What are the key features of STMM-125-02-F-D-SM-K-TR?
- 50-position dual-row shrouded terminal strip at 2.00 mm pitch, providing polarized and keyed cable mate connectivity for error-free assembly in high-density board interconnect designs
- Tin (Sn) over Nickel (Ni) barrier contact finish on square-pin male contacts ensures corrosion resistance and maintains low contact resistance across industrial temperature ranges
- 2.193-inch body length in a surface mount configuration enables high-density cable-to-board termination compatible with automated SMT reflow assembly processes
What is STMM-125-02-F-D-SM-K-TR used for?
STMM-125-02-F-D-SM-K-TR is used in cable-to-board interfaces for industrial control systems, embedded computing platforms, and test and measurement instruments requiring reliable 50-position connectivity at 2.00 mm pitch. Its shrouded housing prevents mis-mating during cable connection, making it suitable for maintenance-heavy field equipment where harness orientation errors would be costly. The SMT footprint integrates smoothly into automated PCB production workflows.

Frequently Asked Questions
How many positions and what pitch does STMM-125-02-F-D-SM-K-TR offer in its dual-row layout?
STMM-125-02-F-D-SM-K-TR provides 50 positions arranged in a dual-row configuration with 2.00 mm pitch, giving 25 pins per row. The 2.193-inch body length accommodates all 50 contacts for high-density cable-to-board connections in industrial and computing applications.
What does the shrouded housing on STMM-125-02-F-D-SM-K-TR prevent, and why does it matter in field equipment?
The shrouded housing on STMM-125-02-F-D-SM-K-TR mechanically guides the mating cable connector into the correct orientation, preventing mis-insertion of 50 pins during field servicing or harness replacement. This is critical in industrial equipment where incorrect connector orientation could damage sensitive electronics or disrupt production.
What are the key body dimensions of STMM-125-02-F-D-SM-K-TR for PCB footprint design?
STMM-125-02-F-D-SM-K-TR has a body length of 2.193 inches, a breadth of 0.237 inches, and a depth of 0.24 inches. The 2.00 mm dual-row pitch over 50 positions determines the contact pad grid, and the SMT mounting format requires a reflow-compatible solder pad layout for proper PCB integration.
When would STMM-125-02-F-D-SM-K-TR be selected over an unshrouded terminal strip of the same pin count?
STMM-125-02-F-D-SM-K-TR would be selected over an unshrouded strip when cable harness mis-mating is a risk, particularly in 50-pin systems where reverse insertion could damage circuitry. The shroud and keying features add physical protection without significantly increasing the 2.193-inch footprint, making it the better choice in field-serviceable or rack-mounted equipment.
