What are the key features of TSM-104-04-SS-DH-A-K-TR?
- 8-position dual-row SMT layout on a 0.100" (2.54 mm) pitch with double-height (DH) shroud providing robust alignment and mechanical protection for the mating header
- Stainless steel (SS) hold-down hardware increases pull-off strength and board retention, critical in vibration-prone environments such as industrial controls and automotive accessories
- Tape-and-reel (TR suffix) format with alternate A-K polarization keying to prevent incorrect header insertion during PCB assembly and field maintenance
What is TSM-104-04-SS-DH-A-K-TR used for?
The TSM-104-04-SS-DH-A-K-TR is suited for small-form-factor embedded modules, sensor interface daughterboards, and portable industrial instruments where an 8-pin polarized dual-row SMT socket with enhanced mechanical retention is needed. Its double-height shroud and stainless steel hold-downs also make it a reliable choice for automotive accessory boards and robotics electronics exposed to mechanical shock and vibration.

Frequently Asked Questions
What does the DH suffix mean on the TSM-104-04-SS-DH-A-K-TR, and how does it benefit mechanical assembly?
The DH suffix designates a double-height shroud on the TSM-104-04-SS-DH-A-K-TR. This taller shroud extends approximately twice the standard height around the 8 contacts, providing deeper engagement with the mating header during insertion, improving alignment in automated assembly, and offering greater mechanical protection against side-load forces that could damage contacts in vibration-prone environments.
Why does the TSM-104-04-SS-DH-A-K-TR include stainless steel hold-down hardware, and when is that critical?
The SS (stainless steel) hold-down hardware in the TSM-104-04-SS-DH-A-K-TR anchors the connector body to the PCB with significantly higher pull-off resistance than standard plastic mounting feet—typically increasing retention force by several newtons. This is critical in portable devices, automotive electronics, and industrial equipment subject to mechanical shock (per IEC 68-2-27) or sustained vibration that could otherwise cause the connector to lift off its solder pads.
For an 8-pin sensor breakout module, how does the TSM-104-04-SS-DH-A-K-TR compare to a simpler open-top SMT socket?
Compared to an unshrouded open-top 8-pin SMT socket, the TSM-104-04-SS-DH-A-K-TR's polarization keying (A-K) prevents reversed mating, the double-height shroud guides insertion in low-visibility field scenarios, and the stainless steel hold-downs survive higher mechanical loads. For a sensor breakout module handling analog signals up to 1 A per contact at 100 V, these features reduce field-repair costs and connector failure rates.
What contact ratings apply to the TSM-104-04-SS-DH-A-K-TR for signal and low-power lines?
The TSM-104-04-SS-DH-A-K-TR follows SAMTEC TSM-series ratings of approximately 1 A per contact at up to 100 V working voltage. Its 8 dual-row positions can carry digital control signals, SPI or UART communication lines, and low-power 3.3 V or 5 V supply rails simultaneously, making it a versatile 8-pin interface for microcontroller peripheral boards and sensor modules.
