What are the key features of TSM-120-04-S-DH-A-K-TR?
- 40 positions on a 0.100-inch pitch dual-row layout maximizes signal density in a space-efficient surface-mount footprint
- Through-hole heat stake retention pins lock the connector body to the PCB before soldering, preventing float during reflow
- Tape-and-reel (TR) packaging ensures compatibility with automated pick-and-place assembly for high-volume PCB production
- Surface-mount termination eliminates through-hole drilling, simplifying multilayer PCB design and reducing fabrication cost
What is TSM-120-04-S-DH-A-K-TR used for?
The TSM-120-04-S-DH-A-K-TR is suited for high-density signal interconnection on surface-mount PCBs in industrial controllers, embedded computing modules, and communication equipment. Its 40-position dual-row format accommodates wide data buses or mixed signal and power connections in a single connector. The tape-and-reel packaging makes it a practical choice for automated SMT assembly lines producing high-volume boards.

Frequently Asked Questions
How many positions does the TSM-120-04-S-DH-A-K-TR have, and what is its pin pitch?
The TSM-120-04-S-DH-A-K-TR provides 40 positions arranged in a dual-row configuration on a 0.100-inch (2.54 mm) pitch. This standard pitch spacing is compatible with a wide range of mating headers and IDC cable connectors, simplifying second-source and interoperability decisions for the system designer.
What packaging format does the TSM-120-04-S-DH-A-K-TR use, and how does that affect manufacturing?
The -TR suffix designates tape-and-reel packaging, which feeds the connector into pick-and-place machines automatically during SMT assembly. This reduces per-unit handling time compared to tube or tray formats, lowers placement error rates, and supports high-volume production runs typically exceeding 1000 units per reel.
How does the dual heat stake (DH) retention feature on the TSM-120-04-S-DH-A-K-TR prevent connector movement during reflow soldering?
The dual heat stake pins press into matching PCB holes and are thermally deformed after insertion, creating a mechanical lock that holds the connector body flat against the PCB surface. This prevents the connector from shifting or floating during the reflow oven cycle, where board temperatures typically reach 245 degrees C, ensuring all 40 pads maintain registration with the solder paste deposits.
For which signal interface applications is the TSM-120-04-S-DH-A-K-TR well suited compared to a right-angle version?
The vertical (straight) surface-mount style of the TSM-120-04-S-DH-A-K-TR is preferred when the mating connector plugs in perpendicular to the PCB, such as on edge-accessible interface panels in 1U rack equipment or backplane daughter-card systems. It allows a direct vertical mate with a 40-pin cable header without the additional height a right-angle connector would add to the PCB profile.
