Key Features
- 21-position single-row SMT terminal strip at 0.100-inch (2.54mm) pitch for standard-pitch board-to-wire or board-to-board connections
- Shrouded (SH) housing provides mechanical keying and polarization to prevent misalignment during connector mating
- Tape-and-reel (TR) packaging supports automated pick-and-place SMT assembly in high-volume production lines
- Vertical (V) orientation minimizes connector height above the PCB surface for low-profile electronic assemblies
Applications
The TSM-121-05-L-SH-P-TR is well suited for 21-pin board-to-wire and board-to-board interconnect applications in industrial control panels, consumer electronics, and embedded computing platforms that require a standard 0.100-inch-pitch SMT connector. Its shrouded housing prevents incorrect mating orientation, improving reliability in field-deployed and production assemblies. The tape-and-reel format enables seamless integration into high-speed automated SMT lines for both prototype and volume production of control and communication boards.

Frequently Asked Questions
How many positions does the TSM-121-05-L-SH-P-TR have, and what pitch spacing does it use?
The TSM-121-05-L-SH-P-TR is a 21-position single-row terminal strip with a standard 0.100-inch (2.54mm) pitch. This pitch is compatible with a wide range of mating headers and cable connectors, making it practical for industrial control, embedded computing, and consumer electronics boards requiring 21-pin interfaces.
What does the shrouded housing (SH) on the TSM-121-05-L-SH-P-TR add to an interconnect design?
The shrouded (SH) housing surrounds the 21 contact pins with a polarizing shell that prevents misaligned or reversed mating connections. This mechanical keying feature is especially valuable in field-service and production environments where connectors may be re-mated frequently, reducing the risk of bent pins or reversed signal connections at 0.100-inch pitch.
Is the TSM-121-05-L-SH-P-TR suitable for automated SMT assembly, and in what packaging does it ship?
Yes, the TR suffix indicates tape-and-reel packaging, making the TSM-121-05-L-SH-P-TR compatible with standard pick-and-place equipment for automated SMT reflow assembly. This is ideal for high-volume production of boards needing a 21-position 0.100-inch-pitch surface-mount connector without manual placement.
How does the TSM-121-05-L-SH-P-TR compare to a through-hole 21-pin header for PCB space efficiency?
As a surface-mount connector with vertical orientation, the TSM-121-05-L-SH-P-TR does not require through-hole drilling, keeping the bottom-side routing layer clear for additional signals. At 0.100-inch (2.54mm) pitch with 21 positions and a shrouded housing, it also occupies less board area than equivalent through-hole strips, benefiting compact PCB designs in embedded systems and instrumentation.
