What are the key features of SMH-131-02-FM-S-TR?
- 31-position single-row socket at 0.100" (2.54 mm) pitch for compatibility with standard pin headers in industrial and consumer designs
- Horizontal (side-entry) SMT orientation keeps the mating interface parallel to the PCB surface for low-profile assemblies
- Press-fit (FM) contact tails provide solder-free mechanical retention in plated through-holes, simplifying board rework
- Tape-and-reel (TR) packaging for direct compatibility with automated SMT pick-and-place assembly equipment
What is SMH-131-02-FM-S-TR used for?
The SMH-131-02-FM-S-TR is used in board-to-wire and daughter-card interconnects where a horizontal 31-position 0.100" pitch socket is needed at a low mounting height above the PCB surface. Its side-entry orientation suits panel-mounted PCBs inside enclosures where vertical mating clearance is restricted to under 10 mm. The press-fit contact tails allow installation without soldering, making the connector attractive for field-replaceable module designs in industrial and instrumentation equipment.

Frequently Asked Questions
How many positions does the SMH-131-02-FM-S-TR provide and at what contact pitch?
The SMH-131-02-FM-S-TR is a 31-position single-row socket operating at the standard 0.100" (2.54 mm) pitch. This industry-standard spacing ensures compatibility with a wide range of 0.100" pitch male pin headers from multiple manufacturers, simplifying sourcing for prototype and production PCB designs.
What does the horizontal (H) orientation of this socket strip mean for enclosure-constrained PCB designs?
The horizontal orientation means the mating pin enters from the side rather than from above, keeping the connector profile under approximately 5 mm above the PCB surface. This is ideal for boards mounted inside enclosures with height limits below 10 mm, such as panel instruments or slim handheld devices.
How do the press-fit (FM) contact tails of the SMH-131-02-FM-S-TR simplify board-level rework compared to soldered tails?
Press-fit FM tails insert into plated through-holes and are held mechanically without solder, so the connector can be removed with a press tool rather than requiring desoldering. This eliminates thermal stress on nearby SMD components during rework and is particularly valuable on 31-position connectors where desoldering all contacts simultaneously is impractical.
When should an engineer choose the SMH-131-02-FM-S-TR over a vertical-mount SMH socket for the same 31-position application?
The horizontal variant is preferred when the mating cable or pin header approaches the connector from a lateral direction, or when vertical mating clearance is limited to less than 8 mm above the board. Vertical-mount sockets require more headroom but simplify board stacking; the horizontal version better suits edge-facing I/O panels and side-accessible daughtercard slots in rack equipment.
