Frequently Asked Questions
How does the horizontal mounting style of TSM-127-03-H-DH-A-P-TR differ from vertical surface mount strips of the same series?
The H (horizontal) suffix designates a right-angle mating orientation, allowing the 54-position dual-row connector to be accessed from the PCB edge rather than from above, which is essential for panel-mount or rack-mount enclosures where top access to a vertical 2.54 mm pitch connector is restricted.
What is the pin capacity and pitch of TSM-127-03-H-DH-A-P-TR for parallel signal interface designs?
TSM-127-03-H-DH-A-P-TR provides 54 positions in a dual-row horizontal layout at 0.100 inch (2.54 mm) pitch, supporting parallel data buses of up to 27 signals per row, which is sufficient for 24-bit data buses plus control signals in embedded processor designs.
In which application sectors is a 54-position horizontal SMT connector like TSM-127-03-H-DH-A-P-TR commonly specified?
This 54-pin horizontal connector is commonly specified in FPGA development kits, industrial motion controllers, and test and measurement equipment where 2.54 mm pitch dual-row board-edge connectors must accommodate high I/O counts in horizontally accessible panel interfaces.
What makes TSM-127-03-H-DH-A-P-TR suitable for high-volume automated PCB assembly compared to through-hole alternatives?
The SMT termination and tape and reel (TR) packaging allow TSM-127-03-H-DH-A-P-TR to feed directly into automated pick-and-place machines and reflow ovens at up to 260°C, eliminating the hand-insertion step required for through-hole 54-pin dual-row connectors and reducing assembly cost per unit.
