What are the key features of SQW-145-01-FM-D-VS-K-TR?
- 90 positions in a dual-row 2.00 mm pitch configuration providing high signal density for board-to-board connections
- Rugged square-post construction with gold-plated contacts rated for over 30 insertion cycles and up to 3 A per pin
- Tape-and-reel (TR) packaging enabling high-speed automated pick-and-place assembly at production scale
What is SQW-145-01-FM-D-VS-K-TR used for?
The SQW-145-01-FM-D-VS-K-TR is designed for industrial computing modules, mezzanine card stacks, and embedded systems that require a high pin-count, mechanically robust board-to-board socket. Its 2.00 mm pitch strikes a balance between signal density and mechanical strength, making it suitable for avionics, robotics, and test-fixture boards subject to vibration. The 90-position dual-row format accommodates mixed signal, power, and ground lines in a single compact footprint.

Frequently Asked Questions
What pin count and pitch does the SQW-145-01-FM-D-VS-K-TR offer for board-to-board connections?
The SQW-145-01-FM-D-VS-K-TR provides 90 positions arranged in a dual-row configuration on a 2.00 mm pitch. With 45 pins per row, it accommodates large parallel buses and mixed signal-plus-power assignments in a single connector, reducing the board area required compared to using multiple smaller connectors to achieve the same 90-pin count.
How does the rugged square-post design of SQW-145-01-FM-D-VS-K-TR hold up in vibration-prone environments like robotics or automotive test fixtures?
The square-post contact geometry provides four-point wiping action during mating, maintaining a consistent 30-gram minimum contact normal force even after 30 insertion cycles. This resistance to fretting corrosion makes the connector suitable for assemblies that experience continuous vibration between 5 Hz and 500 Hz at amplitudes up to 1 g, as found in robotic arms and automotive test benches, where round-pin sockets can develop intermittent contact over time.
When is the 2.00 mm pitch of SQW-145-01-FM-D-VS-K-TR a better choice than a 1.27 mm pitch alternative for a 90-pin mezzanine stack?
The 2.00 mm pitch provides approximately 2.5 times the contact area and mechanical retention force compared to 1.27 mm pitch counterparts, which is critical when the mezzanine board carries currents above 1 A per pin or must survive shock loads exceeding 50 g during handling. For applications where board-to-board spacing must accommodate components taller than 8 mm on the host board — common in power regulation stages — the wider 2.00 mm pitch posts also simplify mechanical alignment without precision tooling.
