Frequently Asked Questions
What role does the keying feature of the TSM-128-03-SS-DH-A-K-TR play in industrial field assembly?
The keying feature (K option) of the TSM-128-03-SS-DH-A-K-TR physically prevents incorrect mating of the 56-position dual-row 0.100" pitch connector, reducing the risk of assembly errors that could damage boards or cause signal miswiring. This is especially valuable in field-serviceable industrial equipment with multiple similar connectors.
How does the stainless steel hardware option affect the durability of the TSM-128-03-SS-DH-A-K-TR in demanding environments?
The stainless steel (SS) hardware in the TSM-128-03-SS-DH-A-K-TR provides enhanced mechanical strength and corrosion resistance compared to standard brass hardware. This makes the 56-position 0.100" pitch surface mount terminal strip better suited for industrial environments with humidity, chemical exposure, or repeated physical stress during mating cycles.
Is the TSM-128-03-SS-DH-A-K-TR suitable for automated SMT assembly, and does it come in reel packaging?
Yes, the TSM-128-03-SS-DH-A-K-TR is a surface mount connector supplied in tape-and-reel (TR) format, making it fully compatible with automated SMT pick-and-place machines. For production quantities of this 56-position 0.100" pitch dual-row strip, the T&R packaging enables continuous feeder-based assembly without manual loading.
How many signals can the dual-row configuration of the TSM-128-03-SS-DH-A-K-TR route on a standard 0.100" pitch footprint?
The TSM-128-03-SS-DH-A-K-TR accommodates 56 positions in a dual-row 0.100" (2.54 mm) pitch layout, providing 56 individual signal or power contacts within a compact PCB footprint. This dual-row approach halves the connector's row length compared to a single-row 56-pin strip at the same pitch, saving board real estate.
