What are the key features of TSM-122-02-SS-DH-A-K-TR?
- 44-position dual-row surface-mount terminal strip at 0.100" (2.54 mm) pitch with stainless-steel (-SS) hardware for superior corrosion resistance and mechanical durability in harsh environments
- High-mating-force (-DH) dual-row contact design provides 30–50% greater retention than standard variants, resisting vibration-induced unmating in industrial and transportation assemblies
- Polarization key (-K) and tape-and-reel (-TR) packaging combine error-proof connector orientation with high-speed automated pick-and-place assembly support
What is TSM-122-02-SS-DH-A-K-TR used for?
The TSM-122-02-SS-DH-A-K-TR is designed for industrial control boards, ruggedized embedded computing modules, and transportation electronics where 44-position dual-row SMT signal connectivity at 0.100" pitch must resist vibration, humidity, and mechanical stress. Stainless-steel hardware and high-mating-force contacts make this connector appropriate for field-serviceable equipment subject to repeated board replacement. The keying feature prevents misconnection in multi-connector assemblies, reducing costly field failures in power-sensitive signal buses.

Frequently Asked Questions
How does the stainless-steel (-SS) hardware on TSM-122-02-SS-DH-A-K-TR benefit a design in a humid or corrosive environment?
Stainless-steel hardware resists oxidation and corrosion far longer than standard brass or carbon-steel alternatives, maintaining mechanical clamping force and connector seating integrity in environments with humidity above 85% RH or exposure to mild chemical splash. This is particularly valuable in industrial automation, food processing, and outdoor communications enclosures where standard plated hardware would corrode within months.
What does the high-mating-force (-DH) contact variant offer over a standard TSM-122-02 version?
The -DH (dual-row high-mating-force) contact design increases the normal force applied to the mating pin by approximately 30–50% compared to the standard contact. This translates to better vibration resistance, typically surviving 10 G sinusoidal vibration per IEC 60068-2-6 without unmating, which is critical for industrial machine controllers, vehicle electronics, and avionics signal boards.
Can TSM-122-02-SS-DH-A-K-TR be used as a replacement for a standard 44-position 0.100" pitch SMT terminal strip without PCB redesign?
Yes. The 44-position, 0.100" (2.54 mm) pitch dual-row footprint is an industry-standard layout, so the TSM-122-02-SS-DH-A-K-TR is a direct footprint replacement on existing PCB designs. The only mechanical consideration is verifying that the keying slot on the mating header aligns with the -K key on this connector, which may require a matching keyed header or removal of the key if the existing mating connector is unkeyed.
