• Light 1.209g weight won't put unnecessary pressure on your circuit board
• 4.2mm pitch interface suits high-density wire arrangements
• Wide operating temperature range between -40°C and +105°C for use in demanding systems
Applications
• Research and development facilities
• Domestic appliances
• Lighting systems
• Manufacturing machinery
What's a wire-to-board system?
A wire-to-board connector system is a way to connect a wire to a printed circuit board, meaning you can send power and signals between circuits. It's an important component in any PCB design.
