-and-reel format, making it compatible with standard automated pick-and-place machines used in high-volume SMT lines. Buyers can order reel quantities to minimize per-part handling costs, and Samtec authorized distributors typically stock tape-and-reel reels ready for delivery within standard lead times.
