Key Features
- 16-position dual-row SMT terminal strip with 2.54 mm (0.100") pitch for high-density board-level connectivity
- Tape-and-reel (TR) packaging supports high-volume automated pick-and-place assembly at production scale
- Keyed (K) and shrouded (DH) housing design prevents mis-mating and protects contacts in harsh environments
Applications
The TSM-108-04-SM-DH-A-K-TR suits high-density PCB designs in industrial control systems and data acquisition boards where a dual-row 2.54 mm pitch surface-mount header provides reliable board-to-board or board-to-wire interconnection. Its keyed shroud prevents incorrect mating during field installation or rework, making it valuable in panel-mount instrumentation and power distribution modules. The tape-and-reel format integrates seamlessly into automated SMT assembly lines for consumer electronics and communications hardware.

Frequently Asked Questions
How many positions does the TSM-108-04-SM-DH-A-K-TR provide and how are they arranged across its dual-row body?
The TSM-108-04-SM-DH-A-K-TR offers 16 positions arranged in 2 rows of 8 contacts each, on a 2.54 mm (0.100") row pitch and 2.54 mm column pitch. This dual-row, 8-position-per-row layout fits a footprint of approximately 17.78 mm × 5.08 mm on the PCB.
What assembly process does the tape-and-reel packaging of the TSM-108-04-SM-DH-A-K-TR support?
The TR (tape-and-reel) suffix means the connectors are packaged on reels compatible with standard SMT pick-and-place equipment, enabling automated surface-mount placement at rates above 1000 parts per hour on a typical assembly line. This packaging reduces manual handling errors compared with tray or bulk formats for production volumes of several thousand units or more.
In which industrial or test environments does the keyed shroud on the TSM-108-04-SM-DH-A-K-TR prevent costly mis-mating events?
The keyed (K) shroud on the TSM-108-04-SM-DH-A-K-TR physically blocks reversed or offset cable-side connector insertion across all 16 positions. This is essential in field-service scenarios—such as replacing control boards in motor drives, PLC backplanes, or test fixture harnesses—where a 180° mis-insertion could apply incorrect voltages (e.g. 24 V DC to a 3.3 V logic rail) and damage downstream ICs.
What current and voltage rating should a designer assume for the TSM-108-04-SM-DH-A-K-TR contacts?
SAMTEC TSM series surface-mount terminal strips with 2.54 mm pitch contacts are rated for approximately 3 A per contact at up to 250 V AC/DC under typical conditions. For a 16-position dual-row connector this allows carrying up to 48 A total if all pins are used for power distribution, though thermal derating applies above 25°C ambient and at high pin-count current loads.
