Frequently Asked Questions
What pitch and row configuration does STMM-125-02-G-D-SM-K-TR use for board connections?
The STMM-125-02-G-D-SM-K-TR uses 2.00mm pitch in a dual-row configuration, providing 50 positions total across a body length of 2.193 inches (55.7mm), making it suitable for high-position-count cable-to-board connections in industrial and embedded systems.
What contact finish does STMM-125-02-G-D-SM-K-TR use and how does it affect connector reliability?
The termination contacts use gold plated over a nickel barrier, which provides corrosion resistance and low contact resistance over thousands of mating cycles, ensuring reliable signal integrity in industrial environments subject to humidity, vibration, or repeated cable disconnection.
For which cable-to-board applications is the shrouded design of STMM-125-02-G-D-SM-K-TR most beneficial?
The polarized shroud prevents incorrect cable orientation during field installation, making it ideal for robotics harnesses, motor-drive controller connections, and industrial fieldbus wiring where mis-insertion could damage 50-position signal lines or cause system faults.
How does the 2.00mm pitch of STMM-125-02-G-D-SM-K-TR compare to tighter-pitch alternatives for 50-position designs?
At 2.00mm pitch, the 50-position dual-row STMM-125-02-G-D-SM-K-TR spans 2.193 inches (about 55.7mm), whereas a 1.27mm-pitch equivalent would measure roughly 35mm, but the larger pitch offers easier field wiring with standard 24 AWG to 28 AWG wire and better mechanical robustness in vibrating assemblies.
