Frequently Asked Questions
What contact finish does the SQT-108-01-FM-D use, and how does this affect connector life?
The SQT-108-01-FM-D uses gold flash mating contacts with a nickel barrier and tin termination finish. Gold flash plating reduces contact resistance and provides corrosion resistance over hundreds of mating cycles, while the nickel barrier prevents tin migration into the gold layer, extending reliable contact life in the 16-position 2.00 mm pitch socket.
How does the 2.00 mm pitch of the SQT-108-01-FM-D compare to the standard 2.54 mm pitch for PCB area efficiency?
At 2.00 mm pitch, the SQT-108-01-FM-D occupies approximately 21% less board length than an equivalent 2.54 mm pitch connector for the same 16 positions. The body length of 0.642 inch (approximately 16.3 mm) illustrates this compactness, making it advantageous for dense PCBs in embedded computing and industrial control designs where board space is limited.
In what rugged applications is the SQT-108-01-FM-D preferred over a standard low-cost socket?
The SQT-108-01-FM-D is preferred in robotics control boards, vibration-exposed industrial equipment, and field-service test fixtures where the 16-position socket must survive repeated mating cycles and mechanical shock. Its rugged housing and gold flash contacts outperform standard sockets in environments with temperatures from -55°C to +125°C and high-vibration conditions.
What are the key body dimensions of the SQT-108-01-FM-D for PCB footprint planning?
The SQT-108-01-FM-D body measures 0.642 inch (16.3 mm) in length, 0.157 inch (3.99 mm) in breadth, and 0.079 inch (2.0 mm) in depth. These dimensions guide pad placement for the 16-position dual-row 2.00 mm pitch footprint, ensuring correct mechanical clearance and reliable soldering in automated PCB assembly processes.
