What are the key features of STMM-122-02-L-D-SM-K-TR?
- 44-position dual-row 2.00 mm pitch shrouded layout in a 1.959 inch body length enabling high-density board-to-cable signal routing with keyed polarization
- Low-profile surface-mount configuration with body depth of 0.24 inch supporting compact PCB stack height in densely populated board designs
- Tin (Sn) over Nickel (Ni) barrier termination contacts with SAMTEC's SQ PIN-SKT contact style ensuring robust rectangular contact engagement and consistent electrical continuity
What is STMM-122-02-L-D-SM-K-TR used for?
The STMM-122-02-L-D-SM-K-TR is suited for industrial control modules, embedded computing carrier boards, and medical devices where a 2.00 mm pitch 44-position dual-row shrouded connector provides keyed, mis-mate-protected board-to-cable connectivity. Its low-profile body depth of 0.24 inch and SMT termination support integration in space-constrained PCB assemblies that undergo standard reflow soldering. Tape and Reel packaging enables high-volume automated SMT production of communication equipment, robotics controllers, and test instruments requiring dual-row shrouded connectors.

Frequently Asked Questions
What are the key dimensions and position count of the STMM-122-02-L-D-SM-K-TR?
The STMM-122-02-L-D-SM-K-TR measures 1.959 inch in body length, 0.237 inch in breadth, and 0.24 inch in depth, with 44 positions arranged in a dual-row layout at 2.00 mm pitch, making it a compact surface-mount shrouded connector for high-density board-to-cable interconnects in industrial and embedded PCB designs.
How does the keyed shroud of the STMM-122-02-L-D-SM-K-TR prevent mis-mating during field assembly?
The keyed shrouded housing of the STMM-122-02-L-D-SM-K-TR incorporates a polarizing key that physically prevents reversed or offset cable insertion across all 44 positions, reducing wiring errors in field-assembled industrial automation panels, robotics systems, and medical instruments where technicians may connect and disconnect cable harnesses frequently.
What is the difference between the STMM-122-02-L-D-SM-K-TR and the STMM-122-02-S-D-SM-K-TR?
Both the STMM-122-02-L-D-SM-K-TR and STMM-122-02-S-D-SM-K-TR share the same 44-position dual-row 2.00 mm pitch shrouded layout and tin-over-nickel contact finish, but differ in the contact tail length designation (L versus S), which affects solder pad engagement depth and is selected based on PCB copper weight, solder paste volume, and reflow profile requirements.
Is the STMM-122-02-L-D-SM-K-TR available in packaging suitable for automated SMT assembly?
Yes, the TR suffix indicates Tape and Reel packaging and the SM designation confirms surface-mount termination, making the STMM-122-02-L-D-SM-K-TR fully compatible with automated SMT pick-and-place and reflow soldering for high-volume production of boards needing a 44-position 2.00 mm pitch dual-row shrouded connector with a 1.959 inch footprint.
