What are the key features of TSM-133-03-H-SH-A?
- 33-position dual-row SMT terminal strip at 0.100 inch (2.54 mm) pitch in horizontal (H) orientation for board-edge signal routing applications
- Single-row horizontal (SH) mounting style enables side-entry connections, saving vertical board space and enabling panel-mounted or edge-connector configurations
- Additional plating (A) option provides enhanced contact surface protection for improved corrosion resistance and long-term reliability in demanding SMT applications
What is TSM-133-03-H-SH-A used for?
The TSM-133-03-H-SH-A is designed for horizontal board-edge interconnects in embedded computing boards, industrial I/O expansion modules, and signal distribution panels where 33-pin SMT connections at 2.54 mm pitch with a low-height side-entry profile are required. Its horizontal orientation is advantageous in slim enclosures and panel-mounted electronics where vertical connector height must be minimized. The connector is also used in rack-mounted systems, PLC interface boards, and communication equipment requiring reliable SMT edge connections with enhanced contact plating.

Frequently Asked Questions
What does the SH designator indicate in TSM-133-03-H-SH-A and how does it affect board layout?
SH stands for single-row horizontal, indicating that the connector's mating interface exits from the side of the PCB rather than vertically. This horizontal orientation is critical for edge-connector applications where overall assembly height must be kept below a few millimeters, and for 33-contact SMT designs in slim panel-mounted enclosures where vertical clearance is limited.
How many contacts does the TSM-133-03-H-SH-A provide and at what pitch?
The TSM-133-03-H-SH-A provides 33 contacts at 0.100 inch (2.54 mm) pitch in a dual-row surface-mount configuration. This standard pitch ensures compatibility with a wide range of mating connectors and flat flexible cables, while the dual-row layout allows 33 signal or power channels in a compact SMT footprint for horizontal board-edge connections.
For which applications should engineers choose TSM-133-03-H-SH-A over a vertical SMT connector?
Engineers should choose the TSM-133-03-H-SH-A over a vertical SMT connector when the PCB is panel-mounted inside a slim enclosure and mating cables or connectors must approach from the side rather than top. At 33 contacts and 2.54 mm pitch, this horizontal SMT terminal strip is ideal for I/O expansion cards, industrial control front panels, and rack-mounted boards where overall system height is a critical design constraint.
Does the additional plating (A) option on TSM-133-03-H-SH-A improve performance in harsh environments?
Yes, the A (additional plating) option on TSM-133-03-H-SH-A adds an extra layer of contact surface protection beyond the standard gold or tin plating, improving corrosion resistance in environments with elevated humidity, salt air, or mild chemical exposure. For 33-contact SMT connectors at 2.54 mm pitch deployed in outdoor industrial or marine applications, this extra plating can extend service life by several years compared to standard-plated variants.
