What are the key features of STMM-123-02-FM-D-SM-K-TR?
- Dual-row 2.00 mm pitch female shrouded SMT terminal strip with 46 positions (23 per row) providing high-density polarized cable-mate board interconnect
- FM female contact style mates with corresponding STMM male headers, enabling secure board-to-cable assemblies with positive locking retention
- Tape-and-reel (TR) packaging with keyed (K) shroud for automated pick-and-place reflow assembly and error-free field installation in high-volume production
What is STMM-123-02-FM-D-SM-K-TR used for?
The STMM-123-02-FM-D-SM-K-TR serves as the female receptacle in 2.00 mm pitch dual-row cable-mate connector pairs used in industrial automation, telecommunications chassis, and server backplane assemblies where 46 signal or mixed power/signal contacts must mate with a keyed shroud to prevent wiring errors. Its surface mount SMT tails allow integration with standard PCB reflow processes, reducing assembly cost in high-volume runs. The female contact configuration simplifies harness-to-board connections in field-serviceable equipment requiring repeated mating cycles.

Frequently Asked Questions
How does STMM-123-02-FM-D-SM-K-TR differ from STMM-123-02-H-D-SM-K-TR in contact gender and application?
The FM suffix designates female contacts in the STMM-123-02-FM-D-SM-K-TR, while the H suffix in STMM-123-02-H-D-SM-K-TR indicates male contacts. The female version accepts male pins from a mating cable header, creating a latching 46-position 2.00 mm pitch pair suited for field-disconnectable harness assemblies in industrial and telecom systems.
What mating cycles and retention force should be expected for the keyed shroud female contacts of STMM-123-02-FM-D-SM-K-TR?
SAMTEC 2.00 mm pitch STMM series connectors are typically rated for a minimum of 30 mating cycles with positive retention force from the keyed shroud latch mechanism, ensuring the 46-position cable-mate assembly remains secure during vibration in industrial enclosures and server rack environments operating at up to 70°C ambient temperature.
Which PCB assembly process is compatible with the SMT tails of STMM-123-02-FM-D-SM-K-TR?
The surface mount (SM) tails of the STMM-123-02-FM-D-SM-K-TR are compatible with standard solder paste reflow processes, allowing the 46-position 2.00 mm dual-row female connector to be placed by pick-and-place machines from tape-and-reel at temperatures up to 260°C during IPC J-STD-020 reflow profiles.
