What are the key features of STMM-121-02-F-D-SM?
- 42-position dual-row shrouded terminal strip at 2.00 mm pitch delivering high-density cable-to-board signal connections in a compact surface-mount footprint
- Female (F) contact style mates with standard 2.00 mm male pin headers, simplifying cable assembly integration without adapters or custom tooling
- Shrouded housing provides mechanical protection for the 42 contacts during cable mating and prevents pin damage from accidental lateral contact force
- Surface-mount (SM) termination enables automated SMT reflow assembly for consistent and repeatable solder joint quality in high-volume PCB production
What is STMM-121-02-F-D-SM used for?
The STMM-121-02-F-D-SM is used in industrial control boards, embedded computing platforms, and test and measurement equipment where 42 signals must connect reliably between a PCB and a cable assembly at 2.00 mm pitch. The shrouded housing and female contact style simplify field-side cable harness assembly by guiding the mating male pin header into alignment during installation. Surface-mount termination supports automated high-volume PCB manufacturing in telecommunications, data acquisition, and robotics applications.

Frequently Asked Questions
How many positions does the STMM-121-02-F-D-SM provide and what contact gender does it use?
The STMM-121-02-F-D-SM has 42 positions in a dual-row (2 rows x 21 positions) layout at 2.00 mm pitch with female (F) contact style, designed to mate with standard 2.00 mm pitch male pin-header cable assemblies without requiring specialized mating connectors.
How does the shrouded housing on STMM-121-02-F-D-SM protect contacts during assembly and field use?
The shroud surrounding the 42 female contacts guides the mating male pin header into correct alignment before the pins enter the contacts, preventing bent or damaged pins from misaligned insertion. In field-replaceable cable applications, the shroud reduces maintenance errors and extends the service life of the 2.00 mm pitch connector interface.
Which PCB assembly process is the STMM-121-02-F-D-SM designed for?
The SM (surface-mount) suffix indicates the STMM-121-02-F-D-SM is designed for SMT reflow soldering at standard lead-free peak temperatures of 260°C, making it suitable for automated pick-and-place assembly lines where the 42-position connector is placed and soldered alongside other SMT components without manual through-hole operations.
In what types of multi-signal cable interconnect designs is the STMM-121-02-F-D-SM most appropriate?
With 42 positions at 2.00 mm pitch, the STMM-121-02-F-D-SM is appropriate for designs that need more than the 8 to 20 positions offered by smaller STMM variants but fit within a dual-row 2.00 mm pitch footprint — such as ribbon-cable interfaces in industrial PLCs, multi-sensor data acquisition front-ends, or modular embedded computing expansion connectors where 42 digital or analog signals must be routed in a single connector.
