Frequently Asked Questions
What position count and pitch does the SFM-121-T2-SM-D offer?
The SFM-121-T2-SM-D provides 42 positions arranged in a dual-row configuration with a 0.050" (1.27 mm) pitch. This fine-pitch dual-row layout enables high-density connections in compact SMT board-to-board designs requiring up to 42 signal channels.
How does the dual-row configuration of SFM-121-T2-SM-D benefit PCB layout design?
The dual-row arrangement of the SFM-121-T2-SM-D packs 42 positions into a shorter connector body compared to a single-row equivalent, reducing the board length occupied by the connector. With 1.27 mm pitch, designers can achieve high interconnect density while keeping the PCB footprint manageable.
Is SFM-121-T2-SM-D suitable for telecommunications and industrial applications?
Yes. The SFM-121-T2-SM-D is rated as a high-reliability connector, making it appropriate for telecommunications line cards, industrial control boards, and test instrumentation that require 42-channel connectivity with stable contact resistance over extended service lives.
What are the procurement lead time considerations for SAMTEC SFM-121-T2-SM-D connectors?
SAMTEC SFM series connectors, including the 42-position SFM-121-T2-SM-D at 1.27 mm pitch, are typically available through authorized distributors. Buyers should confirm stock levels and MOQ with their preferred SAMTEC distributor, as custom tape-and-reel options may extend lead time beyond 4 weeks.
