Frequently Asked Questions

How many positions does the STMM-112-02-L-D-SM-K-TR support and how are they arranged?

The STMM-112-02-L-D-SM-K-TR provides 24 positions arranged in a dual-row rectangular pattern with a body length of 1.179 inches. This layout allows dense signal routing in a compact SMT footprint suitable for mezzanine and board-to-board interconnects.

Why is the square pin-socket contact style in the STMM-112-02-L-D-SM-K-TR beneficial for mating reliability?

The square pin-socket (SQ PIN-SKT) contact geometry provides four-point contact with the mating receptacle, increasing normal force and reducing contact resistance compared to round pins. This design maintains reliable electrical connections over repeated mating cycles and in vibration-prone environments with 24 positions engaged simultaneously.

For which production environments does the tape-and-reel packaging of the STMM-112-02-L-D-SM-K-TR provide the best advantage?

The -TR (tape-and-reel) designation makes the STMM-112-02-L-D-SM-K-TR directly compatible with automated SMT pick-and-place machines, enabling placement rates of thousands of connectors per hour. This reduces handling costs and improves positional accuracy during reflow soldering of the tin-over-nickel termination contacts.

What board space must be allocated for the STMM-112-02-L-D-SM-K-TR during PCB layout?

The connector body measures 1.179 inches in length, 0.24 inches in depth, and 0.237 inches in breadth. PCB layout engineers must reserve at least this footprint area plus solder pad extensions to properly place this 24-position dual-row SMT connector without spacing violations.
