What are the key features of TSM-122-02-SM-DH-A-K-TR?
- 44-position dual-row SMT terminal strip at 2.54 mm (0.100") pitch for high-capacity signal routing in a single compact connector
- Short mount (SM) profile reduces overall connector height, enabling tighter PCB-to-board stack clearances in space-limited assemblies
- Tape and reel (TR) packaging allows high-speed automated pick-and-place SMT assembly in volume PCB production
- Dual-row layout with 22 positions per row provides stable mechanical mounting and balanced solder joint distribution across the 44-pin footprint
What is TSM-122-02-SM-DH-A-K-TR used for?
The TSM-122-02-SM-DH-A-K-TR is ideal for low-profile board-to-board interconnect in portable electronics, embedded computing modules, and compact industrial control systems requiring 44-position dual-row signal routing at 2.54 mm pitch. Its short mount profile suits applications with constrained inter-board clearance such as tablet mainboards, wearable device PCBs, and slim form-factor communication modules where vertical space is at a premium.

Frequently Asked Questions
What does the short mount (SM) designation mean for TSM-122-02-SM-DH-A-K-TR in height-constrained designs?
Short mount (SM) refers to a reduced connector body height compared to standard variants, typically lowering the profile by 1 mm to 2 mm. For the 44-position dual-row TSM-122-02-SM-DH-A-K-TR, this allows PCB-to-board stacking with inter-board clearance as tight as 3 mm, critical for slim consumer and embedded devices.
How many signal positions does TSM-122-02-SM-DH-A-K-TR route, and how does this compare to smaller TSM variants?
TSM-122-02-SM-DH-A-K-TR provides 44 positions across 2 rows of 22 pins each at 2.54 mm (0.100 inch) pitch. This offers nearly double the signal capacity of a 24-position TSM variant in the same connector series, making it suitable for higher-channel-count parallel interfaces and bus expansions on embedded boards.
Which compact electronic or industrial designs benefit most from TSM-122-02-SM-DH-A-K-TR?
Slim tablet mainboards, wearable device PCBs, portable medical monitors, and compact industrial HMI panels requiring 44-position dual-row signal routing in a low-profile SMT connector benefit most from TSM-122-02-SM-DH-A-K-TR, particularly when inter-board height budgets are restricted to less than 5 mm.
Is TSM-122-02-SM-DH-A-K-TR a viable alternative to a 50-position connector when the design uses only 44 active signals?
Yes. TSM-122-02-SM-DH-A-K-TR eliminates 6 unused positions compared to a 50-position connector, reducing the SMT footprint length by approximately 7.6 mm and lowering per-unit connector cost. This is advantageous in 44-signal interfaces where minimizing board area and BOM cost takes priority over future signal expansion.
