Frequently Asked Questions
What does the K (locking) option on the TSM-127-02-L-DH-A-K-TR add to the connector's mechanical performance?
The K locking feature on the TSM-127-02-L-DH-A-K-TR provides positive mechanical retention that prevents accidental disconnection across all 54 positions at 2.54 mm pitch. This is critical in high-vibration environments such as industrial machinery or vehicle-mounted electronics where an unintentional disconnect could cause system faults or safety issues.
How does the angled termination (A) in TSM-127-02-L-DH-A-K-TR differ from straight-body configurations for PCB layout?
The angled (A) termination on TSM-127-02-L-DH-A-K-TR routes the solder tails at an angle relative to the connector body, which allows the PCB designer to route traces from the 54-position 2.54 mm pitch footprint along a different axis than a straight-body configuration. This reduces routing congestion in constrained dual-row PCB designs.
For which applications is the dual-row 54-position layout of TSM-127-02-L-DH-A-K-TR preferred over single-row alternatives?
The dual-row 54-position layout in the TSM-127-02-L-DH-A-K-TR is preferred when a design requires more than 27 signals per connector body length while minimizing the physical connector width at 2.54 mm pitch. This is common in modular backplane designs, industrial PLC I/O cards, and embedded computing modules where board real estate limits the connector footprint.
Does the TSM-127-02-L-DH-A-K-TR comply with RoHS requirements for lead-free electronics manufacturing?
The TSM-127-02-L-DH-A-K-TR is an active RoHS-compliant product in SAMTEC's TSM terminal strip series, featuring lead-free terminations suitable for lead-free solder reflow at standard SMT process temperatures. Its tape-and-reel packaging and 54-position dual-row 2.54 mm pitch footprint are designed for integration into modern green electronics manufacturing workflows.
