Frequently Asked Questions
What is the position count and pitch of the TSM-123-03-SM-DH-P-TR terminal strip?
The TSM-123-03-SM-DH-P-TR is a 46-position surface-mount terminal strip with a 0.100" (2.54 mm) pitch. This standard 2.54 mm spacing ensures broad compatibility with industry-standard mating headers while accommodating 46 signal channels in a single connector for high-density board interconnects.
How does the polarization feature of TSM-123-03-SM-DH-P-TR prevent assembly errors?
The polarization (P) feature of TSM-123-03-SM-DH-P-TR incorporates a keying mechanism that physically prevents the mating connector from being inserted in the wrong orientation. This eliminates the risk of reversed connections across 46 positions at 2.54 mm pitch, reducing costly assembly errors on production PCBs.
Is TSM-123-03-SM-DH-P-TR suitable for high-volume automated production?
Yes. The -TR (tape-and-reel) packaging of TSM-123-03-SM-DH-P-TR allows direct use with automated SMT pick-and-place machines, enabling efficient and accurate placement of the 46-position connector in high-volume manufacturing environments. This eliminates manual loading and reduces placement cycle time significantly.
How does TSM-123-03-SM-DH-P-TR compare to standard-height TSM variants in vibration-prone applications?
The dual-height (DH) housing of TSM-123-03-SM-DH-P-TR increases the insulator body height compared to standard-height TSM variants, providing greater contact area with the mating header and improving connector retention force. In vibration-prone industrial environments, this reduces the risk of intermittent contact across the 46-position, 2.54 mm pitch interface during operation.
