Samtec ESQ Series Straight Through Hole Mount PCB Socket, 40-Contact, 2-Row, 2.54mm Pitch, Solder Termination

From Samtec, these ESQ series are elevated stackthrough or 'self nesting' PC/104 sockets with a 2.54mm pitch that offer an easy and efficient way to accommodate multi-way board to board connections. These ESQ series PC/104 double row sockets have black glass filled polyester housings, gold plated contacts, square tails and accept 0.64mm square pins for board to board applications and are available with a low or standard insertion force and with various lead styles (please refer to datasheet for details)
For mating connectors see:
DW series PCB headers (stock number 277-9720 typically)
EW series PCB headers (stock number 277-9742 typically)
TSM series PCB headers (stock number 765-6423 typically)
TSW series PCB headers (stock number 767-0820 typically)

Connect two circuit boards in a jiffy with this Samtec PCB socket. When mated with a compatible header, it helps to ensure a durable connection for open lines of communication between your circuit boards. As the unit is self-nesting, its tails pass through a PCB and plug into each other. This makes it a cinch to build, stack or expand a complete system with fewer components. Its Tiger Buy contacts give you superior retention force, which cuts down on the chance of your connections working loose.

• Black glass-filled polyester housing offers insulation for protection against electric shocks
• Safe for use in demanding locations, thanks to a broad operating temperature range between -55°C and +125°C
• Low insertion force of 0.92N to make assembly a cinch

• Networking hubs
• Military equipment
• Aerospace engineering
• Industrial manufacturing

It has robust phosphor bronze contacts that are highly conductive and resistant to corrosion, helping to ensure a reliable electrical connection.
