What are the key features of STMM-124-02-S-D-SM?
- 48-position dual-row male pin layout on 2.00 mm pitch in a compact 2.132 inch body for high-density cable-to-board routing
- Tin (Sn) over nickel (Ni) barrier contact finish provides corrosion resistance and reliable low-resistance mating
- Surface mount termination enables automated reflow soldering integration and eliminates through-hole drilling cost
What is STMM-124-02-S-D-SM used for?
The STMM-124-02-S-D-SM is designed for wire-to-board assemblies in industrial automation controllers, robotics harnesses, and medical instrument panels requiring a compact 2.00 mm pitch connector that supports 48 signal or power lines in a dual-row surface mount body. The tin-over-nickel contact finish maintains stable contact resistance over extended service life in environments with moderate humidity and temperature cycling. Its shrouded male header mates with compatible female cable connectors, supporting quick-disconnect servicing in the field.

Frequently Asked Questions
What contact finish does the STMM-124-02-S-D-SM use, and how does it affect mating reliability over time?
The STMM-124-02-S-D-SM uses tin (Sn) over a nickel (Ni) barrier contact finish. The nickel underlayer prevents tin diffusion into the copper base, maintaining a stable contact interface with typical insertion resistance below 20 milliohms throughout thousands of mating cycles. This finish suits moderate-duty applications where gold-plated contacts would be cost-prohibitive.
How long is the STMM-124-02-S-D-SM body, and how does its physical size influence PCB layout?
The STMM-124-02-S-D-SM body measures 2.132 inches (54.2 mm) in length and 0.429 inch (10.9 mm) in depth, with 48 pins arranged in 2 rows of 24 on a 2.00 mm pitch. This footprint fits within a standard 55 mm edge clearance zone on most PCB designs and the SMT pads add minimal board real estate compared to an equivalent through-hole connector requiring drilled holes.
In which industrial or robotic applications is the 48-pin STMM-124-02-S-D-SM preferable to smaller connector alternatives?
When a system needs to carry 48 discrete I/O signals, motor phase lines, or mixed power-and-signal channels across a single cable break point, the STMM-124-02-S-D-SM consolidates all connections into one 2.00 mm pitch shrouded connector body. This reduces harness complexity compared to using three or four smaller 12-16 pin connectors, and the shroud prevents dangerous mismating in high-cycle machine tool or collaborative robot environments where repeated cable connection is routine.
