Frequently Asked Questions
Why does the TSM-129-04-LM-DH-A-K-TR use low-magnetic contacts, and in which applications does this matter?
The TSM-129-04-LM-DH-A-K-TR uses low-magnetic (LM) contact materials to minimize magnetic field interference generated by the 58-position connector. This is critical in scientific instrumentation, magnetometers, MRI-adjacent electronics, and precision sensor boards where standard nickel or iron-bearing contacts would distort nearby magnetic measurements.
How does the keyed housing of the TSM-129-04-LM-DH-A-K-TR prevent assembly errors on boards with multiple connectors?
The keying (K) feature in the TSM-129-04-LM-DH-A-K-TR mechanically blocks incorrect mating of the 58-position 0.100" pitch dual-row connector. Boards with multiple similar headers benefit from keyed polarization to prevent miswiring during production or field maintenance, reducing potential damage to sensitive electronics.
Can the TSM-129-04-LM-DH-A-K-TR be placed by automated pick-and-place equipment in a standard SMT production line?
Yes, the TSM-129-04-LM-DH-A-K-TR is supplied in tape-and-reel (TR) format and uses surface mount termination, making it directly compatible with automated SMT pick-and-place equipment. The 58-position dual-row 0.100" pitch connector can be reflowed in standard lead-free SMT processes for high-volume PCB manufacturing.
What is the procurement lead time difference between TSM-129-04-LM-DH-A-K-TR and non-LM TSM series variants for production planning?
Low-magnetic (LM) variants of the SAMTEC TSM series like the TSM-129-04-LM-DH-A-K-TR are specialty configurations that may carry longer factory lead times than standard contact options. Production planners should verify current lead time with SAMTEC or authorized distributors when scheduling builds with this 58-position, 0.100" pitch low-magnetic connector.
