What are the key features of STMM-125-02-FM-D-SM-K-TR?
- 50-position dual-row shrouded configuration at 2.00 mm pitch with polarization key preventing mismated cable-mate connections
- Flush-mount (FM) profile minimizing connector height above the PCB surface for low-profile enclosure designs
- Surface-mount (SM) termination with tape-and-reel (TR) packaging supporting automated high-volume SMT assembly
- Dual-row layout delivering up to 50 signal or mixed power/signal connections in a compact shrouded footprint
What is STMM-125-02-FM-D-SM-K-TR used for?
The STMM-125-02-FM-D-SM-K-TR is well-suited for multi-wire internal cable harness connections in industrial automation controllers, robotic joints, and medical diagnostic equipment where 50 signals must route from a main PCB to peripheral modules via a shrouded, polarized interface. Its flush-mount profile keeps the connector's top surface close to the PCB, benefiting thin-profile enclosures and panel-mount designs with tight vertical clearance. The tape-and-reel SMT format enables high-throughput automated assembly in consumer electronics and telecommunications hardware requiring consistent placement accuracy.

Frequently Asked Questions
What position count and pitch does the STMM-125-02-FM-D-SM-K-TR provide for cable harness designs?
The STMM-125-02-FM-D-SM-K-TR offers 50 total positions in a dual-row layout at 2.00 mm pitch (25 per row). This provides a high pin-count shrouded interface in a compact footprint, supporting up to 50 individual signal or low-power connections at approximately 3 A per contact rating for light power distribution and signal routing.
How does the flush-mount (FM) profile of STMM-125-02-FM-D-SM-K-TR differ from standard and high-profile variants?
The flush-mount (FM) profile reduces the connector's above-board height by lowering the mating interface closer to the PCB surface compared to standard or high-profile (H) variants. This typically saves 1 mm to 3 mm of vertical clearance, making the FM variant preferable in thin-profile enclosures, sliding-tray server designs, and stacked board assemblies where height budget is less than 8 mm above the board.
Is the STMM-125-02-FM-D-SM-K-TR compatible with standard 2.00 mm pitch cable-mate plug assemblies?
Yes, the 2.00 mm pitch shrouded housing of the STMM-125-02-FM-D-SM-K-TR is designed to mate with SAMTEC IPMD and IDSD series 2.00 mm cable-mate plugs as well as compatible third-party 2.00 mm pitch dual-row housings. The polarization key ensures correct orientation, and the 50-position count matches standard harness assemblies used in industrial and embedded computing systems.
