Frequently Asked Questions
How many positions and what pitch does the TSM-128-04-FM-DH-P-TR provide?
The TSM-128-04-FM-DH-P-TR is a 56-position dual-row surface mount terminal strip with a standard 0.100 inch (2.54 mm) pitch. This spacing accommodates a wide range of standard wire gauges and mating connectors, making it compatible with the majority of 0.100 inch pitch connector ecosystems used in industrial and commercial electronics.
What does the FM (Friction Mount) designation mean for board retention?
FM stands for Friction Mount, meaning the connector relies on interference fit between the housing and the PCB holes or pads to maintain mechanical stability prior to and during soldering. This eliminates the need for additional retention clips or hardware, simplifying assembly for 56-position configurations and reducing total component count on the PCB.
Why is the tape-and-reel (-TR) version preferred for automated assembly lines?
The -TR suffix indicates tape-and-reel packaging, enabling automated pick-and-place equipment to handle the TSM-128-04-FM-DH-P-TR at high speed and accuracy. This format supports SMT reflow soldering processes, minimizes handling errors, and is essential for high-volume production runs where manual placement of 56-position connectors would introduce variability and increase assembly time.
When should designers specify the polarized dual-height (DH-P) variant over a standard single-height version?
The DH-P polarized dual-height variant should be chosen when preventing incorrect connector mating orientation is critical, such as in mixed-signal or power applications where incorrect insertion could damage circuits. The dual-height profile also provides additional mechanical keying over standard single-height 0.100 inch connectors, reducing field assembly errors in systems with 56-pin interfaces.
